Excavator hydraulic pombi yemafuta yekupa haina kukwana, kudzvanywa hakugone kusimuka kuita sei?

Iyo hydraulic pombi ndiyo mudziyo wesimba weiyo excavator hydraulic system, inoshandura iyo mechanic simba remota kuita hydraulic simba uye inobuda kuyerera nekumanikidza, uye inogara yakakosha chinzvimbo muhydraulic system. Kana iyo hydraulic pombi ikatadza, ichakanganisa basa rakajairwa reiyo yese hydraulic system. Ichi chinyorwa chinonyanya kusuma iyo yekuchera hydraulic pombi kutadza kukonzeresa uye nzira dzekugadzirisa matambudziko.

Pressure haikwire

Chikonzero 1: pombi haisi pamafuta kana kusakwana kuyerera.

Mushonga: zadza pombi nemafuta anoshanda.

Chikonzero chechipiri: reyero valve kugadzirisa kudzvinyirira kwakaderera kana kutadza.

Mushonga: Gadzirisa zvakare kudzvanywa kwevhavha yekuyamura kana kugadzirisa vharafu yekuyamura.

Chikonzero chechitatu: Kudonha muhurongwa.

Mushonga: Tarisa sisitimu, gadzirisa nzvimbo yekudonha.

Chikonzero chechina: Iyo pombi yekuvhara screws yakasunungurwa nekuda kwekudengenyeka kwepombi yemafuta inoshanda kwenguva yakareba.

Mushonga: Simbisa masiruuru zvakanaka.

Chikonzero chechishanu: Kudonha kwemhepo mupombi yekudhonza.

Nzira yekubvisa: tarisa zvinongedzo, uye sunga chisimbiso nekusimbiswa.

Chikonzero chechitanhatu: Kusakwana kwemafuta ekusveta.

Mushonga: Zadza pombi nemafuta anoshanda.

Chikonzero 7: Kugadziriswa kusina kunaka kwekusiyana kwepombi kudzvinyirira.

Mushonga: gadzirisa zvakare kune inodiwa kudzvanywa.

Hydraulic pombi yemafuta ekupa haina kukwana

Troubleshooting: Mhepo yekunze inopinda mukamuri yekushanda yepombi yepiston zvichikonzera kudzikiswa kwekutama.

Kukundikana Kuongorora: Nekuda kwekushanda kwakaoma kwenzvimbo yekuchera, zviri nyore kwazvo kuti pombi yepiston iparadze pombi yekusveta kana chiteshi chekusveta haina kuvharwa zvakanaka, izvo zvinotungamira pakuyamwa kwepombi mumhepo. Plunger pombi mubasa, kana mafuta ari mukamuri yekushanda ari mumhepo, zvino kana plunger iri panzvimbo yechiteshi chekumanikidza, plunger inomanikidza mafuta nemhepo mukamuri.

Apo plunger inofamba ichienda kuzasi kwegomba rehumburumbira, pachagara paine chikamu chevhoriyamu yasara pazasi, kureva, chikamu chemafuta akamanikidzwa anochengetwa muvhoriyamu yasara yegomba. Kana iyo plunger ikaramba ichimhanya ichienda kunzvimbo yekusveta chiteshi, nekuwedzera kwehuwandu hwegomba, mafuta emukati anoderedzwa, mweya wakavharirwa muvhoriyamu yasara inowedzerwa, kuitira kuti chikamu chegomba rekushanda chigarwe nechikamu ichi. yemhepo, kuitira kuti iyo chaiyo yekusveta vhoriyamu yepombi yepiston ideredze. Kana mhepo ichipinda mumvura inosvika pachiyero chakati, ichaita kuti sisitimu ipe mafuta asina kukwana kana kusava nemafuta. Uyezve, kana iyo hydraulic oiri isingakwanise kuyerera ichipinda muchiteshi chekusveta nenguva, iyo pombi yekuyamwa inoburitsa mahomwe emhepo, nekudaro ichikonzera kukuvadzwa kusati kwasvika kune plunger chisimbiso uye plunger cylinder wall cavitation uye zvimwe zviitiko zvekutadza. Naizvozvo, matanho anofanirwa kutorwa kudzikisa kana kubvisa mweya mu hydraulic system.

Nzira dzekubvisa:

1. Ita shuwa kuti hapana kubvinza zvachose. Kuti vave nechokwadi chokuti vakavharwa zvakanaka, majoini ose epombi anofanira kusimbiswa; pamapombi episton, anofanirwa kunge aine chisimbiso chakasimba.

2. Dzivirira pombi yekusveta kuti isatsemuke kana kusveta kuti sandarara. Edza kudzora kuyerera kwemvura pachiteshi chekukwevera kudzivirira kudzvanywa panzvimbo yega yega yetambo yekukweva kubva pakudzika pane kudzvanywa kwemhepo uye kugadzira vacuum, zvichikonzera kubuda kwerabha hose, kusveta flatteni uye kupindira kwemhepo.

3. Dzora hurefu hwezinga remafuta tangi yemafuta. Kazhinji iyo yakaderera mwero wetangi remafuta uye chiteshi chekukweva cheyakareba chinhambwe chinofanira kunge chiri pasi pe0.5m; kana iyo system ichibvumira, kureba kweyero yemafuta mutangi kunofanirwa kunge kwakakwira kupfuura chiteshi chekusveta chepombi, uye kuitira kuti kupera kweiyo hydraulic system kudzokera kune pombi yemafuta kunowanzo muzinga remafuta pazasi, kuitira kuti dzivisa kugadzirwa kwemhepo inoputika.

4. Kana pane nhamba yakawanda yemhepo inoputika mutangi, inofanira kubviswa panguva yakakodzera. Kana paine mhepo yakawandisa mumvura, piston pombi inobuda pombi inokwana inogona kusunungurwa kuti ibudise mweya wepombi.
