Piston pump displacement

Piston pump displacement

[Abstract]:
Everyone must pay attention to the displacement of the axial piston pump when purchasing the axial piston pump. Many people regard the displacement of the axial piston pump as the condition for purchase. Sometimes, the displacement of the axial piston pump needs to be calculated by ourselves. At this time, if you don't understand the calculation method and formula, then you can't start it. The so-called clever woman is difficult to be without rice. Here we will tell you how the displacement of the axial piston pump is calculated.
Everyone must pay attention to the displacement of the axial piston pump when purchasing the axial piston pump. Many people regard the displacement of the axial piston pump as the condition for purchase. Sometimes, the displacement of the axial piston pump needs to be calculated by ourselves. At this time, if you don't understand the calculation method and formula, then you can't start it. The so-called clever woman is difficult to be without rice. Here we will tell you how the displacement of the axial piston pump is calculated.
 
Compared with the displacement of the axial piston pump and the flowmeter, the diameter of the plunger is d, the diameter of the plunger is D, and the inclination of the swash plate is γ, the stroke of the plunger is s=Dtanγ, so when the number of plungers is z, the displacement of the axial piston pump is:
 
V=πd2Dtanγz/4
 
Let the pump's number of revolutions be n, and the volumetric efficiency be ηv, then the actual output flow of the pump is:
 
V=πd2Dtanγz nηv/4
 
In fact, since the speed at which the plunger moves in the cylinder bore is not constant, the output flow is pulsating. When the number of plungers is odd, the pulsation is small, and the number of plungers is small, so The number of plungers of a commonly used plunger pump is 7, 9, or 11.
 
Seeing here, everyone should know how to calculate the displacement of the axial piston pump. In the future, whether it is in production or purchase, you can calculate it at any time.
