When a machine starts to lose power, jerk or respond irregularly, it is very likely that there is a problem with its hydraulic system. These types of faults usually appear gradually, but if they are not detected in time, they can lead to serious breakdowns that force production to be halted or much more costly repairs to be carried out.
In many cases, the initial signs are minor: a drop in pressure, less precise movements or strange noises during operation. These symptoms are usually related to faults in hydraulic pumps, valves, cylinders or hoses, which are key components for the proper functioning of any industrial machinery.
Signs indicating a fault in the hydraulic system
Hydraulic systems use oil pressure to transmit force and movement. When something is not working properly, the machinery usually shows clear signs that should not be ignored.
Some of the most common symptoms are:
- Loss of power in the movement of the machinery
- Irregular operation or jerky movements
- Abnormal noises in pumps or valves
- Hydraulic oil leaks
- System overheating
- Pressure drop in the hydraulic circuit
These problems can have multiple causes: component wear, oil contamination, seal failures, or even breaks in hydraulic hoses.
Hydraulic components that commonly cause malfunctions
A hydraulic system involves multiple elements that work together. When one of them fails, the entire system can be affected.
Among the components that most frequently cause problems are:
Hydraulic pumps
Pumps are the heart of the hydraulic system. If they lose efficiency or suffer internal wear, the pressure in the circuit decreases and the machinery loses power or precision.
Hydraulic valves
Valves regulate oil flow and pressure. A failure in these components can cause sudden movements, loss of control or irregular operation.
Hydraulic cylinders
Cylinders transform oil pressure into movement. If they leak or their seals wear out, the performance of the machinery is considerably reduced.
Hydraulic hoses
Hoses transport hydraulic oil between the different components of the system. With constant use and pressure, they can deteriorate, leak or even break.
Importance of preventive maintenance in hydraulic systems
One of the most common mistakes in industrial machinery is waiting for a breakdown to occur before taking action. However, hydraulic systems work best when regular preventive maintenance is carried out.
This maintenance allows for the detection of:
- Premature wear of components
- Pressure losses in the circuit
- Contamination of hydraulic oil
- Leaks in connections or hoses
Performing regular checks helps to prevent serious breakdowns, reduce repair costs and increase the service life of the machinery.
Hydraulic workshop and on-site technical assistance
We know that when a machine stops, every minute counts. That’s why we offer both repairs at our specialised hydraulic workshop and on-site technical assistance through our 24-hour mobile workshops.
Our technicians can travel quickly to diagnose and solve hydraulic problems directly at the customer’s facility, minimising downtime.
Prevent major breakdowns in your hydraulic machinery
A small oil leak, a drop in pressure or a damaged hose may seem like minor problems, but if they are not fixed in time, they can cause serious breakdowns in the hydraulic system.
