Koj paub ntau npaum li cas txog kev ntim cov ntsaws ruaj ruaj?

Sij hawm: 2021-12-08 Hits: 7

Yuav ua li cas xaiv txoj kev sib khi thaum tsim lub tshuab? Tsab ntawv xov xwm no yuav coj koj los nkag siab txog cov ntaub ntawv sib foob zoo sib xws hauv kev tsim kho tshuab. Lawv yog packing foob, mechanical seal, qhuav roj foob, labyrinth foob,

roj foob, dynamic foob thiab muab kauv foob. Hnub no, cia peb tham txog kev ntim khoom ua ntej!

Packing foob

Cov ntsaws ruaj ruaj tuaj yeem muab faib ua cov ntim khoom muag, cov ntim ntim nyuaj, thiab molded ntim cov ntsaws ruaj ruaj raws li lawv cov yam ntxwv.

1) soft packing seal

Mos packing hom: Packing

Packing feem ntau yog woven los ntawm softer threads, uas yog sau nyob rau hauv lub kaw kab noj hniav los ntawm strips nrog ib tug square cross-sectional cheeb tsam. Lub zog nias yog tsim los ntawm lub caj pas kom compress lub ntim thiab yuam kom cov packing 

nias rau ntawm qhov chaw sealing (ncej). Nyob rau sab nrauv thiab cov kab noj hniav kaw), lub zog radial rau cov nyhuv sealing yog tsim, yog li ua si lub luag haujlwm sealing.

Muaj feem xyuam rau lub sijhawm rau kev ntim khoom muag:

Cov khoom ntim khoom xaiv rau packing txiav txim siab sealing nyhuv ntawm packing. Feem ntau hais lus, ntim cov ntaub ntawv raug txwv los ntawm qhov kub, siab thiab pH ntawm qhov nruab nrab ua haujlwm, thiab qhov roughness ntawm qhov chaw thiab

eccentricity ntawm cov cuab yeej siv tshuab uas ua haujlwm packing Thiab kab ceev, thiab lwm yam., kuj tseem yuav muaj cov cai rau kev xaiv cov khoom ntim.

Graphite packing tuaj yeem tiv taus qhov kub thiab txias, thiab yog ib qho ntawm cov khoom siv tau zoo tshaj plaws los daws qhov teeb meem ntawm qhov kub thiab txias siab sealing. Corrosion tsis kam, zoo sealing ua tau zoo

-ance, ruaj khov thiab txhim khu kev qha muaj nuj nqi.

Aramid packing yog ib hom muaj zog organic fiber ntau. Lub woven packing yog impregnated nrog polytetrafluoroethylene emulsion thiab lubricant.

Polytetrafluoroethylene packing yog ua los ntawm cov ntshiab polytetrafluoroethylene dispersion resin li raw khoom, thawj zaug ua rau hauv cov yeeb yaj kiab nyoos, thiab tom qab ntawd twisted, braided thiab woven rau hauv packing. Nws tuaj yeem siv dav hauv zaub mov, tshuaj,

papermaking, tshuaj fiber ntau, thiab lwm yam. yuav tsum tau huv huv, thiab li qub thiab twj tso kua mis uas muaj zog corrosive media.


2. Hard packing foob

Muaj ob hom kev ntim khoom nyuaj: cais lub nplhaib thiab cov nplhaib sib cais.
