I-Snowblower Auger Clog kunye ne-Chute Clearing Amputation Ingozi¶

Rhoqo ebusika, amawaka-waka abanini-zindlu kunye nabasebenzi bezorhwebo bachaphazeleka kanobom kukunqunyulwa kwamalungu omzimba, ukwaphuka okuvulekileyo, kunye neminxeba eqatha yezicubu ezithambileyo ezivela kubaphuhlisi bekhephu. Uhlolo lwezempilo lukawonke-wonke oluvela kumasebe onxunguphalo olungxamisekileyo amaxwebhu abonisa ukuba ukwenzakala kwekhephu kulandele ipateni engaguqukiyo: ngaphezulu kweepesenti ezingama-80 kubandakanya ukonzakala kwisandla esilawulayo neminwe, kwaye ngaphezulu kweepesenti ezingama-60 zenzeka xa umqhubi ecima ngabom i-injini aze afikelele ngqo kwi-chute yokukhupha ukuze asuse ikhephu elimanzi, elixineneyo.

Iinqwelo-moya zekhephu zenziwe ukuba zicande kwimisinga exineneyo, zihlafune kwiindonga zomkhenkce ezikhenkcezileyo, zize zijike udaka olunzima kumgama oziimitha eziyi-10 ukuya kwezili-15 (iinyawo ezingama-33 ukuya kwezingama-50). Amandla oomatshini afunekayo ukufezekisa oku kuphosa kwenza iibhleyidi ezijikelezayo zangaphakathi zingaxoleli. Nasemva kokuba i-injini ivaliwe kwaye isitshixo sokutshisa sitsaliwe, ukunyanzeliswa okujikelezayo okugcinwe kwi-drivetrain kunokubangela ukuba i-impeller yentsimbi ibuyele ngobudlova i-20 ukuya kwi-90 degrees ngexesha elihlangeneyo lekhephu liyachithwa. Le ndlela, eyaziwa ngokuba yi-impeller spring-back trap, ihlukanisa iminwe yomntu kumashumi eemitha, ngokukhawuleza kunokuba iimpembelelo zemithambo-luvo yomntu zinokutsala isandla.

Yenza oku ngoku¶

1. Misa i-injini ngoko nangoko kwaye ukhuphe zonke izithinteli zokuqhuba. Khupha ibheyile yolawulo lwe-auger kunye nebheyile yokutsalela kwikhonsoli yomsebenzisi. Cima iqhosha lokulayita ukuze ucime okanye ucofe iqhosha lokumisa injini.
2. Susa iqhosha lokhuseleko leplastiki kwaye uqhawule ucingo lwentlantsi yeplagi. Tsala ibhutsi yerabha ngokuqinileyo kwincam yeplagi yentlantsi kwaye ukhusele ucingo kude netheminali. Kwizitshizi zekhephu zombane ezinamandla ebhetri, khupha ipakethe yebhetri ye-lithium-ion ephezulu yombane ngaphambi kokuba uchukumise nayiphi na indawo yendlu.
3. Linda ubuncinci imizuzwana elishumi ukuze onke amalungu angaphakathi ame ngokupheleleyo. Bukela i-chute yokukhutshwa kwaye umamele ngenyameko. Inertia ejikelezayo inokugcina ii-impellers zangaphakathi zijikeleza ngokuzolileyo nasemva kokuba isandi se-injini siphelile.
4. Ungaze ufikelele isandla, umnwe, okanye unyawo kwi-chute, i-impeller housing, okanye i-auger assembly yangaphambili. Phatha iqhina ngalinye njengequla eligcweleyo phantsi koxinzelelo olukhulu lomatshini. Ayenzi mahluko nokuba isandla sakho si ze okanye sigqunywe yiglavu eshinyeneyo yesikhumba.
5. *Sula indawo evalelekileyo usebenzisa intonga ezinikeleyo yokucoca okanye isixhobo somthi. Sebenzisa iplanga ebonelelwe ngumzi-mveliso yeplastiki yokubheqa ebotshelelwe kwindlu okanye idowel ecocekileyo eyenziwe ngomthi okanye umphini womtshayelo. Yima ngokuqinileyo ecaleni komatshini, gcina ibhalansi yakho kumhlaba omtyibilizi, kwaye ucoce ikhephu elipakishiweyo kwindawo ephezulu.
6. Ukuba isandla okanye idijithi iyabanjiswa, musa ukujikelisa ilungu ngasemva kwincam yentsimbi. Ukutsalwa kwesandla esityumkileyo kwincakuba ye-impeller kubangela ukuqhawuka kwe-second degloving kunye ne-tendon transection. Vala umatshini, uqhawule ucingo lwe-spark plug, kwaye usebenzise i-wedge yokhuni okanye i-wrench kwi-pulley nut ukuze ujikeleze ngobunono i-impeller ngasemva ngokwaneleyo ukukhulula uxinzelelo.
7. *Lawula ukopha okukhulu ngoko nangoko kwaye ukhusele izicubu eziqhawuleyo ekukhenkceni. Faka uxinzelelo oluqinileyo oluqhubekayo kunye neelokhwe ezingenazintsholongwane okanye ilaphu elicocekileyo. Ukuba umnwe okanye idijithi inqunyulwe, qokelela inxalenye kwi-chute, uyisongele nge-saline ye-saline emanzi, uyitywine ngaphakathi kweplastiki eyomileyo, kwaye ubeke loo ngxowa kwindawo eludaka lwamanzi omkhenkce. Ungaze ungcwabe izicubu ezinqunyulwe ngokuthe ngqo kwikhephu elingenanto okanye umkhenkce owomileyo.

