Sauer 90R100 Series Hydraulic Piston Pump Overview
The Sauer 90R100 series pump is a hydraulic piston pump designed for high-pressure applications, commonly used in hydraulic systems of excavators.
These pumps are known for their robust construction and efficiency, providing the necessary power to drive the excavator's hydraulic system.
Pump Components and Operation
The hydraulic piston pump operates based on the displacement principle. It consists of several key components, including a cylinder block, pistons, swashplate mechanism, and valve plate. As the pistons reciprocate within the cylinder block, they generate hydraulic pressure, which is then directed to various hydraulic circuits in the excavator.
Repair Kits for Sauer 90R100 Series Pump
Repair kits are essential for the maintenance and longevity of hydraulic piston pumps. These kits typically include replacement parts for components that may experience wear and tear over time. Common items in a repair kit for the Sauer 90R100 series pump include piston shoes, cylinder block, valve plate, and seals.
Piston Shoes: These are critical components that directly engage with the swashplate, converting the linear motion of the pistons into rotary motion.
Cylinder Block: The cylinder block houses the pistons and plays a vital role in the pump's displacement mechanism.
Valve Plate: This component controls the flow of hydraulic fluid, ensuring it is directed appropriately within the pump.
Seals: Seals are essential for preventing hydraulic fluid leakage and maintaining the integrity of the pump's internal components.
Excavator Rotary Group
The rotary group in an excavator hydraulic piston pump refers to the combination of components responsible for converting the linear motion of the pistons into rotary motion to drive the hydraulic system. This group includes the cylinder block, pistons, swashplate, and associated components.
Specifications of Sauer 90R100 Series Pump
Displacement: The displacement of the pump refers to the volume of hydraulic fluid displaced per revolution of the pump. It is a crucial parameter that determines the pump's output.
Pressure Rating: The pump is designed to operate within a specific pressure range. The pressure rating is a critical specification to ensure the pump can handle the demands of the hydraulic system.
Speed Range: The pump's speed range is another important consideration, as it determines the operational efficiency and compatibility with the excavator's requirements.
Materials and Construction: The pump is typically constructed with materials that provide durability and resistance to wear, corrosion, and high-pressure conditions.
