What is pressure reduction?

Pressure plays a vital role in the smooth operation of a hydraulic system. To ensure that the circuit as a whole functions correctly, it is essential to choose the right mechanical components. It is therefore essential to take into account the pressure that will be applied throughout the circuit, as well as the fluid flow rate at the inlet and outlet. Whether the pressure is high or low, it is important to monitor it regularly to ensure the stability of the system. Today we're looking at what pressure reduction is . Let's find out more in this article.

Pressure in a hydraulic circuit

First of all, we need to remember what a hydraulic system is. It is a set of components that use pressurised fluid to perform mechanical work.

Pressurising this fluid, a mineral oil, releases considerable force. The flow is generated by a hydraulic pump, and there is also a protective device responsible for ensuring that the pressure throughout the installation is bearable.

Understanding pressure and flow

Pressure is a physical force that results in an exchange of momentum in a thermodynamic system, particularly within a solid element or a fluid. In the case of hydraulic pressure, we are talking about an external pressure exerted on one part of a confined fluid which is transmitted to all the other parts, without any loss. A constant pressure must be maintained in order for the fluid to continue to circulate

The flow rate of a fluid is the volume of liquid water passing through a cross-section of the flow, per unit of time. In everyday life, this definition can also be applied to the flow rate of water in our pipes, for example. In all cases, the volume of water flowing through a given space is measured.

Pressure reduction

As we have seen, pressure is essential to keep the machine running. It is this pressure that enables the power within the system to be increased or reduced. But today we are particularly interested in pressure reduction. What is it and what does it do? A pressure reducer is a device placed at the end of a circuit. It lets the hydraulic oil through until it reaches the desired pressure. When it does, the pressure reducer closes to maintain the desired pressure at all times. This prevents the pressure from rising further, which could damage the entire circuit. There are two types of pressure reducer. The first is a "two-way" model, and the second is a "three-way" model. It is the three-way type that is most often found in circuits, as it offers a number of advantages. In particular, it allows oil to be drained from the channel into the reservoir.

How do you choose the right pressure regulator? All you need to do is base your choice on the flow rate you want to let through and the pressure values you want to apply within the system, and of course, the maximum pressure of the supply circuit. For the rest, don't hesitate to contact professionals who can take all these factors into account and advise you as best you can.
