How to solve the lack of suction of woodworking engraving machine platform

In the use of the woodworking engraving machine, there may be a phenomenon that the adsorption table has no suction and cannot absorb the board. What is the reason for this and how should it be solved? Now I will introduce the solution to the non-adsorption of cnc machine wood working table:

1. Whether the motor line voltage is normal;

2. Whether the water circulating air pump adds less water, and whether the motor is stuck and rusted. Remove the rotating shaft center of the motor fan protection net;

3. Clean up the filter blockage in the vacuum pump;

4. Repair the countertop or pipeline with air leakage;

5. On the forward and reverse rotation of the motor, any two wires change the direction of the motor.

The wood machine adopts vacuum adsorption to fix the board, which can not only be firmly fixed, and will not move and engrave dislocation, etc., but also fixed relative to the splint, which can save the board and carve to the edge of the board, saving time and effort.
