Pob valve installation thiab txij nkawm
1. Nruab lub pob valve
1. Nruab lub valve ntawm cov yeeb nkab. Qhov kawg ntawm lub valve tuaj yeem ntsia tau rau ntawm qhov kawg ntawm qhov kawg. Tus kov actuated valve tuaj yeem ntsia tau rau txhua qhov chaw ntawm cov kav dej. Tab sis pob li qub los yog pneumatic drives nrog gearboxes yuav tsum tau ntsia vertically, piv txwv li nyob rau hauv kab rov tav yeeb nkab nrog tsav saum cov yeeb nkab.
2. Nruab gaskets nruab nrab ntawm lub valve flange thiab cov yeeb nkab flange raws li kev tsim cov kav dej.
3. Lub bolts ntawm lub flange yuav tsum tau nruj nreem symmetrically, tsis tu ncua thiab tusyees
4. Txuas cov kab pneumatic (thaum siv lub tshuab pneumatic)
Xyuas tom qab installation
1. Ua haujlwm tus neeg tsav tsheb ob peb zaug kom qhib thiab kaw lub pob valve. Nws yuav tsum yoog raws thiab tsis nres kom paub meej tias nws ua haujlwm
2. Txheeb xyuas qhov kev ua tau zoo ntawm cov flange kev sib txuas ntawm lub raj xa dej thiab lub pob valve raws li cov qauv tsim cov kav dej.
2. Kev tu lub pob valve
◆ Ua ntej dismantling, koj yuav tsum xub xyuas seb cov kav dej sab sauv thiab sab qis ntawm lub pob valve tau muaj kev ntxhov siab.
◆ Thaum lub sij hawm disassembly thiab reassembly, yuav tsum tau saib xyuas kom tsis txhob muaj kev puas tsuaj rau lub sealing nto ntawm qhov chaw, tshwj xeeb tshaj yog cov khoom tsis yog hlau. Cov cuab yeej tshwj xeeb yuav tsum tau siv thaum tshem O-rings
◆ Thaum txhim kho, cov bolts ntawm flange yuav tsum tau nruj me ntsis thiab sib npaug.
◆ Tus neeg saib xyuas yuav tsum sib haum nrog cov khoom siv roj hmab, cov khoom yas, cov khoom siv hlau thiab cov khoom nruab nrab (xws li roj) hauv lub pob valve. Thaum qhov nruab nrab ua haujlwm yog roj, roj av (GB484-89) tuaj yeem siv los ntxuav cov hlau. Ntxuav cov khoom tsis yog xim hlau nrog dej huv lossis cawv
◆ Tshem tawm ntawm ib tus neeg tuaj yeem raug ntxuav los ntawm kev nkag mus rau hauv dej. Cov khoom siv hlau nrog cov khoom tsis muaj hlau tsis muaj hlau tuaj yeem txhuam nrog cov ntaub so ntswg huv so hauv xab npum (kom tiv thaiv cov fibers los ntawm kev poob thiab ua rau cov khoom). Thaum ntxuav, tag nrho cov roj, av, kua nplaum, plua plav, thiab lwm yam adhering rau phab ntsa yuav tsum tau muab tshem tawm.
