- Working principle of hydraulic Piston pump

- A hydraulic piston pump is a circulating pump that moves and pressurizes fluids by using one or more return pistons. It is usually driven by an electric motor via a crankshaft and connecting rod.There are 2 types of piston pumps that we often encounter: lift pump and force pump, both of which can be controlled manually or by themselves moving.

- Like most hydraulic pumps they operate by using the force of the base pump mechanism to expand and contract a moving volume in the liquid.

- The hydraulic piston pump can also be operated single or double. Double acting pump delivers two sets of check valves and fluid on both sides of the piston, this allows the piston to complete the pump's full cycle by moving in one direction.

- So the pump works by moving into the cavity, so compressing the facilities inside a pump instead is usually air. Once the excess air pressure of the spring occurs, the compressed medium is passed through the outlet valve. When the piston is pulled back, it closes the inlet valve and closes the exit valve thus using suction to attract additional means of compression.

- Axial piston pump contains a number of pistons attached to a cylindrical block moving in the same direction as the center line of the block. The majority of flow and pressure control circuits can be included internally allowing for reliable operation and simple design of the hydraulic system involved.

This type of pump has a piston placed parallel to the pump shaft and is transmitted by a joint or inclined disc. The piston is always close to the surface of the inclined disc, so it participates in the reciprocal movement of the piston and participates in the rotation of the rotor.

- Advantages of axial piston:

+ Smaller size than radial piston under the same conditions.

+ It is possible to make the size of the push chamber and suction chamber larger without increasing the overall size of the pump.

+ The volume is smaller than the radial piston of the same capacity.

+ High efficiency, regardless of load and number of revolutions.
