In the complex system of industrial production, hydraulic pumps serve as the core power source, whose performance directly determines the operational efficiency and production effectiveness of equipment. With decades of technical accumulation and innovative strength in the hydraulic field, Liyuan Hydraulic has launched the A7V117 swashplate axial piston pump. Boasting excellent high-efficiency power output, stable and reliable performance, and wide scenario adaptability, it has become the preferred power choice for numerous industrial equipment, injecting strong kinetic energy into various heavy-duty working conditions and helping enterprises achieve an overall upgrade in production efficiency.

As a leading enterprise in China's hydraulic industry, Liyuan Hydraulic has always taken technological innovation as its core driving force and built a complete industrial chain from R&D and design to production and manufacturing. The company has a national-level technical center and a post-doctoral research workstation, gathering hundreds of hydraulic experts and mechanical engineers to form a professional R&D team. Equipped with internationally advanced 3D modeling software, hydraulic simulation systems, and precision machining equipment, it has achieved precise optimization of technical parameters from the very beginning of product design. A strict quality management system runs through the entire product lifecycle. Raw materials undergo multiple screenings such as spectral analysis and hardness testing. The machining accuracy of core components is controlled at the micrometer level. Finished products must pass dozens of rigorous tests including high and low-temperature tests, pressure impact tests, and durability tests to ensure that each A7V117 piston pump meets international advanced quality standards. It is this technical strength and commitment to quality that have made Liyuan Hydraulic a trusted hydraulic solution provider for many enterprises at home and abroad.

The A7V117 swashplate axial piston pump integrates the dual advantages of efficiency and reliability in its structural design. It adopts an innovative swashplate structure, achieving efficient conversion of hydraulic energy to mechanical energy by optimizing the swashplate angle and piston arrangement. With a rated displacement of 117mL/r, this golden displacement design can not only meet the power needs of medium and large-sized equipment but also realize precise control of energy. The swashplate structure makes the pistons move more smoothly in the cylinder block, reducing the impact of radial force on the pump body and lowering friction loss during operation, laying a solid foundation for efficient power output. Meanwhile, the pump adopts an integrated design concept, organically integrating the pump body, variable mechanism, and control valve group, simplifying the pipeline connection of the hydraulic system, reducing pressure loss, improving the overall efficiency of the system, saving equipment installation space, and facilitating flexible arrangement in various machinery.

Efficient power output is the core competitiveness of the A7V117 piston pump. Its rated working pressure can reach 35MPa, and the maximum pressure can reach 40MPa. At a rated speed of 2500r/min, the output torque is stable and strong, capable of easily driving heavy-duty operations of large construction machinery and mining equipment. The volumetric efficiency is as high as over 95%, and the mechanical efficiency exceeds 90%, which means minimal loss in the energy conversion process, effectively reducing energy consumption. Practical application data shows that compared with similar equipment using traditional hydraulic pumps, equipment equipped with the A7V117 piston pump has improved operating efficiency by 15%-20% and reduced energy consumption by more than 10%, significantly enhancing the production efficiency of enterprises.

In terms of reliability and durability, the A7V117 piston pump also performs excellently. The pump body is made of high-strength alloy forged steel, 经过 multiple heat treatment processes, with a hardness of up to HB300 and a compressive strength of over 650MPa, capable of withstanding long-term high-pressure impact and vibration effects of complex working conditions. Pistons and cylinder blocks are made of high-quality bearing steel, 经过 carburizing and quenching treatment, with a surface hardness of HRC62-65. Combined with high-precision grinding technology, the fit clearance between pistons and cylinder blocks is controlled at 0.003-0.005mm, effectively reducing internal leakage and improving volumetric efficiency. The valve plate adopts advanced Babbitt alloy coating technology, with excellent wear resistance and sealing performance, ensuring smooth flow of hydraulic oil under high pressure and reducing pressure pulsation. Key seals are made of imported fluororubber materials, maintaining good sealing performance in the temperature range of -40℃ to 120℃, effectively preventing hydraulic oil leakage and adapting to harsh working environments with high dust and humidity.

The application scenarios of the A7V117 swashplate axial piston pump are extremely extensive, playing a core power role in multiple industrial fields. In the field of mining machinery, the pump provides strong power for excavators, loaders, crushers and other equipment. When large excavators are engaged in heavy-duty excavation operations, the A7V117 piston pump drives the coordinated action of the boom, arm and bucket, maintaining efficient operation even in the face of hard rock; during the ore crushing process of crushers, the pump outputs stable pressure to drive the crushing hammer to impact at high frequency, ensuring crushing efficiency and quality, and still operating reliably in the dusty underground environment.

In the field of construction machinery, the A7V117 piston pump is widely used in cranes, road rollers, pavers and other equipment. When cranes are lifting heavy components, the pump provides precise power control for the luffing mechanism and hoisting system, ensuring stable lifting and movement of heavy objects; during road construction of road rollers, it drives the rolling wheel to operate continuously through stable pressure output, ensuring the compaction degree of the road surface meets the standard. In the field of metallurgical equipment, the A7V117 piston pump provides power for the hydraulic systems of rolling mills, continuous casting machines and other equipment. In high-temperature and high-dust environments, its reliable performance ensures continuous metallurgical production, meeting the strict requirements for pressure and flow during the rolling process.
