The flow rate of the plunger pump is unstable
Thread Content
The plunger pumps we use are operated in three units connected together, with the aim of achieving stable flow rates. However, the flow rate remains unstable even now. The flow rate of the plunger pumps is controlled by the system; once a flow rate is set, it adjusts the reciprocation frequency based on the current stroke length. So my question is: with a fixed set flow rate, should the stroke length of the plunger pumps be increased or decreased to achieve a more stable flow rate? What principle
The flow rate of a plunger pump is inherently unstable and exhibits pulsating characteristics; therefore, an accumulator (a small storage tank) should be used to stabilize the flow rate.
A three-cylinder single-acting plunger pump, equipped with an outlet buffer, ensures more stable outlet flow.
Since the current is unstable, the pump flow rate will also be unstable. A high-level tank can be added to maintain material reflux. Then the material flow coming down from the high-level tank became more stable
