EX200-2 EX200-3 PISTON SHOE, Hydraulic Pump Parts | Partsdic®

The piston shoe is a key part of the hydraulic pump in these excavators.

Its primary function is to transfer hydraulic pressure generated by the pump to the rotating components of the hydraulic motor or cylinder, thereby converting hydraulic energy into mechanical power to drive the various excavator functions, such as the digging arm and bucket. Materials and Construction: Piston shoes are typically made of high-quality materials such as forged steel or cast iron. These materials are chosen for their durability and resistance to wear and tear, which is critical given the harsh working conditions these machines often operate in. The piston shoe is precision-engineered to ensure a snug fit within the pump's cylinder block, allowing for efficient fluid displacement and minimizing leakage. Size and Dimensions: The size and dimensions of piston shoes can vary depending on the specific hydraulic pump model and excavator configuration. In the case of the EX200-2 and EX200-3, the piston shoes are designed to match the hydraulic pump's displacement and flow requirements. These dimensions include the diameter of the piston shoe and its thickness, both of which are engineered to precise tolerances to ensure proper functioning. Surface Finish and Coating: The surface finish of piston shoes is critical to their performance. To minimize friction and wear, the piston shoe's contact surfaces are often polished or coated with materials like chromium or tungsten carbide. These coatings reduce friction, improve efficiency, and extend the lifespan of the piston shoe, which is crucial for maximizing the excavator's uptime.

Pressure Rating: Piston shoes are designed to withstand high hydraulic pressures.

The pressure rating of these components is determined by factors such as the material strength, thickness, and the hydraulic system's operational requirements. For EX200-2 and EX200-3 excavators, the piston shoes are designed to handle the specific pressure levels generated by the hydraulic system. Sealing and Leakage Prevention: Efficient sealing is crucial to prevent hydraulic fluid from leaking out of the pump and causing a loss of hydraulic pressure. Piston shoes are often equipped with seals or gaskets that ensure a tight fit within the cylinder block. Proper sealing is essential for maintaining the excavator's hydraulic efficiency and preventing contamination of the hydraulic fluid.
