Highland Working Principles and Components of Hydraulic Systems in Farm Equipment HPV200

HPV Series Closed Axial Piston Pumps

Variable Displacement Axial Piston Pumps for Closed-Circuit Systems

Highland's HPV Series is a series of axial piston variable displacement pumps built for closed-circuit hydraulic transmission systems.

Rated displacement options span from 30 to 130 mL/rev, together with multiple control modes, rotation directions, input shaft configurations and auxiliary mounting flange options.

Series technical data includes a rated speed of 2500 r/min, a minimum continuous operating speed of 500 r/min, a rated working pressure of 35 MPa, a continuous working pressure of 30 MPa, and a maximum instantaneous working pressure of 42 MPa.

Selection of the HPV Series is based on displacement, control mode, rotation direction, shaft interface and mounting needs. The final configuration should be confirmed against the application's hydraulic circuit and installation dimensions.

HPV Series Technical Overview

The supplied technical drawing also carries a configuration-level technical requirement showing 30 MPa rated working pressure. The applicable pressure rating should therefore be checked against the final pump configuration and engineering documentation before integration.

HPV Series Displacement and Performance Range

The HPV Series is provided in six rated displacement classes.

The table above gives the performance range by displacement class. Individual operating limits should be evaluated according to the selected configuration and operating conditions.

Direction of Rotation

• R — Clockwise
• L — Counterclockwise

Input Shaft Configurations

Depending on the displacement and configuration, the documentation lists:

Highland Hydraulic Motor Pump System notices:

Clean Environment: Maintain a clean working environment when servicing or repairing hydraulic systems. Minimize the presence of dirt, dust, and debris to prevent contaminants from entering the system during maintenance procedures.

Proper Fluid Storage: Store hydraulic fluid in clean, sealed containers to avoid contamination. Prevent exposure to moisture, dust, or other foreign substances. Contaminated fluid can introduce harmful particles into the system, leading to component wear and reduced performance.

Filter Selection: Use high-quality filters designed to remove contaminants effectively. Choose filters with appropriate micron ratings to capture particles of the desired size. Regularly inspect and replace filters as recommended by the manufacturer to prevent clogging and ensure optimal filtration.

Flushing and Purging: When replacing hydraulic components or fluid, thoroughly flush the system to remove any contaminants. Purging the system helps eliminate air and particles that may have entered during maintenance procedures. Follow the manufacturer's guidelines for proper flushing and purging techniques.

Contamination Control Measures: Implement contamination control measures, such as breathers, desiccant breathers, and magnetic filters. These devices can help remove moisture and capture particles, preventing their entry into the hydraulic system.

Applications:

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
