A10VSO pump

The A10VSO pump is a medium-duty swash plate variable pump manufactured by Bosch Rexroth AG. Here's a closer look at the A10VSO pump:

 First, structural features

 1. Swash plate design: A10VSO pump adopts swash plate design, which makes the plunger cylinder inclined at a certain angle relative to the transmission shaft, so that the plunger can reciprocate. This design makes the pump have the advantages of compact structure, small size and light weight.

 2. Variable adjustment: By changing the angle of the swash plate, the displacement of the pump can be adjusted steplessly, so as to meet different working needs. This variable adjustment allows the A10VSO pump to be used in a wide range of applications.

 3. Reciprocating motion: The plunger is driven by the eccentric rotation of the pump shaft to drive the reciprocating motion, and the suction and discharge valves are one-way valves. This reciprocating motion makes the pump have a high pressure discharge capacity and is suitable for high-power hydraulic transmission.

 Second, performance parameters

 1. Flow range: The flow range of A10VSO pump is usually between 1.8~25.2m³/h, and the specific flow rate depends on the specifications and displacement settings of the pump.

 2. Pressure range: the nominal pressure is 28MPa, and the maximum pressure can reach 35MPa. This allows the A10VSO pump to withstand high operating pressures and meet the needs of a wide range of heavy-duty applications.

 3. Speed range: The speed is usually between 1800~3000r/min, and the specific speed depends on the specifications of the drive motor and the design requirements of the pump.

 4. Plunger diameter and quantity: The plunger diameter is usually between 9mm~15mm, and the number of plungers is generally 9. This design allows the pump to have a high displacement and pressure output capacity.

 Third, the way of control

 The A10VSO pump has a variety of control methods, including pressure control, flow control, power control and electronic control. These controls can be used individually or combined to meet different job needs.

1.Pressure control: By adjusting the pressure setting value of the control valve, the pressure of the hydraulic system can be kept constant. When the system pressure exceeds the set value, the pump will automatically reduce the displacement to reduce the system pressure.

 2. Flow control: The output flow of the pump can be controlled by adjusting the flow setting value of the control valve. When the flow demand of the system changes, the pump can automatically adjust the displacement to meet the demand.
 

3. Power control: By monitoring the pressure and flow of the system, the pump can automatically adjust the displacement to keep the power of the system constant. This helps to avoid system overload and wasted energy.
 

4. Electronic control: through electronic controllers and sensors, accurate control and monitoring of the pump can be realized. The electronic control mode has the advantages of fast response speed and high control accuracy.

 Fourth, Applications

 Due to its excellent performance and wide range of applications, the A10VSO pump is widely used in various industrial fields, such as metallurgy, machine tools, chemical industry, engineering, etc. In these areas, the A10VSO pump is often used as the main power source of the hydraulic system, providing stable and reliable hydraulic power for various actuators.

 Fifth, Maintenance & Maintenance

 In order to ensure the proper operation and longevity of the A10VSO pump, regular maintenance and servicing are required. This includes checking the pump for wear, replacing wear parts, cleaning the tank and filter, checking the tightness of the seals, etc. At the same time, it is also necessary to pay attention to keeping the hydraulic system clean and dry to prevent contamination and leakage of hydraulic oil.
