Common Mechanical Seal Cooling Thiab Flushing Methods

Cov neeg kho tshuab foob ua kom muaj kev sib txhuam loj heev vim qhov kev sib txhuam ntawm lub ntsej muag kawg, uas ua rau qhov kub thiab txias ntawm kev sib txhuam khub nplhaib. Nyob rau tib lub sijhawm, yog tias qhov nruab nrab sealing nws tus kheej yog kub, nws yuav ua rau cov kev sib txhuam ntawm qhov kawg lub ntsej muag ib txwm ua haujlwm ntawm qhov kub thiab txias, qhov no, yog tias tsis muaj qhov ntsuas cua txias, nws yuav ua rau:
(1) Kev sib txhuam qhuav tshwm sim vim evaporation ntawm cov kua zaj duab xis ntawm lub ntsej muag kawg;
(2) Lub nplhaib sib khi ua los ntawm cov roj hmab thiab cov ntaub ntawv yas yuav muaj hnub nyoog, tawg thiab txawm tias poob;
(3) Ua kom cov nyhuv corrosive ntawm qhov nruab nrab sealing ntawm lub tshuab foob;
(4) Dynamic thiab zoo li qub nplhaib deformation;
(5) Ntxiv hnav ntawm lub ntsej muag kawg;
(6) Qhov kawg lub ntsej muag to yog loj.

Los ntawm qhov kev pom no, cov roj ntxuav thiab cov dej txias rau cov tshuab sealing yog los txo qhov kub thiab txias thaum muaj kev sib txhuam, xyuas kom meej tias muaj cov yeeb yaj kiab ua tiav ntawm qhov sib txhuam ntawm qhov chaw, txo qhov kev sib txhuam tsis zoo, txo cov kev siv hluav taws xob, thiab xyuas kom meej tias cov yeeb yaj kiab ua kua. tsis raug puas vim kub vaporization. Yog li ntawd, kev ntsuas dej ntws thiab cua txias ntawm cov tshuab foob yog qhov tseem ceeb thiab tseem ceeb txuas los xyuas kom meej tias lub tshuab foob muaj kev sib khi zoo thiab ua haujlwm ntev.
