The maintenance of refrigerants and refrigeration unit

the main content of the refrigeration unit protection maintenance, including normal maintenance and repair regularly. Timing of the repair maintenance to ensure its normal operation for a long time, extend the use life of crew, also can save energy consumption of refrigeration. About water chiller, should be running records, records of the unit under operation condition, and to build a new repair technology archives. Good technical information to help find something wrong with danger, adopt measures as early as possible, in case to put barrier.

refrigeration compressor unit, is in the unit is very crucial parts, the stand or fall of compressor is directly related to the stability of the unit. If the compressor attacks. Because of the compressor equipment has high accuracy request, generally need to please the manufacturer for repair.

1, replace lubricating oil

refrigeration unit after long time use, lube oil quality is poor, oil inside the impurities and moisture increase, so make survey and check the oil regularly. Once found that the problem should be timely replacement, replace lubricating oil brand is necessary to conform to the technical data.

2, replace the boring filter

boring filter is a major part of the guarantee refrigerants for regular cycle. Because water and refrigerant miscibility, if the system contains moisture, will greatly affect the unit running power, which is mainly to adhere to the system is boring, boring inside the filter cartridge is necessary to replace regularly.

3, the safety valve calibration

chiller on the condenser and evaporator are in pressure vessel, according to the regulation, should be in high voltage side of the unit condenser device safety valve on the body, once the unit is in abnormal working environment, safety valve can active pressure, in order to avoid high pressure may cause harm to human body. So the valve timing check about the safety of the whole units is very important.

4, condenser and evaporator clean

because of water cooled condenser cooling water is open loop, tap water is generally selected by the cooling tower circulation use. When the calcium salt and magnesium salt in the water content is larger, it is easy to differentiate and deposited on the cooling water pipe and scale, affect the heat transfer. Scale too thick will make the cooling water flow section, water cut, condensing pressure rise. Therefore, when the use of cooling water quality is poorer, the cooling water pipe cleaning at least once a year, remove the furring in the pipe and other dirt. To clean the condenser pipe generally has the following two kinds:

( 1) Using special pigging gun to clean the pipe.

( 2) Using special cleaner scour, or filling in the cooling water, after waiting for 24 h after the replacement solution, washed until the stop.

5, refrigerant charging

if there is no other special factors, generally unit won't attack a lot of leakage. If because of improper use or after the repair, have a certain amount of refrigerant leakage. Will need to increase the refrigerant from the beginning. Charging refrigerant is necessary to pay attention to the unit using refrigerant trademark.

Hangzhou E cool refrigeration Co.,Ltd thinks that that firms can avoid the artificial choice between quantitative and qualitative risk management, allowing both to play important roles in surfacing and assessing risks.

Hangzhou E cool refrigeration Co.,Ltd is committed to supplying the consumer and our customers with the finest, high-quality products and to leading the industry in refrigerant gas start capacitor suppliers.
