As one of the core parts of the laser cutting machine, the importance of the laser is self-evident. We need to make a more detailed maintenance plan for it, according to the daily, weekly, monthly and its operation time.
1、 Daily maintenance of laser cutting machine
The laser should be maintained before starting every day.
1) Inspection of laser working gas and cutting gas: check the cylinder of laser working gas
2) Check that the cooling water pressure is kept between 3.5 and 5 Bar.
3) Check the temperature of cooling water, and the water temperature required by the selected laser is the best.
4) Check the oil level in the laser vacuum pump. If it is not enough, add it.
5) Check whether there is leakage in the oil, water and gas circuits of the laser, and whether there is leakage in the pneumatic components and pipe joints of the vacuum pump and resonator.
2、 Weekly maintenance of laser cutting machine laser
1) Check whether there is oil and water in the gas mixing unit of the laser, and if there is any, clean it in time; Check the laser gas drying filter. If more than 1/4 of the color turns red or white, replace it. Its normal color is blue.
2) Check the oil level of vacuum pump and Luozi pump. If it is not enough, add it.
3) Check the filter of the water cooler for impurities.
4) Check the cooling water circuit of the laser for impurities.
5) Check the condensate water level in the compressed air separator (located in the air supply unit). Check the vacuum pump oil level (under the air supply unit). When the pump is in the cold state, the oil level should be between+5mm and 0mm at the middle line of the oil window, and then refuel if necessary.
6) Check the oil level of roots pump. The oil level in the gear box of Roots pump can be seen through the oil window on the end face of the gear box. When the pump is turned off and in the cold state, the oil level should be between+5mm and 0mm of the middle line of the glass. If necessary, add HTCL2100 oil.
3、 Semi-annual maintenance of laser cutting machine laser (or after 2000 hours of operation)
1) Check whether the cooling water pipeline of the laser head is corroded, and if so, timely handle or replace the pipeline.
2) Check whether the excitation power tank leaks oil.
3) Check whether the high-voltage cable is damaged.
4) Check and clean the inside of the laser resonator and all lenses, including the front window mirror, tail mirror, reflector, etc.
5) After cleaning the internal lens of the laser, readjust the output mode of the laser until the correct mode is reached.
6) Replace the vacuum pump oil.
7) Replace the roots pump oil.
8) Carefully tighten all plugs to ensure the air tightness of roots pump.
9) There is a white plastic plug on the gas distributor at the outlet of the Roots pump. Clean the plug and coat the inner surface with silicone grease. The purpose of this silicone grease is to adsorb and capture the physical impurities in the circulating gas of the laser. (Only silicon free high vacuum grease can be used, which should be applied thinly).
