Impompo yepetroli idlala indima engenakuphinda ithathelwe indawo ekusebenzeni kwenjini.Ke ukuba i-petroli yepompo yoxinzelelo lweoyile ayinelanga, zeziphi iimpawu eziya kubonakala?Ingakanani i-oyile yepompo yepetroli yoxinzelelo oluqhelekileyo?
Iimpawu zokungonelanga koxinzelelo lweoyile yepompo yepompo yepetroli
Ukuba uxinzelelo lwamafutha epompo yepetroli ayanelanga, ezi mpawu zilandelayo ziya kuvela:
I-1, Xa isithuthi siqhuba, ipompo yepetroli yenza "i-buzzing" ingxolo phantsi kwesihlalo esingasemva.
I-2, Ukukhawuleza kwesithuthi sibuthathaka, ngakumbi xa sihamba ngokukhawuleza, siya kuziva sididekile.
3, Xa uqalisa isithuthi, kunzima ukuqalisa isithuthi.
4, Impazamo yokukhanya kwe-injini kwiqela lesixhobo ihlala ivuliwe.
Lungakanani uxinzelelo lwempompo yepetroli eqhelekileyo?
Xa i-ignition switch ivuliwe kwaye injini ingaqaliswanga, uxinzelelo lwamafutha kufuneka lube malunga ne-0.3MPa;xa i-injini iqaliswa kwaye injini ingasebenzi, uxinzelelo lwepetroli lwempompo yepetroli kufuneka lube malunga ne-0.25MPa.
Umsebenzi kunye nomgaqo wokusebenza wempompo yepetroli yoxinzelelo oluphezulu
I-oyile yokukhupha ipompo ye-oyile yoxinzelelo oluphezulu ingena kwi-oyile epholileyo.Emva kokuba i-oyile epholileyo iphumile, ingena kwisihluzo se-oyile.Emva kokuphuma kwi-oyile yokucoca, kukho iindlela ezimbini.Enye kukubonelela nge-oyile yokuthambisa emva koxinzelelo, kwaye enye yioyile yokulawula.Kusenokubakho i-accumulators enye okanye ezimbini kwisekethe yeoli.
Umsebenzi wayo kukuphucula uxinzelelo lwe-fuel, i-injection ephezulu yokufumana i-atomization effect, i-high-pressure oil pump isetyenziswa kakhulu njengomthombo wamandla wezixhobo ze-hydraulic ezifana neJack, umatshini ophazamisayo, i-extruder, umatshini we-jacquard, njl.
Ipompo yeoyile yoxinzelelo oluphezulu lunxibelelwano phakathi kwesekethe yeoli yoxinzelelo oluphezulu kunye noxinzelelo oluphantsi lwesekethe yeoli.Umsebenzi wayo kukuvelisa uxinzelelo lwamafutha kumbhobho kaloliwe oqhelekileyo ngokulawula ukuphuma kwamafutha.Phantsi kwazo zonke iimeko zokusebenza, ikakhulu inoxanduva lokubonelela ngesibaso soxinzelelo oluphezulu olwaneleyo kuloliwe oqhelekileyo.
Impompo yeoli yoxinzelelo oluphezulu isetyenziswa ikakhulu njengomthombo wamandla wezixhobo zehydraulic ezifana neJack, umatshini ophazamisayo, umatshini okhuphayo kunye nomatshini wejacquard.Ulandelelwano lofakelo lwempompo ye-oyile ephezulu ngolu hlobo lulandelayo: ngexesha lokufakwa kwempompo yeoli ye-high-pressure, ukwenzela ukuthintela imicimbi yangaphandle ukuba ingangeni kumatshini, zonke izimbobo zeyunithi ziya kugqunywa.Iyunithi ibekwe kwisiseko kunye neebholiti ze-anchor ezifakwe ngaphakathi, kwaye iperi ye-wedge pads isetyenziselwa ukulinganisa phakathi kwesiseko kunye nesiseko.Ubunzulu beshafti yempompo kunye ne-motor shaft iya kulungiswa.Ukutenxa okuvumelekileyo kwisangqa sangaphandle sendlela yokudibanisa kuya kuba yi-0.1 mm;Ukukhutshwa phakathi kweenqwelo ezimbini zokudibanisa kuya kuqinisekiswa ukuba yi-2-4 mm (ixabiso elincinci lempompo encinci) liya kuba yinto efanayo, kwaye ukuphambuka okuvumelekileyo kuya kuba ngu-0.3 mm.
