a) The laser source cooling water connection is shown in Figure 10, 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 cooling water circuit water pipe should be greater than
6.5N
·
m,and the tightening torque of the clamps for the normal temperature water circuit should
be greater than 5N
·
m.
