As one of the core components of the laser cutting machine, the importance of laser is self-evident. We need to develop a more detailed maintenance plan according to the weekly, monthly and operating time of each day.
1. Daily maintenance of laser cutting machine The laser should be maintained before starting every day.
1) Check laser working gas and cutting gas: check the cylinder of laser working gas
2) Check whether the cooling water pressure is maintained between 3.5 and 5 bar.
3) Check the temperature of the cooling water. The water temperature required by the selected laser is preferred.
4) Check the height of the oil level in the laser vacuum pump. If it is not enough, add it.
5) Check whether the oil, water and gas circuits of the laser are leaking, and whether the pneumatic components and pipe joints of the vacuum pump and resonator are leaking.
2. Weekly maintenance of laser cutting machine
1) Check whether there is oil and water in the gas mixing unit of the laser, and if there is, clean it in time; Check the gas drying filter of the laser. If more than 1/4 of the color changes to red or white, replace it, and its normal color is blue.
2) Check the oil level of the vacuum pump and the roller pump, if not enough, please add.
3) Check whether there are impurities in the filter of the water cooler.
4) Check whether there are impurities in the cooling water circuit of the laser.
5) Check the condensate 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 cold, the oil level in the center line of the oil window should be+5mm-0mm, and add oil when necessary.
6) Check the oil level of roots pump. The oil level in the Roots pump gearbox can be seen through the oil window on the end face of the gearbox. When the pump is shut down and kept cold, the oil level should be within+5mm-0mm of the glass centerline, and add htcl2100 oil model if necessary.
3. The laser cutting machine shall be maintained every half a year (or after 2000 hours of operation)
1) Check whether the cooling water pipe of the laser head is corroded. If so, please handle or replace the pipe in time.
2) Check the oil tank of excitation power supply for oil leakage.
3) Check whether the high-voltage cable is damaged.
4) Check and clean the interior of the laser resonator and all lenses, including the front window mirror, rear view mirror, reflector, etc.
5) After cleaning the lens inside the laser, readjust the output mode of the laser until the correct mode is reached.
6) Replace the vacuum pump oil.
7) Replace roots pump oil.
8) Carefully tighten all plugs to ensure tightness of Roots pump.
9) There is a white plastic plug on the gas transfer drain at the outlet of Roots pump. Clean the plug and coat its inner surface with silicone grease. The purpose of silicone grease is to absorb and capture the physical impurities in the laser circulating gas. (Only silicon free high vacuum grease can be used, which should be very thin.)
