Hydraulic systems are essential for many industrial operations, but they can encounter several common faults that affect their efficiency and longevity.
4 Key Issues to Watch
1. Oil Quality and Temperature Issues
Hydraulic systems depend on specific types of oils, such as 20# mechanical oil or 32# hydraulic oil.
These oils must be carefully filtered to prevent contamination.
Contaminated oil can cause poor lubrication and increased wear on moving parts.
Hydraulic fluid is sensitive to high temperatures.
The temperature should not exceed 50 degrees Celsius.
Exceeding this temperature can degrade the oil, reducing system performance and potentially causing damage.
2. Mechanical Failures
Mechanical failures in hydraulic systems often result in abnormal noises.
These noises indicate that the system should be stopped immediately for inspection.
Common causes of these noises include trapped dirt in the intake, clogged exhaust filters, or malfunctioning valves.
For example, if the pressure rises too fast when the pump is switched off under vacuum, it could indicate a leak or a malfunctioning anti-suck-back valve.
3. System Leaks
Leaks in the hydraulic system can occur at pipe joints or due to loose fittings.
These leaks lead to oil leakage and contamination.
Leaks can reduce system pressure, affecting the efficiency of hydraulic machinery.
Additionally, back pressure on the pump due to blocked discharge outlets can reduce pump efficiency and cause internal damage.
4. Maintenance and Inspection
Regular maintenance and inspection are crucial to prevent and detect these faults.
This includes checking lubrication, maintaining cleanliness of all parts, and ensuring proper temperature control of components like the hot plate.
Conducting regular inspections can help identify leaks in the system, including in equipment and related accessories such as downstream and upstream piping.
