Danfoss MPV Series Hydraulic Pump: A High-Efficiency, Energy-Saving, and Reliable Variable Piston Pump Designed for Heavy-Duty Engineering Equipment
I. Technical Characteristics
1. Structure and Design
• The MPV series adopts a swashplate axial variable piston structure, complemented by optimized port plates and low-friction materials, ensuring high efficiency and stable performance.
• Key components (such as the cylinder block, main shaft, and slipper shoes) are crafted from high-strength alloy steel and undergo surface hardening treatments (induction hardening/nitriding). Paired with micron-level precision assembly, this enhances the pump's durability and reliability.
2. Efficiency and Energy Conservation
• The total efficiency exceeds 92%, significantly reducing energy consumption.
• Under partial load conditions, automatic pressure/flow adjustment can save energy by 15% to 30%, lowering fuel or electricity consumption.
3. Control Modes
• Supports multiple control methods, including constant pressure control (PC) and electro-proportional control (EP).
• Constant pressure control maintains system pressure stability, avoiding overflow losses; electro-proportional control is compatible with intelligent electronic control systems, enabling precise flow adjustment.
• Response time is ≤50ms, meeting the demands of high-frequency operations.
4. Noise and Vibration
• Through flow path optimization, a vibration-damping housing structure, and dynamically balanced rotors, operating noise is reduced to as low as 78dB(A), improving the operating environment.
• Complies with urban construction environmental requirements, minimizing impact on the surrounding environment.
II. Application Advantages
1. High Adaptability
• The MPV series hydraulic pumps are specifically tailored for heavy-duty engineering equipment such as excavators, rotary drilling rigs, concrete pump trucks, and mining machinery.
• They can adapt to various harsh operating conditions and environments, ensuring stable equipment operation.
2. Efficient Driving
• In high-pressure, large-flow scenarios, the MPV series hydraulic pumps can stably provide the required pressure and flow, ensuring efficient equipment operation.
• Through intelligent variable control, precise flow adjustment is achieved, enhancing equipment operational efficiency.
3. Reliable and Durable
• High-quality materials and advanced manufacturing processes ensure device reliability and durability.
• The mean time between failures (MTBF) exceeds 8,000 hours, reducing equipment failure rates and maintenance costs.
4. Energy Conservation and Environmental Protection
• The MPV series hydraulic pumps prioritize energy conservation and environmental protection in their design and manufacturing processes, reducing energy consumption and environmental pollution.
• They align with the green development concept of modern industry, supporting enterprises in achieving sustainable development.
III. Typical Application Scenarios
1. Earthmoving Machinery
• As the main pump for excavators, it supports multi-way compound actions of the boom, arm, and swing, improving excavator operational efficiency.
2. Piling Equipment
• Applied to the powerhead and pressurization system of rotary drilling rigs, it can withstand high-impact loads, ensuring stable equipment operation.
3. Concrete Machinery
• As the driving pump for the distribution valve and main oil cylinder of concrete pump trucks, it guarantees continuous high-pressure delivery, enhancing concrete pump truck operational efficiency.
4. Port and Lifting Machinery
• Applied to the traveling and lifting systems of reach stackers and container handlers, it ensures stable equipment operation and efficient operations.
IV. Installation and Maintenance Recommendations
1. Before Initial Startup: Be sure to flush the system piping to ensure cleanliness meets standards, preventing impurities from entering the pump and damaging components.
2. Drain Oil Piping: Must be independently returned to the oil tank and must not be combined with the return oil pipe to prevent excessive backpressure from affecting pump performance.
3. Oil Temperature Management: Normal operating oil temperature should be controlled between 40°C and 65°C. If the temperature exceeds this range, check if the cooling system is functioning properly.
4. Regular Maintenance: Check the filter element pressure differential, oil condition, and abnormal pump noise every 500 hours. Promptly replace worn components and filter elements.