I-biomechanics kunye nefiziksi yokonzakala kokunqunyulwa kwekhephu¶

Ukulimala kwe-snowblower kwahlulwe kwi-snowcuts elula ngobukhulu bamandla omatshini adluliselwe kwizakhiwo zomntu ze-musculoskeletal. Abathengi bale mihla abagibisela ikhephu bamanqanaba amabini basebenzisa iinjini zokutsha zangaphakathi ezinemivimbo emincinci ukusuka kwi-200 ukuya kuma-420 cubic centimeters (zikhupha malunga ne-4.5 ukuya kwi-11 kilowatts, okanye amandla ama-6 ukuya kwi-15), okanye iinjini zombane ezingenabrushless ezikwaziyo ukuzisa itorque elinganayo ngoko nangoko. La mandla aqhuba amacandelo amabini ahlukeneyo ajikelezayo: i-auger yokuqokelela isantya esisezantsi kunye ne-impeller yokukhutshwa kwesantya esiphezulu.

       Rotational Kinetic Energy Equation:

       E_k = 0.5 * I * (omega squared)

       Where:
       E_k   = Kinetic Energy in Joules (J)
       I     = Moment of Inertia of the steel impeller assembly (kg m squared)
       omega = Angular velocity in radians per second (rad/s)

I-impeller yenqanaba lesibini ngokuqhelekileyo ibandakanya i-blade yentsimbi emithathu okanye i-4-blade edibeneyo yentsimbi enomlinganiselo we-300 mm (i-intshi ezili-12) ububanzi. Xa i-injini isebenza ngesantya serhuluneli esilinganisiweyo se-3,600 revolutions ngomzuzu (RPM), i-pulley yokunciphisa ibhanti ye-drive ijikelezisa i-shaft ye-impeller malunga ne-1,100 ukuya kwi-1,200 RPM. Ngeli xesha lokujikeleza, isantya se-peripheral tip of steel blades sidlula i-18.8 metres ngesekhondi (67.7 km / h okanye 42.1 mph).

Ubukhulu be-350 mm (i-14-intshi) i-impellers zorhwebo ezisebenza kwi-RPM efanayo, isantya se-tip sifikelela kwi-22.0 yeemitha ngesekhondi (79.2 km / h okanye 49.2 mph). Xa umnwe womntu okanye isandla sinxibelelana nomphetho ohamba kwesi santya ngaphakathi kwentsimbi ethintelweyo yombhobho we-chute yokukhupha, ukuhanjiswa kwamandla e-kinetic kwenzeka kwii-milliseconds. Amandla empembelelo yendibano ye-impeller kunye nomzuzwana we-inertia malunga ne-0.04 kg ye-squad spinning kwisantya sokusebenza idlula i-315 Joules. Ukuthelekisa, i-distal phalanx bone fractures phantsi komthwalo we-static compressive we-1,500 kuphela kwi-2,000 ye-Newtons, kunye nokucheba kwamathambo kufuna ngaphantsi kwe-40 ukuya kwi-60 Joules yamandla ashukumisayo asekuhlaleni.

Amaziko omonzakalo ahlela umonzakalo wezandla we-snowblower kwiindlela ezine ezinzima ze-pathological: - Ukunqunyulwa kweSikhwelo esikwisantya esiphezulu: Umphetho obukhali wencakuba ye-impeller ejikelezayo ucheba ulusu, i-extensor kunye ne-flexor tendons, i-digital neurovascular bundles, kunye ne-phalangeal bone cortices kumlebe omileyo we-chute housing. - I-Crush and Avulsion Degloving: I-impeller blade ibamba izicubu ezithambileyo kumbhobho wentsimbi, isikhumba esihlubayo kunye namafutha angaphantsi kwi-subcutaneous kude nemisipha engaphantsi kunye namathambo njengeglavu etsalwa ngaphakathi ngaphandle. - IiNgxaki eziMaqhekeza amaqhekeza amaninzi: Itorque ejikelezayo ivelisa ukuhlangana okuqatha kwephalanges esondele, ephakathi, kunye nekude, ukutyumza ithambo libe ngamaqhekeza amaninzi angaqhelekanga angcoliswe ludaka, igrisi, kunye negrit yesitrato. - I-Microvascular Thrombosis kunye ne-Cold Ischemia: Ukwenzakala okukhulu okutyumzayo kuphazamisa i-endothelial lining ye-digital arteries enokulinganisa kuphela i-1 mm (0.04 intshi) ububanzi. Ukuba sesichengeni kumaqondo obushushu angaphantsi kwe-0 °C (32 °F) kubangela ukuqina kwe-reflex vasoconstriction, i-accelerating platelet aggregation kunye ne-microvascular clotting epheleleyo.

I-impeller blade spring-back trap: Kutheni oomatshini abacinyiweyo baqhawula iminwe¶

Eyona mbono iyingozi kakhulu phakathi kwabaqhubi bekhephu yinkolelo yokuba ukucima i-injini kuqinisekisa ukhuseleko lomntu. Izifundo ze-Epidemiological ezivela kwi-American Academy of Orthopedic Surgeons kunye namaziko okwenzakala kwezandla zityhila ukuba ngaphezu kwe-60 pesenti yokunqunyulwa kwe-snowblower kwenzeka emva kokuba umqhubi evale ngabom injini yepetroli. Umsebenzisi uvala isitshixo sokulayita, eva ukuma kwe-injini, ajonge ezantsi kwi-chute yokukhupha, aze afikelele kwisandla kwiplagi yekhephu. Ngokukhawuleza ukuba ikhephu elipakishwe ngesandla litsalwa likhululekile, i-impeller yentsimbi ibetha ngamandla ngaphambili okanye ibuyele ngasemva nge-arc ye-20 ukuya kwi-90 degrees. Lo mcimbi waziwa ngonyango nangoomatshini njenge impeller spring-back trap.

Xa imanzi, i-slush enzima ipakisha kwi-cylindrical impeller housing, i-blade ejikelezayo isebenza njenge-wedge yomatshini. Ikhephu lixinanisela kwibloko yomkhenkce eshinyeneyo phakathi kwencam yencakuba kunye nodonga lwezindlu olugobileyo (apho ukunyamezelwa kwemvume ngokuqhelekileyo kuphela yi-3 mm ukuya kwi-6 mm, okanye i-0.12 ukuya kwi-0.24 intshi). Njengoko i-injini yokuthengisa okanye ibhanti lityibilika, itorque enkulu ejikelezayo ihlala ivaleleke ngaphakathi kumatshini.

Amalungu amathathu ahlukeneyo agcina la mandla anokubakho ngoomatshini: 1. I-Drive Belt Elasticity: Ibhanti yerabha enzima engu-V edibanisa ipuli ye-crankshaft ye-injini ukuya kwipuli ye-impeller drive yoluliwe yada yaphantsi koxinzelelo. Xa i-impeller jams, ibhanti lisebenza njengebhande lerabha elide phantsi kwamakhulu eeNewtons zomthwalo onzima. 2. I-Drivetrain Torsional Deflection: Iishafti zentsimbi zokuqhuba, iipuli, kunye namalungu ebhokisi yegiya yeentshulube zityhutyha ukuqina kwe-elastic torsional, zijijeka kancinane phantsi kwetorque yokuma yenjini yamahashe amaninzi. 3. Iplagi yekhephu eCompressive Preload: Iplagi yomkhenkce egayiweyo ngokwayo isebenza njengeweji yesakhiwo ecinezelweyo ebambe incakuba yentsimbi kwindawo engeyoyendalo, ejikisiweyo.

Xa umqhubi efika ezantsi kwi-chute aze akhulule iplagi yekhephu ngeminwe yakhe, ulungelelwaniso lomatshini luyawa ngoko nangoko. I-elasticity egciniweyo kwibhanti yedrayivu eyoluliweyo kunye nezixhobo ezijijekileyo zokuqhuba zikhupha ngoko nangoko. Intsimbi yentsimbi ibuyela phambili okanye ngasemva kwisithuba esingaphantsi kwe-20 ukuya kwi-40 milliseconds.

