When purchasing an axial piston pump, everyone must have also paid attention to the displacement of the axial piston pump. Many people consider the displacement of the axial piston pump as a condition for whether to purchase it. Sometimes, the displacement of an axial piston pump needs to be calculated by ourselves. At this time, if you don't understand the calculation method and formula, you won't be able to start. As the saying goes, a clever woman cannot cook without rice. In order to help everyone, here we will introduce how the displacement of an axial piston pump is calculated.

 

When calculating the displacement and flow rate of an axial piston pump, the diameter of the plunger is d, the diameter of the diffuser circle of the plunger is D, and the inclination angle of the inclined plate is γ, the stroke of the plunger is s=Dtan γ. Therefore, when the number of plungers is z, the displacement of the axial piston pump is:

 

V=πd2Dtanγz/4

 

Assuming the pump speed is n and the volumetric efficiency is η v, the actual output flow rate of the pump is:

 

V=πd2Dtanγz nηv/4

 

In fact, due to the fact that the speed of the plunger moving in the cylinder bore is not constant, the output flow rate is pulsating. When the number of plungers is odd, the pulsation is small, and when the number of plungers is large, the pulsation is also small. Therefore, the commonly used number of plungers for plunger pumps is 7, 9, or 11.

 

By now, everyone should know how to calculate the displacement of axial piston pumps. In the future, whether in production or purchase, everyone can calculate it at any time.
