Lub freezer tub yees compressor, condensing units

Yuav ua li cas ntws, sim thiab debug lub tub yees system

1. Lub hom phiaj ntawm blowdown ntawm lub tub yees system yog los xyuas kom meej lub sab hauv cleanliness ntawm lub system.Yog hais tias muaj ntau yam impurities thiab hmoov seem nyob rau hauv lub system, nws yuav ua rau lub blockage ntawm cov yeeb nkab txias ntawm lub qhov throttle, thiab ua rau muaj teeb meem me me xws li fluffing thiab muaj kev sib txhuam thaum ua haujlwm.Nws yuav ua rau kev puas tsuaj rau lub tub yees;
2. Cov ntsiab lus cuam tshuam txog kev xau kom pom ntawm lub tub yees system
ib.Lub hauv paus ntawm lub tshuab xau ntawm lub tub yees yuav tsum tau txiav txim siab raws li hom refrigerant xaiv, cov txheej txheem txias ntawm lub tub yees thiab txoj hauj lwm ntawm cov yeeb nkab seem;
b.Rau cov tshuab hluav taws xob siab, feem ntau yuav tsum tau npaj siab txog ntawm 1.25 npaug ntawm cov cua txias, uas yooj yim rau kev soj ntsuam thiab xav paub ntau ntxiv yam tsis muaj kev puas tsuaj rau lub tub yees;
c.Cov pa nqus kom pom qhov siab ntawm qhov qis-siab feem ntau yog hais txog 1.2 npaug ntawm lub siab saturation nyob rau lub caij ntuj sov;
2. Cov ntsiab lus ntsig txog kev debugging ntawm lub tub yees system
1. Txheeb xyuas seb qhov qhib thiab kaw ntawm txhua lub valve hauv lub tub yees puas yog qhov qub, tshwj xeeb tshaj yog lub kaw-off valve yuav tsum qhib;
2. Xyuas seb qhov dej txias ntawm lub condenser yog qhib, thiab seb qhov kev sib hloov ntawm cov kiv cua ntawm cov cua condenser puas yog;
3. Ua ntej pib lub tub yees, nws yog ib qho tsim nyog yuav tsum tau sim seb qhov hluav taws xob tswj hluav taws xob puas yog thiab ntsuas seb qhov hluav taws xob ntawm lub hwj chim yog qhov qub;
4. Paub meej tias seb cov roj qib ntawm lub crankcase ntawm lub tub yees compressor yog qhov qub thiab ua raws li kab rov tav nruab nrab ntawm cov iav pom;
5. Pib lub tub yees compressor thiab xyuas seb nws puas khiav zoo li qub.Piv txwv li, txoj kev sib hloov puas yog?Puas yog lub suab khiav zoo li qub?
6. Tom qab pib lub tub yees compressor, saib seb tus nqi ntawm qhov ntsuas siab thiab qis ntawm lub compressor puas tsim nyog;
7. Nyob rau hauv kev khiav hauj lwm, mloog lub suab ntawm cov tub yees ntws nyob rau hauv lub expansion valve thiab xyuas seb puas muaj condensation los yog te nyob rau hauv lub pipeline tom qab lub expansion valve.Lub tshuab tub yees ib txwm ua haujlwm ntawm kev thauj khoom thaum ntxov ntawm kev ua haujlwm, uas tuaj yeem nkag siab qhov kub ntawm lub tog raj kheej taub hau;
8. Thaum debugging tub yees cov khoom, xyuas kom meej tias lub siab thiab voltage relays, roj siab sib txawv relays, dej txias thiab chilled water cut-off relays, chilled dej khov tiv thaiv relays thiab kev ruaj ntseg li qub ntawm lub system nyob rau hauv ib txwm ua hauj lwm tej yam kev mob;
