A11VG50 belongs to the A11VO series variable axial piston pumps. Its accessories have a high degree of professionalism and precision.

A11VG50 Variable Piston Pump parts - Product Introduction

1, Product Overview

A7 is a model in the Rexroth A7v355 series, widely used in open circuit hydraulic systems for mobile machinery and industrial fields such as excavators, cranes, concrete pump trucks, etc. This series of accessories is designed specifically for the maintenance and repair of the A11VG50 pump, with the aim of restoring its performance and reliability.

Model analysis:
·A7V: Series code, inclined disc variable displacement piston pump.
·O: Used for open circuits.
·G: Variable control method (where G may represent a specific control, such as constant power, etc., to be confirmed with the complete model).
·50: Specification code, representing the displacement of the pump (specific displacement needs to be checked in the table, for example, it may be around 50-60 cm ³/rev).

2, Core accessory product introduction

A complete A7v355 repair kit typically includes the following core wear parts and seals:
1. Valve Plate/Port Plate
· Function: Core friction pair, precise control of the connection and disconnection between the plunger chamber and the pump's suction and pressure ports.
· Features: High performance copper alloy or steel backed composite material is used, and the working surface is often coated with silver (Ag) or other wear-resistant layers to ensure excellent wear resistance and anti bite performance. Flatness and parallelism are lifelines.
2. Cylinder Block/Barrel
· Function: It accommodates the plunger and rotates with the spindle, and the plunger performs reciprocating motion in its hole.
· Characteristics: Usually made of high-performance copper alloys such as CuZnAl. The precision of the plunger hole is extremely high, and it fits perfectly with the plunger. The ball socket is matched with the slider ball head, usually equipped with a pressure plate (Cradle).
3. Piston and Slipper Assembly
· Function: The plunger completes oil suction and pressure inside the cylinder body; The sliding shoe comes into contact with the inclined plate, converting rotational motion into reciprocating motion.
· Features: The plunger is usually made of quenched steel and has a precision polished surface. The bottom of the sliding shoe is made of wear-resistant material and forms a lubricating friction pair with the inclined plate. This component is the most critical dynamic sealing and load-bearing component in the pump.
4. Swashplate
· Function: Its tilt angle determines the stroke of the plunger, thereby controlling the displacement of the pump. The execution object of the variable mechanism.
· Characteristics: The inclined plate of a large pump is usually a repairable independent component. The surface has undergone special heat treatment (such as nitriding), resulting in extremely high hardness and wear resistance.
5. Variable control mechanism components (Control Piston, Spring, etc.)
· Function: According to the control type (such as constant power, pressure cutoff, load sensitivity, etc.), push the inclined plate to change angle and achieve variable.
· Features: including variable piston, servo valve core, feedback rod, spring, etc. Their flexibility and accuracy directly determine the accuracy and stability of variable response.
6. Shaft Seal
· Function: To prevent pressure oil from leaking from the spindle extension.
· Characteristic: Usually Tecathane ®) Waiting for the brand's dual lip rotating oil seal, one lip prevents oil leakage and the other lip prevents dust. This is the most vulnerable part that needs to be replaced regularly.
7. Seal Kit
· Function: Includes all static sealing O-rings, backup rings, etc.
· Features: Made of high-quality materials such as nitrile rubber (NBR) and fluororubber (FKM), it is resistant to high pressure, oil, and high temperature.
8. Bearing
· Function: Support the pump spindle.
· Characteristics: It is usually a high-precision, high load bearing angular contact ball bearing that can withstand both radial and axial loads simultaneously.

3, Product features and advantages

· Precision matching: Strictly manufactured according to the original factory drawings and tolerances of Rexroth A11VG50, ensuring perfect compatibility and installation reliability with the pump body.
· Excellent Material: The core friction pair (valve plate, cylinder body, plunger slide shoe) adopts advanced materials and surface treatment processes (such as silver plating) that are the same or equivalent to those of the original factory, ensuring wear resistance and longevity.
· Performance recovery: Using high-quality accessories for maintenance can effectively restore the original working pressure, flow rate, and volumetric efficiency of the pump, solving problems such as pressure fluctuations, increased noise, and abnormal heating.
· Flexible options: Different choices can be provided from a single key component (such as only replacing the distribution plate) to a complete set of maintenance packages, meeting different levels of maintenance budgets and needs.

4, Application scenarios

These accessories are used for the A11VG50 hydraulic pump:
· Preventive maintenance: Regularly replace vulnerable parts (such as spindle oil seals and seals) to avoid unexpected shutdowns.
· Fault repair: When the pump experiences insufficient output pressure, decreased flow rate, external leakage, abnormal noise, or inability to change variables, replace worn parts.
· Equipment overhaul: After a certain period of operation, thoroughly disassemble, clean, inspect, and replace all worn parts of the hydraulic pump to restore its new pump performance.

5, Selection suggestions and important tips

1. Confirm complete model: A11VG50 is only the basic model. Please provide the complete model number on the pump body nameplate (such as A11VG50EP2D/10R-NZD12K01), as accessories with different control modes (EP, LR, DR, etc.) and specifications cannot be interchanged.
2. Original vs compatible parts: The original parts (Rexroth Genuine) have a 100% matching degree, but they are expensive. High quality compatible accessories are a cost-effective choice, but they must come from suppliers with mature technology and good reputation.
3. Professional maintenance: The A11VO series pump has a precise structure, and disassembly requires professional tools, a clean environment, and profound technical knowledge. It is strongly recommended to have experienced hydraulic technicians perform repairs, as incorrect installation can result in instantaneous damage to the pump.
