Many times hydraulic problems can be traced to the specific filtering system being used.


Gear, vane or piston pumps can all provide adequate service; however each type can be prone to different problems.


There are two major areas of cylinder problems; erratic or slow cylinder operation and failure to move the required load.


There are three basic types of accumulators; piston, bladder and diaphragm. Accumulators are commonly used in hydraulic systems as shock suppressors and as a supplement energy source.


By controlling the rate of flow in a hydraulic circuit, it is possible to control the speed of hydraulic cylinders or motors.


A hydraulic power unit has many different components working together, relying on one another for proper and accurate operation. One component failure can have catastrophic consequences.


The control of hydraulic fluid can be disrupted by a burnt out coil, contamination or damaged internal components.



Excessive noise or chatter, along with system overheating can often be traced back to a faulty or incorrect pressure control valve.



Proper oil maintenance is critical in prolonging the life of any hydraulic system.



Correctly sized hydraulic lines are critical for any system.



Some tips on properly installing hydraulic hoses.




When a closed hydraulic system is acting erratically, air is often trapped in the system and cannot escape.
