Abstract
A sliding-vane pump is primarily used to resolve the technical problem that the current vane-type water pump has a shorter delivery lift and needs a powerful power plant. The key points of the technical scheme are as follows: both sides of the inner cavity of the pump housing communicate with the water inlet and the outlet, with the canister jacketing, and the two ends are open and are bushed in the inner cavity. The axial lead of the cylindrical inner cavity of the canister jacketing does not coincide with the axial lead of the cylindrical outer wall of the canister jacketing. Both ends of the cylindrical jacketing separately cooperate with the inner and the outer baffle covers of the bushed canister jacketing, and at the place where the inside of the inner and the outer baffle cover correspond to the water inlet and the outlet, the curved groove is provided. The rotor axle through hole is arranged in the center of the inner and the outer baffle covers and on a side of the pump housing. The rotor axle, running through the rotor axle through hole of the pump housing and the rotor axle through hole of the inner baffle cover, is fixedly connected in the canister jacketing to the rotor. Longitudinal groove is provided on the rotor, and the bushed blades are provided correspondingly in the groove, and the rotor is tangential with the upper part of the inner cavity of the canister jacketing. The structure of the pump is simple, and the relative volume, pulse, noise and vibration are small. In addition, the delivering lift and efficiency of the sliding-vane pump are high and the compatibility is strong.
