What signs indicate that the hydraulic cylinder needs maintenance?

The hydraulic system is an indispensable part of all kinds of machinery, and the hydraulic cylinder, as the actuating element in the hydraulic system, its importance is self-evident. The smooth operation of hydraulic cylinders is also very important for improving productivity. Therefore, just like other mechanical components, long-term use will cause wear and tear on the hydraulic cylinder, making it inefficient or even causing mechanical damage. So, are there any corresponding signs before the hydraulic cylinder is damaged? The answer is affirmative. There will be several obvious signs of damage to the hydraulic cylinder. Identifying these warning signals before complete damage can avoid the costs of maintenance, replacement and unexpected downtime.

Warning signals of hydraulic cylinder damage.

1. Liquid leakage

Liquid leakage is a relatively common problem in hydraulic cylinders. It not only affects the function of the equipment but also causes environmental pollution and increases maintenance costs. The aging of seals, improper installation methods, damage to the interior of the cylinder or the piston, etc., may all cause liquid leakage. If liquid leakage occurs, we need to take measures as soon as possible to prevent further leakage and more serious problems.

2.Corrosion.

Depending on the working environment, hydraulic cylinders may suffer from varying degrees of corrosion. Technical issues such as improper surface treatment of the piston rod may lead to corrosion of the base material. Hydraulic oil that has not been replaced for a long time can also cause damage to the interior of the cylinder due to corrosive substances inside the hydraulic oil.

3.Noise.

The normal operation of a hydraulic cylinder will not produce noise. If your hydraulic cylinder makes strange noises during use, it is very likely that there are air bubbles in the hydraulic oil or inside the cylinder, causing a malfunction. If you find that the hydraulic cylinder is making unpleasant noises, then you need to repair it; otherwise, it may start to contaminate the fluid or burn out the seals.

It is very important to know the warning signals of the hydraulic cylinder, which can help you reduce the cost of replacement.
