Precautions for use of vacuum pump on CNC Router machine

1.The vacuum pump needs to be filled with water first, open the water tank cover, add water to a position ten centimeters below the top of it, then connect the power supply, and turn it on after 15 minutes. If the pump is filled with water and turned on immediately, the water has not entered the pump body at this time, causing damage to the water seal.

2. The vacuum pump should be replenished with water before working every day. The water temperature should be controlled at ≤40°C. When CNC Router machine finishes engraving each board, the valve of it should be closed and another board should be added. Do not cut off the power supply of the vacuum pump. If the power supply of the vacuum pump is cut off , not closing the valve of CNC Router machine will cause the vacuum degree of the vacuum pump to become smaller.

3. The power switch of the vacuum pump is not lower than 100A. The power supply of the vacuum pump should be independent. It is not allowed to share a power switch with other equipment. If the motor speed is slow or the power switch trips, the power should be turned off in time to check whether the circuit is normal.

4. The water in the water tank should be replaced regularly, about once every two weeks, and the water tank cover should be opened to regularly remove the dirt in the water tank. If the water is not replaced regularly, the life of the pump body and impeller will be shortened, and the water seal will be damaged.
