CNC Router Water Vacuum Pump User Guide Manual and Troubleshooting

Vacuum pump is working together with vacuum table of cnc router. The both form the job holding system of cnc router machine. If you have questions on how to use the water ring cnc router vacuum pump properly and how to do troubleshooting for it, please do not worry, you will get all the answers from here. We (EagleTec) are experienced china cnc router manufacturer.

 

 

The cnc router water vacuum pump includes the following parts: pump, water tank, base, filter and check valve. Please see the following picture for display of each part of water ring type cnc router vacuum pump.

CNC Router Water Ring Type Vacuum Pump User Guide Manual:

Reminder: Please check there is water inside the water ring vacuum pump before you run it. And the water level should be higher than the vacuum pump motor shaft!

1. The inlet port (air inlet) is connected with the cnc router vacuum hose, do good sealing, prevent leakage.

2. Before the first time to start the water vacuum pump motor, please use a screwdriver to move the electric motor fan impeller, ensure the impeller moves smooth and there is no resistance.

3. Power on the water ring vacuum pump and adjust the rotating direction of vacuum motor is in accordance with the arrow indicator on the vacuum pump. Please refer to the picture below.

4. Fill the tank with water until the water come out from the upper water valve. (Please make sure that the upper water valve is open)

5. Open the valve for injecting water into pump (water inlet valve) and wait three minutes to ensure that the work fluid (water) flows into the pump cavity.

6. Start the water ring vacuum motor, water ring cnc router vacuum pump began to work, the table begins to adsorb.

 

CNC router water ring vacuum pump frequently asked questions and troubleshooting:

Question 1. Vacuum pump does not adsorb

Solution: The working fluid (water) does not enter the pump cavity, resulting in no water rings; or there is leakage in vacuum hoses.

 

Question 2. The vacuum motor does not turn when the first time to start vacuum pump.

Solution: As the impeller and disc clearance is very small and the iron parts itself is easy to get oxidation, leading to the impeller stuck phenomenon. In this case, we have to open the fan shroud at the rear of motor, knock the rear shaft head of motor with a hammer lightly, then turn the fan impeller by hand; if it can be moved, then install the fan cover back and start the motor.

 

Question 3. The suction of cnc router water vacuum pump is insufficient

Solution: The main reasons are: first, there is not enough working fluid (water) in the pump cavity, please check the inlet pipeline (water inlet); second, there is leakage in air inlet pipeline, please check the sealing performance of the air inlet line; third, long time without changing the working fluid (water), a lot of sawdust fall into the working fluid, reduced the quality of working fluid, so we must change the water regularly and keep it clean all the time.
