Product details

A7V-LV Hydraulic Piston Pump

I. Basic Overview

The A7V-LV hydraulic piston pump is a high-performance hydraulic component, specifically a swashplate axial piston pump with constant power variable displacement, widely used in construction machinery and mining machinery. It boasts a compact structure, small size, light weight, high power-to-weight ratio, and high variable sensitivity.

II. Working Principle

The working principle of the A7V-LV pump is based on the kinematics of the swashplate axial piston pump. The spherical hinge on the main shaft disc, together with the connecting rod and plunger, forms a spatial five-bar linkage mechanism. When the main shaft disc rotates, it drives the plunger to reciprocate in the cylinder bore of the cylinder block through the connecting rod, thereby achieving suction and discharge of fluid. The variable displacement mechanism of the pump adjusts the flow rate by altering the swashplate angle and cylinder block tilt angle to adapt to different working pressures and power demands.

III. Main Features

1. High Pressure: The A7V-LV pump has a high rated pressure, capable of meeting the requirements of high-pressure hydraulic systems.

2. Multiple Adjustment Methods: The pump offers various adjustment methods, including manual, hydraulic, constant pressure, constant power, and electronic control, allowing for selection based on actual needs.

3. Sensitive Variable Displacement: Through advanced design of the variable displacement mechanism, the A7V-LV pump achieves rapid and accurate flow rate adjustment.

4. Compact Structure: By eliminating the traditional swing frame variable displacement mechanism, the pump has a more compact structure, with reduced volume and weight.

5. Long Service Life: The use of high-quality materials and advanced manufacturing processes ensures a long service life and high reliability of the pump.

IV. Application Fields

The A7V-LV hydraulic piston pump is widely used in construction machinery, mining machinery, agricultural machinery, and other fields, particularly excelling in hydraulic systems requiring high pressure, large flow rates, and constant power output.

V. Precautions

1. Regular inspections and maintenance should be performed on the A7V-LV hydraulic piston pump to ensure its proper functioning.

2. Avoid overloading to prevent damage to pump components.

3. During use, observe the pump's operating state, and promptly shut down and inspect if abnormal noises or leakage are observed.

In summary, the A7V-LV hydraulic piston pump is a high-performance, high-reliability hydraulic component suitable for various hydraulic systems requiring high pressure, large flow rates, and constant power output.