Umntu akakwazi ukutsala isandla sakhe umva ngokukhawuleza ngokwaneleyo ukuphepha ukwenzakala. Ixesha le-Physiological reaction liqukethe i-sensory nerve transmission (i-20 ukuya kwi-30 millisecond), inkqubo ye-nervous system processing (100 ukuya kwi-150 milliseconds), kunye ne-muscular contraction of forearm flexors (50 ukuya kwi-100 millisecond). Impendulo epheleleyo yokuhoxiswa komntu idinga ubuncinci be-170 kwi-280 millisecond phantsi kweemeko ezifanelekileyo. Incakuba ehexayo ibetha ize iqhawule iminwe ngokukhawuleza ngokuphindwe kalishumi kunokuba inkqubo yemithambo-luvo inokudlulisela umqondiso wokuba isuke.

Ubunjineli be-snowblower: Inqanaba elinye, inqanaba elinye, kunye nezigaba ezintathu zokwakha¶

Oomatshini bokususwa kwekhephu bahluka kakhulu kuyilo, ukubekwa kwe-drivetrain, kunye neeprofayili ezinobungozi. Ukuqonda ukungafani komatshini phakathi kweeklasi zoomatshini kuvumela abaqhubi ukuba bahlole umngcipheko kwaye benze ukugcinwa okufanelekileyo.

Abagibi bekhephu abakwinqanaba elinye¶

Oomatshini abakwinqanaba elinye ziiyunithi ezikhaphukhaphu ezenzelwe ikakhulu ukucoca ikhephu elikhanyayo kwiidriveways ezigangathiweyo kunye neendlela zokuhamba. Zibonisa i-rotor enye enesantya esiphezulu esithe tyaba ene-curved, irabha eyomeleziweyo okanye i-polyurethane paddles. Le rotor isebenza ngeenjongo ezimbini ngaxeshanye: ibheqa ikhephu kwizindlu zoomatshini kwaye iyiphose ngokuthe ngqo nge-chute yokukhupha kwintshukumo eqhubekayo. I-rotor inxibelelana nomhlaba ngokuthe ngqo, onceda ukuqhubela phambili umatshini.

Ngenxa yokuba oomatshini benqanaba elinye abanayo inqanaba lesibini elahlukileyo lentsimbi ye-impeller fan kwaye basebenza ngamabhanti amafutshane, ngokuthe ngqo, i-spring-back phenomenon ayibi kakhulu kunoomatshini bamanqanaba amaninzi. Nangona kunjalo, iipaddles zerabha zijikeleza kwi-800 ukuya kwi-1,100 RPM. Ukudibana namaphini okuphotha kunokususa iinzipho, ukwaphuka amathambo e-metacarpal, kubangele ukutshisa okukhulu okukhubekisayo, kunye nokurhuqela iimpahla endlwini. Iiclogs koomatshini benqanaba elinye ngokuqhelekileyo zenzeka xa i-slush emanzi ibambelela kwisiseko se-chute okanye xa izinto ezifana namaphephandaba okanye i-hoses yegadi ijikeleze i-rotor.

Abagibi bekhephu bamanqanaba amabini¶

Oomatshini bamanqanaba amabini yiqonga eliqhelekileyo lokucoca ikhephu elinzima lokuhlala kunye nezorhwebo. Bahlula ukuphatha ikhephu kwizigaba ezibini ezahlukeneyo zoomatshini: 1. Inqanaba lokuQala (i-Auger): Isixhobo esinye okanye ezibini esinzima, ezinabileyo zokubhabha zijikeleza kwishafti ethe tye ngesantya esicothayo noko (malunga ne-100 ukuya kwi-150 RPM). Ii-augers zisika kwimifudlana epakishiweyo, zinqumle kumaqhekeza omkhenkce, kwaye zitsalele ikhephu kumbindi wendlu. 2. Inqanaba leSibini (I-Impeller): Embindini wendlu ye-auger kuhlala i-high-speed steel impeller fan ejikeleza kwi-perpendicular axis kwi-1,000 ukuya kwi-1,200 RPM. I-auger ityisa ikhephu ngqo ebusweni balo fan, esebenzisa amandla aphakathi kunye nokunyuswa kwe-aerodynamic ukuhambisa ikhephu phezulu kwi-chute yokukhupha eya kwicala.

Ngenxa yokuba ezi nkqubo zimbini zisebenza ngesantya esahlukileyo kakhulu, inqanaba lesibini lifuna amandla amakhulu enjini kunye noxinzelelo oluphezulu lwebhanti. Oomatshini abanezigaba ezibini banoxanduva phantse kubo bonke ukunqunyulwa kwemilenze ebuhlungu ngenxa yokuba abaqhubi abafikelela ezantsi kwi-chute yokukhupha banxibelelana ne-high-speed steel impeller blades, mhlawumbi ngelixa bejikeleza okanye ngexesha lokukhululwa kwe-spring-back.

