Industrial laser chiller summer common failures and solutions

Nowadays, with the continuous breakthroughs in laser technology, the application of laser equipment is becoming more and more common, and the supporting peripheral equipment for lasers is also in greater demand. As a professional laser chiller manufacturer, Kuling Times today to talk to you briefly about the laser chiller in the process of daily use of one of the common failure problems, when our laser chiller encountered high and low voltage alarm, how to respond?

Laser chiller high and low voltage fault analysis and solutions.

A, high voltage alarm cause analysis

1, the cooling water is not open.

Solution: Please open the water valve.

2, the cooling water flow is too small or the temperature is too high.

Solution: Increase the flow of cooling water or reduce the water temperature.

3, condenser copper tube scale accumulation, small diameter, poor heat dissipation.

Solution: Clean the condenser copper tube.

4, too much refrigerant.

Solution: discharge excess refrigerant

5, expansion valve open too large.

Solution: appropriate to reduce the expansion valve open degree, the compressor thermal relay protection switch (RESTET) press, identify the cause of the reboot.

Second, the low pressure alarm cause analysis

1、Insufficient refrigerant.

Solution: leak detection, pipeline joints, whether there is a leak point? Refrigerant replenishment after repair.

2, the filter is blocked.

Solution: disassemble and clean or replace the filter.

3, condenser copper tube scale accumulation, small diameter, poor heat dissipation.

Solution: Clean the condenser copper tube.

4, the expansion valve is too small to open.

Solution: Properly reduce the expansion valve opening degree, after the exclusion of high and low pressure protection automatically reset.

The content described above is the common laser chiller high and low pressure fault analysis and solutions. We can see from the above analysis, when the laser chiller has a high pressure or low pressure protection alarm problem, our first task is to find the cause, and then according to the different causes of failure to do the corresponding treatment to ensure that the laser chiller can be safe and normal operation!
