Requirements on cooling water:
a) The laser source cooling water connection is shown in Figure 11, and the arrow direction
indicates the water flow direction;
b) Cooling water needs to use pure water;
c) In order to prevent the water in the water cooler from growing mold and causing pipeline
blockage, it is recommended to add alcohol when filling pure water, and the amount of alcohol
added is 10% of pure water;
d) If ambient temperature is between -10℃ and 0℃, must be used to use 30% alcohol (volume
ratio), and replace it every 2 months;
e) If ambient temperature is below -10℃, the chiller with both heating and cooling functions must
be used, and keep it in full-time operation;
f) For the connection of cooling water and normal temperature water circuits,please use Raycus
supporting water pipes. If the water pipes are self-distributed,please do not increase the length
of the water pipes and change the inner diameter of the water pipes;
g) The tightening torque of the clamps for the 20000W laser cooling water circuit water pipe
should be greater than 6.5N·m. The tightening torque of the clamps should be greater than
5N·m for the normal temperature water circuit and cooling water circuit pipe with power of
15000W and below.
