Highland Beet harvester hydraulic motor pump system describe:

We Highland hydraulic produce LPV110+LMF110 closed loop circuit variable displacement axial piston pump for combine harvester hydraulic system. Our axial piston pumps have high volumetric efficiency, small leakage, high performance and high quality, which can work under high pressure, but their structure is complex and much high request on oil cleanliness.

Highland Beet harvester hydraulic motor pump system standard:

LPV Series Technical parameter

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.

Beet harvester 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.

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

Factory Production & Inspection Evidence
