Installation & Kho
I. Ua ntej-Kev Npaj Txhim Kho
Tshawb xyuas Specifications
Txheeb xyuas hom valve, qhov loj me, qhov ntsuas siab, qhov nruab nrab, thiab qhov ntsuas kub kom haum rau cov xwm txheej tiag tiag kom ntseeg tau tias kev ua haujlwm zoo thiab kev nyab xeeb.
Kev tshuaj xyuas qhov muag
Tshawb xyuas kev puas tsuaj sab nraud / deformation. Xyuas kom lub cev, npog, roj hmab flap tsis zoo. Tshawb xyuas kev sib txuas rau qhov tsis xws luag. Hu rau tus neeg muag khoom yog tias pom muaj teeb meem.
Cov kav dej huv huv
Ua tib zoo ntxuav cov raj xa dej uas lub valve yuav raug ntsia. Tshem tawm xeb, weld slag, sediment, thiab lwm yam., kom tsis txhob cuam tshuam nrog kev ua haujlwm nrov plig plawg thiab sealing.
II. Txhim kho kom raug
Paub meej tias Flow Direction
Txhim kho raws li cov lus qhia ntws ntawm lub cev. Media yuav tsum ntws nyob rau hauv lub xub taw qhia. Rov qab installation yuav lov tes taw lub valve thiab yuav ua rau lub cev puas.
Installation Txoj hauj lwm
1. Zoo dua rau nruab rau ntawm cov kav dej kab rov tav, tso cai rau lub ntiajteb txawj nqus los pab lub ntsej muag kaw kom zoo tshaj plaws.
2. Yog hais tias ntsia vertically, ntws yuav tsum yog upward. Muab kev ruaj ntseg mounting los tiv thaiv kev co -induced txav.
Kev sib txuas
Siv cov bolts, ceev, thiab gaskets sib xws. Tighten bolts tusyees kom nruj flange foob. Tswj flange parallelism kom tiv thaiv tsis ua haujlwm.
Zam kev ntxhov siab
Tiv thaiv kom tsis txhob muaj lub valve los ntawm kev coj tus kheej kev ntxhov siab rau sab nraud. Siv cov kev txhawb nqa, cov pob qij txha nthuav dav, thiab lwm yam, txhawm rau them nyiaj rau thermal expansion / installation yuam kev.
III. Kev tu txhua hnub
A. Tsis tu ncua ntxuav cov plua plav/roj sab nrauv kom tsis txhob muaj kab mob nkag mus.
B. Lubricate txav qhov chaw (xws li, pob khawm tus pin) nrog cov roj nplua nyeem tsim nyog thaum lub sijhawm teev tseg rau kev ua haujlwm du.
IV. Periodic Overhaul
Tsim kom muaj lub sijhawm kho dua tshiab raws li kev siv. Kev kuaj xyuas yam tsawg kawg ib xyoos yog pom zoo. suav nrog:
Tshawb xyuas cov roj hmab flap rau hnav / laus. Hloov yog tawg, deformed, los yog hnyav heev.
Tshawb xyuas lub rooj sealing nto rau kev puas tsuaj. Lap me kev puas tsuaj; hloov lub rooj zaum lossis tag nrho lub valve yog tias hnyav heev.
Xyuas lub cev / npog rau corrosion / tawg. Siv los tiv thaiv- kev kho corrosion; kho lossis hloov cov khoom uas raug mob hnyav.
