Description:
The hydraulic pump of the underground electric scraper produced by the company is a swash plate displacement pump, which is mainly used in a closed circuit drive system. The direction of the pump output flow changes as the swashplate angle crosses the neutral or zero displacement position;
Scraper hydraulic pump motors are mainly used in closed circuit drive systems. The direction of the pump output flow changes as the swashplate angle crosses the neutral or zero displacement position;
Axial plunger variable, its product is easy to handle.
Tapered roller bearings, the pump can withstand high radial loads
The advantages are simple operation, no terrain restrictions, independent work, fast driving speed and high production efficiency.

Notices:
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.
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
