I-Excavator loader main gun relief valve 723-40-94501

Iningi labavubukuli linamaphampu amabili amakhulu, ngakho-ke i-valve enkulu yokusiza inamabili (owaziwa nangokuthi i-valve yokuphepha eyinhloko), ngokulandelanayo lawula iphampu eyinhloko, bese iphampu ngayinye ilawula izenzo ezi-3, ibhakede kanye nengalo enkulu yokuhamba nohlangothi olulodwa. iyiqembu, ingalo ephakathi, ukuzungezisa kanye nokungaphandle kokuhamba okuseceleni kuyiqembu, wonke amavalvu okusiza amabili amakhulu (amavalvu okusiza umshayeli) alawula izenzo ezintathu eziphambene.

Futhi ekugcineni banamavalvu abo okusiza isenzo ngasinye, njengengalo ephakamisayo kanye nengalo eyehlisayo enamavalvu awo okusiza. I-valve yokusiza eyinhloko ilawula ngokuyinhloko ukucindezelwa kwamaphampu amabili amakhulu, ngakho-ke ukucindezela kwezenzo ezintathu ezilawulwa yipompo eyinhloko kuyafana, ngokuvumelana nezidingo, uma ukucindezela kwesenzo esisodwa kunganele noma kuphezulu kakhulu, khona-ke i-valve yokusiza ehlukile yesenzo ingalungiswa.

Ku-valve eyinhloko, kunomehluko ocacile kwamanye ama-valve okusiza. I-valve yokusiza eyinhloko ye-excavator enomsebenzi wokuqinisa izoba nepayipi lokushayela elingaphezu kweyodwa. Inkinga ye-valve yokusiza eyinhloko ngokuvamile ukuthi intwasahlobo yangaphakathi iphukile noma ihlulekile, i-valve core igugile, futhi wonke umsebenzi ubuthakathaka futhi ingcindezi ayikwazi ukusungulwa.

Ngemuva kokuthi i-PC200-6 i-excavator egcwele amanzi amaningi iqalisiwe, idivayisi esebenzayo ingabona izenzo ezihlukahlukene, kodwa iphampu enkulu ithumela umsindo ongajwayelekile.

Ngokusho kokuhlaziywa kokuqala, kukholakala ukuthi iphampu ine-vacuumed noma umjikelezo kawoyela uxutshwe nomoya. Ngakho-ke, qala ngokulungisa idivayisi esebenzayo endaweni yokuthola izinga likawoyela, futhi uhlole ukuthi izinga likawoyela lethangi le-hydraulic lingaphansi kwezinga eliphansi lethagethi kawoyela, okuyisimo sokushoda kukawoyela. Ngemva kokubuza umshayeli, indandatho yokuvala yepayipi likawoyela elinomfutho ophezulu oholela ekamelweni elingenazintambo le-cylinder yenduku yebhakede yashintshwa ngenxa yokuvuza kwamafutha ngesikhathi somsebenzi, kodwa izinga likawoyela alizange lihlolwe ngesikhathi ngemva kokushintshwa. Ngakho-ke, okokuqala, ithangi likawoyela we-hydraulic lifakwa ezingeni likawoyela elijwayelekile, futhi ukuhlolwa kubonisa ukuthi umsindo ongavamile uyancipha, kodwa usekhona; Khona-ke, nge-valve yokukhipha ipompo eyinhloko eya empompini enkulu ngemva kokuhlolwa kabusha, kutholakala ukuthi umsindo ongajwayelekile usekhona, okubonisa ukuthi umsindo awukwazi ukubangelwa ngokuphelele ukumuncwa kwepompo.
