Liyuan Hydraulic A7VO107/A7VO160 Piston Pumps: Pioneering High-Efficiency and Stable Pressure-Flow Measurement SolutionsIn the intricate ecosystem of industrial hydraulic systems, the accurate measurement of pressure and flow stands as a pivotal factor in ensuring optimal equipment performance, minimizing energy consumption, and safeguarding operational reliability. From the precise movement control of construction machinery to the delicate process regulation in precision manufacturing, every link relies on the stable and controllable output parameters of hydraulic power sources. Leveraging decades of technical expertise in the hydraulic sector, Liyuan Hydraulic has launched the A7VO107 and A7VO160 high-performance hydraulic piston pumps. Endowed with core advantages of "precision flow control, stable pressure resistance, and intelligent adaptability," these two pump models provide high-efficiency and stable pressure-flow measurement solutions for various industries, emerging as the "precision power core" of industrial hydraulic systems. Innovative Technical Architecture: The Cornerstone of Measurement PrecisionThe A7VO107 and A7VO160 piston pumps from Liyuan Hydraulic adopt an advanced swashplate variable displacement design, laying a solid foundation for precise pressure and flow measurement from the source. With displacements of 107mL/r and 160mL/r respectively, both pumps boast a rated working pressure of 35MPa and a peak pressure of up to 40MPa, catering to medium and high flow demand scenarios. Their core innovation lies in the integration of a "dual-feedback variable control module." Through real-time data interaction between pressure sensors and flow metering units, closed-loop regulation of output parameters is achieved. The flow control accuracy reaches ±1.5%, and the pressure fluctuation range is controlled within ±0.2MPa, far exceeding the industry average standards of ±3% and ±0.5MPa. In terms of flow measurement optimization, both pumps feature a spiral groove valve plate design, which reduces the impact and leakage of hydraulic oil during distribution, increasing volumetric efficiency to over 96%. A new energy battery manufacturer applied the A7VO160 in its hydraulic forming equipment. By utilizing the pump-integrated flow metering unit to real-time monitor oil delivery volume, the pressure supply deviation of the forming mold was reduced from the original 5% to 1.2%, and the qualification rate of battery pole pieces increased by 8%. Meanwhile, the A7VO107 excels in small-scale precision hydraulic systems due to its compact structure. A machine tool manufacturer integrated it into the hydraulic transmission system of CNC lathes. Through precise pressure regulation, the stability of the tool feed rate was improved by 20%, and the machining accuracy error was reduced to within 0.005mm. Multi-Dimensional Stability Assurance: Adapting to Complex Operating ConditionsHarsh industrial site conditions such as high temperature, vibration, and contamination often lead to deviations or even failures in hydraulic pump parameter measurement. Liyuan Hydraulic's A7VO107 and A7VO160 have established a comprehensive stability assurance system from three aspects: materials, structure, and protection, ensuring the continuous reliability of pressure and flow measurement. In material selection, the pump body is made of high-strength ductile iron QT600-3, with a tensile strength of 600MPa and vibration resistance 30% higher than ordinary cast iron. The piston surface is coated with a plasma-sprayed ceramic layer, achieving a hardness of HV1200, which significantly enhances wear resistance and corrosion resistance. In a mining excavation equipment application in northern China, the A7VO160 piston pump operated intensively for 18 hours per day. Despite the dual challenges of dust and vibration, it maintained measurement accuracy for six consecutive months, reducing equipment failure rates by 50% compared to traditional oil pumps. In terms of structural protection, both pumps are equipped with IP65-rated protective enclosures, effectively blocking dust and water mist intrusion. Additionally, they integrate an intelligent temperature control system that automatically activates cooling devices when the oil temperature exceeds 70℃, ensuring stable operation within an ambient temperature range of -25℃ to 85℃. A metallurgical enterprise used the A7VO107 in the hydraulic control system of a continuous casting machine. In the high-temperature workshop environment, the stability of the pump's pressure measurement remained above 98%, avoiding production interruptions caused by parameter fluctuations. Full-Scenario Adaptability: Covering Diverse Industrial NeedsWith flexible parameter configuration and compatible design, the A7VO107 and A7VO160 can adapt to pressure-flow measurement requirements across different industries, from heavy machinery to precision manufacturing, energy extraction to municipal engineering, forming a comprehensive solution coverage. In the construction machinery sector, the A7VO160 provides power for the boom and bucket hydraulic systems of 20-ton excavators. Through precise flow regulation, it enables smooth switching of movements and reduces fuel consumption by 10%. The A7VO107, on the other hand, is suitable for small loaders. Its lightweight design and efficient pressure feedback mechanism increase equipment response speed by 15%. In the energy industry, a wind farm adopted the A7VO160 to power the wind turbine yaw hydraulic system. Stable pressure control ensured wind alignment accuracy, increasing annual power generation by 3%. To meet the high demands of precision manufacturing, the A7VO107 and A7VO160 can connect to industrial Internet of Things (IIoT) systems, uploading real-time pressure and flow data to the central control platform for remote monitoring and intelligent regulation. An auto parts enterprise integrated the A7VO107 into stamping equipment. By optimizing flow supply through cloud data analysis, the equipment uptime rate increased from 85% to 92%, significantly improving production efficiency. Furthermore, both pumps support customized modifications, allowing the addition of pressure compensating valves, flow control valves, and other accessories according to customer needs, further expanding their application boundaries. Full-Lifecycle Service Support: Enhancing Solution IntegrityLiyuan Hydraulic has built a "pre-sales, in-sales, after-sales" full-lifecycle service system around the A7VO107 and A7VO160 to ensure the effective implementation of measurement solutions. During the pre-sales phase, the technical team provides customized pump selection and system integration solutions based on customers' operating parameters and measurement requirements. In the in-sales phase, professional engineers are dispatched to guide on-site installation and commissioning, ensuring accurate docking of the pressure-flow measurement system. In after-sales service, Liyuan Hydraulic has established 32 service stations nationwide, stocked with sufficient spare parts. It commits to responding to fault reports within 2 hours and providing on-site maintenance within 12 hours for areas within 400 kilometers. When a construction group encountered a sudden pump failure while using the A7VO160 in an overseas project, Liyuan Hydraulic completed spare part deployment and on-site maintenance within 72 hours through cross-border service channels, minimizing project losses. In addition, the company regularly conducts customer training covering equipment maintenance, parameter calibration, and other content to help customers improve the management capabilities of their measurement systems. As core equipment for hydraulic pressure-flow measurement, Liyuan Hydraulic's A7VO107 and A7VO160 piston pumps drive precise measurement through technological innovation, adapt to complex working conditions with stable performance, and empower industrial upgrading with full-scenario services. In the future, Liyuan Hydraulic will continue to iterate hydraulic transmission technology, promote the intelligent and green development of these two pump models, and provide more reliable hydraulic power measurement solutions for high-quality industrial development. |
