1. Ntawm lub lim
Raws li lub npe qhia, cov ntxaij lim dej yog siv los lim cov kua lossis roj thiab qee cov kua dej.Nws lub luag haujlwm tseem ceeb yog lim, txhawm rau ua tiav lub hom phiaj ntawm cov neeg siv.
2. Ntawm kev faib cov lim
Cov lim dej feem ntau yog muab faib ua ob pawg raws li lawv qhov raug.
1. coarse filter, tseem hu ua pre filter.Qhov sib txawv tseem ceeb yog tias lawv qhov kev lim dej feem ntau yog loj dua 100 microns (100um txog 10mm…).;
2. precision lim, tseem hu ua zoo lim.Qhov sib txawv tseem ceeb yog tias lawv qhov kev lim dej feem ntau tsawg dua 100 microns (100um ~ 0.22um).
Raws li cov khoom xav tau, lub lim tau muab faib ua peb pawg:
1. cov khoom siv carbon steel (cov ntaub ntawv zoo ib yam, xws li Q235., A3, 20#, thiab lwm yam), feem ntau yog siv rau corrosive kua lossis gases thiab lwm yam.Tau kawg, raws li lub lim rau qhov tsis zoo.Nws feem ntau yog ua los ntawm stainless hlau.
2. stainless hlau khoom (xws li 304, 316, thiab lwm yam), feem ntau yog siv rau corrosive media.Lub hauv paus yog tias cov ntaub ntawv no tuaj yeem zam tau.Cov khoom lim yog ua los ntawm stainless hlau, titanium hlau los yog PP.
3. PP cov ntaub ntawv (xws li polypropylene, polytetrafluoro, nrog rau fluorine hauv ob sab phlu lossis PO, thiab lwm yam) yog siv rau hauv cov khoom siv tshuaj xws li acid, alkali, ntsev thiab lwm yam.Cov tub ntxhais lim feem ntau yog polypropylene.
Raws li lub siab xav tau, lub lim tau muab faib ua peb pawg:
1. Tsis tshua muaj siab: 0 ~ 1.0MPa.
2. nruab nrab siab: 1.6MPa rau 2.5MPa.
3. siab siab: 2.5MPa rau 11.0MPa.
