Sany And Zoomlion Concrete Pump Main Oil Pump A11VL0190LRDH2/11R 1010000275

The A11VL0190LRDH2/11R main hydraulic pump in a concrete pump truck serves a critical function in the hydraulic system. Here is a description of its role:

The A11VL0190LRDH2/11R main hydraulic pump is responsible for generating the primary hydraulic pressure required to operate various functions of the concrete pump truck. It is a variable displacement axial piston pump designed specifically for high-pressure applications.

The main functions of the A11VL0190LRDH2/11R main hydraulic pump are as follows:

1. Concrete Pumping: The main hydraulic pump provides the necessary hydraulic pressure to power the concrete pumping system. It drives the pistons or cylinders that push the concrete through the delivery pipes, enabling the efficient and controlled transfer of concrete to the desired location.

2. Boom Operation: The hydraulic pump supplies hydraulic power to operate the articulating boom of the concrete pump truck. It controls the extension, retraction, lifting, and rotation of the boom, allowing precise positioning and maneuvering of the concrete discharge point.

3. Outrigger Control: The main hydraulic pump delivers hydraulic pressure to the outrigger system of the concrete pump truck. It enables the extension and retraction of the outriggers, which provide stability and support to the vehicle during operation. The pump ensures that the outriggers are securely deployed, maintaining the safety and stability of the concrete pump truck.

4. Mixer Drum Rotation: In some concrete pump trucks, the main hydraulic pump is also responsible for powering the rotation of the mixer drum. It provides the necessary hydraulic force to drive the drum, facilitating the mixing and agitation of the concrete mixture.

5. System Efficiency: The A11VL0190LRDH2/11R main hydraulic pump plays a crucial role in the overall efficiency and performance of the concrete pump truck. It ensures a reliable and continuous supply of hydraulic pressure, enabling smooth operation and precise control of various hydraulic functions. The pump's variable displacement feature allows for the adjustment of output flow, matching the hydraulic power requirements of different operations, and optimizing energy consumption.
