Product details

I. Core Spare Parts Composition

1. Pump Body

• Material: High-strength ductile iron or cast steel, with strong impact resistance for high-pressure applications.

• Function: Serves as the main structure of the pump, housing critical components such as pistons and valve plates, and forming hydraulic oil flow channels.

2. Piston

• Material: Precision-machined alloy steel or ceramic-coated for superior wear resistance.

• Function: Achieves suction and discharge of hydraulic oil through reciprocating motion, acting as the core power output component.

3. Valve Plate

• Material: Stainless steel or special alloy, with a highly polished surface.

• Function: Controls the flow direction of hydraulic oil, enabling smooth switching between suction and discharge while minimizing internal leakage.

4. Swashplate

• Function (for variable-displacement pumps): Adjusts the piston stroke by varying its angle, thereby regulating pump displacement (e.g., in V30D series variable pumps).

• Material: High-strength alloy steel with surface hardening for wear resistance.

5. Bearings

• Type: Cylindrical roller bearings or spherical roller bearings.

• Function: Supports rotating components (e.g., drive shafts) to reduce friction and ensure smooth operation.

6. Seals

• Material: Fluororubber (FKM) or polytetrafluoroethylene (PTFE).

• Function: Prevent hydraulic oil leakage and withstand high-temperature, high-pressure environments.

II. Technical Characteristics

1. High-Pressure Performance

• Rated pressure up to 35 MPa, suitable for construction machinery requiring high pressure (e.g., concrete pump trucks, excavators).

2. Variable Displacement Adjustment (Optional)

• Some V30D models support swashplate angle adjustment for stepless displacement variation, meeting load-sensing control demands.

3. Modular Design

• Standardized spare part interfaces enable quick replacement and maintenance, reducing downtime.

4. Corrosion Resistance

• Key components use stainless steel or special coatings to adapt to harsh environments (e.g., marine applications).

------

III. Application Scenarios

1. Construction Machinery

• Hydraulic system main pumps for concrete pump trucks, excavators, and rotary drilling rigs.

2. Industrial Equipment

• High-pressure hydraulic power applications in injection molding machines, die-casting machines, and hydraulic presses.

3. Marine Hydraulics

• Deck machinery and steering gear systems on ships.
