A7vo107 Hydraulic Pump Repair Parts

Product Description
Hydraulic pump parts A7vo28,107,160,250 rexorth for industrial and machinery
The A7VO series Rexroth,  it adopts a slanted disc structure and is also known for its high performance and reliability. It is widely used in industrial, mobile machinery, and energy fields.
---
A7VO Series Variable Piston Pump parts
1, Product Overview
The A7VO Rexroth is a variable displacement axial piston pump model, designed for open circuits. It complements the inclined axis A7V pump and occupies an important position in many fields with its compact structure, excellent control response, and diverse variable forms. Providing high-quality A7VO replacement parts is crucial for maintaining the performance and lifespan of this top-level pump.

Model Analysis (Example): A7VO 80 LRDU2/63L-NZB01
·A7VO: Series code, inclined disc variable displacement piston pump.
·80: Specification code, representing displacement (approximately 80 cm ³/rev).
·LRDU2: Variable control mode code (in this example, load sensitive control with power limitation).
·63L: Installation flange and shaft extension form code.
·NZB01: Design series and special option codes.

2, Core parts product introduction
The accessories of A7VO pump can be divided into two parts: pump body accessories and regulator (variable control system) accessories.
A. Core parts of pump body:
1. Valve Plate/Port Plate
·Function: The most critical friction pair, fixed to the rear cover, enables switching between oil suction and pressure windows.
·Features: High performance copper alloy or steel back sintered material is used, and the working surface often has wear-resistant coating (such as silver). Its flatness and surface quality directly determine the efficiency and lifespan of the pump.
2. Cylinder Block/Barrel
·Function: It accommodates the plunger and rotates with the spindle, and the plunger performs reciprocating motion in its hole.
·Characteristics: It is usually made of high-strength copper alloy and has extremely high precision in plug holes. The contact between the bottom and the distribution plate is one of the main wear surfaces.
3. Piston and Slipper Assembly
·Function: The plunger completes the suction and pressure oil work; The sliding shoe comes into contact with the inclined plate, converting rotational motion into reciprocating motion.
·Features: The plunger is made of precision ground quenched steel. Sliding boots are usually made of copper alloy or steel back sintered material, forming a lubricating friction pair with the inclined plate. This is the most essential component for motion and force.
4. Swashplate
·Function: Its tilt angle determines the displacement of the pump. The variable mechanism drives it to swing around the axis.
·Features: The surface has undergone ultra-high frequency quenching or nitriding treatment, with extremely high hardness and wear resistance, and works in conjunction with sliding shoes.
5. Retainer Plate
·Function: Under the action of spring force, press a set of sliding shoes tightly onto the surface of the inclined plate to ensure that the pump can also absorb oil normally during start-up and low pressure.
·Features: High flatness, made of high-strength steel.
6. Shaft Seal
·Function: To prevent hydraulic oil from leaking from the spindle extension.
·Characteristic: Usually Tecathane ®) Double lip rotary oil seals from other brands are the most common vulnerable parts.
7. Bearings
·Function: Support the pump spindle and withstand radial and axial forces.
·Characteristics: High precision angular contact ball bearings are usually used.
8. Seal Kit
·Function: Includes all static sealing O-rings, retaining rings, etc.
B. The core accessory of the regulator: The variable control function of A7VO is implemented by its complex regulator, and the structure of regulators with different control methods varies greatly.
1. Pilot Spool and Sleeve
·Function: Sensing system pressure, load pressure, or external control signals, and performing precise displacement to control the oil circuit of variable pistons.
·Characteristics: High precision components with extremely strict clearance requirements, which can cause variable instability after wear and usually require replacement in pairs.
2. Variable piston (Control Piston)
·Function: Respond to the command of the pilot valve and push the inclined plate to change angle.
·Features: Requires good sealing and flexible mobility with the housing holes.
3. Control Spring
·Function: Provide reference force values for pressure control, power control, etc. The characteristics of the spring determine the shape of the control curve.
·Characteristic: Long term use may cause fatigue and lead to set pressure drift.
4. Internal sealing components of the regulator: a large number of small O-rings and gaskets, failure of which can cause internal leakage and malfunction of the regulator.
3, Product features and advantages
·Precision manufacturing: Strictly follow the original factory standards and tolerances of Lishile to ensure perfect compatibility with A7VO pump body.
·Excellent Material: The friction pair components are made of high wear-resistant materials of the same level as the original factory (such as special copper alloy, silver plating, nitride steel), ensuring service life and reliability.
·Comprehensive recovery performance: Using high-quality accessories for repairs can effectively solve:
·Insufficient output pressure and decreased flow rate
·Slow and unstable response of variables
·Severe system heating (low volumetric efficiency)
·External leakage
·Abnormal noise and vibration
·Flexible supply: Different options can be provided from individual key components to complete repair packages.

4, Application scenarios
A7VO pump accessories are used for pump maintenance of the following equipment:
·Industrial equipment: large injection molding machines, die-casting machines, hydraulic presses, machine tool pressure systems.
·Construction machinery: truck cranes, concrete pump trucks, pavers, rollers.
·Mining machinery: rock drilling equipment, underground equipment.
·Energy equipment: wind power variable pitch system, generator control system.
Used for A7VO pump:
·Preventive maintenance
·Repair after malfunction
·Equipment overhaul
