Troubleshooting Hydraulic Pressure Intensifiers

hydraulic intensifier

The following seven factors are responsible for the majority of Hydraulic Intensifier problems:

  1. Contamination of the Fluid

If the oil is contaminated, particles could become trapped between the seat and the ball check valves. As a result, the intensifier will continue to operate but will be unable to generate pressure.

Furthermore, particles in the oil may be moved along the ground bores 2, destroying the surface and causing internal leakage through the pistons.

To avoid these issues, a 10 pressure filter should be installed prior to the intensifier.

  1. Large volume under pressure

In applications with a large volume of flow under pressure, activating the internal p.o. check valve causes a very high flow rate inside the intensifier in a very short time.

This high flow rate may be many times the maximum allowable flow rate of the intensifier, and because of the compact design of the Hydraulic intensifiers, the flow passes through the internal check valves, which will be damaged by excessive flow.

3: Too high of an inlet flow

If the maximum flow rating is exceeded, the internal check valve springs will be overcompressed, causing the check valve to fail. Furthermore, excess flow causes the piston speed to be too high, which may result in cavitation. To avoid these issues, the T and P inlet flows should be controlled.

4: Too high of an inlet pressure

When the maximum inlet pressure for the Hydraulic  intensifier is exceeded, the screws that hold the body parts together stretch. The static O-rings between the body parts will be pushed out as a result, and the intensifier will leak. Furthermore, if the screws stretch, internal leakage increases, and the intensifier is unable to increase pressure.

  1. Heat

When exposed to excessive heat, the fluid may become thin and lose its lubricity. This will cause the pistons inside to become stuck in the bores, rendering the intensifier inoperable. To avoid this, adequate cooling should be used. When relieving pressure, you should also configure your circuit so that the return oil flows back to the tank.

  1. Return pressure

The Hydraulic  intensifiers increase the pressure difference between the P and T inlet ports. The expected end pressure may not be obtained in applications with high back pressure in the T line. A separate T line for the intensifier should be considered in these cases.

  1. Air in the oil

The presence of air in the oil is undesirable. Internal parts such as valves and pistons will be damaged as a result, and the intensifier’s performance will be unpredictable. To avoid this, the system should be designed so that there are no pockets of trapped air.

Hydraulic is a supplier and manufacturer of pressure intensifiers for a variety of applications such as construction, mechanical, marine, and industrial.
