What is a pressure compensated hydraulic pump?

A pressure compensated pump is a pump that can reduce its output displacement (flow) when the system pressure rises to a specified pressure setting. Variable Displacement, Pressure Compensated.

How does a hydraulic pressure compensator work?

The pressure compensator automatically adjusts the size of the orifice between the inlet flow and compensator spool, modulating the flow of fluid that enters the valve to maintain a constant pressure drop across the variable orifice, providing a constant flow rate through the valve.

What are the advantages of using pressure compensated pumps?

The benefit of a pressure compensated pump is that it will destroke once the pressure builds to the compensator setting, therefore cutting off the pump flow but still maintaining the desired pressure.

How does a pressure compensated piston pump work?

How Does it Work? When the pressure at the outlet port reaches the compensator setting then the compensator spool moves over against the spring force. This allows the pump outlet pressure to have a path to the internal servo piston.

How does axial piston pump work?

In an axial-piston pump, the pistons and cylinder rotate around the center, longitudinal axis. The pistons and shoes move in and out of the cylinder because they are sliding upon a stationary, variable angle, swashblock. As the pistons rotate, they alternate between being connected to an inlet port and an outlet port.

What is meant by pressure compensated?

Pressure compensation is the control of flow by compensating for the changes in load pressure. Most hydraulic systems today use pre-compensation as a means of maintaining consistent flow from an orifice or spool.

How does a axial piston pump work?

What does pressure compensated mean?

What is the difference between axial piston pump and radial piston pump?

A radial piston pump is a type of hydraulic piston pump. The working pistons extend in a radial direction symmetrically around the shaft, marking the main difference beween them and another piston pump, the axial piston pump, which has axially rotating pistons.

What does CF mean in hydraulics?

Critical Flow Factor, often referred to as “Cf” is a coefficient that defines how pressure will recover after it drops to its lowest point inside the control valve. This lowest point is also referred to as the vena contracta*.

What is the purpose of a pressure compensated flow control valve?

What is a Pressure Compensated Flow Control Valve? A pressure-compensated flow control valve has a fixed throttling flow at all pressures. The two-way pressure-compensated flow control valve is also called a series valve. The pressure reducing valve and the smothering of this valve are placed in series with each other.
