Today, Du Fu Instrument will briefly introduce the maintenance knowledge of circulating water vacuum pump for you. Regularly maintaining clean water quality is the key to the long-term stable operation of equipment. It is necessary to regularly change and clean the water tank. Cannot extract dust and solid substances.

1. Certain corrosive gases can cause the water quality in the water tank to deteriorate, generate bubbles, and affect the vacuum degree, so attention should be paid to continuously circulating and changing the water.

2. For special highly corrosive gases, it is necessary to carefully determine whether they react with the materials used in this equipment and use them with caution.

3. If the vacuum level cannot be increased, the first step should be to determine whether the container is leaking or the hose is loose. If it is a problem with the pump, check whether the inlet or each air path is blocked or loose, and whether there is air leakage.

4. If the motor of the circulating water vacuum pump is not running, the power supply or fuse should be checked.
