Description

Parameter Description of YUKEN Piston Pump A37-F-R-01-C-K-32

1. Model Code Explanation

The model code of YUKEN piston pump A37-F-R-01-C-K-32 has clear implications, which helps to understand the product configuration intuitively:
  • A37: Series identifier, representing the A-series variable displacement piston pump with a basic displacement specification of 36.9 cm³/rev.
  • F: Mounting type, indicating flange mounting.
  • R: Rotation direction, meaning clockwise rotation when viewed from the shaft end (standard rotation direction).
  • 01: Control type, referring to pressure compensator control mode.
  • C: Pressure grade, indicating the adjustable pressure range of 1.2-16 MPa (the maximum intermittent working pressure can reach 21 MPa).
  • K: Shaft extension type, representing a keyed shaft design.
  • 32: Standard design number, corresponding to the standard configuration of the pump.

3. Control and Adjustment Parameters

  • Control Mode: Pressure compensator control (Model 01), which can automatically adjust the displacement according to the system pressure to maintain stable working pressure.
  • Pressure Adjustment: Turning the pressure adjustment screw clockwise increases the pressure; the adjustable pressure range is 1.2-16 MPa, and the pressure adjustment volume per full turn of the screw is 6.5 MPa.
  • Flow Adjustment: Turning the flow adjustment screw clockwise decreases the flow; the minimum adjustable flow is 2.9 cm³/rev, and the flow adjustment volume per full turn of the screw is 3 cm³/rev.

4. Installation and Piping Requirements

  • Mounting Type: Flange mounting (Model F), ensuring stable installation and reducing vibration during operation.
  • Shaft Alignment: It is recommended to use a flexible coupling to avoid bending or thrust stress on the shaft; the maximum permissible misalignment is less than 0.1 mm TIR, and the maximum permissible misangular is less than 0.2°.
  • Piping Specifications: The inner diameter of the suction port pipe should be not less than 16 mm (3/4 inch); the length of the drain pipe should be less than 1 m, and the pipe end should be submerged in oil; the pressure in the pump housing should be maintained at a normal pressure of less than 0.1 MPa and a surge pressure of less than 0.5 MPa.

5. Application Notes

1. The pump is preset to maximum delivery and minimum discharge pressure at the time of shipment; adjust the preset parameters according to the actual system requirements before use.
2. When using steel pipes for suction or discharge ports, avoid excessive load from the piping on the pump to prevent excessive noise.
3. The pump is suitable for various hydraulic oils; when using special fluids (such as water-glycols, phosphate esters), refer to the relevant specifications for parameter adjustment.
4. It is widely used in precision machinery, plastic machinery, die-casting machinery, and other equipment due to its high efficiency, stability, and low noise characteristics.
