Product details

I. Product Positioning and Core Functions

The MVP30 series is avariable-displacement axial piston pumpdesigned by Italian manufacturer Casappa for medium-to-high-pressure open hydraulic systems. In XCMG rotary drilling rigs, this series primarily serves as afan drive pump, providing stable hydraulic power to the cooling system. This ensures continuous high-efficiency operation under high-temperature, high-load conditions.

II. Technical Specifications and Performance Features

1. Displacement and Pressure

• Displacement range: 28.7 cm³/rev (1.75 in³/rev) to 160 cm³/rev (9.76 in³/rev), compatible with various power requirements across XCMG rotary drilling rig models.

• Maximum peak pressure: 350 bar (5,075 psi), suitable for heavy-duty tasks such as drilling and lifting.

• Maximum rotational speed: 3,000 min⁻¹, ensuring stability during high-speed operation.

2. Energy Efficiency

• Variable swashplate design automatically adjusts displacement based on load, reducing energy waste and lowering fuel consumption.

• Low noise operation (<75 dB), improving the working environment for operators.

3. Structural Reliability

• Integrated bearing design withstands axial and radial loads, extending pump life.

• Supports multi-pump combinations to meet complex hydraulic system demands.

• IP65 protection rating, suitable for harsh construction environments (e.g., dust, mud).

4. Control Options

• Available with pressure compensators, flow/pressure compound compensators (load-sensing), torque controllers, and electro-hydraulic servo controls, adapting to XCMG’s automation needs.

III. Specific Applications in XCMG Rotary Drilling Rigs

1. Cooling System Drive

The MVP30 series powers the radiator fan in rotary drilling rigs, regulating flow and pressure to maintain optimal engine and hydraulic system temperatures. This prevents performance degradation or failures caused by overheating.

2. Model Adaptation Examples

• MVPD30.40D-04S5-LME: Used in specific XCMG rotary drilling rig models, featuring an integrated electronic control module (LME) for intelligent linkage between fan speed and system temperature.

• MVPD30.40D-04S5-PME/MB-V-PEC-2-20/175-D-E: Equipped with a pressure compensator (PME) and electro-hydraulic control interface (PEC), enabling remote monitoring and fault diagnosis for improved maintenance efficiency.

3. Performance Advantages

• Efficient Cooling: Precise fan speed control reduces energy consumption while enhancing heat dissipation, extending equipment lifespan.

• High Adaptability: Operates reliably in temperatures ranging from -20°C to 60°C, meeting global construction requirements.

• Modular Design: Facilitates quick replacement and upgrades, minimizing downtime.
