In industrial machinery, the hydraulic system serves as the core power source, and its performance relies heavily on the durability and precision of various hydraulic components. However, prolonged high-load operation or improper maintenance can lead to wear and tear, increased downtime, and higher maintenance costs.

As a professional manufacturer of hydraulic pumps and components, Jiangsu KNL(halies) shares 5 practical tips to help you extend the service life of your hydraulic parts and improve system performance.

✅ Tip 1: Replace Hydraulic Oil Regularly and Keep the System Clean

Hydraulic oil is the "lifeblood" of the system. Over time, oxidation and contamination can reduce lubrication and transmission efficiency.
Recommendation: Replace hydraulic oil every 2000–3000 working hours. Clean the oil tank and filters regularly to prevent solid particles from entering the system.

✅ Tip 2: Use Genuine Factory Parts for Better Compatibility

Non-original parts may be cheaper, but they often lack precision and durability, which can lead to leakage, vibration, or malfunction.
Jiangsu KNL(halies) provides a one-stop solution with factory-standard spare parts—including plungers, valve plates, seals, and pump cartridges—fully compatible with major hydraulic equipment brands.

✅ Tip 3: Control System Pressure and Flow to Avoid Overload

Operating under excessive pressure or flow accelerates component fatigue and shortens equipment life.
Recommendation: Configure system parameters properly, avoid frequent start-stops and sudden load changes to prolong pump and motor lifespan.

✅ Tip 4: Maintain Good Sealing to Prevent Leakage

Although small, sealing elements are critical to the system’s efficiency. Worn or incompatible seals can cause oil leakage and pressure loss.
Solution: Use KNL(halies)’s original seal kits, regularly check seal points, and ensure the system remains tightly sealed.

✅ Tip 5: Schedule Routine Inspections and Preventive Maintenance

Don’t wait for breakdowns to happen. Implement a preventive maintenance plan.
Recommendation: Periodically inspect key components like pumps, motors, and valves. Rely on Jiangsu KNL(halies)’s professional team for technical guidance and troubleshooting.
