Product Description

A4VG180EP A4VG40 A4VG50 A4VG140EP4D1 A4VG125 Series A4VG140EP4D1/32R-NAF02F021DP-S Variable Displacement Axial Piston Pump

 

The Rexroth A4VG180 piston pump is an oblique-axis axial piston variable displacement pump for closed circuit hydrostatic transmission. Here are some common features and application scenarios for the A4VG180 plunger pump:

● Features: It has a fixed displacement and is used for hydrostatic transmission in a closed system; the cylinder block and the oil distribution plate adopt spherical oil distribution, which can automatically align during rotation, with small peripheral speed and high efficiency; the drive shaft can withstand Radial load; low noise.

●Application scenarios: Widely used in hydraulic systems in shipbuilding, petrochemical, mining, construction and other industries, such as steering gear hydraulic pumps, etc.

Common faults and troubleshooting methods of Rexroth A4VG180 plunger pump are as follows:

 

1. Excessive working noise: It may be caused by air in the oil pump, low oil level in the oil tank, improper installation of the oil pump and motor, excessive viscosity of the hydraulic oil, etc. It can be solved by opening the oil pump filling port when the pump is running, allowing the air in the pump to be discharged from the filling port, adding enough oil, checking and adjusting the concentricity of the oil pump and motor installation, and selecting hydraulic oil with appropriate viscosity.

 

2. The pointer of the pressure gauge is unstable during operation: serious wear between the oil distribution plate and the cylinder or the plunger and the cylinder, the variable angle of the variable mechanism is too small, the oil inlet pipe is blocked, the oil suction resistance increases, and air leakage is possible. causing this fault. In this regard, you can check and repair the mating surface between the oil distribution plate and the cylinder block, grind and assemble the single cylinder, replace the plunger, tighten the screws at each connection, eliminate leakage, and select hydraulic oil of appropriate viscosity.
