I. Cov khoom siv thiab cov qauv tsim qauv
1. Tsawg-Qhov Kub Khoom Xaiv
Matle Statal Cov Khoom Siv: Stainless hlau 316L, OFTM A352 LCB / LC3) Anustenitic Stainless hlau (piv txwv li, 304/316 series) muaj cov khoom siv superient tsawg dua vim nws lub ntsej muag-nruab nrab ntawm cov qauv sau lotice.
● Cov khoom sib khi: Siv cov khoom siv tsawg-kub xws li PTFE-txhawb cov graphite lossis fluoroelfastomer (FKM) kom tiv thaiv Foob tawv. Rau cov kev siv ultrasonic tsawg, hloov kho rau cov hlau sib tsoo rau kev ntseeg tau.
2. Frost-resistant cov kev kho kom zoo
● Txuas txuas ntxiv valve bonnet: ib lub kaus mom ntev dua los yog sib npaug nrog 250 hli txo qhov kev pheej hmoo txias.
● Ntsug teb chaws Ntsug: Cov khoom tseem ceeb nyiam ultra-tsawg-qhov kub pob yuav tsum tau muab cov chaw tsis muaj kev ntxhov siab ntawm cov chaw sib khi.
Ii. Npaj Pre-Installation Npaj
1. Kev tu thiab ziab
● Nitrogen Sprance Retal: Siv cov nitrogen qhuav (lwg me me Vuam cov kab xev yuav tsum tau tshem tawm ntawm cov kos duab kos tawm thiab ultrasonic tu kom tiv thaiv kev thaiv lossis xeb.
● Kev kuaj mob hydostatic nrog kev kuaj mob pneumatic pneumatic (1.1 × tsim siab) thaum lub caij ntuj no kom tsis txhob tshaj tawm xov tooj.
2. Kev Kho Mob Ua Ntej
● Kev teeb tsa ua ntej ua ntej hauv -40 degree ib puag ncig rau 24 teev tshem tawm cov khoom tawg thiab txo cov kev ntxhov siab tom qab.
III. Cov txheej txheem kev tswj hwm
1. Kev Taw Qhia thiab Cov Qauv Txuas
Flow kev taug: nruj me ntsis ua raws li lub cev lub cev tus xub cim. Ntiaj teb seem yuav tsum ua kom ntseeg tau tias yog cov xov xwm ntws mus los ntawm lub rooj zaum hauv lub nroog kom tiv thaiv kev tsis txaus siab.
● Flange sib txuas: siv cov bolts rolts (piv txwv li, A193 B8M) nrog 10% nce ntxiv los piv rau kev mob khaub thuas kom raug mob.
2. Sealing Qhov Cuab
● Kev sib txuas xov: Thov cov ntsuas kub qis (piv txwv li loadtite 577) ua ke nrog multi-ulat gaskets los txhim kho airtightness.
● Cov khoom siv roj hmab yooj yim: ua ntej ua ntej cov roj hmab sib koom ua ke hauv ib cheeb tsam ntau dua lossis sib npaug rau 10 degree los rov elasticity ua ntej kev teeb tsa.
IV. Kev Tiv Thaiv thiab Txij Nkawm
1. Kev ntsuas khov khov khov
● Cov khoom siv hluav taws xob hauv hluav taws xob: txhim kho ntau dua lossis sib npaug ntawm cov kav valve thiab cov ntsaws ruaj ruaj kom muaj kev kub ntxhov ntau dua lossis sib npaug}} degree.
● Kev Nyab Xeeb Kev Nyab Xeeb: Khoom siv ntau dua li ntau dua los yog sib npaug rau 1.2M txuas ntxiv kom tiv thaiv kev sib cuag nrog hlau txias.
2. Txij Nkawm Muaj Kev Lag Luam
Rain foob cov tshev nyiaj ncaj ncees: Cov Helium Pawg Huab Cua Sov Spectrometer Txhij<1×10⁻⁶ mbar·L/s) ensures sealing performance.
It Lubrication: Pib dua-kub roj (piv txwv li, Molykote GN series) ib hlis twg los tswj kev mus ncig taus.
