Highland Hydraulic piston motors Description:

Highland hydraulic piston motor is the power component of the hydraulic system. Its function is to supply the oil with a certain flow and pressure to the system, so it is also the core component of the hydraulic system. Reasonable selection of hydraulic motors is very important for reducing the energy consumption of the hydraulic system, providing system efficiency, reducing noise, improving work performance and ensuring the reliable operation of the system. The principle of selecting a hydraulic motor: the displacement of the hydraulic motor should be determined first according to the working conditions of the main engine, the power size and the performance requirements of the system, and then its specifications and models should be determined according to the pressure and flow required by the system.

Highland HMF Series Hydraulic Motors Technical Specifications:

Highland Hydraulic piston motor is an important device in the hydraulic system. It relies on the reciprocating motion of the plunger in the cylinder body to change the volume of the sealed working chamber to achieve oil absorption and oil pressure. Highland Plunger motors have the advantages of high rated pressure, compact structure, high efficiency and convenient flow adjustment. They are widely used in occasions where high pressure, large flow and flow need to be adjusted.

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
