Precautions for industrial chiller compressor piping

Whether it is a chiller manufacturer or a user who uses a chiller, it is clear that the compressor is the most important component of an industrial chiller, so whether it is during installation or use, pay special attention to the changes in the performance parameters of the unit In order to find and solve the problem as soon as possible.

　　 For example, in the compressor installation process, its improper piping can cause noise or abnormal vibration of the compressor and damage the compressor. In order to prevent this from happening, you need to pay attention to the following points:

　　 1. After installing the compressor welded pipes, the entire chiller system should be kept clean to avoid welding slag and other impurities from accumulating in the system, causing serious malfunctions during compressor operation.

　　2. The chiller will inevitably vibrate when it is running. In order to reduce the vibration of the pipeline, it is recommended to use copper pipes as suction and exhaust pipes. In this way, the copper pipe in the pipeline can reduce vibration when the compressor is running normally. If steel pipes are to be used for the piping in the system, proper welding techniques are very important to avoid stress in the piping system. These internal stresses will cause resonance and noise, which will reduce the service life of the compressor.

　　3. After the welding is completed, the oxidized impurities and debris generated by the welding pipeline should be removed in time. If these impurities enter the compressor, it may cause the oil filter to be blocked and cause the lubrication system and the capacity adjustment system to fail.

　　4. If the compressor suction and discharge flanges are made of cast steel, they can be directly welded to the pipeline. After welding, it should be cooled in the atmosphere, and cooling with water is prohibited.

　　In the industrial chiller refrigeration industry, the compressor is the heart of the refrigeration system. It sucks in low-temperature and low-pressure refrigerant gas from the suction pipe, drives the piston to compress it through the operation of the motor, and discharges the high-temperature and high-pressure refrigerant gas to the exhaust pipe to provide power for the refrigeration cycle, thereby achieving compression-condensation-expansion- A refrigeration cycle that evaporates and absorbs heat.
