Chalk chojambulira Chalk chozungulira valavu 410127-00095 hydraulic valve

Kukonza zofukula za Cummins injini ya dizilo, 1. Chosinthira choyambira chikatembenuzidwira pamalo otsekedwa, koyilo ya solenoid ya valavu yoyimitsa solenoid imatayika pakali pano, kuyamwa kumasowa, ndipo mbale ya valve ya stop solenoid valve imatseka kuzungulira kwamafuta pansi pa kukankhira kwa mbale ya masika, kuti injini yazimitsidwa. Ngati valavu ya solenoid siyikutsekedwa mwamphamvu, idzapitirizabe kupereka mafuta kumalo opangira mafuta, kotero kuti kuthamanga kwa mafuta kutsogolo kwa dzenje la jekeseni la jekeseni sikungathe kuchepetsedwa panthawi yake ku mphamvu ya mafuta amoto, zomwe zimapangitsa kuti pakhale zovuta. Ngati valavu ya solenoid sichitsekedwa mwamphamvu, kutalika kwa nthawi yozimitsa kumakhala kosiyana, komwe kumatha kufika masekondi makumi angapo mpaka mphindi zingapo.
Mafuta ojambulira zitsulo zachitsulo choyang'ana mpando wa valve siwolimba, chisindikizo sichimangika pamene jekeseni wa zitsulo zachitsulo choyang'ana mpando wa valve siwolimba, chisindikizo sichili cholimba, valavu yoyang'ana mpira wachitsulo sichimatsegula, zomwe zimapangitsa kuwonjezeka kwa kuthamanga kwa mafuta. kutsogolo kwa jekeseni wa metering dzenje, zomwe zimapangitsa kuti moto ukhale wovuta. Cholakwika ichi ndi chosiyana ndi zolakwika zitatu zomwe tatchulazi, pamene valavu yoyang'ana mpira wachitsulo ya jekeseni ya cylinder sichikhazikika ndipo sichitsekedwa mwamphamvu, kuthamanga kwa mafuta kokha kutsogolo kwa dzenje la metering la jekeseni wa silinda kumakhudzidwa, ndi zina -ma silinda olakwika samakhudzidwa. Ngati 1 yokha ya 6 jekeseni ikulephera, silinda imodzi yokha ikugwira ntchito pamene kuli kovuta kuzimitsa; Ngati majekeseni awiri alephera, ma silinda awiri amagwira ntchito, ndi zina zotero. Chifukwa cholakwacho ndi cha munthu payekha, chikhoza kufufuzidwa ndi "njira yosweka ya silinda" poyang'anitsitsa, kapena kuwona kuti silinda iti ikugwira ntchito mutachotsa chitoliro chotulutsa mpweya. Komabe, PT mafuta dongosolo si yosavuta kugwiritsa ntchito "yamphamvu break njira" monga Bosh mafuta dongosolo. Malinga ndi zomwe wolemba zinachitikira, chida angagwiritsidwe ntchito kukweza jekeseni plunger galimoto rocker mkono mwamphamvu, kotero kuti wakhala mbamuikha pa mafuta chikho, plunger sangathe kusuntha, kotero kuti sangathe kuyeza mafuta, sangathe kubayidwa kuti akwaniritse cholinga chothyola silinda.
