Notices:

To ensure the optimal performance of hydraulic piston motors, follow these guidelines:

a. Correct Sizing: Choose a motor that matches the specific requirements of your application to avoid overworking the motor or wasting energy.

b. Proper Filtration: Maintain effective filtration systems to keep hydraulic fluid clean, preventing contaminants from damaging the motor.

c. Seal Inspections: Regularly inspect seals and gaskets to identify potential leaks that could compromise both efficiency and safety.

d. Prevent Cavitation: Ensure the hydraulic system is properly designed to prevent cavitation, which can lead to motor damage and decreased performance.

e. Training: Train operators and maintenance staff in the correct usage and maintenance procedures to maximize the motor's lifespan and performance.

Application:

Mixer truck: concrete mixer truck, cement mixer truck;

Coal mining machinery: scraper;

Industry: pharmaceutical machinery;

Transport vehicles: road rollers, concrete pump trucks, stabilized soil mixers
