Iyo hydraulic system yemuchina wekuvaka inodonha. Ndezvipi zvikonzero uye nzira yekuzvigadzirisa?

2023-10-26

Kune mhando mbiri huru dzekudonha mu hydraulic system yeinjiniya muchina, kuvuza pachisimbiso chakamisikidzwa uye kuvuza pachisimbiso chinofamba. Kudonha pachisimbiso chakamisikidzwa kunonyanya kusanganisira pasi pehumburumbira uye majoini ega ega pombi yakabatana, zvichingodaro, uye kubuda kwechisimbiso chinofamba kunosanganisira piston tsvimbo yehumburumbira yemafuta, Multi-way valve stems nezvimwe zvikamu. Kubuda kwemafuta kunogona kukamurwa kuita kubuda kwekunze uye kubuda kwemukati. Kubuda kwekunze kunonyanya kureva kudonha kwemafuta ehydraulic kubva kuhurongwa kuenda kunharaunda. Internal leakage inoreva mutsauko wepressure pakati pemativi epamusoro neakaderera.Nekuda kwezvikonzero zvakaita sekuvapo uye kukundikana kwezvisimbiso, iyo hydraulic oiri inoyerera kubva kumusoro-kudzvanywa divi kuenda kune yakaderera-kudzvanywa divi mukati mehurongwa.

 

Zvikonzero zvinokanganisa leakage:

1) Dhizaini zvinhu:

(1) Kusarudzwa kwezvisimbiso Kuvimbika kweiyo hydraulic system kunoenderana zvakanyanya Nezve dhizaini ye hydraulic system seals uye kusarudzwa kwezvisimbiso, nekuda kwekusarudzwa kusinganzwisisike kwekuisa chisimbiso magadzirirwo mukugadzira uye kusarudzwa kwezvisimbiso zvisingaite. kusangana nezviyero, mhando yekuenderana, mitoro mamiriro, uye yekupedzisira kudzvanywa kweiyo hydraulic oiri uye yekuisa chisimbiso zvinhu hazvina kuverengerwa mukugadzira. , kukurumidza kushanda, kuchinja kwekushisa kwe ambient, etc. Izvi zvose zvakananga kana zvisina kunanga zvinokonzera kubuda kwe hydraulic system kune zviyero zvakasiyana. Uye zvakare, sezvo nharaunda umo michina yekuvaka inoshandiswa ine guruva uye tsvina, yakakodzera guruva-proof zvisimbiso zvinofanirwa kusarudzwa mukugadzira. , kudzivirira guruva uye imwe tsvina kuti ipinde muhurongwa kukuvadza chisimbiso uye kusvibisa mafuta, zvichiita kuti irege kubuda.

 

(2) Zvimwe zvikonzero zvekugadzira: Kurongeka kwejometri uye kushata kwenzvimbo inofamba haina kukwana zvakakwana mukugadzirwa, uye simba rezvikamu zvekubatanidza harina kuenzaniswa mukugadzirwa. Nuclear, nezvimwewo, izvo zvinokonzeresa kuvuza panguva yekushanda kwemichina.

 

2) Manufacturing uye gungano zvinhu

(1) Manufacturing factor: Yese ma hydraulic components uye sealing parts ane yakasimba dimensional tolerances, kurapa kwepamusoro, kupedzwa kwepamusoro uye geometric tolerances, etc. Zvinodiwa. Kana kutsauka kuri kunze kwekushivirira panguva yekugadzira, semuenzaniso: piston radius ye cylinder, kudzika kana hupamhi hwechisimbiso groove, saizi yegomba rekuisa chisimbiso mhete haisi yekushivirira, kana yabuda. yeround nekuda kwematambudziko ekugadzirisa, kune maburrs kana depressions, chrome plating iri kubuda, nezvimwewo, chisimbiso chichave chakaremara, chakakwenywa, chakapwanyika kana kusabatanidzwa, zvichiita kuti chirasikirwe nekuisa chisimbiso.Chikamu chacho pachacho chichava necongenital leakage points, uye kuvuza kuchaitika mushure megungano kana panguva yekushandiswa.

 

(2) Zviitiko zveGungano: Kushanda kwakashata kwe hydraulic components kunofanira kudziviswa panguva yegungano. Simba rakawandisa rinokonzeresa deformation yezvikamu, kunyanya kushandisa tsvimbo dzemhangura kurova cylinder block, sealing flange, nezvimwe; zvikamu zvinofanira kunyatsoongororwa pamberi pegungano, uye zvikamu zvinofanira kunyatsoongororwa panguva yegungano. Nyura zvikamu mumafuta mashoma ehydraulic uye woadzvanya zvinyoro nyoro. Shandisa dhiziri paunenge uchichenesa, kunyanya zvikamu zverabha zvakadai semhete yekuisa chisimbiso, zvindori zveguruva, uye О-zvindori. Kana iwe ukashandisa peturu, ivo vanokurumidza kuchembera uye kurasikirwa nekwavo kwekutanga elasticity, nokudaro vachirasikirwa nekuisa chisimbiso chavo. .