Abagibi bekhephu bamanqanaba amathathu¶

Oomatshini bamanqanaba amathathu bongeza into yesithathu yomatshini eyenzelwe ukuxinana okuphezulu, ikhephu likamasipala elinomkhenkce kunye ne-slush emanzi enzima. Ukongeza kwi-augers yokuqokelela kunye ne-impeller yokukhupha, umatshini wezigaba ezintathu udibanisa ** i-accelerator auger **. Esi santya siphezulu sokusika i-auger ephakathi ibekwe ngokude, i-perpendicular kwi-augers yokuqokelela, ijikeleza ngamaxesha angama-10 isantya sokuqokelela (malunga ne-1,000 RPM).

I-accelerator inqumla kwiidrifts ezipakishwe ngumkhenkce kwaye iqhubela ikhephu ngqo kwi-impeller blades. Abagibi bekhephu bamanqanaba amathathu banelona nqanaba liphezulu lokujikeleza kwe-inertia yaso nasiphi na isixhobo sabathengi bekhephu. Ukuba umqhubi uqhagamshelana ne-central accelerator cavity okanye i-barrel yokukhupha, isenzo esidityanisiweyo sokusika kunye nokunqunyulwa kubangela ukwenzakala okubuhlungu okutyumkileyo kunye nokunqunyulwa kweedijithi ezininzi.

Ubunjineli bonxibelelwano lokhuseleko: Ulawulo lobukho bomntu ofileyo (OPC)¶

Wonke umtshini wekhephu wale mihla owenziwe phantsi kwemigangatho yokhuseleko lwamazwe ngamazwe ubandakanya inkqubo ye-Operator Presence Control (OPC), edla ngokubizwa ngokuba yi-deadman switch okanye ibheyile yolawulo lokufa. Ezi ndlela zokhuseleko zenzelwe ukunqanda ii-augers ezijikelezayo, i-impeller, kunye ne-traction drive ukuba isebenze ngaphandle kokuba umqhubi ubamba ngokusebenzayo iilever ezilayishwe entwasahlobo ngokuchasene nezibambo zomatshini.

Ikhonkco lokufa komatshini¶

Xa umsebenzisi ecinezela i-auger control lever yebheyile ngokuchasene ne-handlebar yasekhohlo, intambo yolawulo yentsimbi ephothiweyo yodidi lwenqwelomoya itsala ingalo yepivot engasebenziyo. Esi senzo siphumeza iintshukumo ezimbini zoomatshini ngaxeshanye: 1. Uxinzelelo lwebhanti: Ipuli engasebenziyo icinezela ngokuqinileyo kwi-V-belt ye-auger drive, iyixinzelele phakathi kwepuli yokuqhuba i-injini kunye ne-auger/impeller input pulley ukuhambisa itorque yoomatshini. 2. I-Brake Shoe Retraction: Unxulumano olujikelezayo lutsalela iphedi yebrake enzima-dutyhutyhutyhutyhutytyhutytytytytytytytype ukusuka kwisangqa esingaphandle sepuli yentsimbi.

Ngelixa umqhubi ekhulula isixhasi sebheyile, imithombo enzima yokubuya itsala ipuli engasebenziyo isuke kwibhanti, iyivumele ukuba ihambe idodobala kwaye iqhawule amandla enjini. Ngaxeshanye, isicathulo sangaphakathi se-brake mechanical sinyanzeliswa ngokuchasene ne-spinning impeller pulley. Imigangatho yokhuseleko iyalela ukuba esi siqhoboshi soomatshini kufuneka izise i-impeller enesantya esiphezulu kunye neeauger ezinesantya esisezantsi ukuba zime ngxi kwimizuzwana emihlanu yokukhululwa kwebheyile.

I-interlock yombane yokucima umlilo¶

Kwizijusi zekhephu zombane ezinebhetri kwaye ukhethe oomatshini bokutsha bangaphakathi, inkqubo yokufa ibandakanya i-electromechanical interlock: - Kumatshini webhetri, ukukhulula ibheyile ngoko nangoko kuvula i-high-amperage solid-state contactor okanye i-relay, ukusika amandla e-DC kwisilawuli se-brushless motor. Ibhuleki ye-electronic evuselelayo imfutshane i-motor windings ngomthwalo ochasayo, ukumisa i-rotor ngaphantsi kwemizuzwana emibini. - Kwiiyunithi zegesi zorhwebo, ukukhulula isiseko sebheyile i-coil ye-coil wire yokuqala ngqo kwibhloko ye-injini, ukusika i-spark yombane kwi-cylinder kunye nokubulala umjikelo wokutsha ngaphandle kokuba kufakwe iswitshi ye-interlock engathathi hlangothi.

