Isikhungo Somkhiqizo

Izihlungi ze-hydraulic ngokuvamile zihlanganisa izihlungi zomoya, izihlungi zikawoyela nezihlungi zikaphethiloli, ezaziwa nangokuthi "izihlungi ezintathu". Isihlungi somoya sitholakala ohlelweni lokuthatha injini futhi siwukuhlanganiswa kwengxenye yesihlungi esisodwa noma ezimbalwa ezihlanza umoya. Umsebenzi wayo oyinhloko ukuhlunga ukungcola okuyingozi emoyeni okuzongena kusilinda ukuze kuncishiswe ukuguga kwangaphambi kwesikhathi kwesilinda, i-piston, iringi ye-piston, i-valve kanye nesihlalo se-valve; isihlungi sikawoyela sitholakala ohlelweni lokuthambisa injini.

Izidingo zobuchwepheshe zesihlungi se-hydraulic:

(1) Impahla ekhethekile yesihlungi kufanele ibe namandla athile okusebenza ukuze kuqinisekiswe ukuthi ngeke yonakaliswe ukucindezela kwe-hydraulic ngaphansi kwengcindezi ethile yokusebenza.

(2) Emazingeni okushisa athile okusebenza, kufanele igcine ukusebenza okuzinzile futhi iqine ngokwanele.

(3) Inekhono elihle lokunqanda ukugqwala.

(4) Isakhiwo silula ngangokunokwenzeka futhi ubukhulu buhlangene.

(5) Kulula ukuhlanza nokugcina, kulula ukufaka esikhundleni sesici sokuhlunga.

(6) Izindleko eziphansi. Isimiso sokusebenza sesihlungi se-hydraulic: uwoyela we-hydraulic ungena epayipini lesihlungi ukusuka ohlangothini lwesobunxele, ugeleza usuka entweni yesihlungi sangaphandle uye engxenyeni yangaphakathi yesihlungi, bese ugeleza uphuma lapho uphuma khona. Lapho isici sokuhlunga sangaphandle sivinjiwe, ingcindezi iyakhuphuka ukuze ifinyelele ukucindezela kokuvula kwe-valve yokuphepha, futhi amafutha angena engxenyeni yangaphakathi yesihlungi nge-valve yokuphepha, bese ephuma ephuma endaweni. Ukunemba kwe-elementi yesihlungi sangaphandle kungaphezulu kwalokho kwesihlungi sangaphakathi, futhi isici sokuhlunga esingaphakathi siyisihlungi esimahhadla.

Izizathu nezindlela zokuxazulula inkinga zento engavamile yesilinda se-hydraulic filter hydraulic zimi kanje:

1) Umoya ungena kusilinda. Idinga i-exhaust eyengeziwe noma amasilinda abamba amanzi ukuze ahambe ngokushesha nge-stroke enkulu ukuphoqa umoya ukuba uphume.

2) Iringi yokuvala yesilinda sokugcina se-hydraulic cylinder iqine kakhulu noma ixege kakhulu. Uphawu kufanele lulungiswe ukuze lunikeze uphawu olufanele ukuze kuqinisekiswe ukuthi i-piston rod ingadonselwa emuva naphambili kahle ngesandla ngaphandle kokuvuza.

3) I-coaxiality phakathi kwe-piston ne-piston rod ayilungile. kufanele ilungiswe futhi ilungiswe.

I-4) Uma isilinda se-hydraulic singahambisani nesitimela somhlahlandlela ngemva kokufakwa, sidinga ukulungiswa noma ukufakwa kabusha ngesikhathi.

Lapho i-piston rod igobile, induku ye-piston kufanele ilungiswe.
