Peb Qhov Ua Rau Hydraulic Seals Failure

1 (3)

Thaum siv lub tog raj kheej hydraulic, qhov teeb meem ntawm kev foob tsis ua haujlwm feem ntau tshwm sim, uas cuam tshuam rau kev ua haujlwm ib txwm muaj. Kev puas tsuaj ntawm hydraulic lub tog raj kheej foob yog lub ntsiab yog vim li cas rau qhov tsis ua hauj lwm ntawm lub foob.

1) Sealing nto hnav. Thaum lub sijhawm ua haujlwm ntawm lub tog raj kheej hydraulic, kev sib txhuam ntawm lub foob thiab cov hlau nto yog tshwm sim los ntawm zawv zawg, uas yooj yim ua rau lub foob hnav. Cov impurities nyob rau hauv cov roj, tshwj xeeb tshaj yog hlau hais, los yog ntau heev nto roughness ntawm cov hlau thiab nruj packing yuav exacerbate qhov teeb meem no.

2) Qhov teeb meem ntawm extrusion deformation. Ib qho teeb meem uas yuav tsum tau ua yog tias thaum muaj kev kub ntxhov, lub foob ntawm lub tog raj kheej hydraulic yog nquag ua rau liquefaction, thiab tom qab ntawd nkag mus rau qhov sib txawv ntawm qhov sealing nto. Thaum lub hydraulic lub tog raj kheej foob txav mus rau qhov sib khi zawj, nws yog qhov tsim nyog rau qhov tshwm sim ntawm qhov teeb meem no, thiab qhov sib txawv extrusion ua rau lub foob puas tag, txawm tias qhov chaw tawg, lossis yas deformation. Yog tias koj xav zam qhov teeb meem no, koj tuaj yeem ntxiv lub nplhaib sealing.

3) Kuj tseem muaj qhov teeb meem flipping. Thaum cov khoom siv hydraulic ua haujlwm, nws yuav ua rau muaj kev kub ntxhov ntau hauv qhov sib khi. Nyob rau hauv qhov kev txiav txim ntawm lub siab, hauv qab ntawm hydraulic lub tog raj kheej foob yog yooj yim heev rau hnav, thiab tom qab ntawd lub foob raug muab tso rau hauv qhov kev txiav txim ntawm kev sib txhuam thiab tshem tawm ntawm lub foob. Lub sealing zawj yog protruded, lub sealing di ncauj yog txiav los yog crushed, thiab lub foob raug puas lawm.

4) Tsis tas li ntawd, muaj qhov tshwm sim ntau heev hu ua eccentric hnav, uas kuj yog ib qho ntawm cov laj thawj tseem ceeb rau kev puas tsuaj ntawm hydraulic lub tog raj kheej seals. Vim yog qhov teeb meem tseem ceeb ntawm lub foob, los yog qhov eccentricity ntawm lub sealing kev them nyiaj yug nto, nws kuj yuav yog vim ib nrab burrs nyob rau hauv mating nto ntawm lub reciprocating keeb thiab lub foob thiab radial loads, thiab lwm yam., uas yuav ua rau eccentric hnav.

5) Material aging. Vim lub sij hawm siv ntev los yog lub sij hawm cia ntev, hydraulic lub tog raj kheej ntsaws ruaj ruaj yog oxidized thiab ua nyuaj thiab nkig, poob lawv thawj elasticity thiab yog li poob lawv sealing kev ua tau zoo.

6) Tolerance yog vim li cas

Kev sib dhos kom raug yog qhov tsim nyog rau kev teeb tsa lub tog raj kheej foob, thiab lub tog raj kheej (lub tes tsho) yuav tsum muaj qhov tsim nyog roughness thiab qhov loj me. Qhov no yuav tsum tau hais tias qhov tseeb qhov ntev thiab geometric kam rau ua ntawm lub foob yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm daim duab kos, txwv tsis pub nws yuav yooj yim ua rau tsis ua hauj lwm ntxov ntawm lub foob.

Cov saum toj no yog vim li cas rau qhov tsis ua hauj lwm ntawm lub tog raj kheej seals. Kuv ntseeg tias koj tuaj yeem nkag siab zoo dua cov tshuab foob tom qab nkag siab lawv. Peb lub tuam txhab yog cov chaw tsim khoom ntawm cov ntsaws ruaj ruaj, yog tias koj xav yuav cov ntsaws ruaj ruaj, koj tuaj yeem tiv tauj peb.Qhov saum toj no yog peb qhov laj thawj rau kev tsis ua haujlwm ntawm cov tshuab foob. Kuv ntseeg tias koj tuaj yeem nkag siab zoo dua cov tshuab foob tom qab nkag siab lawv. Peb lub tuam txhab yog cov chaw tsim khoom ntawm cov ntsaws ruaj ruaj, yog tias koj xav yuav cov ntsaws ruaj ruaj, koj tuaj yeem tiv tauj peb.
