Pricipal working condition:

This system works on a very simple hydraulic cylinder working principle: Force applied at one point is transferred to another through the use of an incompressible fluid. All force generated by the cylinder is provided by the hydraulic fluid (oil or viscous).

Common damage is cylinder scratches, cracks, deformation and warping. There are many causes of cylinder failure but are divided into the following main groups:

• Cylinders are affected by the surrounding environment to warp and warp.
• Hydraulic oil has deposits, dirt and iron particles that reduce oil quality.
• Foreign body or metal debris enters the cylinder.
• Improper installation of the cylinder or during the installation process, there is a strong impact that causes the cylinder to be scratched or scratched.
• The temperature of the cylinder medium is too high, causing the cylinder to deform.
• The cylinder load is too heavy, the high pressure causes the cylinder to deform.
• The environment is too harsh at sea with high concentrations of salt and moisture in the air, causing local or complete corrosion of the working surface of the cylinder rod.

Cylinder not working or when the operation is strange sound or vibrating is one of the problems:

• Cavitation – often happens and leaves serious consequences.
• Using gaskets that are not the right size, too large or too small for requirements.
• Hydraulic oil with gas causes the cylinder to jerk or vibrate when performing forward and backward.
• The pressure supplied to the cylinder is unstable, abnormally increased or decreased, too high or too low compared to the required level.
• Installation mistake: Screws are not tightened, hydraulic valve is not installed correctly, pump is in reverse, pump pipe is installed correctly.
• Due to the mechanical structure.
• The cylinder is deformed due to the pipe being twisted.
• Unstable pump flow can be caused by the pump or the pipeline.
