Highland Rotary Tillage Machinery Hydrostatic Transmission Higher Reliability

HPV Series Closed Axial Piston Pumps

Variable Displacement Hydraulic Pumps for Closed-Circuit Systems

The Highland HPV Series offers a range of variable displacement axial piston pumps for closed-circuit hydraulic transmission systems.

Across the range, rated displacements run from 30 to 130 mL/rev, and offers multiple control modes, rotation directions, input shaft configurations and auxiliary mounting flange options.

At series level, the technical data covers rated speed 2500 r/min, minimum continuous operating speed 500 r/min, rated working pressure 35 MPa, continuous working pressure 30 MPa, and maximum instantaneous working pressure 42 MPa.

The HPV Series can be tailored by displacement, control mode, rotation direction, shaft interface as well as mounting requirements. Final configuration should be verified against the application hydraulic circuit and installation dimensions.

HPV Series Technical Overview

The supplied technical drawing additionally contains a configuration-level technical requirement showing 30 MPa rated working pressure. The applicable pressure rating should therefore be confirmed against the final pump configuration and engineering documentation prior to integration.

HPV Series Displacement and Performance Range

The HPV Series is supplied in six rated displacement classes.

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

Control and Configuration Options

The HPV Series is based on a model-selection structure covering displacement, control mode, rotation direction, input shaft and auxiliary mounting flange.

Control Modes

• MA — Manual Servo Control
• EP — Electric Proportional Servo Control
• HS — Hydraulic Servo Control

Rotation Direction

• R — Clockwise
• L — Counterclockwise

Input Shaft Options

Depending on displacement and configuration, the series documentation lists:

• 21-tooth shaft, 16/32 pitch
• 23-tooth shaft, 16/32 pitch
• 14-tooth shaft, 12/24 pitch

Auxiliary Mounting Flange

Available configurations include:

• SAE A
• SAE B with 13-tooth spline sleeve
• SAE B with 15-tooth spline sleeve

Highland Rotary tillage machinery hydrostatic transmission basic information:

Highland Rotary tillage machinery hydrostatic transmission 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. Rotary tillage machinery hydrostatic transmission 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.

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

Application Scope

For the HPV130-MA-R-23 configuration, the supplied project documentation provides an agricultural machinery reference, specifically a potato harvester in Kyrgyzstan.

Rather than relying on application category alone, potential application suitability should be determined from the actual hydraulic system requirements. Important selection factors include displacement, pressure, speed, control mode, rotation, shaft interface and mounting configuration.

HPV Series Model Selection

The HPV model structure is defined as:

HPV + Displacement + Control Mode + Rotation Direction + Shaft Configuration + Auxiliary Mounting Configuration
