This not only requires additional drilling of holes in the object, but also requires additional tools to install the pump body, which is inconvenient and has a small scope of application. A high-efficiency rotor vane pump is proposed to solve the problem.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0011] In a possible design, the mounting mechanism includes two bidirectional screw rods, four movable grooves and four movable plates. Rectangular grooves are opened on the two connecting plates. The four movable grooves are respectively arranged on the bottom inner walls of the two rectangular grooves. The two ends of the two bidirectional screw rods are rotatably connected to the inner walls on both sides of the two movable holes. The threads of the two bidirectional screw rods are respectively located in the four movable grooves.

[0015] In the present application, when in use, the pump is composed of a rotor, a stator, and blades. The function of the rotor vane pump is mainly to suck the liquid into the pump through the centrifugal force generated by the blades on the rotor during rotation, and then discharge the liquid from the other end of the pump through pressure. When the rotor vane pump starts to rotate, the blades expand outward under the action of centrifugal force, sucking the liquid into the pump, and then under the constraint of the internal groove, the liquid is squeezed and transported, and finally discharged from the outlet of the pump. The pump body has good suction performance, and the liquid can be sucked into the pump due to the centrifugal force generated by the rotor blades during rotation. Especially when conveying liquids with higher viscosity, the suction performance of the rotor vane pump is better, which can realize the vane pump to transport the oil and ensure its high efficiency in transporting the oil. When installing the pump body, turn the rotating handle, and the rotating handle drives the bidirectional screw to rotate, and the bidirectional screw drives the two movable plates to move. The movable plate clamps and fixes the object to be fixed, and fixes the pump body to the object.
