1. Maintenance of the compressor
Taking the screw compressor as an example, the screw is a precision part, which determines the performance of the air -cooled module -type hot and cold water unit.If you often work in bad circumstances, you may fail, and the cost of maintenance is also very expensive. A small part may need at least thousands of pieces, not to mention labor costs.And if you can take regular maintenance, you can avoid the failure of the failure.It is generally tested by a professional qualification engineer for two years and one cycle.
2. Regularly detect the safety valve
The condenser is a large part of the air -cooled module -type hot and cold water units. On the screw -type air -cooled module -type hot and cold water unit, the safety valve is installed on it.The purpose of automatic pressure.Therefore, it should be checked regularly. Whether it is faulty and aging, it must be replaced if it is not qualified.
3. Wash regularly on the terrifying parts
For example, cooling water tower: larger air -cooled module -type hot and cold water units usually use the cooling water tower to cool the condenser temperature, and the water tower has a long cycle, which will also cause impurities pollution, scaling the condenser tube, etc., causing damage to the unit.So regularly cleaning the condenser will help internal cleanliness.
For example, the condenser, evaporator, heat dissipation pipe, especially the connected parts, the air -cooled module -type hot and cold water units have been running for a long time, which can easily produce scale, which will affect the cooling efficiency and heat dissipation status of the crew.EssenceWash every six months.
4. Replace the lubricant regularly
The air -cooled module hot and cold water units are also mechanical equipment, and the operation will also use lubricating oil. The working time is long, the natural oil will deteriorate, and it will penetrate the impurities such as air and water.Cold module hot and cold water units are a great thing.You have to be replaced at least once a year.
5. Regular drying filter replacement
The drying filter is a component in the refrigeration system, filtering moisture, which makes the unit full of dry refrigerant, avoiding moisture, and damage to the refrigeration system.Therefore, the dry filter has been working in the unit operation. It should be checked at least once a year. It should be checked once every six months in the bad operating environment.
6. Check the cooling dose
If it is not enough, it is necessary to replenish the refrigerant in time to avoid insufficient refrigeration effect caused by too low, and it will also cause "burns" to the unit.
7. Check whether the main line of the electronics control system is insulated from external insulation
If it is a humid environment, it should be tested frequently to ensure that the lines are normal and do not leak electricity.
8. Check the unit high and low pressure pressure switch
The unit high and low voltage switch is a device that guarantees the safety of the compressor. If it exceeds or lower than the rated pressure, the line will be automatically cut off and the compressor will stop working. If this set of values ??are not in the normal range, the compressor will be used.
9. Check the temperature controller of the unit to ensure that the temperature controller is displayed normally
The temperature controller is a device that the staff directly controls the temperature. It is displayed normally to ensure that the cold -cold module -type hot and cold water unit work normally.Therefore, check whether it is displayed and abnormal on a regular basis.
