Piston pump (piston pump, plunger pump) are positive displacement pumps, reciprocating pumps. Pressure piston is reciprocated by the plunger in the plunger cylinder piston in the cylinder caused by a change in the sealed volume difference resulting from the fluid medium leaving work. Changes in the working stroke of the plunger can control the size of the piston flow. Hydraulic and pneumatic drive piston is an important working parts. Into common piston radial piston hydraulic motor (import agent), axial piston pump. Also called a positive displacement gear pump means, i.e., like a piston inside the cylinder, when one of the teeth into the fluid space of another tooth, the liquid was squeezed mechanically discharged. Because the liquid is incompressible, so the liquid and the teeth can not occupy the same space at the same time, so that the hydraulic motor (import finishing), the liquid was removed. Due to the continuous engagement of the teeth, this phenomenon occurs continuously and, therefore, at the outlet of the pump provides a continuous exclusion amount of the hydraulic motor (import care), per revolution of the pump, the discharge amount is the same. With the continuous rotation of the drive shaft, the pump will discharge fluid continuously. Pump flow and pump speed directly related.
