- Rau kev siv nrog strainer lossis raws li daim ntawv thov txais
- Rau "drier" daim ntawv thov siv tag nrho cov tso cai cores
- Rau 1 * lossis 2 *
MWP yuav tsum tsis txhob tsawg dua qhov siab tau teev tseg hauv sect 9.2 ntawm ANSI/ASHRAE 15 rau cov tub yees siv hauv qhov system. Tom qab them nyiaj, lub kaw lus yuav tsum tau cim nrog cov tub yees thiab roj siv.
"Lub DCRE tsuas yog siv tau rau A2L thaum muab cov tub ntxhais ua tiav. DCRE tsis raug tso cai siv los ua tus txais. "
Brazing
Vuam
Cov kev coj ua zoo tshaj plaws ntawm cov neeg siv khoom tseem yuav xav tau:
- Siv cov ntaub ntub dej thaum txhim kho.
- Braze cov pob qij txha.
- Cia lawv txias.
- Ntxuav lub brazing / vuam cheeb tsam tom qab kev teeb tsa (tshem tawm cov dej ntws ntxiv nrog txhuam).
- Qhov no yog ib qho haujlwm tseem ceeb thiab yuav tsum tau ua nrog kev saib xyuas zoo kom tshem tawm tag nrho cov dej ntws tawm.
- Xim / Anti-corrosive yuav tsum tau npog tag nrho cov qhib steel qhov chaw, qhov chaw uas cov xim dub qub tau hlawv vim brazing thiab tsawg kawg yog 3 cm ntawm tooj liab.
- Xim cov pob qij txha ob zaug.
Yuav ua li cas kom nruj cov bolts
Gasket
Tsis txhob nruab gasket ua ntej soldering.
Nco tseg: Xaiv lub hau npog Gasket raug xaiv. Muaj 2 gaskets:
- DCR thiab DCR / H
- DCRE
Kev pom zoo
Siv cov roj me me rau lub gasket ua ntej sib dhos.
Zoo dua hluavtaws POE lossis PVE roj, txawm tias cov roj siv dav dav siv tau.
Nco tseg: Tsis txhob rov siv lub gasket
Kev xaiv Fuse thiab / lossis Plug, pom zoo kom nruj torques:
Fuse: 1/4 "NPT - 3/8" Flare: 20 Nm / 14.75 ft-lb siv 2 mus rau 3 qhwv ntawm tefon daim kab xev.
Plug: 1/4 "NPT: 50 Nm / 36.87 ft-lb siv 2 mus rau 3 qhwv ntawm teflon daim kab xev.
Kev siv
Qhov tseem ceeb torque hais tsuas yog siv rau bolts muab los ntawm Danfoss.
Txhua kauj ruam yuav tsum tau ua raws li cov kab ke ntawm daim duab.
FAQ
Q: Kuv puas tuaj yeem rov siv lub gasket thaum lub sij hawm reassembly?
A: Tsis yog, lub gasket yuav tsum tsis txhob rov qab siv dua. Ib txwm siv lub gasket tshiab rau kev sib dhos.
Q: Hom roj twg yuav tsum tau siv rau lub gasket?
A: Nws raug nquahu kom siv cov roj hluavtaws POE lossis PVE roj ntawm lub gasket ua ntej sib dhos. General-purpose roj kuj tseem siv tau los ua lwm txoj hauv kev.
