HPV110 Harvesters Agricultural Hydraulic Pumps Piston Structure

Product Description

Highland HPV110 applications of hydraulic pumps in agriculture harvesters
 
Highland Agricultural hydraulic pumps basic introduction: 
 
Highland Agricultural hydraulic pumps are important device in the agricultural harveser hydraulic system. Highland agricultural hydraulic pumps are typical volumetric fluid hydraulic pumps, driven by the prime mover, converting the input mechanical energy into the pressure energy of the liquid, and then inputting it into the system in the form of pressure and flow. It is hydraulic power source of the hydraulic system. Because it can transport liquids under high pressure, it is widely used in in agricultural machinery and daily life.

Highland Hydraulic power units hydraulic pumps main features:
 

• Variable displacement axial piston pumps
• Widely for agricultural machinery
• Connect additional pumps
• Swash plate structure
• Big displacement
• High efficiency
• High pressure
• Simple layout
• More stable

• Highland company has 20 years’ experience in hydraulic industry, could help solve all problems of hydraulic users.

 
Highland HPV110 applications of hydraulic pumps usage: 
 
With the improvement of science and technology, nowadays Highland agricultural hydraulic power units are becoming more and more common, Highland HPV110 hydraulic pumps could make hydraulic farming easy, which are used for kinds of agricultural machinery, such as agricultural harvesters, grass mower, tractors, sprayers, track loaders, forage harvesters etc farming machinery.
 
Hydraulic oil notice of Highland agricultural harvesters hydraulic pumps: 
 

Hydraulic oil: The ability of hydraulic drives to maintain ideal performance and achieve life expectancy depends on the quality of the liquid operating in the unit. Liquid quality can be measured in three common categories: lubrication capacity, impurities, and temperature. Field experience shows that most drives fail due to the damaged surface of liquid quality, mainly solid particles impurities and overheating. Users of hydraulic pumps should choose correct hydraulic oils and maintain promptly.

Factory Performance Testing

Performance verification of the LPV110-MA-R-23 uses a closed-loop hydraulic pump test bench. The test documentation records Component No. 02601310203001, a test on 2025/1/31 at 15:32, a test temperature of 24.3 °C and a power recovery ratio of 50%. Rated displacement is 110 mL/rev and rated pressure is 35 MPa; the test-bench main parameters are a maximum speed of 2900 r/min and a maximum pressure of 42 MPa.

Recorded Test Data

The closed-loop report records speed, pressure, flow, displacement, torque, input power, output power, overall and volumetric efficiency, and charge pressure for the LPV110-MA-R-23. Selected test points are listed for reference.

Charge pressure: 1.7 MPa; charge flow 28.3 L/min. All values are taken directly from the original test record and depend on the test-bench measurement and calculation method.

Engineering Drawing & Dimensions

The supplied LPV110-MA-R/L-23/13/14-NN drawing specifies the mounting flange, output shaft spline, hydraulic ports, control interface and rotation direction of the LPV110-MA-R-23. Key interface information includes:
