I-proportional solenoid valve SV90-G39 24V isilayishi sephampu ye-hydraulic

   Ibhokisi legiya lokusabalalisa iphampu ye-CAT excavator kuwoyela we-hydraulic

(1) Iphutha elenzeka ekunakekeleni i-Carter excavator Uwoyela we-hydraulic uvaleleke ebhokisini legiya elihlukanisa iphampu futhi aphuphume kumshini wawo wokuphefumula.

(2) Ukuhlaziywa kwesizathu sokulungiswa kwe-Carter Excavator Ngenxa yokuthi amaphampu amathathu ayinhloko afakwe ebhokisini legiya elihlukanisayo lepompo, ngokusho kwesimiso sokusebenza sokuhlaziywa kwesistimu, kungase kube nezingxenye ezimbili zomzila kawoyela: enye iyibhokisi legiya elihlukanisa ipompo.
Kukhona ukungena kwamafutha we-hydraulic empompini yokugcoba, okungukuthi, ngenxa yomsebenzi wesikhathi eside, uphawu lukawoyela we-skeleton wepompo likawoyela wokugcoba lonakalisiwe noma luyaguga, okuholela ekutheni uwoyela we-hydraulic empompini eyinhloko 1 ahlasele iphampu yamafutha okugcoba futhi ukungena empompini ngokujikeleza
Ibhokisi legiya elihambayo elichichima kumshini walo wokuphefumula ngokuhamba kwesikhathi; Okwesibili ukupompa uwoyela ekuxhumekeni phakathi kwepompo eyinhloko kanye nebhokisi legiya elihlukanisayo lephampu, okungukuthi, ngenxa yokulimala noma ukuguga kophawu lwamafutha ohlaka lwephampu eyinhloko, uwoyela we-hydraulic anengcindezi ephezulu empompini oyinhloko uhlasela ngqo iphampu ehlukanisa ibhokisi legiya kanye nokuchitheka okuvela emshinini wokuphefumula. Ukudluliswa noma ukunyakaza kwe-axial kophawu lwawoyela wephampu kungabangela nokuthi uwoyela we-hydraulic uhlasele uhlelo lokuthambisa. Izizathu ziyizi: imvume yokufakwa kwe-oil seal inkulu, futhi isenzo esijikelezayo senziwa ngaphansi kokushayela kwe-pump shaft; Imigqa exhunywe kuphampuI-bearing wear phezulu ibangela ukuphuma kwe-radial ye-pump shaft, ikhubaze indandatho yangaphakathi ye-oil seal, futhi ikhulise ukucaciswa kwendandatho yangaphandle, okuholela ekudluliseni kanye nokunyakaza kwe-axial kophawu lwamafutha. Isenzo sesikhathi eside sokucindezela kwamafutha kubangela ukuthi uphawu lwamafutha luhambe nge-axially. Ukuqina kophawu lwamafutha kubangela ukuguga kobubanzi be-shaft nalo kushube, okuholela ekwandeni kokuvunyelwa okufanelekile.

(3) Ukuxazulula izinkinga zokulungisa i-Carter excavator yesondlo kuqala susa futhi uhlukanise uphawu lukawoyela lwepompo yokugcoba yebhokisi legiya elihlukanisayo lepompo, hlola ukuthi uphawu lukawoyela luhambisana kahle yini ne-shaft, nokuthi ingabe kukhona umonakalo noma ukuguga; Hlola ukuthi kukhona yini ukuguga okusobala kububanzi be-shaft yophawu lwamafutha, bese unquma ukuthi indawo enephutha yini; Bese uhlola uphawu lwamafutha ompompo oluyinhloko. Hlukanisa amaphampu angu-3 ayinhloko, susa izimpawu zamafutha futhi uhlole ukuthi imiphetho yawo yangaphakathi iyaguga noma yonakele; Ukuthi i-spring seal kawoyela iyahluleka, noma ngabe i-axial ne-radial ye-shaft ekufakweni kophawu lwamafutha inamamaki wokuguga, ukuze kunqunywe ukuthi ingabe ingxenye enephutha. Isixazululo senkinga siwukuthi: buyisela uphawu lwamafutha njalo; Hlanza njalo futhi ugcine idivayisi yokukhipha ukushisa yesistimu ye-hydraulic, futhi uhlole njalo ukucindezela kwesistimu ukuze uqinisekise ukuchithwa kokushisa okuvamile kwesistimu; Lungisa ngokufaka esikhundleni se-shaft yepompo noma ngokulungisa izingxenye ezigugile ze-radial shaft.
