Problems solved by technology

This kind of vane hydraulic pump is sealed by a contact line between the vane and the cylinder body, so the sealing performance is poor, the output pressure is low, and there is a lot of friction between the vane, the rotor and the cylinder body during rotation, resulting in compressor failure. The overall wear is fast, the life is short, and the efficiency is low

Embodiment Construction

[0027] figure 1 a and figure 1 b shows the shape of the blade 3 and the sealing strip 4 of the present invention. The blade 3 is approximately semi-circular and has two pieces of the same. A1 and B1 are parallel planes, and the width of the blade 3 is the same as Figure 4 b. The hollow ring of shell 1 has the same width, C1 is a cylinder with the center O1 and the same radius as the cylinder E4 of shell 1, D1 is a sphere with the center of O1 and the same radius as the radius of the rotor 2 ball table C2, E1 is a cylinder The surface, the E1 cylinder is centered on the axis of symmetry passing through the center of the sphere O1, and the radius is O1K1.

[0028] There are four sealing strips 4 in total, one of which is a cylindrical surface with the same radius as the cylinder surface E1 of the blade 3 on the upper side, and a plane on the lower side. The vertical distance between the center of the sphere O1 and the plane is half the thickness of the plate of the rotor 2, G1 I...

Abstract

The invention discloses a spherical hydraulic pump, which comprises a casing, a rotor, two blades, four sealing strips, two oil distribution cones and two cushion blocks. all the sealing places of the pump are surface sealing, and the pump has the advantages of large displacement, high pressure and efficiency, large specific power, compact structure, easy machining, lower cost and long service life.

Description

Technical field [0001] The invention relates to a hydraulic pump, in particular to a new high-performance vane-type hydraulic pump. Background technique [0002] The existing vane-type hydraulic pump structure is that a rotor is eccentrically placed in the cylinder body, and the blades are placed in the rotor at a certain angle to the radius of the rotor. The rotor rotates at a high speed during operation, and the blades are thrown out under the action of centrifugal force to interact with the cylinder body. A sealed cavity is formed, and the volume changes during rotation to generate pressure. This kind of vane hydraulic pump is sealed by a contact line between the vane and the cylinder block, so the sealing performance is poor, the output pressure is low, and the vane and the rotor and the cylinder block generate a lot of friction during rotation, resulting in the compressor The overall wear is fast, the life is short, and the efficiency is low. In addition, in order to ensure ...
