The YB1 Series Vane Pump is a widely used hydraulic component, valued for its smooth operation, consistent flow, and adaptability in various hydraulic systems. Its working mechanism combines precise engineering and internal components that work together to move hydraulic fluid efficiently. Understanding this mechanism highlights how the pump provides reliable performance in industrial and mobile applications.

1. Pump Structure and Components

The YB1 Series Vane Pump consists of a rotor, vanes, a cam ring, and an inlet and outlet port. The rotor is positioned eccentrically inside the cam ring, and the vanes are mounted on the rotor with the ability to slide in and out. This structure allows the vanes to maintain contact with the cam ring as the rotor rotates, creating chambers of variable volume to transport hydraulic fluid.

2. Fluid Suction and Transportation

As the rotor turns, the volume of the chamber on the suction side increases, causing hydraulic fluid to be drawn into the pump from the inlet port. The vanes extend outward due to centrifugal force and the cam ring’s shape, forming a tight seal that prevents backflow. The fluid is then trapped between the vanes and carried around the rotor to the discharge side of the pump.

3. Fluid Discharge

On the discharge side, the volume of the chambers decreases as the rotor continues to rotate. This reduction in volume pushes the hydraulic fluid out of the pump and into the hydraulic system. The continuous rotation of the rotor ensures a steady and consistent flow, while the vanes maintain smooth operation and efficiency.

YB2-21 double pump is specially designed for medium and low-pressure hydraulic systems, and its performance is in this range, which makes it suitable for various industrial applications.
YB2-21 adopts a duplex design, combining the output of two pumps to provide greater flow. This means that it can be used in scenarios that require more hydraulic output, such as hydraulic clamps, lifting platforms, and other industrial equipment.