Ukuvavanya ukhuseleko lwakho lokufa: Iprothokholi yangaphambi kwexesha kunye neprotocol yangaphambili¶

Ukhuseleko oludityanisiweyo lunokwehla ngokuhamba kwexesha ngenxa yokolulwa kwentambo, ukudinwa kwentwasahlobo, ukubola kwetyuwa yendlela, kunye nokukhenkceza kwebhanti. Ikhonkco elinomkhenkce okanye elidlekileyo liya kuvumela iincakuba ukuba ziqhubeke zijikeleza nasemva kokuba umqhubi eyekile izibambo. Yenza olu vavanyo lusebenzayo ngaphambi kokucoca isaqhwithi ngasinye sasebusika:

1. UHlolo oluNgqongileyo oluBonakalayo kunye nolweCable: Xa injini icinyiwe, cinezela ibheyile yolawulo lwe-auger kwii-handlebars. Zive ngokugudileyo, ukuxhathisa okungabophiyo. Yikhulule ibheyile ngokukhawuleza; kufuneka ibuyele umva ngokuchasene nokumisa kwayo ngoomatshini ngoko nangoko ngaphandle kokuthandabuza. Jonga intambo yentsimbi ephothiweyo ecaleni kwesakhelo somatshini ukuze ubone umhlwa, ukonakala, iibhatyi zezindlu ezibotshelelweyo, okanye iijoyinti ezibophelelayo.
2. Dynamic Imizuzwana emihlanu Spin-Down Test: Hambisa umatshini kwindawo evulekileyo ngaphandle kumhlaba othe tyaba. Qinisekisa iindawo zokukhupha i-chute kude nezakhiwo kunye nabasebenzi. Qala injini kwaye usete i-throttle ukuya kwi-RPM ephezulu yokusebenza.
3. Bandakanya kwaye Ukhulule: Cinizela ibheyile ye-auger drive ukujikeleza ii-augers kunye ne-impeller. Ngelixa ujonga i-chute yokukhupha kwindawo ekhuselekileyo emva kwekhonsoli, khulula ngebheyile ngequbuliso.
4. Ixesha lokuJika ezantsi: Sebenzisa istopwotshi okanye ubale ngokuvakalayo. I-impeller kunye ne-auger blades kufuneka zime ngokupheleleyo, zingashukumi kwimizuzwana emihlanu. Ukuba i-impeller iyaqhubeka nonxweme okanye ijikeleza imizuzwana emithandathu okanye ngaphezulu, i-internal mechanical brake lining igugile, ayilungiswanga, okanye yosulelwe luthuli lwerabha yebhanti.
5. Lungisa okanye Inkonzo: Musa ukusebenzisa umatshini ongaphumeleliyo kuvavanyo lokuyeka imizuzwana emihlanu.

Imigangatho yokutshintsha isikhonkwane se-Shear kunye nee-drivetrain mechanics¶

Enye yezona mpazamo zokugcinwa rhoqo ezenziwa ngabanini bekhephu kukubuyisela ezaphukileyo izikhonkwane zokucheba ngeebholiti zehardware eziqhelekileyo. Esi senzo siyingozi sikhokelela ekutshatyalalisweni koomatshini kwintlekele, iibhokisi zegiya ezophukileyo, kunye neengozi ezinkulu zeprojekithi.

Injongo yobunjineli yezikhonkwane zokucheba¶

I-auger yangaphambili ye-snowblower yenzelwe ukucanda kwikhephu, hayi izinto eziqinileyo ezingashukumiyo. Ngelixa ucoca iindlela zokuhamba, ii-augers zihlala zidibana nemiqobo efihlakeleyo: amaqhekeza omkhenkce kamasipala, igrabile, amatye embonakalo yomhlaba, iimethi zeengcango, kunye nezinto zokudlala zabantwana ezingcwatywe phantsi kweedrifts.

Xa i-auger ibetha into engenakushukunyiswa, amandla ajikelezayo e-injini kunye ne-inertia ye-impeller yentsimbi enzima kufuneka imiswe ngoko nangoko. Ngaphandle kwefasesi yomatshini wokwenza idini, ukothuka kwempembelelo yanda ngokuthe ngqo ezantsi kweshafti ye-auger kwigiya yeentshulube zobhedu ngaphakathi kwebhokisi yegiya esembindini. Amazinyo egiya aya kuchetywa, ishafti yokuqhuba iya kugoba, okanye igearbox iya kugqabhuka, nto leyo exabisa amakhulu eedola ukuyilungisa.

