Kawasaki KPN Hydraulic Motor M7V212AC48: Core Specifications & Applications

1. Product Positioning & Series Classification

TheM7V212AC48is ahigh-speed axial piston motorfrom Kawasaki Heavy Industries'M7V series, engineered for high-pressure, high-speed applications. It features aswashplate designand is widely used in construction machinery, industrial equipment, and marine systems. The series prioritizeshigh efficiency, durability, and compact structure, supporting multiple control methods (e.g., electro-hydraulic proportional control, pressure-switching control).

2. Key Technical Parameters

【表格】

Parameter Specification

Displacement 212 cm³ (large displacement model in M7V series, suitable for high-torque demands)

Rated Pressure 42 MPa (max. 50 MPa for extreme conditions)

Max. Speed - Rated load (q_max): 2,900 rpm- Low load (q < 0.6×q_max): 4,600 rpm

Control Methods Electro-hydraulic proportional control, pressure-switching control

Mounting Standards ISO/SAE-compliant spline, output shaft, and threads for universal compatibility

3. Core Advantages

1. Long Service Life

• Swashplate design distributes bearing loads evenly, paired with high-load-capacity bearings to reduce wear.

• Optimized cylinder block rotation and clearance minimize internal leakage, enhancing volumetric efficiency.

2. Low Noise Operation

• Kawasaki’s proprietary low-noise technology suppresses pressure pulsation sources, ideal for indoor or noise-sensitive environments.

3. High Reliability

• Anti-contamination valve core design resists jamming from impurities, suitable for systems with moderate hydraulic oil cleanliness.

• Internal pilot control (select models) eliminates external pressure source requirements, simplifying system design.

4. Typical Applications

1. Construction Machinery

• Cranes: Powers boom lifting/slewing mechanisms for precise positioning and rapid movements.

• Excavators: Controls arm/bucket compound actions to improve operational efficiency.

• Aerial Work Platforms: Integrates manual emergency levers for safe operation during power failures.

2. Industrial Automation

• Die-Casting Machines: Manages clamping, injection, and ejection sequences to shorten cycle times.

• Hydraulic Test Benches: Uses proportional solenoid valves (e.g., Kawasaki KDRDE5K series) for closed-loop pressure/flow control in simulated environments.

3. Marine & Offshore Engineering

• Ship Steering Gear: Employs explosion-proof solenoid valves (e.g., DEH22P-30 series) for hydraulic steering under harsh sea conditions.

• Offshore Platforms: Withstands deep-sea high-pressure operations for drilling equipment hydraulic systems.

5. Selection Guidelines

1. Workload Matching

• Forhigh-pressure/large-flowapplications (e.g., excavator main valves), prioritize M7V212AC48 (42 MPa rated pressure, 212 cm³ displacement).

• Formedium-pressure precision control(e.g., hydraulic test benches), consider Kawasaki’s proportional pressure-reducing valves (e.g., KDRDE5K series).

2. System Integration

• Space-constrained equipment (e.g., mobile forklifts) should select compact motors and verify mounting flange compatibility with reducers.

• Explosion-proof environments (e.g., mines, oilfields) require ATEX-certified solenoid valves.

3. Maintenance & Spare Parts

• Regularly monitor hydraulic oil cleanliness to prevent valve core contamination.

• Follow Kawasaki’s official maintenance manual for recommended seal/bearing replacement intervals.
