How to troubleshoot the low condensation pressure of the laser chiller?

Laser chillers are mainly used in laser processing equipment such as laser marking machines, laser engraving machines, laser welding machines, laser code spraying machines, laser cutting machines, etc. They can accurately control the temperature required by the laser equipment, thereby ensuring the normal operation of the laser equipment. How can we eliminate the problem of low condensation pressure in the laser chiller?

The common reasons for low condensation pressure in laser chillers are as follows:
1. The surface of the condenser is too large;
2. The load on the evaporator is small;
3. The suction pressure is too low, such as insufficient liquid in the evaporator;
4. The suction and discharge valves of the compressor may leak;
5. The pressure setting of the condensation pressure regulating valve is too low;
6. The uninsulated receiver placed is too cold compared to the condenser (the receiver is used as a condenser);
7. The cooling air temperature is too low;
8. Excessive air volume in the condenser;
9. Excessive water volume (water cooling);
10. The water temperature is too low (water cooled).

Based on the above faults, we will troubleshoot them one by one using the following methods:
1. Adjust the condensation pressure or replace the condenser;
2. Adjust the condensation pressure;
3. Find the fault on the pipeline between the condenser and the thermal expansion valve;
4. Replace the compressor valve plate;
5. Set the correct pressure for the condensation pressure regulating valve;
6. Move the receiver or install a suitable insulation cover for the receiver;
7. Adjust the condensation pressure;
8. Replace the smaller fan or adjust the motor speed;
9. Reduce the flow of cooling water;
10. Increase the temperature of the cooling water.
