Both the 90L100 and 90R100 feature a bent-axis design, a common characteristic in axial piston pumps.
This design allows for efficient fluid displacement and high power density. The bent-axis configuration enables the pump to handle high-pressure conditions with precision and reliability.
Axial Piston Mechanism:
The axial piston mechanism is a fundamental element in these pumps. It consists of pistons arranged in a circular pattern within the pump housing. As the pistons reciprocate, they generate fluid flow by displacing hydraulic fluid in a controlled manner. This design contributes to the pumps' ability to handle high-pressure applications.
Swashplate:
A swashplate is a key component that translates the rotary motion of the drive shaft into the reciprocating motion of the pistons. The angle of the swashplate determines the displacement volume and, consequently, the flow rate of the hydraulic pump.
Port Plate:
The port plate directs the flow of hydraulic fluid to and from the pump. It contains various ports, including inlet and outlet ports, which facilitate the controlled intake and discharge of fluid. The port plate design is crucial for optimizing pump performance and efficiency.
Cylinder Block:
The cylinder block houses the pistons and is a critical component for the axial piston mechanism. It ensures proper alignment and movement of the pistons, contributing to the overall reliability and longevity of the hydraulic pump.
Bearings and Seals:
High-quality bearings and seals are incorporated into the design to minimize friction, reduce wear and tear, and prevent fluid leakage.
These components enhance the efficiency and durability of the pump, particularly in demanding operating conditions.
Specifications:
Displacement:
The displacement of a hydraulic pump refers to the volume of fluid it can deliver per revolution. The 90L100 and 90R100 pumps typically have displacement values specified in cubic centimeters (cc) or liters per revolution.
Pressure Rating:
These pumps are designed to operate under high-pressure conditions. Pressure ratings are usually expressed in bars or pounds per square inch (psi). The precise pressure capabilities depend on the specific model and application requirements.
Speed Range:
The speed range indicates the rotational speed at which the pump is designed to operate effectively. It is typically given in revolutions per minute (RPM). The speed range is an essential consideration for matching the pump to the requirements of the driven machinery.
Efficiency:
Hydraulic pump efficiency is a measure of how well it converts mechanical power into hydraulic power. Sauer 90L100 and 90R100 pumps are designed with a focus on efficiency, minimizing energy losses and heat generation.
Fluid Compatibility:
These pumps are engineered to work with various hydraulic fluids, ensuring compatibility with different industrial applications. The specifications provide guidelines on the type of fluids that can be used for optimal performance.
