Explosion-proof overlapping refrigeration unit maintenance

Check the explosion-proof duplex refrigeration unit and analyze the operating parameters of the chiller record table to see if there is any abnormality, check whether the explosion-proof overlapping refrigeration unit tank oil level and frozen oil emulsification, if necessary, replace the frozen oil to ensure better operation of the compressor, check the explosion-proof overlapping refrigeration unit frozen oil filter, if necessary, replace the new filter.
Check the setting value of the explosion-proof double-stacked freezer condenser high-voltage switch to ensure that the high-voltage switch is in time, and at least once a year the explosion-proof double-stacked freezer opens the valve outlet to take over, carefully inspect the valve body to see if there is corrosion, rust, fouling, leakage and other phenomena inside, if corrosion or leakage is found, the safety valve must be replaced.
check the degree of fouling of the evaporator/condenser tube of the explosion-proof duplex freezer to determine whether the cleaning cycle and water treatment of the water circulation system are appropriate, and if serious fouling is found, it should be cleaned.
the heat pipe at least once a year with rotary cleaning equipment, if the water is contaminated, cleaning should be more frequent.
Condensation pressure is too high, the unit cooling capacity is usually due to fouling in the tube, or there is air in the unit, control the cooling water out of the water temperature and condenser refrigerant temperature, if the difference between the two is greater than, the condensate pipe may scale.
Explosion-proof double-stacked refrigeration unit in the heat transfer tube cleaning process, should use a special brush, to avoid scratching and scraping the pipe wall, not available wire brush;
