The acid resistant submersible pump has the advantages of compact structure, convenient operation, stable operation, easy maintenance, high efficiency and long life. It also has a self-priming function. There is no need to install a bottom valve in the pipeline, and it is only necessary to ensure that there is a certain amount of storage in the pump before work. The drainage can have the function of "one-time drainage, life-long self-priming". Therefore, the piping system is simplified and the working conditions are improved.

The acid resistant submersible pump has been recognized by the majority of users, but the acid resistant submersible pump must be well maintained to make the mechanical flexibility and work efficiency as good as possible. What are the maintenance measures for the acid resistant submersible pump?

1. Check the self-priming pump pipeline and joints for looseness. Rotate the self-priming pump by hand or tool to see if the self-priming pump is flexible;

2. Try to control the flow rate and head of the self-priming pump within the range indicated on the sign to ensure that the self-priming pump operates at a higher rate, so as to obtain a greater energy-saving effect;

3. During the operation of the self-priming pump, the bearing temperature should not exceed the ambient temperature of 35C, and the higher temperature should not exceed 80C;

4. If the self-priming pump is found to have abnormal sound, stop immediately to check the cause;

5. When the self-priming centrifugal pump is to be stopped, first close the gate valve and pressure gauge, and then stop the motor;

6. When the high-suction self-priming pump is not used for a long time and is used in cold winter, after parking, it is necessary to unscrew the drain plug at the bottom of the pump body to drain the medium. Prevent freeze cracking. (If it is sewage, please clean the pump cavity with clean water).

The above is the correct maintenance method of acid resistant submersible pump. In the process of use, it is particularly important to develop regular maintenance methods, which can not only make full use of its value, but also prolong the service life of the equipment.
