Agricultural machinery hydraulic motor pump system introduce:

Agricultural machinery hydraulic motor pump system from Highland of China, we can provide agricultural machinery hydraulic motor pump system with high quality, high-performance parameters. Pump is the variable one that is with Charge Pump, and the motor the quantitative, or variable one with valve assembly. The control way of variable displacement pump and motor can be manual or hydraulic operated, and can simply control speed, direction and power of the output shaft of hydraulic motor.

Agricultural machinery hydraulic motor pump system user shall ensure that the hydraulic pump uses the correct formulation of the medium to ensure the cleanliness of the operating medium of the equipment, and shall not contain solid particles.

(Self-cleaning filters are recommended) and use this pump/motor wisely!

Precautions:

Hydraulic oil

The suitable replacement period for hydraulic oil in a sealed tank system is 2000 hours, and more often if the hydraulic oil is contaminated with water or other external materials or subjected to abnormal operating conditions.

As a general recommendation, the 10µ inlet oil filter should be replaced every spring or every 1500 hours (whichever occurs first) on a sealed tank system, or in an open tank system with an air filter fill cap. The oil filter should be replaced every 500 hours.

Heat Exchanger

The heat exchanger core and fins are kept clean at all times for maximum cooling and system efficiency, and the exterior of the heat exchanger is checked daily for blockages and cleaned as needed.

Highland Agricultural machinery hydraulic motor pump system tank:

The tank level and the water present in the oil should be checked daily. If the tank must be filled with oil, filtered hydraulic oil must be used, and all water in the tank must be removed as required.

Use occasions:

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
