Kev Ua Yuav Tsum Ua Rau Flange Sealing Surface
Jul 11, 2018| Qhov paug ntawm qhov flange sealing nto deg yog qhov tseem ceeb tshaj uas cuam tshuam cov kev sib tw seev cev. Nws tau raug kuaj xyuas tias thaum cov qhov fais fab ntawm qhov flange sealing ntws yog txog Ra3.2μm, cov huab cua uas muaj hlau asbestos ncoo yog siv los muab cov huab cua nrog lub siab ntawm 0.49 MPa, thiab qhov tshwm sim tawm qhov me me; thaum lub qhov chaw ruaj khov yog txo mus txog rau 1.6 μm, qhov kev sib khi zoo.
Ntau tus qauv flange tag nrho yuav tsum muaj rau qhov chaw npoo ntawm qhov chaw ntub dej, tab sis vim muaj ntau yam roj av, cov kev cai roughness sib txawv, thiab cov qauv tsis tuaj yeem teev ib los ntawm ib qho. Thaum siv hlau npog ncoo, hlau toothed ncoo, hlau nthwv ncoo thiab hlau ntaub qhwv, qhov chaw npoo ntawm qhov flange sealing ntim yuav tsum yog Ra 3.2 mus rau 1.6 μm, uas yog qhov nyuaj rau kev ua tus loj diameter flange nto. Cov ntawv nplaum graphite nyob saum npoo tuaj yeem tsiam rau cov kev tsis zoo uas tshwm sim los ntawm qhov loj qhov chaw roughness.
