I-Excavator Loader Main Gun Ukusiza I-Valve 708-1w-04850

Njenge-valve yokulayisha njengomlawuli wengcindezi ekude:

I-valve ye-Multistage ephakeme futhi ephansi isetshenziswa njenge-valve yokulandelana ukuze ukhiqize ingcindezi ye-Back (intambo kwisifunda samafutha esibuyayo).

I-Pilot Supply Valve iqukethe izingxenye ezimbili: i-valve eyinhloko ne-valve yokushayela. Ama-Pilot Valves afana nama-valves wokusiza aqonde ngqo, kepha ngokuvamile anezikhonkwane (noma i-ball valve) izinhlaka zezihlalo ezenziwe ngesandla. I-valve eyinhloko ingahlukaniswa ibe yisakhiwo esisodwa esigxilisiwe, isakhiwo ezimbili ezigxilile kanye nesakhiwo ezintathu ezigxilile.

Ngemuva kwe-PC200-6 ngokugcwele i-hydraulic embiwe, idivaysi esebenzayo ingabona izenzo ezahlukahlukene, kepha ipompo enkulu ithumela umsindo ongajwayelekile.

Ngokusho kokuhlaziywa kokuqala, kukholelwa ukuthi iphampu liyacishwa noma umjikelezo kawoyela uxutshwe nomoya. Ngakho-ke, qala ulungise idivaysi esebenzayo endaweni yokutholwa kwamafutha, bese ubheka ukuthi izinga lamafutha ethangi le-hydraulic lingaphansi kwezinga eliphansi lethagethi kawoyela, okuyisikhundla sokushoda kwamafutha. Ngemuva kokubuza umshayeli, indandatho yokubopha inkanuko yepayipi eliphakeme kakhulu eliholela egumbini elingenamsoco yebhakede lesilinda sebhakede lathathelwa indawo ngenxa yokuvuza kawoyela ngesikhathi somsebenzi, kepha izinga lamafutha alizange lihlolwe ngesikhathi ngemuva kokubuyiselwa emuva. Ngakho-ke, okokuqala, ithangi likawoyela le-hydraulic livuselelwa ezingeni elijwayelekile kawoyela, futhi ukuhlolwa kukhombisa ukuthi umsindo ongejwayelekile uncishisiwe, kodwa kusekhona; Ngemuva kwalokho, nge-main pump excop eff valve kumpompo enkulu ngemuva kokuhlolwa kabusha, kutholakala ukuthi umsindo ongejwayelekile usekhona, okukhombisa ukuthi umsindo awubangelwa ngokuphelele yi-Pumps Suction.

Okulandelayo, isihlungi se-oyili yokucwilisa kanye nesihlungi sokubuyiselwa kwamafutha sethangi le-hydraulic kuhloliwe, futhi kutholakala ukuthi isihlungi sokucwilisa kawoyela simnyama futhi kukhona izinhlayiya zamafutha, futhi izinhlayiya zensimbi ezinsundu zinamathele esihlungi sokubuyisa uwoyela. Uma kucatshangelwa ukuthi kunezinhlayiya zensimbi ezinsundu ezinamathele ekuhlungelweni kwamafutha okubuyisayo, kukhishwa uwoyela wepompo enkulu futhi ahlolwe, futhi kutholakala ukuthi kukhona nezinhlayiya zensimbi ezinsundu; Ngasikhathi sinye, lapho iphampu enkulu yahlakazeka futhi yahlolwa, kwatholakala ukuthi ipiston, ipuleti le-valve nepuleti lalilinyazwa, kanti isicucu esipelayo sasilinyazwa. Ngemuva kokubuyiselwa kwayo, umhlangano wenziwa ngokuqinile nezidingo, uhlelo lwe-hydraulic lwahlanzwa futhi uwoyela waguqulwa, kwathi lapho umshini wokuhlola usuqaliwe futhi, kwaphela umsindo wokuhlola.

Ngaphansi kwezimo ezijwayelekile, izimbangela zomsindo ongajwayelekile ezizungeze iphampu enkulu zingokulandelayo:

Amafutha e-hydraulic anganele abangela ukuthi ipompo enkulu ingenalutho; Umoya uxutshwe umugqa wokumunca; I-Suction Filter Block iholela ekutholeni kokumunca kwephampu; Ukugqokwa kwangaphakathi kwephampu enkulu kubangela umsindo ongafanele ekusebenzeni kwephampu enkulu.

Kulokhu, umsindo ongajwayelekile ubangelwa uwoyela onganele we-hydraulic kanye nokugqokwa kwe-slipper ngaphakathi kwephampu enkulu. Isizathu ukuthi izinga lamafutha alibhekwanga ngesikhathi ngemuva kokufakwa esikhundleni se-seal, okuholela kumafutha anganele e-hydraulic, ukuze iphampu enkulu likhiqize into ethile; Lapho uwoyela oxutshwe nomoya ugeleza ephampu enkuluji, i-slipper ayikwazi ukuntanta noma ukuntanta ngezikhathi ezithile, okuholela ekwakhekeni kwepuleti lamafutha okugcoba phakathi kokusebenza kweplanethi
