Umgangatho oPhezulu weDizili yokuTofa iPump Plunger 9 411 085 006 9085-006 iiNdawo zeNjini 9411085006

Iperi yeplunger kwi-injini ye-diesel yinxalenye enokutyiwa. Ukuba ithe yatshintshwa ngokuthanda kwayo ngexesha lokugcinwa kwesethi ye-diesel generator, ngokuqinisekileyo iya kubangela inkunkuma. Ngoko ke, kubalulekile ukulawula indlela yayo yokuchonga.

Ngokolungiselelo lwe-plunger, impompo ye-plunger inokwahlulwa ibe yimpompo ye-radial plunger kunye ne-axial plunger pump. I-axis ye-plunger yepompo ye-axial plunger ihambelana ne-axis ye-drive shaft, ngelixa i-axis ye-plunger yepompo ye-radial plunger i-perpendicular kwi-axis ye-drive shaft. Kungakhathaliseki ukuba yiyiphi ifom, umgaqo osisiseko uyafana.

Umsebenzi weperi ye-plunger yepompo yokutofa kwe-injini ye-diesel kukunyusa uxinzelelo lwe-diesel ukuhlangabezana neemfuno zoxinzelelo lwe-injection yombhobho we-injector kunye nokulawula umthamo we-oyile kunye nexesha lokunikezelwa kwepetroli. Isibini seplunger siyinxalenye ebalulekileyo kwindibano yempompo yokutofa. Akufunekanga ibe nokutywinwa okulungileyo kuphela, kodwa kunye neempawu ezintle zokutyibilika. Ukuba i-plunger ibambekile okanye ibambekile, iya kwenza ukuba i-rack ibe nzima ukuyihambisa, okanye ingakwazi ukuhamba, kwaye umlungisi uya kusilela.

Umonakalo wesibini seplunger unxitywa ikakhulu, kwaye iindawo zokunxiba zigxininiswe kakhulu kwindawo yokusebenza yendawo, oko kukuthi, iindawo ezihambelanayo zentloko yeplunger kunye nomngxuma we-oyile yomkhono we-plunger, umda we-groove stop supply kunye udini lomngxuma weoyile yokubuya. Iindlela zokuhlola kunye nokuchonga zezi zilandelayo:

(1) Ukuhlolwa kwemoto.

① Indlela yokuhlalutya iimpazamo. Ukunxitywa kweperi yeplunger kunempembelelo enkulu kwi-engile yonikezelo lwamafutha kwangaphambili. Xa impompo yokutofa kwepetroli iqala ukubonelela ngamafutha emva kwexesha, ixesha lonikezelo lwepetroli liphela kwangoko, kwaye uxinzelelo lonikezelo lwamafutha alwanelanga, misa imoto kwaye ukrazule i-crankshaft ukumamela isandi sokutofa kwamafutha. Ukuba awusiva isandi sesiqhelo sokutofa ngamafutha, oko kuthetha ukuba iperi yeplunger igugile kwaye kufuneka itshintshwe.

② Indlela yokuva umnwe phezulu. Susa umbhobho we-oyile woxinzelelo oluphezulu, beka i-throttle kwindawo yonikezelo lwe-oyile ephezulu, cinezela ubhontsi ngamandla emlonyeni wombhobho we-oyile yokuphuma kwe-oyile, uze ukrazule i-crankshaft ukwenza i-oyile yempompo ye-oyile okanye usebenzise i-screwdriver ukucofa i-oyile. unyawo lokumpompa. Ukuba uxinzelelo lweoyile luphezulu kakhulu kwaye isithupha sinzima ukusicinezela, kuthetha ukuba i-plunger pair ingaqhubeka isetyenziswa; ukuba uxinzelelo lweoyile lubuthathaka, oko kuthetha ukuba iperi yeplunger inxibe kakhulu kwaye kufuneka itshintshwe.

(2) Indlela yokuvavanya i-injector. Xa ujonga iperi ye-plunger ye-cylinder, susa umbhobho we-oyile woxinzelelo oluphezulu kwaye uyiguqule kwenye i-angle, udibanise i-injector esemgangathweni (uxinzelelo olulungelelanisiweyo ukuya kwi-19.6 MPa), yenza i-nozzle ye-injector ijonge phantsi, lungisa i-throttle kwindawo ephezulu yokunikezelwa kwamafutha. isikhundla, kunye nokukrazula i-crankshaft emva koxinzelelo ukujonga imeko ye-atomization yesitofu. Ukuba i-atomization ilungile, ibonisa ukuba i-plunger pair ingaqhubeka isetyenziswa; ukuba i-injector ayitshizi ioli, ibonisa ukuba i-plunger pair igugile kwaye i-oyile yepompo ibuthathaka, kwaye ayinakusetyenziswa.

(3) Indlela yokulinganisa isixhobo. Sebenzisa igeyiji yoxinzelelo enoluhlu lwe-0-60 MPa, uyiqhagamshele kumbhobho we-oyile woxinzelelo oluphezulu wempompo yokutofa isilinda, beka i-throttle kwindawo ephezulu yokubonelela ngamafutha, kraqa i-crankshaft ukucima umoya, kwaye uvumele igeji. ukunyuka koxinzelelo kwi-24.5 MPa. Qwalasela isantya sokuhla koxinzelelo lweoyile kwigeyiji yoxinzelelo. Ngokuqhelekileyo, kufuneka ihla kwi-24.5 MPa ukuya kwi-14.7 MPa engekho ngaphantsi kwemizuzu ye-5-10 ukuba ilungile.

(4) Indlela yokujonga. Sebenzisa iliso okanye i-4-10x yeglasi yokukhulisa ukujonga ukuba ngaba kukho iimpawu ezicacileyo zokuguga, i-grooves, okanye amabala e-rust kumphezulu we-plunger, nokuba imiphetho ye-oblique grooves kunye ne-grooves ethe tye entloko ye-plunger. zibuthuntu okanye zixotyulwe, kwaye nokuba iplunger ineziphene ezifana nokugoba okanye ukuguqulwa kwentloko.
