Rotor and Vanes: At the heart of the pump cartridge, there's a rotor with precision-machined vanes.
The rotor rotates within the cartridge, and the vanes move radially to create chambers of varying sizes. This movement is crucial for the pump's operation as it draws in and expels hydraulic fluid.
Housing: The housing provides a protective casing for the rotor and vanes, ensuring their proper alignment and reducing the risk of damage. The housing is typically made from materials such as aluminum or cast iron, chosen for their strength and resistance to hydraulic fluids.
Inlet and Outlet Ports: These are connections through which hydraulic fluid enters and exits the pump cartridge. The design and size of these ports play a critical role in determining the pump's flow and pressure capabilities.
Bearings and Seals: Bearings and seals are vital for reducing friction, maintaining proper alignment, and preventing hydraulic fluid leaks. High-quality bearings and seals are crucial for the pump's longevity and performance.
The 28VQH Pump Cartridge operates as a vane pump, which is a type of positive displacement pump. Its operation can be summarized as follows:
Fluid Intake: When the pump cartridge is in operation, hydraulic fluid is drawn into the pump through the inlet port.
As the rotor rotates, the vanes slide in and out of slots within the rotor, creating chambers of varying sizes.
Fluid Compression: As the vanes move outward, the chamber volume increases, resulting in a low-pressure area that draws fluid into the chamber. When the vanes move back in, the chamber volume decreases, compressing the fluid and increasing its pressure.
Fluid Discharge: The pressurized hydraulic fluid is then pushed out of the pump cartridge through the outlet port, ready for use in the hydraulic system to perform various tasks, such as actuating hydraulic cylinders or motors.
The "28VQH" in the product name typically denotes specific features and characteristics of this pump cartridge:
Displacement: The "28" indicates the pump's displacement, which refers to the volume of hydraulic fluid it can deliver per revolution. Displacement is typically measured in cubic inches per revolution (in³/rev) or cubic centimeters per revolution (cc/rev). This number helps determine the pump's flow rate and capacity.
Series Designation: The "VQH" suggests that this pump cartridge belongs to a particular series or family of hydraulic components. Different series may offer variations in terms of materials, performance characteristics, or design features.
Applications: The 28VQH Pump Cartridge is commonly employed in hydraulic systems that demand high-pressure and precision. It is often used in industrial machinery, mobile equipment, and other applications where precise control and high-pressure capabilities are required.
Compatibility: These cartridges are typically designed to be compatible with various hydraulic fluids, including oils and other hydraulic fluids used in hydraulic systems.
