In winter, many new customers do not know how to prevent the laser equipment from freezing? Today, HANS GS shares the anti freeze measures for the fiber laser cutting machine.
In recent years, the use of optical fiber laser cutting machine is quite wide, so the anti freezing measures of the optical fiber laser cutting machine need to be paid more attention. Only by being familiar with the technique of antifreeze, this can better protect the core components of the laser equipment and make the laser equipment run better.
LASER SOURCE
I. It is suitable for frequent use and continuous operation of fiber laser source.
Recommended: Clariant industrial grade Clariant antifreeze (type: Antifrogen N, glycol water, industrial supplies, toxic to the human body). The volume of the tank is 10% -20%, not more than 20%.
II. It is suitable for fiber laser without continuous operation.
The medium power laser only needs to keep the chiller running at night. No power is needed. The 24V of the high power laser (maximum power is above 2000W) remains open, ensuring that the coolant is in circulation and the temperature is no less than freezing point.

CHILLING MACHINE

In the installation of air-conditioning or heating facilities, the environment temperature is maintained at 10 degrees celsius.

24 - hour operation of the refrigerator, the water does not freeze in the flow of the body under.

Adding ethylene glycol antifreeze antifreeze in the tank, the ice with the concentration of ethylene glycol in aqueous solution and the change in the.

- when the fiber laser cutting machine is not used for a long time or power failure, must be drained out of the water in the water tank refrigeration machine.

Drainage method

A, Turn off the power supply, open the drain valve behind the refrigerator and emptying the water in the tank.

B, Unscrewing the filter core in the refrigerator and emptying the water in the filter core.

C, Unscrewing the drainage screws under the pump, emptying the water in the pump.

D, Pull out the water pipe behind the water tank and mark it well. 0.2MPA (2KG) gas is used to get a section of the water pipe (12), emptying the water in the laser.

E, Use the gas of 0.2MPA (2KG) to receive the end of the pipe (8), emptying the water in the laser head.

PAY ATTENTION TO
For gas pressure drainage too easy to damage the laser. The high concentration of antifreeze solution increases the resistance of water circulation.
Must be of laser, laser output head, processing head and chiller all cooling water discharged to effectively protect the whole water cooling pipeline and related devices!
The method of adding antifreeze
A. Name: ethylene glycol, in the local hardware and chemical shop can be purchased, online also, but the liquid can not be transported.
B. The proportion is about 30%, (water 70%, ethylene glycol 30%).
C. 0 degrees (containing) must be added.
D. Glycol is not equal to ethanol (alcohol). Be sure to make a strict distinction.
E. the full name of the purchase is: antifreeze glycol.
