Description

Technical Field

[0001] The utility model relates to the technical field of laser cleaning machines, in particular to active water supply equipment for laser cleaning machines. Background Art

[0002] Laser cleaning has the characteristics of no grinding, no contact, no heat effect and is suitable for objects of various materials. It is considered to be the most reliable and effective solution. Laser cleaning machine is a laser emitting device used for laser cleaning.

[0003] The main function of the laser chiller is to provide water circulation cooling for the laser generator of the laser equipment and accurately control the operating temperature of the laser generator so that the laser generator can maintain normal operation for a long time. During the operation of the chiller, we can first inject a certain amount of water into the internal water tank of the machine, cool the water through the chiller refrigeration system, and then use the water pump to inject low-temperature frozen water into the equipment that needs to be cooled. The frozen water takes away the heat inside the machine and returns the high-temperature hot water to the water tank for cooling. In this way, the cooling cycle is exchanged to achieve the purpose of cooling the equipment.

[0004] At present, when the laser cleaning machine is in use, the cooling water in the chiller will continue to decrease as the cooling is circulated and exchanged. Although the cooling water in the chiller will sound an alarm after it drops to the warning line to remind you to add water in time, the above operation is still relatively troublesome and requires stopping the machine to add water, which affects the processing speed.
