The Hydraulic Pump Spring Spacer Plate is a circular flat component used in axial piston hydraulic pumps to correctly position the piston return springs and maintain consistent spring preload. Its main function is to ensure that each piston’s return spring is seated firmly and operates with uniform tension, helping restore the pistons to their starting positions after each stroke. This spacer plate is installed inside the rotating group, situated between the cylinder block and the retainer or valve plate. It provides a stable seat or platform for each spring, aligning them properly with the corresponding pistons. Without this plate, the springs may shift or compress unevenly, leading to unstable piston movement and potential mechanical imbalance.Attributes:• Resists deformation under load.• Supports uniform piston movement.• Helps distribute force evenly across the piston group during operation.Applications: The Hydraulic Pump Spring Spacer Plate is located inside the rotating group of an axial piston hydraulic pump, between the cylinder block and the spring retainer, to maintain proper spacing and alignment for the piston return spring, ensuring stable and consistent piston retraction in hydraulic pump assemblies.
