Yoglub chiller is used in the industry, it is easy to form scale in the condenser pipeline. If it is not dealt with in time, these scales will affect the heat exchange effect, resulting in an increase in the condensing temperature of the unit, which in turn leads to a decrease in the cooling capacity and an increase in the power consumption of the unit. The main reason for the formation of scale is actually that the calcium and magnesium ions in the cooling water crystallize and precipitate in the form of salt when heated and condense on the inner wall of the copper pipe; the metal oxidation products of the system pipeline; the slime caused by bacteria and algae, etc. Therefore, the condenser of the chiller should be cleaned frequently, and the cleaning time can be determined according to the water quality and scaling, but at least once a year. Let's take a closer look at the two main methods of chemical cleaning and physical cleaning to remove scale.
1. Add the cleaning liquid to the cooling water system in a certain proportion, and turn on the cooling pump to circulate for 12-24 hours. The sediment layer is continuously dissolved and dropped by the chemical action and scouring action of the cleaning liquid. However, this method requires a lot of cleaning potions and is costly.
2. Txuas lub twj tso kua mis thiab lub raj xa dej ntawm lub tshuab ntxuav lub tank thiab lub condenser los tsim ib lub voj kaw, kom cov kua ntxuav tu tuaj yeem txuas mus ntxiv rau 12-24 teev kom yaj thiab poob tawm ntawm cov pob zeb.
3. Sib tov cov kua tshuaj ntxuav hauv ib qho kev faib ua feem, ntxiv rau hauv lub condenser thiab cia nws sawv ntsug rau 5-10 teev kom soften thiab yaj cov sediment, ntws cov kua ntxuav, thiab yaug nrog dej huv.
Qhov kom zoo dua ntawm kev ntxuav cov tshuaj yog tias cov nplai raug tshem tawm tag nrho, uas tuaj yeem txo qhov kev ua haujlwm ntawm cov neeg ua haujlwm. Yog li ntawd, thaum ua cov tshuaj ntxuav tu, peb yuav tsum tau them sai sai rau qhov kev faib ua feem ntawm kev daws, kev ncig thiab so lub sij hawm los tiv thaiv lub condenser los ntawm corroded.
Txoj kev ntxuav lub cev: feem ntau yog siv txhuam txhuam txhuam los ntxuav. Lub taub hau hloov tau yog tsav los ntawm lub cev muaj zog ntawm lub tshuab ntxuav. Muaj ib tug nylon txhuam nyob rau hauv pem hauv ntej ntawm lub saj zawg zog ncej. Thaum siv, cov ncej hloov tau yooj yim thiab txhuam tau muab tso rau hauv lub raj tooj liab ntawm lub condenser, thiab txhuam hauv lub raj tooj liab raug tshem tawm los ntawm kev sib hloov ceev ceev. Av, thiab thaum kawg yaug nrog dej, lub tshuab no tseem hu ua rab phom tshuab.
Qhov kom zoo dua ntawm kev tu lub cev yog tias nws txuag tau tus nqi ntawm cov tshuaj ntxuav tu, zam cov kua khib nyiab pov tseg tom qab ntxuav cov tshuaj, thiab tsis yooj yim ua rau corrosion ntawm lub condenser tooj liab raj. Qhov tsis zoo yog tias cov nyhuv tu tsis zoo rau cov nplais tawv thiab cov khoom siv corrosion nrog muaj zog adhesion. Yog, thiab kev ua haujlwm tu yog siv sijhawm thiab siv zog ua haujlwm.
