How to protect laser source in winter
In the cold winter, when the air temperature is lower than 0 °C, the
liquid water will condense to form a solid, and in the process of
solidification, the volume will become larger; this will "crack" the
pipelines and components in the water-cooled system ( The chilled water
system includes a chiller, a laser, and an output head). During the
installation and commissioning of your company, please pay attention to
the antifreeze before using it. After the commissioning is completed, the
QBH output cable and laser must be filled with antifreeze and stored or
sent to the customer to avoid loss caused by freezing damage during
storage and transportation.
How to avoid laser antifreeze on the client is a key issue in winter laser
maintenance. We will inform you about the use of laser antifreeze
protection measures and hazards in winter, and please remind your
customers again to avoid losses.
一. If there is no power outage in the local area, the water cooler will not
be turned off at night, and at the same time, energy saving, low
temperature and normal temperature water temperature will be
adjusted to 5 ~ 10 °C, to ensure that the coolant is in a circulating state
and the temperature is not lower than the freezing point.
二．Use antifreeze as coolant
Antifreeze must be used when the environment is often blacked out and济南新天科技有限公司
there are no conditions for daily coolant venting. The base liquid of
antifreeze is generally composed of alcohol and water. It requires high
boiling point and flash point, large specific heat and conductivity, low
viscosity at low temperature, not easy to foam, and does not corrode
metal parts and rubber hoses. When selecting or blending antifreeze, the
freezing point should be 5 °C lower than the lowest temperature in the
Add professional brand antifreeze to the water cooler, such as Clariant's
AntifrogenN antifreeze, which is added in a ratio of 3:7 (3 for antifreeze,
7 for water), and can resist -20 ° C without freezing after adding
antifreeze. If the temperature is lower than this range, please consult the
water cooler supplier to confirm the proportion of antifreeze.
If the professional brand is not convenient to buy, you can purchase the
large-capacity car antifreeze shell OAT-45°C, which can be directly used
in the laser water cooling system. The dilution ratio can refer to the
following table. Please compare the actual temperature according to the
place of use, due to the use environment and water cooling machine.
The reason for the configuration, the actual use will affect the flow rate
and flow rate of the coolant, causing the water cooler flow alarm or the
laser heat dissipation problem. If the temperature is abnormal, please
contact our company after-sales personnel.济南新天科技有限公司
2. Antifreeze use precautions
Any antifreeze cannot completely replace deionized water and cannot be
used for a long time throughout the year. After the winter, the pipeline
must be cleaned with deionized water or purified water, and deionized
water or purified water should be used as a coolant.
At the same time, during the holidays such as the Spring Festival holiday
or during the long power outage, please drain the water in the pipeline
related to the laser and water cooler.
3. If is fine ,it is better for water chiller working continuously.
4. If your laser machine did not use for long time ,please drain the water
chiller,cutting head,and laser source out ,do not leave water inside
