How To Exhaust Air From Pipeline Centrifugal Pump

Feb 13, 2021

Pipeline centrifugal pump is currently one of the main mechanical equipment for water pumping and transportation. If there is a large amount of air in the pump body due to abnormal operation, it will affect the normal operation of the equipment. Then, how does the pipeline centrifugal pump exhaust air? Most types of pipeline pumps have self-exhaust function, in addition to manual operation of exhaust.

Pipeline centrifugal pumps are easy to install and operate. Because of their excellent water treatment capabilities, they are currently widely used in long-distance water transportation, pressurized water transportation, and HVAC refrigeration cycles. During use, if there is air in the pump body, it will cause abnormal noise and abnormal jitter, and occasionally affect the stability of the flow rate, making it impossible to meet the water transportation requirements. For this, it is necessary to clarify how the pipeline centrifugal pump discharges air. Restore equipment stability.

Before understanding how to exhaust air in a pipeline centrifugal pump, the first thing to know is that the reason why there is air in the pump body is usually due to leakage of the inner wall of the pipeline or poor sealing. After removing the specific cause, perform air removal and operation. Methods as below.

1. Some models of pipeline pumps and centrifugal pumps are equipped with exhaust valves, which can be activated directly;

2. Use the method of circulating water to discharge the gas, first suck the water from the reservoir, and then transport the water back to the pool, repeat the operation;

3. Exhaust gas through low-in and high-out water transportation;

4. Exhaust gas through the gas outlet pressure gauge.