Ukukhusela i-drivetrain, imikhono ye-auger yokubhabha ayidityaniswanga kwi-horizontal drive shaft. Endaweni yoko, zityibilika ngokukhululekileyo phezu kweshafti kwaye zitshixelwe kuyo kuphela ngamabini amabini okanye ngaphezulu enziwe ngobunjineli obuchanekileyo izikhonkwane zokucheba (ezikwabizwa ngokuba ziibholiti zokucheba).

Imibuzo edla ngokubuzwa¶

Kutheni i-snowblower i-impeller isahamba emva kokuba ndicime injini?¶

I-impeller iyahamba emva kokuba injini icinyiwe ngenxa yogcino loxinzelelo lomatshini kwi-drivetrain, ingozi eyaziwa ngokuba yi-impeller spring-back trap. Xa ikhephu elimanzi livala umatshini, liwela phakathi kwe-impeller blade ejikelezayo kunye nodonga lwezindlu zentsimbi, limise i-blade ngequbuliso ngelixa injini isaqhuba iipuli. Oku kolula ibhanti yerabha ye-V kwaye ijija iishafti zangaphakathi phantsi koxinzelelo olukhulu lomatshini. Xa ucima i-injini, loo xinzelelo lomatshini luhlala luvaleleke ngaphakathi kumatshini. Ukuba ufikelela ezantsi kwi-chute kwaye ukhuphe iplagi yekhephu epakishweyo, i-equilibrium ecinezelweyo iyawa, kwaye intsimbi yentsimbi ihleba ngaphambili okanye ngasemva inqumle i-20 ukuya kwi-90 degrees ngesantya sokutyumza amathambo. Ngalo lonke ixesha sebenzisa isixhobo sokucoca somthi okanye seplastiki ngaphandle kwe-chute, ungaze ube neminwe yakho.

Ndingayicima i-shute evalekileyo ngonyawo okanye ngesihlangu sam ngokukhuselekileyo ukuba andinantonga?¶

Hayi, ungaze usebenzise unyawo lwakho, isihlangu, okanye ibhutsi ukucima iclog yekhephu. Iibhotshi zibonelela ngokhuseleko lwe-zero ngokuchasene nokusikwa okujikelezayo kunye nemikhosi etyumkileyo yentsimbi ye-impeller blade. Ukuba umsebenzi ukhaba okanye utyhala ikhephu elipakishwe ngebhutsi, ukunyathela kungatyibilika kwintsimbi enomkhenkce, ilufake unyawo ngqo kwigubu le-impeller. Ngenye indlela, ukuba i-impeller ikhupha kwaye ibuyele umva, intsimbi ebukhali iya kuqhekeza ngokukhawuleza ngokusebenzisa i-rubber enzima, izikhumba eziphezulu zesikhumba, kunye neentsimbi zeenzwane zentsimbi, ezibangela ukuphuka kwe-metatarsal evulekileyo, iinzwane ezinqamlekileyo, kunye nokulimala kwe-degloving. Ukongeza, ukulinganisa ngonyawo olunye kwindlela emtyibilizi kwandisa kakhulu umngcipheko wokuwa. Ngalo lonke ixesha gcina iinyawo zombini zityalwe ngokuqinileyo kumhlaba ocoliweyo kwaye usebenzise intonga yeplanga okanye ibheyile yokucoca yasefektri ecaleni komatshini.

Kufuneka ndenze ntoni ukuba i-snowblower yam iphinda ivale iimitha ezimbalwa kwikhephu elimanzi?¶

Ukuvaleka rhoqo kubonisa ukuba ukufuma kwekhephu kugqithise umthamo womatshini okanye ukukhuhlana komphezulu wangaphakathi kuphezulu kakhulu. Okokuqala, misa umatshini, uqhawule ucingo lwe-spark plug, kwaye ucoce ngokucokisekileyo ingaphakathi le-chute kunye ne-impeller yezindlu. Tshiza intsimbi engenanto okanye iindonga zeplastiki ngesitshizi se-silicone, i-hydrophobic i-wax yemoto ye-ceramic, okanye i-non-stick spray spray, ethintela i-slush ukuba ingadibanisi phezulu. Okwesibini, hlengahlengisa ubuchule bakho bokucoca: yehlisa isantya sakho sangaphambili somhlaba ngelixa ugcina i-injini ejikelezayo kwi-RPM ephezulu, uvumela i-impeller enesantya esiphezulu ukuba yenze eyona velocity yepneumatic. Okwesithathu, thatha i-swath yokucoca encinci, usika isinye kwisithathu okanye isiqingatha sobubanzi be-auger kwi-pass nganye ukuze umatshini usebenze ubunzima obuncinci ngexesha elinye.

