How does a hydraulic pump work?

What is a Hydraulic pump?

The hydraulic pump is used in a variety of different areas. For example, it is often seen in hydraulic machinery, which is responsible for supplying water and oil. Excavators, heavy construction equipment, and other industrial equipment are all designed with this in mind.

The pump that is responsible for the braking function may be found in the mechanics of a variety of equipment and machines.

Working principle of Yuken hydraulic pump

It is necessary to use this variety of Yuken pumps in order to transform mechanical into kinetic energy. In the course of its functioning, torque or speed is converted into a rise in supply or pressure.

The displacement of liquid is the primary mechanism by which it operates. The kinetic energy of the moving material generates the needed flow, which is then employed to generate pressure inside a hydraulic device by applying pressure on the moving substance.

Positive displacement Yuken pumps are pumps that operate on the displacement principle. With this type of Yuken pump, you may construct separate chambers in which the material will go from the suction region to where the injection is being performed.

Given that there is no direct connection between such holes, these types of Yuken pumps may be deployed with ease in situations when the system is under increasing pressure (the pressure level corresponds to its load).

It can also be said that the principle of operation of such a pump is based on the mutual work of mechanical forces and the atmospheric pressure created. Due to their interaction, the fluid moves between the different internal parts of the hydraulic pump.

Applications of Yuken Hydraulic pumps

For many decades and centuries, mankind has been striving to facilitate its work by automating it by any available means and, if possible, replacing the working hands with a variety of equipment.

One of the main and indispensable components in many units has become a Yuken hydraulic pump.

In short, a Yuken pump is a device that converts mechanical energy (speed, torque) into hydraulic energy (pressure, volume flow). Any Yuken hydraulic pump has the following main characteristics:

  • Liquid used
  • Pressure range
  • The minimum and maximum value of speed, operating temperatures, viscosity;
  • Type of drive (clutch, etc.)
  • Service life, availability of service

What are the main types of Yuken Hydraulic Pumps?

Yuken hydraulic pumps can be found non-piston or piston. The latter is the most widespread since they can produce pressures up to five thousand MPa.

Types of Yuken hydraulic pumps

Gear pumps with external teeth are different in compactness, reasonable price, reliability, and simplicity of a design. However, they have a high noise level and pressure limitation.

  • Rotary Yuken pump: This type of Yuken hydraulic pump has sufficient strength and a high level of pressure. At the same time, they are quite expensive due to their complex design.
  • Axial piston Yuken pump: These Yuken hydraulic pumps have a high level of efficiency. They have a variable structure. This Yuken hydraulic pump is sold at a fairly high price and is not well resistant to pollution.
  • Radial Piston Yuken pump: The bulky and expensive Yuken hydraulic pump is also known for its reliability, efficiency, high-pressure levels, and noiselessness.
