Cov Kev Xyuam Muag Kev Tiv Thaiv Kev Siv R404A Hauv Piston Tub Yees Compressors

Cov Kev Xyuam Muag Kev Tiv Thaiv Kev Siv R404A Hauv Piston Tub Yees Compressors

1. Cov roj txuam nrog: yuav tsum siv cov roj hluav taws xob hluav taws xob hluav taws xob (poe); Cov roj ntxhia tsis sib xws nrog R404A thiab yuav ua rau lubrication tsis ua haujlwm.

2. Cov khoom haum: Ua kom cov txheej txheem system (li qub (cov li qub, gaskets, hoses) yog resistant rau r404a. Zam kev siv roj hmab zoo tib yam; Siv EPDM lossis Viton cov ntsaws ruaj ruaj kom tiv thaiv kev o thiab to.

3.. Kev tswj siab: R4040 muaj qhov ntsuas siab dua ntau dua li cov tub yees ib txwm (piv txwv li R22). Nruj me ntsis saib xyuas qhov tawm kom tsis txhob muaj kev tawm tsam kom tiv thaiv compressor overload lossis kheej kheej tawg.

4. Lub tshuab nqus tsev yuav tsum tau: Ua tiav lub tshuab nqus tsev sib sib zog nqus (tsawg dua los yog sib npaug nrog 50pa) ua ntej them. Residual huab cua lossis noo noo yuav hnov ​​mob nrog R404A los tsim cov tshuaj acidic, corroding lub compressor thiab thaiv cov kab ke.

6. Kev Tshawb Pom: Siv Nitrogen Siab Test + Nqus Plav Tuav Rau Kev Siv Kom Tshawb Nrhiav. Dej xab npum kuj tseem siv tau rau cov tshev hauv zos, tab sis zam kev siv cov tub yees rau hauv lub tub yees kom tiv thaiv kom tsis txhob muaj kuab paug thiab ib puag ncig.

7. Kev tiv thaiv kev nyab xeeb: hnav looj tes looj hnab looj tes thiab cov phiaj xwm kev ua haujlwm. R404A yog tsawg {- lom thiab tuaj yeem ua rau te dej yog tias nws nkag mus rau hauv kev sib chwv nrog daim tawv; Ua kom zoo cua nyob hauv thaj chaw ua haujlwm.
