How to diagnose the operation of the hydraulic system?

In our article you will learn how to determine the operation of the hydraulic system. A good diagnosis of the probable cause of its failure greatly reduces the time and cost of repair.

Vigilance above all

Today, construction machinery is so robust that sudden breakdowns are rare. If any part of the hydraulic system is not working as it should, it usually gives some signals sooner. Therefore, the operator should be alert and respond to any suspicious symptoms.
The most common symptoms of a hydraulic system failure include: lack of engine power, or noise in the pump. You can find more symptoms of failure related to the machine’s hydraulics here.
Correctly diagnosing the problem is extremely important because if such symptoms are ignored, it can result in a serious failure. However, diagnosing the operation of the hydraulic system, despite clear symptoms, is not easy.

Something serious or a minor defect?

Malfunction of the hydraulic system raises suspicions that one of the system components has been damaged. However, this does not have to be true. It happens that, the lack of rotation in an excavator is caused by a minor defect, such as a disconnected plug in the coil or a damaged coil. Sometimes it also happens that a seemingly trivial fault may be a consequence of a more serious failure. Therefore, before you decide that the pump is suitable for replacement, consult the service that diagnoses the operation of hydraulic systems.

It doesn’t pay to act blindly

A person with no knowledge of the hydraulic structure and experience in diagnosing such failures may have a big problem with diagnosing the cause of a failure. Very often, a diagram and a detailed specification of a given construction machine are also needed. What’s more, you should know what the pressure should be in the system and where the measuring points are located. Guessing and feeling in the dark can unnecessarily expose the machine owner to high costs.

If the operation of the hydraulic system seems suspicious to you, it is best to contact a professional service immediately. It is worth remembering that a properly made diagnosis guarantees quick failure removal, without generating unnecessary costs.
