If REFRIGERATION UNIT products are used for a long time, there will be problems such as poor cooling effect and reduction. Today, users of REFRIGERATION UNIT products do not have to worry about this problem. We provide you with the following five methods. It can guarantee the cooling effect of REFRIGERATION UNIT products all year round.
1. Regularly inspect the screw compressor of REFRIGERATION UNIT products
The compressor is the "heart" of the screw chiller, its quality directly affects the stability of the screw REFRIGERATION UNIT products in use. If the compressor fails to be repaired, the cost is relatively high, especially the high precision of the screw compressor is expensive. Therefore, if you hear abnormal sound from the compressor or other conditions, you must contact the screw chiller factory to find a professional engineer to check, find out the reason and carry out maintenance.
2. Regular cleaning of screw-type REFRIGERATION UNIT products condensers and evaporators
The condenser/evaporator is the second most important component of screw REFRIGERATION UNIT products, and it is best to clean it every six months. The cooling water of the water-cooled condenser is an open circulation loop, and the tap water used is recycled through the cooling water tower, which is easy to decompose and deposit impurities on the water pipe to form scale on the water pipe, which affects the heat transfer effect. If the scale is too thick, the cooling water circulation section will be reduced, the water volume will be reduced, and the condensing pressure will increase. Therefore, when the quality of the tap water used is poor, it is best to clean it at least once a year to remove the scale in the pipe, and it is best to perform water treatment operations on the tap water.
3. Regular inspection of screw type REFRIGERATION UNIT products safety valve
The condensers and evaporators of industrial screw chillers are all pressure vessels. According to the regulations, a safety valve should be installed on the high-pressure end of the screw chiller, that is, the condenser body. Once the chiller is in an abnormal working environment, it is safe to The valve can automatically relieve pressure to prevent possible damage to the human body caused by high pressure.
4. Regular replacement of screw type REFRIGERATION UNIT products lubricating oil
After the screw-type REFRIGERATION UNIT products are used for a long time, the oil quality of the lubricating oil will deteriorate, and the impurities and moisture inside the oil will increase, so it is necessary to observe and check the oil quality regularly. Once a problem is found, it should be replaced in time, and the brand of lubricating oil to be replaced is best provided by the original manufacturer.
5. Regular replacement of screw type REFRIGERATION UNIT products drying filter
The filter drier is an important part to ensure the normal circulation of the refrigerant. Since water and refrigerant are immiscible with each other, if the system contains moisture, it will greatly affect the operation efficiency of screw REFRIGERATION UNIT products, so it is very important to keep the inside of the system dry, and the filter element inside the drying filter must be replaced regularly.
