Briefly describe the main difference between the double-acting vane pump and the vane motor
The vane pump is also a positive displacement pump. It uses the rotation of the rotor and the expansion and contraction of the blades in the rotor chute to complete its closed volume change. Figure 3-6 shows the working principle of a single-acting vane pump. It is mainly composed of parts such as drive shaft
What are the characteristics of the Fujitsu vane pump used in agricultural machinery?
The Fujitsu vane pump is widely used in hydraulic transmissions compared to mechanical transmissions and is a new technology. Since Pascal proposed the static pressure principle in the seventeenth century, hydraulic transmission has been three hundred years old. However, the promotion
What if the vane pump flow is insufficient and the oil cannot be sucked? Reasons and solutions for collection alternate!

What are the classifications of industrial pumps?
Vane pump: The vane pump is the kinetic energy and pressure energy that converts the mechanical energy of the impeller in the pump at high speed into liquid. Because of the curved and twisted blades in the impeller
