Key points for inspection and maintenance of cooling system of laser cutting machine

As an important equipment in modern industrial manufacturing, laser cutting machine has been widely used in many fields such as metal processing and advertising production due to its efficient and precise cutting ability. However, during the long-term operation of laser cutting machine, the stability and reliability of the cooling system are crucial to ensure the normal operation of the equipment and extend its service life. This article will introduce in detail the key points for inspection and maintenance of cooling system of laser cutting machine to help users better maintain the equipment and improve production efficiency.

1. Importance of cooling system

When the laser cutting machine is working, the high energy released by the laser beam will cause the internal temperature of the equipment to rise. If the heat cannot be dissipated in time, it will have a serious impact on the stability and service life of the equipment. As an important part of the laser cutting machine, the cooling system has the main function of taking away the heat inside the equipment through circulating coolant to ensure that the equipment operates within the normal temperature range. Therefore, regular inspection and maintenance of the cooling system is of great significance to ensure the normal operation of the laser cutting machine.

2. Key points for inspection of cooling system

‌Coolant level inspection‌

Regularly check the liquid level in the coolant tank to ensure that there is enough coolant. Too low a liquid level may result in poor cooling effect and affect the heat dissipation of the equipment.

‌Coolant quality inspection‌

Observe the color and transparency of the coolant. If there is turbidity, odor or sediment, the coolant should be replaced in time. Poor quality coolant may affect the cooling effect and the normal operation of the equipment.

‌Cooling pipe inspection‌

Check whether the cooling pipe is unobstructed and leak-free. Pipe blockage or leakage may cause the coolant to fail to circulate, affecting the heat dissipation effect.

‌Water pump operation inspection‌

Check the operating status of the water pump to ensure that the water pump can start and stop normally, and runs smoothly without abnormal noise. Water pump failure may cause the coolant to fail to circulate, affecting the cooling effect.

‌Radiator inspection‌

Check whether the radiator's heat sink is clean and unobstructed, and whether the fan is running normally. Radiator blockage or fan failure may cause poor heat dissipation and affect the heat dissipation of the equipment.

3. Key points for cooling system maintenance

‌Regularly replace the coolant‌

Regularly replace the coolant according to the requirements of the equipment instruction manual. Avoid using expired or deteriorated coolant to ensure the cooling effect and the normal operation of the equipment.

‌Cleaning cooling pipes‌

Clean cooling pipes regularly to remove impurities and sediments in the pipes to ensure smooth circulation of coolant.

‌Check and replace water pump seals‌

Check the status of water pump seals regularly. If there is wear or aging, replace them in time. Avoid seal leakage leading to coolant loss and affecting the cooling effect.

‌Clean radiator‌

Clean the radiator's heat sink and fan regularly to remove dust and debris to ensure good heat dissipation.

‌Check cooling system electrical components regularly‌

Check the connection status of cooling system electrical components regularly to ensure that the electrical components are connected reliably and without looseness. Avoid electrical failures that cause the cooling system to fail to operate normally.

4. Case analysis

During the use of a laser cutting machine, a user found that the device frequently alarmed that the temperature was too high. After inspection, it was found that the coolant in the cooling system had deteriorated and the radiator's heat sink was blocked by dust. After the user cleaned the cooling system and replaced the coolant according to the above maintenance points, the equipment resumed normal operation and the temperature alarm problem was solved.

V. Conclusion and Outlook

The stability and reliability of the cooling system of the laser cutting machine are crucial to ensure the normal operation of the equipment and extend its service life. By regularly inspecting and maintaining the cooling system, the failure and damage of the equipment caused by excessive temperature can be effectively avoided. In the future, with the continuous development and innovation of laser cutting technology, the cooling system will also be continuously optimized and upgraded to provide more efficient and reliable heat dissipation guarantee for the laser cutting machine. At the same time, users should also strengthen their awareness of daily maintenance and care of the equipment to improve the efficiency and life of the equipment.
