Tips: How to adjust the electromagnetic diaphragm pump?

Output pipeline installation loop method

We can add bypass loop in the output pipeline system, and then adjust the bypass valve to control the reflux, so that the system output can be adjusted to control the flow, both convenient and fast. But it has the disadvantage of increasing energy consumption.

Change the pump speed method

Change the pump speed to adjust the flow is also a common method, if the average flow of the pump and the pump speed value is proportional to the value, then change the pump speed to adjust the flow is the most effective method, the characteristics of the reciprocating pump is such. At the same time, we also need to change the pump speed to adjust the flow value of the device or the motor.

Adjust the length of the piston

As a common method, adjusting the piston, is the most common and effective method, we can adjust the piston stroke length to adjust the flow, its advantage is to meet the linear requirements in the case of small flow.
