The Rexroth A4VSO vane pump is a variable displacement pump that is suitable for many industrial applications. Proper maintenance of the pump requires regular replacement and inspection of some key parts.
Rexroth A4VSO Pump Parts
The main internal parts of the Rexroth A4VSO pump that should be monitored include:
- Vanes: The vanes are the sliding parts inside the rotary cylinder that change the displacement of the pump. The vanes make contact with the cam ring and rotor, so they experience a lot of wear over time. Checking the vanes for wear and replacing them as needed is important for optimal pump performance.
- Cam Ring: The cam ring controls the movements and stroke of the vanes. It rotates with the rotor to change the pump chamber volume. The cam ring wears with use and should be inspected periodically for chips, grooves, or other damage.
- Rotor: The rotor is the rotating cylinder inside the pump that houses the vanes. It rotates on the shaft and around the cam ring. With time, the rotor can become scored or damaged, reducing pump efficiency.
- Seal Rings: Seal rings help create a seal between the rotary cylinder (rotor) and the inner bore, preventing hydraulic fluid loss. Cracked, worn or damaged seal rings can cause leaks.
- O-Rings and Gaskets: Various O-rings and gaskets are used inside the pump to prevent hydraulic leaks between components. These rubber parts wear out over time and should be replaced periodically.
- Lancia: The pump shaft transfers rotary motion from the motor to the rotor. It can become bent, scratched or scored from wear, which affects pump performance. Inspecting the shaft for damage and replacing as needed helps maintain pump efficiency.
Replacing A4vso Pump Parts With Some Ideas
When replacing any of these parts, it’s important to use genuine Rexroth A4VSO Parti della pompa for optimal performance and durability. Aftermarket or generic parts may not meet the same quality standards as OEM components.
Ideally, the pump parts should be replaced during scheduled maintenance every 500 A 1000 hours of operation, depending on factors like running conditions and fluid cleanliness. Tuttavia, more frequent inspections are recommended to monitor part wear and catch potential issues early.
Some signs that it’s time to replace parts include excess noise or vibration from the pump, loss of pressure or flow, reduced efficiency and hydraulic leaks. Catching wear issues early can prevent downtime, expensive repairs and damage to other components.
