Umsebenzi kunye noLondolozo lwe-injini ye-Diesel Crankcase uMbhobho wokuphefumla
2021-07-29
Iinjini zedizili zixhotyiswe ngemibhobho ye-crankcase yokuphefumla, eyaziwa ngokuba zii-respirators okanye ii-vents, ezinokwenza i-cavity ye-crankcase inxibelelane nomoya, ukunciphisa ukusetyenziswa kwamafutha, ukunciphisa ukusilela, kunye nokuqinisekisa ukusebenza kakuhle kokusebenza. Xa i-injini isebenza, irhasi ekwisilinda ngokuqinisekileyo iya kuvuza kwi-crankcase, kwaye ukuvuza kwe-cylinder liner, ipiston, i-piston ring kunye nezinye iindawo kuya kuba nzima ngakumbi emva kokugqoka. Emva kokuba irhasi ivuza kwi crankcase, uxinzelelo lwerhasi ekwikhrankcase luya kwanda, lubangele ukuba i-oyile ivuze kumphezulu odibeneyo womzimba we-injini kunye nepani yeoli kunye nomngxuma we-oyile yegeyiji. Ukongezelela, igesi evuzayo iqulethe i-sulfur dioxide, kwaye ubushushu buphezulu, nto leyo eya kukhawulezisa ukuwohloka kweoli ye-injini. Ngokukodwa kwi-injini ye-cylinder enye, xa i-piston ihla, igesi kwi-crankcase ixinzelelwe, ebangela ukuchasana nokuhamba kwepiston.

Ngoko ke, umsebenzi wombhobho wokuphefumla we-crankcase unokushwankathelwa ngolu hlobo: ukuthintela ukuwohloka kweoli ye-injini; ukuthintela ukuvuza kwe-oyile ye-crankshaft kunye ne-crankcase gasket; thintela amalungu omzimba ukuba angonakaliswe; thintela imiphunga yeoli eyahlukahlukeneyo ekungcoliseni umoya. Ekusetyenzisweni kwangempela, akunakuphepheka ukuba umbhobho wokungenisa umoya uya kuvinjelwa. Ukuyigcina ingavalwanga, kufuneka kwenziwe umsebenzi wokulungisa rhoqo. Kwimeko-bume yokusebenza ngokubanzi, yonke i-100h ingaba ngumjikelo wokulondoloza; ukusebenza kwindawo enzima enothuli oluninzi emoyeni, umjikelezo wokulondoloza kufuneka ube ngu-8-10h.

Iindlela ezithile zokuwugcina zezi zilandelayo: (1) Qwalasela umbhobho ukuba umcaba, umonakalo, ukuvuza, njl. njl., uze uwucoce uze uwuvuthele ngomoya ocinezelweyo. (2) Kwisixhobo sokungenisa umoya secrankcase esinevalve yendlela enye, kuyimfuneko ukuba kugxininiswe ekuhlolweni. Ukuba ivalve yendlela enye ibambekile kwaye ayivulwanga okanye ivalekile, umoya oqhelekileyo we-crankcase awunakuqinisekiswa kwaye kufuneka ucocwe. (3) Khangela ivacuum yesivalo. Khulula ivalve yendlela enye kwi-injini, emva koko uqhagamshele ithumbu lokungenisa umoya, kwaye usebenzise i-injini ngesantya esingasebenziyo. Beka umnwe wakho ekupheleni kwevalve yendlela enye. Ngeli xesha, umnwe wakho kufuneka uve i-vacuum. Ukuba uphakamisa umnwe wakho, izibuko levalvu kufuneka libe nesandi sokufunxa esithi "Pop "Pap"; ukuba akukho mvakalelo yokufunxa okanye ingxolo kwiminwe yakho, kufuneka ucoce ivalve yendlela enye kunye nombhobho wokuphuma.