Kwakutheni ukuze i-auger yam iyeke ukujikeleza ngelixa i-impeller yangasemva iqhubeka nokugibisela ikhephu?¶

Ukuba i-impeller yangemva enesantya esiphezulu iyaqhubeka nokujikeleza kwaye iphosa ikhephu elikhululekileyo kodwa i-augers eqokelelweyo yangaphambili ihlala ingashukumi, enye okanye zombini izikhonkwane zakho zokucheba zikrazukile. Olu luphawu lokhuseleko lomatshini olwenzelwe ukugcina i-drivetrain yakho. Xa i-auger yokuqokelela ibetha into eqinileyo, enjengelitye, ungqameko, okanye umkhenkce, iphini elithambileyo lokucheba liqhekeka ngokucocekileyo, livumele umkhono we-auger ukuba ujikeleze ngokukhululekileyo kwishafti yawo ethe tye ngaphandle kokukhulula igiya yeentshulube zobhedu ngaphakathi kwebhokisi yegiya esembindini. Ukulungisa oku, cima i-injini, qhawula ucingo lwe-spark plug, cima wonke umkhenkce kwindlu ye-auger ngentonga, lungelelanisa imingxunya yeshafti, kwaye ufakele i-OEM yokwenyani yokucheba iphini kunye ne-locknut yayo ehambelanayo. Ungalokothi ufake indawo ye-hardware esemgangathweni yeBanga lesi-5 okanye iBanga lesi-8, njengoko intsimbi eqinile ayiyi kuphuka ngexesha le-jam yexesha elizayo, okukhokelela ekugqithiseni ukuhanjiswa.

Ndingayahlula njani phakathi kwepini yokwenyani ye-OEM yokucheba kunye nebholithi yehardware eyingozi?¶

Unokwahlula ipini yokwenyani ye-OEM yokucheba kwibholiti yentsimbi eqhelekileyo ngokuphonononga izinto ezintathu zoomatshini: i-shank, intloko yebholiti, kunye nobulukhuni bentsimbi. Okokuqala, jonga i-shank: izikhonkwane zokwenyani zokucheba zibonisa enye okanye ezimbini ezicacileyo, iigrooves ezisikwe kwintsimbi. Ezi grooves ngamanqaku oxinzelelo ngenjongo eyilelwe ukucofa ngokucocekileyo phantsi kwemithwalo ethile yokothuka. Iibholiti ze-hardware eziqhelekileyo zine-shank egudileyo, eyomeleleyo ye-cylindrical engenazo iigrooves ezisikiweyo. Okwesibini, hlola iimpawu kwintloko yebholiti: ipini yokucheba yokwenene inentloko egudileyo, engaphawulwanga okanye ibonisa uphawu oluthile lomenzi, obonisa intsimbi ethambileyo ephantsi kwekhabhoni yeBanga lesi-2. Ibholithi ye-hardware yeBanga lesi-5 ibonisa imigca emithathu ephakanyisiweyo ye-radial hash, kwaye ibholithi yeBanga lesi-8 ibonisa imigca emithandathu ye-hashi ye-radial, ebonisa intsimbi ecinyiweyo nepholileyo yokuqina kwentsimbi engasayi kwaphuka ngexesha le-auger jam. Ungaze ufake isiqhoboshelo esinophawu lwentloko yeradial okanye esingenazo iigrooves zobunjineli zokucheba.

Isiqinisekiso soncedo lokuqala¶

Ukusebenza ngokukhuselekileyo izixhobo zomatshini eziphezulu kunye nokuphendula kwi-hemorrhage eyingozi kakhulu okanye ukulimala kwemozulu ebandayo kufuna ukuqeqeshwa kwezandla. Ukubhalisa kwi-accredited aid yokuqala, i-CPR, kunye nekhosi eyisiseko yokuxhasa ubomi ngokusebenzisa i-American Red Cross, i-British Red Cross, i-St John Ambulance, i-Canadian Red Cross, okanye i-Australian Red Cross inika izakhono ezisebenzayo kwisicelo se-tourniquet, ukupakishwa kwenxeba elibuhlungu, ukulawulwa kwezicubu ezinqanyuliweyo, kunye nokuqina kwe-hypothermia. Ukuba nomncedisi wokuqala oqinisekisiweyo kwindlu yakho okanye abasebenzi borhwebo kubonelela ngokukhawuleza, ngononophelo olufanelekileyo ngelixa iinkonzo zonyango eziphuthumayo zihamba kwindawo yakho.
