Pressure Parameters​

The rated operating pressure of this equipment is set at 250 bar, ensuring stable and efficient operation under normal working conditions. This value meets the basic requirements of most industrial application scenarios. When the system faces transient high - pressure demands, the equipment demonstrates excellent pressure - bearing capacity, with a peak pressure reaching up to 315 bar. This provides reliable support for dealing with complex and changeable working environments.​

Displacement and Flow Performance​

Taking the A10VSO10 model as an example, its performance parameters are highly representative. The maximum displacement of this model is 10.5 cm³, which directly reflects its liquid delivery capacity per unit time. In terms of rotational speed, when the equipment runs at a high speed of 3600 revolutions per minute (rpm), it can achieve a maximum volumetric flow rate of 37 liters per minute, making it suitable for scenarios that require rapid transmission of large amounts of liquid. When the rotational speed is adjusted to 1450 rpm, the flow rate becomes 15 liters per minute, meeting the needs of working conditions with lower flow requirements and emphasizing energy - saving and stable operation, thus demonstrating excellent adaptability to different working conditions.​

Shaft End and Mounting Flange Design​

The shaft end design offers diverse options. According to actual application requirements, users can flexibly configure different types such as spline shafts or smooth - key round shafts. Among them, the spline shaft 19 - 4 (compliant with SAE A - B standard, size 3/4") can achieve efficient torque transmission due to its unique tooth - shaped structure, which is suitable for occasions with high requirements for power transmission. The smooth - key round shaft 19 - 1 (also following the SAE A - B standard) ensures connection stability while being convenient for installation and disassembly, thanks to its smooth shaft surface and keyway cooperation. The mounting flange adopts the SAE two - hole design. This standardized structure not only ensures the convenience of the installation process but also effectively guarantees the stability of the equipment after installation, reducing vibration and offset during operation.​

Oil Port Thread Specifications​

The thread design of the pressure oil port and the inlet oil port fully considers the needs of different users and systems, providing two options: UNF threads and metric threads. For example, the A10VSO10 model uses the 9/16 - 18UNF - 2B thread specification for both the pressure oil port and the inlet oil port. This thread specification not only has good sealing performance, effectively preventing liquid leakage but also enables quick and accurate connection with numerous pipe fittings, valves, and other components that meet the corresponding standards in the market, greatly enhancing the equipment's versatility and compatibility.​

Allowable Axial and Radial Forces​

During the operation of the equipment, the forces borne by the drive shaft significantly affect its performance and service life. The maximum allowable axial force on the drive shaft of this equipment is 400 Newtons, and the maximum allowable radial force is 250 Newtons. These parameter limits ensure that the drive shaft maintains good mechanical performance under various working conditions, effectively avoiding problems such as shaft deformation and wear caused by excessive force, thus guaranteeing the long - term stable operation of the equipment.​

 

Product Features​

1. Precise Pressure Control​

The DR control valve, as the core component for pressure control, adopts an advanced pressure sensing and adjustment mechanism. It can monitor the system pressure in real - time and automatically and precisely adjust the pump's output pressure according to the actual needs of the system. Whether facing minor fluctuations or significant changes in system pressure, the DR control valve can respond quickly. By changing the pump's displacement and other means, it stabilizes the pressure within the set range, providing a stable and reliable pressure output for the entire hydraulic system and ensuring that all system components operate at the optimal working pressure.​

2. High - Efficiency and Energy - Saving Advantages​

The A10VSO series pumps equipped with DR control valves perform outstandingly in terms of the power - to - weight ratio, boasting high power density. This means that under the same weight, this series of pumps can output more powerful power. During actual operation, it has intelligent load - sensing capabilities and can automatically adjust the output flow and pressure according to load changes. When the load is small, the pump reduces the output flow and pressure, minimizing unnecessary energy consumption. When the load increases, it can rapidly increase the output to meet the work requirements. This demand - driven energy - supply mode can significantly reduce energy waste compared with traditional pump products, saving a large amount of operating costs for users and also conforming to the development trend of green and energy - saving in modern industry.​

3. Fast Response Performance​

The A10VSO series pumps feature an extremely short control response time, which benefits from their precise internal structure design and the collaborative operation of the DR control valve. In hydraulic systems, load changes are often sudden and rapid. This series of pumps can detect load changes within an extremely short time and quickly adjust their working status. Whether it is a rapid switch of flow or an instant adjustment of pressure, they can be completed efficiently. The DR control valve, with its sensitive control characteristics, can quickly transmit control signals and drive the relevant components of the pump to act accordingly. This ensures that the hydraulic system can quickly adapt to load changes under various complex working conditions, maintain stable operation, and effectively avoid system failures or decreased work efficiency caused by slow response.​

4. Low - Noise Operation​

This product adopts a hydrostatically relieved swash - plate bearing structure, a unique design concept that fundamentally reduces operating noise. In traditional pump products, friction and impact between components are among the main causes of noise. The hydrostatically relieved swash - plate bearing structure uses the pressure of hydraulic oil to form a stable oil film between the swash plate and the bearing, greatly reducing direct contact and friction between components. At the same time, this structure can effectively buffer the impact force during operation, making the equipment run more smoothly. As a result, the noise generated during equipment operation is significantly reduced, effectively minimizing noise pollution to the working environment. This creates a more comfortable working environment for operators and is also suitable for occasions with strict noise requirements, such as hospitals and laboratories.​

5. Excellent Compatibility Design​

The product uses ISO - standard mounting flanges, and the flange connections comply with SAE metric standards. This dual - standard design endows it with excellent compatibility. It can seamlessly interface with hydraulic equipment, pipes, valves, and other components produced both domestically and abroad that meet the corresponding standards. During the equipment installation and replacement process, users do not need to worry about problems caused by interface mismatches and can complete installation and debugging quickly and conveniently. Moreover, this standardized design is also conducive to equipment maintenance and upgrading. When it is necessary to replace or add components, a large number of standard - compliant accessories are available in the market, greatly improving the equipment's versatility and maintainability.​

6. Long Service Life Guarantee​

This product has excellent suction characteristics, ensuring stable and efficient oil suction under various complex working conditions. It avoids problems such as cavitation and wear caused by poor oil suction, effectively protecting the internal components of the pump. Additionally, it has passed high - speed operation certification, enabling it to operate stably at high speeds for a long time without phenomena such as component fatigue and damage. Furthermore, during the design and manufacturing process, high - quality materials and advanced processing techniques are employed, further enhancing its functional reliability. These factors work together to give the product a long service life, reducing the equipment replacement frequency, lowering the overall use cost for users, and providing higher cost - effectiveness and more reliable performance assurance.​
