Basic Information
PVV1-1X/027RA15UMB Hydraulic Vane Pump
• Model: PVV1-1X/027RA15UMB
• Type: Hydraulic Vane Pump
• Brand: Rexroth (Germany)
Technical Features
• Working Principle: This pump operates based on the volumetric changes produced by the reciprocating motion of the plunger within the plunger bore. Due to the high-precision fit between the plunger and the plunger bore, which are both circular components, it boasts high volumetric efficiency, smooth operation, uniform flow rate, low noise, and high working pressure.
• Displacement and Pressure: It has a specific displacement and can withstand high working pressures, with specific values varying depending on product batches and application scenarios.
• Design Characteristics:
• Hydraulic balance design for long bearing life.
• Easily replaceable cartridge assembly simplifies maintenance and service.
• Cartridge assembly is interchangeable with competitive products.
• Easily change displacement by replacing the cartridge assembly.
• Rotational flexibility of port positions optimizes customer interfaces.
Application Scope
The PVV1-1X/027RA15UMB hydraulic vane pump can be used in various applications, including but not limited to:
• Engineering Machinery: Providing stable hydraulic power for various types of engineering machinery.
• Hydraulic Systems: Serving as the core power component of hydraulic systems, providing pressurized oil.
• Textile Mills: Driving and controlling the operation of various textile equipment in textile machinery.
Precautions
• Pump Rotation: Vane pumps have a specified rotation direction and must not be operated in reverse. This is because the rotor vane grooves are inclined, the vanes have chamfers, the bottom of the vanes communicates with the oil discharge chamber, and the throttle grooves and suction and discharge ports on the oil distribution plate are designed for a specific rotation direction.
• Assembly Requirements: The oil distribution plate and stator must be correctly positioned using locating pins. The vanes, rotor, and oil distribution plate must not be installed in reverse. The inner surface of the stator in the suction area is most susceptible to wear. If necessary, it can be flipped for continued use, turning the original suction area into the discharge area.
• Disassembly and Maintenance: During disassembly, ensure that the working surfaces are clean. The oil should be well filtered during operation. Additionally, regularly inspect and maintain the pump components to ensure they are in good working condition.
Supplier Information
This model of hydraulic vane pump is produced by Rexroth (Germany) and can be purchased through its authorized dealers or distributors. Prices and services may vary among different suppliers. When purchasing, please consult and compare with suppliers in detail.
I. Product Structure and Working Principle
1. Core Components
• Including rotor, stator, vanes, oil distribution plate, and end covers. The inner surface of the stator is a cylindrical bore, with an eccentric design between the rotor and stator.
• The vanes slide within the rotor slots and are pressed tightly against the inner surface of the stator by centrifugal force and pressure oil, forming sealed working chambers.
2. Working Principle
• As the rotor rotates, the volume of the working chambers increases from small to large (suction) and then decreases from large to small (discharge), completing a suction and discharge cycle.
• It is a single-acting pump (completing one suction and discharge cycle per revolution), also known as a non-balanced pump due to the radial hydraulic unbalanced force acting on the rotor.
• By adjusting the eccentricity between the stator and rotor, the displacement can be changed, supporting variable control.
In summary, the PVV1-1X/027RA15UMB hydraulic vane pump is a superior and versatile hydraulic power component suitable for various engineering machinery and hydraulic systems. When purchasing and using, please follow the product manual and precautions to ensure its normal operation and extend its service life.
