In the intricate network of modern industrial machinery, hydraulic motors serve as the vital converters that translate hydraulic energy into mechanical power, driving the operations of heavy-duty equipment across diverse sectors. Among these, the A2FM107/61W-VZB171-S hydraulic motor by Liyuan Hydraulics stands out as a paragon of engineering excellence. Combining robust performance, unwavering reliability in harsh conditions, and exceptional energy efficiency, this motor has redefined the standards for hydraulic 传动 systems in construction, mining, metallurgy, and beyond. More than just a mechanical component, it represents a harmonious blend of decades of technical expertise and innovative design, addressing the long-standing challenge of balancing high torque output with efficient operation.

At the core of the A2FM107/61W-VZB171-S's appeal lies its extraordinary power delivery, a result of its meticulously engineered plunger structure and precision hydraulic control technology. The motor employs an angled-axis plunger arrangement, where the precise interaction between plungers and the swash plate enables an efficient displacement of 107ml per revolution. Operating at a rated pressure of 31.5MPa, it delivers a maximum torque of 1800N·m, outperforming comparable gear motors by over 40%. A notable application in a large-scale excavator's slewing mechanism demonstrated the transformative impact of this power: after retrofitting with the A2FM107/61W-VZB171-S, the equipment's slewing start-up time decreased from 2.3 seconds to 1.5 seconds, while maintaining smooth operation even under full load, boosting overall earthmoving efficiency by 25%.

The motor's versatility in speed regulation further enhances its adaptability to varied operational demands. It supports a wide speed range from 50 to 2000r/min, with stepless speed variation achievable through compatible proportional control valves. Even at low speeds (50r/min), it maintains stable torque output, eliminating the "jerky motion" commonly encountered in traditional motors. A case study at a port's bulk cargo handling facility highlighted this advantage: the conveyor system driven by the A2FM107/61W-VZB171-S adjusted its speed in real-time based on cargo flow, reducing energy consumption per unit of cargo by 18% without compromising handling efficiency. Additionally, its rapid forward-reverse switching response time of just 0.4 seconds minimizes process transition delays in metallurgical rolling mill auxiliary equipment, enhancing production line continuity.

Optimized energy conversion efficiency translates directly into tangible cost savings for users. Through enhanced valve plate design and the use of low-friction seals, the motor achieves a volumetric efficiency of 94% and an overall efficiency exceeding 90%, offering 12%-15% energy savings compared to 同类 products. In a quarry's crusher equipment, the adoption of the A2FM107/61W-VZB171-S significantly reduced hydraulic system energy losses, cutting daily diesel consumption per unit from 85 liters to 72 liters – a saving of over 40,000 yuan annually based on 300 working days. Moreover, its efficient energy conversion reduces system heat generation, extending hydraulic oil replacement intervals to 2000 hours and further lowering maintenance costs.

The harsh realities of industrial environments demand exceptional adaptability from hydraulic motors, and the A2FM107/61W-VZB171-S rises to this challenge through comprehensive reinforcement. Its housing, crafted from high-strength gray cast iron (HT300), undergoes aging treatment to achieve a hardness of HB200-240, enabling it to withstand severe vibrations and impact loads while maintaining mechanical stability across a temperature range of -30℃ to +80℃. In an open-pit coal mine in Inner Mongolia, the motor operated continuously for 12 months in an environment with daily temperature fluctuations of 40℃ without failure, doubling the service life of the previously used motor.

Innovations in the sealing system form a critical defense against contaminants. The A2FM107/61W-VZB171-S features a multi-layer composite sealing structure, with primary seals made from high and low-temperature resistant fluororubber that retains elasticity and sealing performance even under high pressure. Auxiliary seals utilize PTFE guide rings to reduce friction coefficients and prevent seal wear. For dusty environments, the output shaft end is equipped with a double-lip skeleton oil seal and dust cover, creating dual protection that reduces contaminant intrusion by over 90%. Application data from a cement plant's ball mill drive system showed that after adopting this motor, 故障停机次数 due to dust ingress dropped from 2 per month to 0.3, raising equipment availability to 95%.

Enhanced contamination resistance significantly extends service life. The motor's critical friction pairs (plunger-cylinder block and slipper-swash plate) utilize high-hardness alloy materials (surface hardness HRC60-62) with a special nitriding process, forming a 50μm hardened layer. This allows reliable operation even when oil cleanliness reaches NAS 9 grade, exceeding the industry standard of NAS 8 grade. Its built-in suction filter, with 20μm precision, effectively traps large particulate matter, protecting internal components from wear. In a sewage treatment plant's sludge dewatering machine, the motor maintained stable operation despite minor oil contamination, extending the first overhaul interval by 1500 hours beyond expectations.

Long-term durability is the cornerstone of the A2FM107/61W-VZB171-S's ability to deliver sustained value, achieved through durability optimization of wear components and a modular design philosophy. Its plungers and cylinder bores undergo precision paired grinding, with clearance controlled between 3-5μm – ensuring both sealing performance and reduced friction losses during relative motion. This extends plunger assembly service life to over 10,000 hours, a 60% improvement over conventional processes. In a waste incineration plant's material pushing mechanism, the motor operated continuously in a corrosive environment, and after 8000 hours of testing, all performance parameters showed less than 5% degradation, well below the industry standard of 10%.

Improved maintainability dramatically reduces downtime costs. The A2FM107/61W-VZB171-S adopts a modular assembly structure, allowing key components (valve plates, plunger sets, bearings, etc.) to be replaced independently without full motor disassembly. This reduces routine maintenance and repair time to one-third that of traditional products. Its housing features 预留状态监测接口 for connection to intelligent diagnostic equipment, enabling real-time monitoring of oil temperature, pressure, vibration, and other parameters to 预警潜在故障. Feedback from a municipal engineering company's tunnel boring machine application showed that maintenance time per scheduled service decreased from 8 hours to 2.5 hours, cutting annual maintenance costs by 55%.

Meticulous design details further enhance reliability. The motor's output shaft bearings are reinforced cylindrical roller types with 30% higher load capacity than standard bearings, capable of withstanding significant radial and axial forces. Large-diameter flange connections at oil inlets reduce pipeline pressure losses, while a built-in pressure balancing device automatically compensates for volume changes due to temperature fluctuations, maintaining stable system pressure. On a pile-driving vessel for a cross-sea bridge project, the A2FM107/61W-VZB171-S operated for 3 years in high humidity and salt spray conditions, with inspections confirming that critical indicators such as bearing clearance and sealing performance remained within factory specifications – a testament to its exceptional durability.

As a flagship product from Liyuan Hydraulics, the A2FM107/61W-VZB171-S hydraulic motor transcends conventional performance boundaries, offering unmatched power to overcome efficiency bottlenecks, superior environmental resilience to conquer challenging conditions, and exceptional durability to extend equipment lifecycle value.
