As we all know, in the process of laser cutting machine work, it is often necessary to cool it with a supporting chiller to ensure that the laser cavity is not thermally deformed, the laser cutting machine's output power is stable and the beam quality is guaranteed, thereby improving the use of the laser Life and cutting accuracy. So, how does the chiller of the laser cutting machine work? What matters should be paid attention to in the installation and use of the chiller? Today Leapion Laser will share with you.
The working principle of the laser chiller is: first inject a certain amount of water into the stainless steel water tank in the chiller, and then cool the water through the chiller's refrigeration system (the refrigeration compressor uses the low-pressure and low-temperature refrigerant gas in the evaporator (refrigerant: R22) Suction cylinder
Then the compressor does work to make it a gas with higher pressure and temperature. It enters the condenser. The high-temperature and high-pressure refrigerant gas exchanges heat with the cooling medium and cooling air, and transfers the heat to the outside of the laser chiller for cooling. The agent gas is condensed into a high-pressure liquid) and then the low-temperature cooling water is sent to the laser equipment that needs cooling by the pressure of the water pump of the chiller;
At this time, the water chilled by the chiller will take away the heat in the laser machine, then the temperature will rise and then return to the water tank, and then go through the cooling cycle of the chiller to achieve cooling.
Why is the application of laser cutting machine inseparable from the chiller? Because it needs to cool down! It can be seen from the working principle of the chiller that the chiller is a kind of water cooling equipment that can provide constant temperature, constant current, and constant pressure cooling equipment.
1. The installer must have relevant professional knowledge (or have professional guidance);
2. After opening the package, first check whether the machine is in good condition and whether the accessories are complete;
3. Confirm whether the equipment is properly grounded. The ground where the chiller is installed must be a flat ground. Although the average operating current of the chiller is not large, its instantaneous operating current is sometimes as high as 6~10A;
4. The chiller of the laser cutting machine should be placed in a ventilated and constant temperature environment. If the temperature is too low in winter, antifreeze should be added;
5. At one end of the chiller, there should be a space for pipe extraction to clean the condenser tube bundle, and door openings or other suitable openings can also be used;
6. Choose a water pipe with a suitable pipe diameter, the cooling system and chilled water system when the chiller is running at maximum power, and connect them correctly;
7. Under any load conditions, the water flow should remain stable;
8. In order to reduce noise and vibration, it is best to install vibration isolators on the chiller pipeline;
9. Unscrew the water injection port of the machine and add cooling water. Note that only neutral and pure water or distilled water can be used, and no granular solids are allowed in the water;
10. To protect the circulating water pump, it is strictly forbidden to run without water! Please install a filter at the inlet of the water pipe of the chiller and clean it regularly;
11. After the leak test is completed, all the nozzles of the chiller must be treated with rust prevention;
12. Make sure that the air inlet and outlet channels of the chiller are smooth, and do not put foreign objects into the equipment!
13. Pay attention to the temperature of the chiller. When the water temperature is lower than the ambient temperature and the ambient humidity is high, condensed water will be generated on the surface of the circulating water pipe and the cooled device;
14. If there is a sudden abnormal situation, you should stop the operation of the machine first, cut off the power supply, and report the abnormal phenomenon to the professionals, and remember that you cannot continue to use it.
The chiller is an important part of the laser cutting machine. When using the laser cutting machine, we must strictly abide by the operating rules and precautions. The use and maintenance personnel must always pay attention to the condition of the chiller.
