Daim ntawv qhia ntawm cov khoom siv rau mechanical seals

Cov khoom siv zoo ntawm cov tshuab foob yuav ua rau koj zoo siab thaum thov.

Mechanical seals tuaj yeem siv rau hauv ntau yam khoom siv nyob ntawm daim ntawv thov seals. Los ntawm kev xaiv cov khoom raug rau kojtwj foob, nws yuav siv sij hawm ntev heev, tiv thaiv kev tu thiab tsis ua haujlwm.

Dab tsi yog cov khoom siv raumechanical foobs?

Ntau yam khoom siv tuaj yeem siv rau cov ntsaws ruaj ruaj nyob ntawm qhov yuav tsum tau ua thiab ib puag ncig lawv yuav raug siv rau. Los ntawm kev txiav txim siab ntawm cov khoom siv xws li hardness, nruj, thermal expansion, hnav thiab tshuaj tiv thaiv, koj tuaj yeem nrhiav cov khoom zoo tshaj plaws rau koj lub tshuab foob.

Thaum cov tshuab foob ua ntej tuaj txog, lub ntsej muag foob feem ntau yog ua los ntawm cov hlau xws li cov hlau tawv tawv, tooj liab thiab tooj liab. Tau ntau xyoo, cov khoom siv txawv txawv tau siv rau lawv cov khoom zoo, nrog rau cov ceramics thiab ntau qib ntawm cov tshuab carbon.

Daim ntawv teev cov khoom siv feem ntau rau lub ntsej muag foob

Carbon (CAR) / Ceramic (CER)

Cov khoom no feem ntau muaj 99.5% txhuas oxide uas muaj kev puas tsuaj zoo vim nws qhov tawv. Raws li cov pa roj carbon monoxide inert nws tuaj yeem tiv taus ntau yam tshuaj sib txawv, tab sis nws tsis haum thaum thermally 'shocked'. Nyob rau hauv qhov kub hloov pauv nws tuaj yeem tawg lossis tawg.

Silicone Carbide (SiC) thiab sintered silicone carbide

Cov khoom no yog tsim los ntawm kev sib xyaw silica thiab coke thiab muaj tshuaj zoo ib yam li Ceramic, tab sis nws tau txhim kho lubrication zoo thiab nyuaj dua. Silicone carbide lub hardness ua rau nws yog ib qho zoo heev-nrhiav kev daws teeb meem rau hnyav ib puag ncig thiab nws tseem tuaj yeem rov lapped thiab polished los kho lub foob ntau zaus hauv nws lub neej.

Tungsten Carbide (TC)

Cov khoom siv ntau yam zoo lisilicone carbidetab sis nws yog ntau haum rau kev siv siab siab vim muaj siab elasticity nyob rau hauv kev sib piv. Qhov no tso cai rau 'flex' me ntsis thiab tiv thaiv lub ntsej muag distortion. Raws li nrog Silicone Carbide nws tuaj yeem rov lapped thiab polished.
