Industrial water chiller is a kind of water cooling equipment, which can provide constant temperature, constant current and constant pressure. The principle of his work is to inject a certain amount of water into the water tank in advance, cool the water through the cooling system of the chiller, and then send the low-temperature cooling water to the equipment to be cooled by the water pump. The cooling water of the chiller takes the heat away and the temperature rises and then returns to the water tank, so as to achieve the effect of cooling.
The operation of chiller system is through three interrelated systems: refrigerant circulation system, water circulation system and electrical automatic control system. Refrigerant circulation system of industrial water chiller: the liquid refrigerant in the evaporator absorbs the heat of water and begins to evaporate. There is a certain temperature difference between the refrigerant and water. The liquid refrigerant is also completely evaporated and becomes gaseous, which is then inhaled and compressed by the compressor (pressure and temperature increase). The gaseous refrigerant absorbs heat through the condenser (air cooling / water cooling), condenses into liquid, and passes through the condenser After throttling, the thermal expansion valve (or capillary) turns into low temperature and low pressure refrigerant and enters the evaporator to complete the refrigerant circulation process.
Compressor is the core component of the whole refrigeration system, and also the power source of refrigerant compression. Its function is to convert the input electric energy into mechanical energy and compress the refrigerant.
Check the compressor of industrial water chiller after 1000 hours of operation：
Is the lubricating oil normal？
Whether the current of compressor is normal during operation？
Whether there is abnormal sound when the compressor is running.
The noise produced by compressor interlacing can be eliminated or adjusted from the following aspects：
The dynamic balance and static balance of running parts are measured;
The reasonable selection of inlet and outlet pipes, especially the position, length and diameter of the inlet pipe, has a great influence on the performance and noise of the compressor;
The structure, shape, wall thickness and material of compressor shell are directly related to the noise elimination effect;
During the installation and maintenance, the bending radius of the connecting pipe is too small, the opening clearance of the stop valve is too small, the system is blocked, the use of the connecting pipe does not meet the requirements, and the specification is too small and too short, all these factors will increase the operation noise;
The refrigerant oil injected into the compressor should be appropriate. A large amount of oil can enhance the lubrication effect. But it increases the sound of the parts stirring the oil. Therefore, the amount of circulating oil in the refrigeration system should not exceed 2%;
In order to reduce the noise, a reasonable bearing clearance should be selected, and a smaller fit clearance can be used under the condition of good lubrication;
The insulation damping pad between the compressor shell and pipeline should meet certain requirements. If it is found that the compressor has cylinder sticking or shaft holding after inspection, the serious rotor blocking may cause the rapid increase of current and burn the motor. For axle holding and slight cylinder sticking.
