Pay attention to these when using laser cutting equipment in low temperature area

In the low temperature area, laser cutting machine is facing the test of extreme cold. If it is not operated properly, it will only affect the normal operation of the equipment and reduce the production progress; if it is operated improperly, it will damage the laser cutting machine and the water chiller inside, causing unnecessary property loss to customers. So when using laser cutting machine in low temperature area, we should pay attention to the following three points:

1. When using the laser cutting machine, we should drain the water first to ensure the normal operation of the equipment. First, after disconnecting the water pipe, we use about 5bar of compressed air or nitrogen to blow water at the water inlet and outlet for about one minute to drain the internal water in the laser machine.

2. The ambient temperature of the water chiller in the cutting machine is required to be higher than 0 ℃, mainly to prevent the water in the water system from freezing once the water chiller in the cutting machine stops using due to the low ambient temperature, especially in the north, which will affect the normal use of the equipment, and even damage the whole refrigeration system if it is serious.

3. After starting the cooling water pump and normal temperature water pump of the water chiller in the cutter, check the readings in the cooling water pressure gauge and normal temperature water pressure gauge first. If the pressure or flow alarm occurs, it is necessary to pay attention to whether the valve of the water system is not opened or there is the possibility of freezing, and timely judge and handle. If it is determined that the water is frozen, the manufacturer must be informed in time for collaborative treatment! In addition, after the normal operation of the water pump, if the water temperature of the cooling water is lower than the minimum temperature allowed for the laser cutting machine to start up, in the case of no temperature rise for a long time, the set temperature of the cooling water and the normal temperature water can be set at 5 ℃ higher to ensure the normal operation of the equipment.leapion
