Piston iqembu: imishini futhi ama-apharathasi

Piston iqembu - iqembu piston uphawu izindandatho. Njengoba nje sifaka pin piston nemininingwane obandayo. It kuyafaneleka ukucabangela ukuqokwa indlela.

Ngenxa yakhe waqonda igesi ingcindezi futhi idluliselwa ngokusebenzisa induku yokuxhuma crankshaft. Vele ngenxa lamasu, njengoba iqembu piston, isikhala isilinda ngaphezu piston selinqunyiwe. Ngakho-ke kuyokwenziwa bavikelekile contact ngokweqile nge crankcase lubricating amafutha bese kuthi amagesi. Lesi sici Kumqoka kakhulu ekusebenzeni kahle injini. Mayelana ukuthi, kulokho isimo lobuchwepheshe, ahlulelwe yibo ikhono uphawu. Ngokwesibonelo, e-injini yemoto ayivunyelwe uwoyela ukusetshenziswa Imali ilinganiselwa ngaphezulu kuka ezintathu angu ukusetshenziswa kukawoyela.

Piston iqembu lucwaningo umsebenzi walo ngisho ezindaweni nokhahlo. Yingakho imininingwane yaleli indlela babe high amandla ezishisayo, futhi lokhu kunakwe lapho impahla kanye nomklamo abakhethiwe ngabo. Lezo zinto ngokuvamile abakhiqizi design, unikezwa uhlobo injini kanye uya khona (ezokuthutha, umile, idizili, ifomu, njll). Nokho, uhlaka namanje uhlala okufanayo. Ngakho, kufanele ucabangele, yini piston iqembu.

Wendlovu piston ingxenye (umhlahlandlela) ubizwa nangokuthi umphetho piston. Kuyinto ngaphakathi namagagasi, babhola imigodi piston pin. Unqenqema engezansi umphetho livame ukusetshenziswa njengendlela base kwezobuchwepheshe ukwelapha piston. Kungenxa yalesi collar unikezwa kwathela. Ngaphezu kwalokho, isiketi izindonga namanje ukuqonda amandla yokucindezelwa lateral, futhi kwandisa ukuhilizisana kwabo emdulini isilinda futhi kukhulisa Ukushisa uMbhalo bese piston.

Inhloko piston ithwala piston izindandatho has a phansi. I inkatho aphansi has a imbobo amanzi ngokusebenzisa ezisabalele amafutha lubricating ukuze kayiwanga ngephutha ekamelweni amandla omlilo. phansi kwakhe - lokhu ingenye izindonga ekamelweni. Kuthatha eside ingcindezi amagesi. kakhulu Phansi kungaba flat, phakathi, convex noma okwenyanga. Nalapha futhi, injalo kuyakhethwa lapho uhlobo injini bhalisiwe, futhi egumbini amandla omlilo.

Akunakwenzeka ukuba sikusho indlela ezifana isilinda-piston iqembu. I ukukhubazeka eyinhloko block isilinda - odabukileyo, aqhephukile futhi ukugqoka. Lezi amaphutha amiswa emva ukuhlolwa olunzulu, ingcindezi ukuhlolwa kanye nesilinganiso isilinda. Kule nqubo, block ufuna ukufaka ikhanda noma sensimbi ipuleti (oyisibopho iraba gasket). Ngokuvamile, leli qembu kuyahluka ukushisa ukumelana steel namafutha Ukupholisa, okuyinto kwenziwa ngezithukuthuku jikelele kwegazi uhlelo Lubrication main udizili. Uma unikeza ezinhle indlela ukunakekelwa namafutha eliphezulu, kungenzeka ukwandisa kalula empilweni lo pistons futhi amasilinda.

Futhi nangenye indlela - the yokuxhuma induku piston iqembu. I piston - bese waphonsa aluminium. Ebusweni elingaphandle has simise oyinkimbinkimbi kakhulu. Piston pin - nomgodi ezenziwe ngensimbi, kuba mahhala ukujikisa emkhonweni we yokuxhuma induku piston abaphathi. A piston ring ezenziwe cast iron. Futhi-ke, induku - nensimbi kokuzihlanganisa. Esikhathini ikhanda engenhla has a emikhonweni wawenziwa ngengxube ye steel neyethusi, okuyinto kunomphumela omuhle lonke iqembu.
