Yuav ua li cas xaiv cov khoom siv rau cov tshuab foob

Xaiv cov khoom siv rau koj lub foob yog qhov tseem ceeb vim nws yuav ua lub luag haujlwm hauv kev txiav txim siab qhov zoo, kev ua neej nyob thiab kev ua haujlwm ntawm daim ntawv thov, thiab txo cov teeb meem yav tom ntej.

Kev xaiv cov khoom siv feem ntau siv rau cov tshuab foob.

1. Cov dej huv, qhov kub thiab txias. Lub nplhaib txav: 9Cr18, 1Cr13, ntog cobalt chromium tungsten, cam khwb cia hlau; Lub nplhaib zoo li qub: resin impregnated graphite, bronze, phenolic yas.

2. Dej dej (muaj cov av khib nyiab), qhov kub thiab txias. Dynamic nplhaib: tungsten carbide;

Lub nplhaib ruaj ruaj: tungsten carbide.

3. Dej hiav txwv, kub ib txwm txav nplhaib: tungsten carbide, 1Cr13 surfacing cobalt chromium tungsten, cam khwb cia hlau; Lub nplhaib zoo li qub: resin-impregnated graphite, tungsten carbide, cermet.

4. Superheated dej 100 degrees. Lub nplhaib txav: tungsten carbide, 1Cr13, cobalt chromium tungsten surfacing, cam khwb cia hlau; Lub nplhaib zoo li qub: resin-impregnated graphite, tungsten carbide, cermet.

5. Roj av, lubricating roj, kua hydrocarbons, ib txwm kub. Lub nplhaib txav: tungsten carbide, 1Cr13, cobalt chromium tungsten surfacing, cam khwb cia hlau; Lub nplhaib zoo li qub: impregnated nrog resin lossis tin-antimony alloy graphite, phenolic yas.

6. Roj av, lubricating roj, kua hydrocarbon, 100 degrees txav nplhaib: tungsten carbide, 1Cr13 surfacing cobalt chromium tungsten; Static nplhaib: impregnated bronze los yog cob graphite.

7. Roj av, lubricating roj, kua hydrocarbons, uas muaj hais. Dynamic nplhaib: tungsten carbide; Lub nplhaib ruaj ruaj: tungsten carbide.

Hom thiab kev siv cov khoom siv sealing sealing cov ntaub ntawv yuav tsum ua tau raws li qhov yuav tsum tau ua ntawm sealing muaj nuj nqi. Vim muaj cov xov xwm sib txawv kom raug kaw thiab sib txawv ua haujlwm ntawm cov khoom siv, cov ntaub ntawv sib khi yuav tsum muaj qhov sib txawv. Cov kev xav tau rau cov ntaub ntawv sealing feem ntau yog:

1. Cov khoom siv muaj qhov ntom ntom zoo thiab tsis yooj yim rau kev xau tawm.

2. Muaj qhov tsim nyog txhua yam muaj zog thiab hardness.

3. Zoo compressibility thiab resilience, me me mus tas li deformation.

4. Tsis soften los yog decompose ntawm qhov kub thiab txias, tsis tawv los yog tawg ntawm qhov kub thiab txias.

5. Nws muaj kev tiv thaiv corrosion zoo thiab tuaj yeem ua haujlwm ntev hauv cov kua qaub, alkali, roj thiab lwm yam xov xwm. Nws ntim thiab hardness hloov me me, thiab nws tsis ua raws li cov hlau nto.

6. Me me kev sib txhuam coefficient thiab zoo hnav tsis kam.

7. Nws muaj qhov yooj yim los ua ke nrog lub sealing nto.

8. Kev laus ua haujlwm zoo thiab ruaj khov.

9. Nws yog ib qho yooj yim rau txheej txheem thiab tsim khoom, pheej yig thiab yooj yim kom tau cov ntaub ntawv.

Roj hmab yog cov khoom siv feem ntau siv sealing. Ntxiv rau cov roj hmab, lwm cov ntaub ntawv sib khi tsim nyog suav nrog graphite, polytetrafluoroethylene thiab ntau yam sealants.
