6.2 Maintenance of water cooler
The main function of the water cooler is to cool the laser and welding head, so that the laser and welding
head can maintain in a constant temperature working condition. Therefore, proper and regular
maintenance is the key to ensure the normal work of the machine. At the same time, the circulating water
of the water cooler must use distilled water. Due to the water quality problems, there are still certain
minerals, dust and other impurities in the circulating water, and the dust in the environment may also enter
the circulating water in some operation links. The deposition of these impurities can lead to the blockage
of water systems (such as metal filter, welding head, laser, QBH), which can seriously affect the welding
results or even burn out the optical components. The accumulation of dust and other debris in the
environment on the radiator and water pump of water cooler will lead to poor heat dissipation, resulting in
poor cooling, burned compressor, or burned water pump, which will also directly affect the welding results
or cause the machine not to work. Therefore, the daily maintenance of the water cooler is particularly
important.
Please refer to the maintenance instructions for water cooler and regularly maintain the cooling system of
the laser welder (cleaning machine).
Maintenance of water cooler:
1. Check whether the temperature setting of the water
cooler is normal (set temperature: 25±1℃).
Ensure that the temperature of the
cooling water supplied to the laser
is normal.
2. Check whether the water circuit seal, water
temperature and water pressure of the water cooler
meet the requirements.
Ensure proper operation of the
equipment and prevent water
leakage.
3. Keep the working environment of the water cooler
dry, clean and ventilated.
Contribute to the proper operation
of the water cooler.
1. Remove the dirt on the surface of the water cooler
with neutral cleaner or high quality soap. Do not clean
the system with benzene, acid, abrasive powder, steel
brush, or hot water.
Ensure that the surface of the
water cooler is clean.
2. Check whether the condenser is blocked by dirt.
Please use compressed air or brush to remove the dust
from the condenser.
Ensure the normal operation of the
condenser.
