Four Different Types Of Hydraulic Pumps

In today’s world, we all are acquainted with hydraulic pumps. It is used in a hydraulic drive system. It can be either hydrostatic or hydrodynamic. The main function of parker hydraulic pumps is to convert mechanical power into hydraulic energy. 

After that, hydraulic pumps convert electrical energy into fluid pressure with the help of an electric motor to drive the pump. There are generally three types of hydraulic applications and those include gear, piston, and vane. 

At the pump inlet, a vacuum is created by mechanical action. Hence, it allows atmospheric pressure to force liquid from the reservoir. That is its main function of it. 

Different Types Of Hydraulic Pumps

There are several types of parker hydraulic pumps. Here we are discussing the following types.

Axial piston pump: 

These pumps are efficient and use axially mounted pistons. It reciprocates with internal cylinders for creating alternating suction and discharge flow. It is mainly designed as a variable rate device and is useful in controlling the speeds of hydraulic motors and cylinders. Furthermore, a swashplate is used to vary the depth of each piston. It extends up the cylinder as it starts to rotate. 

Radial piston pump: 

This particular parker hydraulic pump arranged a series of pistons around the router hub. The router mounts in the pumping house and forces the piston in and out of cylinders as it starts to rotate. This causes the hydraulic fluid to suck into the cavity of the cylinder. After that, it discharges from it. The inlets and outlets from the pump stay in the valve in the central hub. One can purchase radial piston pumps from fixed or variable displacement models. The router in the pump is altered to decrease and increase the stroke of the pistons. 

Rotary vane pumps: 

Rotary vane pumps uses a series of rigid vanes that mount in the eccentric router. It sweeps along with the inside wall of a housing cavity. Other than that, the parker hydraulic pumps create smaller volumes. It forces the fluid out through the discharge port. However, some of the design states that the volume of the fluid leaves the pump. It adjusts with the changing rotational axis concerning the pumping house. 

External gear pumps: 

External gear pumps mainly rely on the counter rotating motion of meshed external spur to impact the motion of the fluid. It is commonly found in close-coupled designs. Here the motor and pump share a common shaft and mounting. There is a presence of a small amount of oil and it gets trapped in between re-meshing gears. These gears are very popular in fixed displacement applications. However, its function of it is similar to that of the other gears. 

To sum up, we want to say that different types of parker hydraulic pumps are available. The function of all these is almost similar. However, depending on the needs you need to choose the pump. The main function of the hydraulic pump is to allow atmospheric pressure to force liquid from the reservoir.
