User Guide of RFL-C20000M-CE
Water cooling requirements for output optical cables:
a) Water flow requirements: QP output cable water flow is greater than 3.0L/min;
b)Water cooling pressure: 0.4
～
0.6Mpa at the water inlet;
c) Water inlet and outlet connector type: M6 to ϕ8 quick-tightening connector;
d)Water pipe type: outer diameter ϕ8 and inner diameter ϕ5.5;
e) Cooling water quality: deionized water, distilled water, purified water;it is recommend to replace
once a month,and the replacement period should not exceed two months.
f)PH value of cooling water: 5.0
～
8.0;
g)The water cooler needs to be equipped with a filter element whose filter particle size is less than
100um;the filter element needs to be cleaned once a month.
h)Maximum cooling water temperature: 35
℃
;
i)The lowest cooling water temperature: 5
℃
greater than the saturated dew point temperature;
j)Additives in cooling water: meet the above PH value and solid particle size requirements;
k)Armored pipe bending radius: in non-working conditions such as transportation and storage, the
minimum bending diameter shall not be less than30cm. When the laser is emitting, the minimum
bending diameter shall not be less than 40cm;
l) Long-term vibration, less than 2G; impact, less than 10G.
Other requirements:
a) When starting the cooling system for the first time, check the entire water system and joint for
water leakage.
b)If the laser is not used for a long time, the cooling water inside the cooling system and the laser
inside should be drained, otherwise the laser equipment will be damaged.
c) Please use compressed gas below 0.5MPa when emptying water from the device. Failure to do so
may cause permanent equipment damage to cooling system.
CAUTION:
(1) Set the water temperature of the cooling system correctly according to the ambient
temperature. Setting the water temperature too high will result in the laser not working
properly. Setting the water temperature too low will cause condensation inside the laser or the
laser output head, which will cause damage to the laser;
(2) Before turning on the laser, the cooling system must be working properly and the water
temperature should be suitable for the temperature.
