What are the key points in maintaining the hydraulic system of HOWO cement mixer truck?

The hydraulic system is the backbone of a HOWO cement mixer truck, ensuring smooth operation and efficient mixing. Proper maintenance is crucial to prevent breakdowns and extend the equipment’s lifespan. Here are the key points to keep your hydraulic system in top condition:

1. Regular Hydraulic Fluid Checks

Hydraulic oil is vital for lubrication and pressure transmission. Check the oil level frequently and top it up if needed. Contaminated or degraded oil can cause system failure—replace it as per the manufacturer’s recommendations (typically every 1,000–2,000 operating hours).

2. Monitor for Leaks

Hydraulic leaks lead to pressure loss and reduced efficiency. Inspect hoses, seals, and connections regularly. If you notice oil spots or dripping, address the issue immediately to prevent further damage.

3. Cleanliness is Critical

Dirt and debris can clog valves and damage components. Always use clean oil and ensure the hydraulic reservoir cap is sealed tightly. Replace filters periodically to maintain optimal fluid purity.

4. Inspect Hoses and Fittings

High-pressure hoses can wear out over time. Look for cracks, bulges, or abrasions, and replace damaged hoses promptly. Tighten loose fittings to prevent leaks and pressure drops.

5. Maintain Proper System Pressure

Incorrect pressure settings can strain the hydraulic pump and motor. Use a pressure gauge to verify that the system operates within the recommended range (refer to HOWO’s manual).

6. Prevent Overheating

Excessive heat degrades hydraulic oil and damages seals. Ensure the cooling system (if equipped) works efficiently, and avoid overloading the mixer to reduce strain on the hydraulic components.

7. Lubricate Moving Parts

Bearings, cylinders, and other moving parts require proper lubrication. Use the correct grease and follow the maintenance schedule to minimize wear.

8. Professional Servicing

While daily checks are essential, schedule professional inspections annually or after heavy usage. A certified technician can detect hidden issues and perform necessary repairs.

Conclusion

A well-maintained hydraulic system ensures reliable performance and reduces costly downtime. By following these key points, HOWO cement mixer truck owners can maximize efficiency and prolong their equipment’s service life.