 

3) Kusvibiswa kwemafuta uye kukanganisa kune zvikamu

 

(1) Kusvibiswa kwegasi. Pasi pekumanikidzwa kwemhepo, inenge 10% yemhepo inogona kunyungudutswa mumafuta e hydraulic. Pasi pekumanikidzwa kwakanyanya kweiyo hydraulic system, mweya wakawanda uchanyungudika mumafuta. Mhepo kana gasi. Mhepo inoumba matubu mumafuta. Kana kudzvinyirirwa kwehutsigiro hwe hydraulic huchichinja nokukurumidza pakati pepamusoro uye pasi pasi munguva shoma shoma panguva yekushanda, mabhubhu achabudisa kutonhora kwakanyanya padivi repamusoro-soro uye kuputika padivi repasi. Kana Kana paine makomba uye kukuvadzwa pamusoro pezvikamu zveiyo hydraulic system, iyo hydraulic oiri inomhanya yakananga pamusoro pezvikamu nekumhanya kukuru kuti ikurumidze kupfeka kwepamusoro, zvichikonzera kudonha.

 

(2) Particle kusvibiswa Hydraulic cylinders ndiyo huru yezvikamu zveimwe engineering mainjiniya hydraulic masisitimu. Pamusana pebasa Panguva yekuita, tsvimbo yepiston inoratidzwa uye yakanangana nenharaunda. Kunyangwe iyo giraidhi sleeve yakashongedzerwa neguruva zvindori uye zvisimbiso, guruva netsvina zvichaunzwa mu hydraulic system, ichimhanyisa makwara uye kukuvadzwa kwezvisimbiso, piston tsvimbo, nezvimwewo. kukurumidza zvinhu zvinokonzeresa kukuvadza kune hydraulic components.

 

(3) Kusvibiswa kwemvura Nekuda kwesimba rezvinhu zvakaita semamiriro ekushanda ane hunyoro, mvura inogona kupinda muhydraulic system, uye mvura inopindirana neiyo hydraulic oiri kuti igadzire asidhi Zvinhu uye sludge inoderedza kuita kwemafuta e hydraulic uye kukurumidza kupfeka. yezvikamu. Mvura inogonawo kukonzera kuti dzinde revhavha yekudzora inamire, zvichiita kuti zviome kushandisa vharafu yekudzora, kukwenya chisimbiso, uye kukonzera kubuda.

 

(4) Chikamu kukuvara kunokonzerwa nekushomeka kwemafuta. Yakagadzirwa nerabha uye zvimwe zvinhu, kuchembera, kuputika, kukanganisa, nezvimwewo nekuda kwekushandiswa kwenguva refu kuchaita kuti system irege kubuda. Kana zvikamu zvakakuvadzwa nekudhumhana panguva yebasa, zvinhu zvekuisa chisimbiso zvichange zvichikweshwa, zvichikonzera kubuda. Ndoita sei? Main Leakage Prevention and Control Countermeasures Izvo zvinhu zvinokonzeresa kuvuza kweiyo hydraulic system yemakina ekuvaka mhedzisiro yekupesvedzera kwakazara kubva kune akawanda maficha. Ne tekinoroji iripo uye zviwanikwa, zvakaoma kubvisa zvachose kudonha kweiyo hydraulic system.

 

Chete kubva pane zviri pamusoro pesvusvudziro Kutanga kubva kune zvinodonha zvinhu zveiyo hydraulic system, anonzwisisika matanho anofanirwa kutorwa kudzikisa kudonha kweiyo hydraulic system zvakanyanya sezvinobvira. Mukugadzira uye kugadzirisa zvinongedzo, izvo zvakakosha zvinokanganisa kuvuza zvinofanirwa kutariswa zvizere mukugadzira uye kugadzirisa kweiyo yekuisa chisimbiso groove.Mukuwedzera, kusarudzwa kwezvisimbiso kunokoshawo zvikuru. Kana Kutadza kunyatso funga izvo zvinopesvedzera zvinhu zvekuvuza pakutanga zvinokonzeresa kurasikirwa kusingaenzaniswi mukugadzirwa kweramangwana. Sarudza nzira dzakakodzera dzekusangana uye kugadzirisa uye dzidza kubva pane zvakaitika kare. Semuyenzaniso, edza kushandisa maturusi akakosha pakuungana kwemhete dzekuvharisa, uye Isa mamwe girizi parin'i yekuvharisa.

 

Panyaya ye hydraulic oil pollution control, isu tinofanirwa kutanga kubva kunobva kusvibisa, kusimbisa kudzora kwezvinosvibisa masosi, uye kutora nhanho dzekusefa dzinoshanda uye kuongororwa kwemhando yemafuta nguva dzose. Kuti zvibudirire kutema zvinhu zvekunze (Mvura, guruva, zvimedu, nezvimwewo) kusvibiswa kwe hydraulic cylinder, mamwe maitiro ekudzivirira anogona kuwedzerwa. Muchidimbu, kudzivirira uye kutonga kwekudonha kunofanirwa kuve kwakazara uye kutarisisa kwakazara kunogona kuwanikwa kuti kushande.
