Excavator loader main gun relief valve 708-1W-04850

Sevharuvhu yekuburitsa seremote pressure regulator:

A high and low pressure multistage control valve inoshandiswa sevhavha yekutevedzana kuti ibudise kumashure kumanikidzika (tambo pakudzoka kwemafuta rekiti).

Ivhavha yekuyamura mutyairi ine zvikamu zviviri: vharuvhu hombe uye vharafu yekutyaira. Mavharuvhu ekutyaira akafanana neakananga-anoita mavharuvhu ekuyamura, asi anowanzo ari cone vharafu (kana bhora vharafu) akaumbwa zvigaro zvimiro. Ivhavha huru inogona kukamurwa kuva imwe concentric chimiro, maviri concentric chimiro uye matatu concentric chimiro.

Mushure mekunge PC200-6 yakazara hydraulic excavator yatangwa, chishandiso chinoshanda chinogona kuona zviito zvakasiyana, asi pombi huru inotumira ruzha rusina kujairika.

Maererano nekuongorora kwekutanga, zvinotendwa kuti pombi inovharwa kana kuti dunhu remafuta rinosanganiswa nemhepo. Nokudaro, tanga wagadzirisa chigadziro chekushanda kune nzvimbo yekuona chiyero chemafuta, uye chengetedza kuti chiyero chemafuta che hydraulic tank chiri pazasi pezinga rakaderera rechinangwa chemafuta, iyo ndiyo nzvimbo yekushayikwa kwemafuta. Mushure mokubvunza mutyairi, mhete yekuisa chisimbiso yepombi yemafuta yepamusoro-soro inotungamira kukamuri isina tsvimbo yebhakiti rodhi cylinder yakatsiviwa nekuda kwekubuda kwemafuta panguva yebasa, asi mwero wemafuta hauna kuongororwa munguva mushure mekutsiviwa. Naizvozvo, chekutanga, iyo hydraulic mafuta tank inowedzerwa kune yakajairika mafuta level, uye bvunzo inoratidza kuti ruzha rusina kujairika rwakaderedzwa, asi richiripo; Zvadaro, kuburikidza nevhavha huru yepombi yepombi kune pombi huru mushure mekuedzwa zvakare, inowanikwa kuti ruzha rusina kujairika ruchiripo, zvichiratidza kuti ruzha harungagoni kukonzerwa zvachose nekusveta kwepombi.

Tevere, iyo yekusveta mafuta sefa uye mafuta ekudzosa sefa ye hydraulic tank inotariswa, uye inowanikwa kuti mafuta ekusveta sefa yakasviba uye kune madhaka emafuta, uye simbi yebrown inonamira pamafuta ekudzosa sefa. Tichifunga nezvekuti kune mabrown metal particles akanamatira pafiriji yemafuta ekudzoka, mafuta epombi huru anosunungurwa uye anoongororwa, uye anowanikwa kuti kunewo zvidimbu zvesimbi zvakasvibirira; Panguva imwecheteyo, apo pombi huru yakaparadzaniswa uye yakaongororwa, yakawanikwa kuti piston, ndiro yevhavha uye ndiro yekutsvaira yakanga isina kukuvara, uye slipper shoe yakasakara. Mushure mekutsiviwa kwayo, gungano rakaitwa zvakanyatsoenderana nezvinodiwa, iyo hydraulic system yakacheneswa uye mafuta akashandurwa, uye apo muchina wekuyedza wakatangwa zvakare, ruzha rusina kujairika rwakanyangarika uye kukanganisa kwakabviswa.

Mumamiriro ezvinhu akajairwa, zvikonzero zvinogona kukonzera ruzha rwakatenderedza pombi huru ndezvizvi:

Kusakwana hydraulic mafuta kunoita kuti pombi huru ipere; Mhepo inosanganiswa mumutsetse wekusveta; Suction filter block inotungamira kune hombe yekusveta pombi; Kupfeka kwemukati kwepombi huru kunokonzera ruzha rusina kujairika mukushanda kwepombi huru.

Muchiitiko ichi, ruzha rusina kujairika rwunokonzerwa nekusakwana hydraulic mafuta uye kupfeka kweinotsvedza mukati mepombi huru. Chikonzero ndechekuti mafuta emafuta haatariswe munguva mushure mekutsiviwa kwechisimbiso, zvichiita kuti pave nemafuta asina kukwana e hydraulic, kuitira kuti pombi huru ibudise suction phenomenon; Kana oiri yakasanganiswa nemhepo ichiyerera nepapombi huru, inotsvedza haigone kuyangarara kana kuyangarara zvisina kukwana mune dzimwe nguva, zvichikonzera kuumbwa kwefirimu remafuta ekuzora rakanaka pakati peinotsvedza neplate yekugezesa, izvo zvinoita kuti inotsvedza ipfeke uye pakupedzisira ikonzerese. ruzha rusina kujairika mukushanda kwepombi huru
