Water Cooling Laser: Abnormal Water Temperature

If the water temperature is abnormal, the equipment could be shut down or even damaged. This article describes the troubleshooting steps and solutions for high water temperature and cooling system failure, including sensor checks, filter cleaning, and parameter adjustments.

Why is it important to respond immediately to abnormal water temperatures?

The water cooling system of a laser machine is like its "heart." If the water temperature exceeds the limit, the precision of the machining will decline, and in serious cases the laser tube will be burned out.Friends who have encountered this situation know that the production lost due to the downtime is bad enough, but the repair costs are even worse.So we have to learn to find and fix problems ourselves before they become big problems.

We'll teach you step by step how to solve the problem of water temperature.

First, check to see if the temperature display is accurate.

Don't rush to take the machine apart. First check whether the temperature displayed on the control panel is correct.Take an infrared thermometer and measure the temperature of the water entering and leaving the tank. If the temperature is more than 3 ° C off from the displayed temperature, there's an 80 % chance that the sensor is clogged with scale or that the wiring is loose.At this point you can try soaking the probe in white vinegar, then reinserting it.

They also check to see if the waterways are clogged.

If the water tank feels hot, turn off the equipment and open the side panel to find the cooling water filter. Most filters are located beside the water pump.If you find that the filter is clogged with algae or rust, don't hesitate--change the filter.He also straightened out a kink in the pipe to insure smooth flow.

Don't slack off on the cooling fans.

The component most likely to cause problems in the summer is the cooling fan.If the fan cannot draw a piece of A4 paper close to the outlet, then the fan is too weak.First you clean the dust off the blades, and then you lubricate the bearings.If the fan is still slow, change it for a new one of the same model; don't be stingy with your money.

Daily maintenance can prevent problems before they arise.

Every month, take the time to drain the water tank and refill it with distilled water (never use tap water) and rust inhibitor.If the water temperature is too low in winter, you can add 10-15 % antifreeze to the water, which both prevents freezing and protects against corrosion.Remember to keep the water cooling system on even when the machine is not in use. Keeping the water temperature between 20 ° and 25 ° C will save on energy.

What about the difficult cases?

If the above methods don't work, the pump may be worn out or the circuit board may have a problem.At this point, listen for unusual noises and feel for vibrations. If there are any, it is probably time to replace the pump.Problems with the circuit board are more complicated, and I suggest that in that case you contact the manufacturer directly. Don't try to fix it yourself, or you might end up damaging the microchip and making the situation worse.
