Radial Piston Motor Failure: What You Need To Know

Radial piston motors are one of the most powerful and strong  , low speed high torque (LSHT) hydraulic motor invention. It does not need a speed reduction device such as a gearbox.

In this setup, radial piston motors are usually structured in a star-shaped pattern and their alignment to the driveshaft is usually perpendicular.

The major components found in a radial piston motor are pistons, cam and piston block.

Although the speed of radial piston motors is relatively low compared to the axial piston motors, however, they develop a high number of revolutions.

This high number of torque explains why radial piston motors are best suited for equipment such as full-size excavator, backhoes, and compact track loaders.

However, whatever your use for radial piston motors may be, sourcing them from a professional manufacturer is the best way to have a great deal on your investment.

Piston Block of Radial Piston Motors

In the radial piston motor, an important and critical part is usually the piston block, which is located centrally in the drive motor.

The drive motor on it part, is known to produce the power needed to trigger the rotation of the output shaft. As the output shaft rotates, this also causes the track or the tire to spin.

In the radial piston motor, this part is so important and special such that if it fails to function, you will surely experience a fault in the working of the radial piston motors.

In most cases, piston block is said to fail because of hydraulic uncleanliness leading to failure in the hydraulic system.

Thus, contamination is the major cause of failure in radial piston motors.

Contamination of Hydraulic

Hydraulic contamination is usually triggered by rust, dust and debris which gain access into the system while carrying out periodic maintenance of the radial piston motors through ruptured seals and split air breather.

At other times, the contaminants are released, such as scrapings and metal flakes.

Generally, contaminants that affect radial piston motors are of two kinds which are abrasive and non-abrasive contaminants.

Some contaminants such as pipe sealant, weld splatter, casting sand can find their way into the system during the process of manufacturing and assembly.

Prevention of Hydraulic Contamination

Hydraulic contamination can be controlled and prevented by applying two easy maintenance procedures:

1. Regular check and replacement of the filter.

2. Proper and routine change of the hydraulic oil.

Doing these will reduce the level of contamination of your radial piston motor to the barest minimum.

There are lots of gains in keeping your motors free from contamination. These are:

1. Longer component life

2. Less component tear and wear

3. Increased efficiency

4. Reduced downtime

5.  More consistent output or performance.

Symptoms of Fault in Radial Piston Motors

It is effortless to detect damages to a radial piston motors by checking out for symptoms such as lunging and power outage originating from one part of the motor tracks.

Any time you are encountering similar symptoms like these, make a quick check on the filters, and the hydraulic fluid before the worst takes place.

In Need Of Some High-Quality Radial Piston Motors?

Yes, following these preventive measures and carefully paying attention to your radial piston motors can avert potential failure of the engine and thus helping you to enjoy its service for an extended period.
