Hydraulic vane pump PV2R4-136/153/184/200/237-L-RAA-30
1. Product Overview
PV2R4 series vane hydraulic pump is designed for high pressure and large flow industrial applications. This series of vane hydraulic pump has the characteristics of low noise, high efficiency and long life, and is widely used in injection molding machines, die casting machines, engineering machinery, machine tools and other fields that require stable hydraulic power.
Model analysis (taking PV2R4-136-L-RAA-30 as an example):
PV2R4: Serial number.
136: Nominal displacement cm³/rev.
L: Installation method (L means foot installation).
R: Indicates the direction of rotation (from the shaft end), R is clockwise.
A: Direction of oil discharge port (from the shaft end), A is upward.
A: Direction of oil suction port (from the shaft end), A is upward.
30: Design code.
2. Core parameters and performance characteristics
Displacement range: 136, 153, 184, 200, 237 (unit: cc/rev), corresponding to the displacement of different models.
Applicable scenarios: Select the displacement according to the equipment requirements. Large displacement models (such as 237) are suitable for high pressure and large flow situations.
Maximum working pressure: up to 175 kgf/cm².
Volumetric efficiency: ≥90% (optimized blade and stator curve design to reduce internal leakage).
Mechanical efficiency: ≥92% (low friction bearing and seal design).
Energy-saving advantage: Compared with gear pumps, vane pumps reduce energy consumption by 10%-15% under partial load.
Noise level: ≤68dB (A) (5-10dB better than similar products).
Blade pre-stressing design reduces impact noise.
Optimize pump body stiffness and reduce resonance.
Use low-noise bearings and seals.
3. Model comparison and selection suggestions
PV2R4-136-Small and medium-sized injection molding machines, light machine tools
PV2R4-153-Die casting machines, hydraulic presses
PV2R4-184-Heavy construction machinery, large machine tools
PV2R4-200-High-pressure injection molding machines, special test equipment
PV2R4-237-Extreme high-pressure, high-flow industrial equipment
Key factors for selection:
Load requirements: Select the displacement according to the maximum flow and pressure of the system.
Speed matching: Make sure the pump speed range (usually 600-1800rpm) matches the motor.
Installation space: Flange mounting (L) or foot mounting (F) must be compatible with the equipment.
Interface direction: RAA, LAB and other markings correspond to different oil port positions, which need to be confirmed in conjunction with the hydraulic diagram.
