Who knows how to drain the high-power laser cutting machine and how to add antifreeze

I. Drainage method of laser cutting machine

The main drainage parts of water cooler and water tank for laser cutting machine : water tank, pipeline, pump head, filter, deionization tank (optional accessory)

1. Disconnect the power supply of the equipment involved in drainage.

2. Water tank drainage method: Open the drain valve (or drain plug) at the bottom of the water tank to drain the water from the water tank. If necessary, you can tilt the water cooler to a certain angle to make the drainage more clean.

3. Drainage in pipelines and lasers: Unplug the four-way water pipes first, and then use compressed air to blow from the pipeline drainage inlets and outlets for 1 minute respectively to force the water stored in the pipelines back to the water tank and drain the water from the water tank's drain port.

4. Unscrew the filter element in the refrigerator and drain the water in the filter element.

5. Open the water tank cover and observe whether there is still water left in the water tank (you can use compressed air to connect the water port to blow back again, and force the residual water in the pipeline, laser (tube), and pump to return to the water tank, and then discharge it from the water tank drain port) If available, tilt the chiller slightly to allow the water to drain or dry it with a dry towel.

6. Drain the pump head: Unscrew the drain screw under the pump to drain the water in the pump. It is recommended to blow out the residual water on the pump head with compressed air, and then tighten the drain screw.

7. Drainage of filter and deionization tank: Open the filter, the drain valve at the lower part of the deionization tank or the plexiglass shell to remove the residual water.

Conditions and methods for adding antifreeze to cooling water

1. Antifreeze glycol (also known as glycol) can be purchased at your local hardware and chemical store. It is also available online, but there are restrictions on liquid transportation.

2. The ratio with deionized water is about 30% lower, and 50% is recommended, (70% for water and 30% for ethylene glycol).

3. Be sure to add the ambient temperature below zero (inclusive).

4. Ethylene glycol is not equal to ethanol (alcohol), please distinguish it.
