The Maintenance of the Water-cooled Part.
replacement period is 10-15 days, in which the NAion of the water quality must be less than 20, for example, the customer chooses inferior water, or the cooling The foreign body of water causes blockage to the optical path. The customer will bear the relevant costs at his own expense.
continues to be higher than 30°, it is recommended to set the temperature to 28°. In order to perform laser cutting operation, high temperature startup or all damage caused by the operation process To bear. The laser temperature range is 18° to 28°, do not exceed 29°.
(3)The temperature of the cooling water must match the ambient temperature within 10°,if the matching
temperature is not adjusted in time.Due to the degree of condensation caused by the light path or the laser,
the customer will bear the costs related to lens maintenance and lens condensation damage.Remember!!!
(4)The replacement cycle of related consumables is 200 hours. Please replace the filter cartridge in time to
avoid contaminating impurities.
Circuit Section Maintenance
Relevant electrical components and electrical control cabinets are blown once with oxygen for 3 days. The
maintenance period of the IPC must be cleaned within 15 days.All side doors of the power control cabinet
are opened, and dust is cleaned with oxygen every day. For those who have air-conditioning, please close
the electrical control cabinet. Users who do not install air conditioners can use the fan to align the inside of
the power box for high-temperature heat reduction. Conditional customers can build air-conditioned room
to reduce heat. If the necessary heat insulation treatment is not performed according to the manufacturer's
requirements, the electrical components are damaged. The customer will bear the relevant costs.
Attachment: In this issue we will introduce the use of medium-power lasers to prevent condensation in the summer.
The breakdown of the laser inside the severe condensation is as follows:
Defects due to condensation are not covered by the normal warranty. Under normal circumstances, the
effect of condensation on the laser requires a certain process. There are some easy-to-find symptoms in the early stage of internal dew condensation. For example, the surface of external exposed cooling water pipes will usually show condensation first, and will only spread to the inside of the laser after some time.
Lasers have been designed with the necessary moisture protection, but they cannot 100% avoid the effects
of excessive condensation.Since condensation is an objective physical phenomenon,the method of
avoiding condensation usually starts from two aspects:
1. The water temperature is set above the condensation temperature, but it must meet the laser cooling requirements. This method has certain limitations.
2. Change the temperature and/or humidity of the laser operating environment to keep the water temperature away from the dew point temperature (recommended).
Note: When the laser is turned off, the water cooler should also be turned off to prevent condensation due to shutdown due to excessive temperature difference. If the cabinet is designed with air conditioning, it is recommended that the air conditioner be turned on for half an hour before turning on the water cooler.And laser source power supply.
About Condensation
In fact, condensation is not a phenomenon unique to lasers,but an objective physical phenomenon. In our daily life, it is easy to see this physical phenomenon, especially the hot summer, such as: in the south, the wall inside the house will appear similar to the "sweat" phenomenon; water pipes at home or in public areas The outer wall and so on.
Therefore,for water-cooled lasers, there is virtually no direct relationship between condensation and light emission.
That is, even when the power of the laser is turned off, when the temperature of the housing is low (for example, the cooling water is not turned off), if the temperature and humidity of the environment reaches a certain level, condensation will occur as well.
The following measures can effectively reduce the probability and risk of condensation, which can be considered as appropriate:
1. If the cooling capacity and flow of the water cooler are adequately redundant, the water temperature can be increased by about 1-2°C as appropriate.
2. The external light path (QBH interface) cooling requirements for water temperature is relatively more relaxed, and it is appropriate to properly exceed the dew point.
When the equipment is deactivated, the laser should be disconnected from the AC power and the water cooler should also be turned off.
Recommendation: Summer, high temperature water (cutting head) 30`C low temperature water (laser) 28`C/Winter, high temperature water (cutting head) 20`C low temperature water (laser) 18`C
