Description

High-performance blade hydraulic pump
Technical field
The present invention relates to Pump with multiple vane more particularly to a kind of high-performance blade hydraulic pumps.
Background technique
Existing blade pump configuration is that a rotor eccentricity is placed in cylinder body, blade radial or with rotor radius at certain Angle is placed in rotor, and rotor high speed rotation when work, blade is thrown away under the influence of centrifugal force, is formed and is sealed with cylinder body Chamber, volume variation generates pressure when rotation.This form vane pump is due to being close by a contact line between blade and cylinder body Envelope, therefore sealing performance is poor, output pressure is lower, in addition the relative linear velocity of blade and cylinder body is very big when rotation, generates Very big friction, causes vane pump overall wear fast, and the service life is short, low efficiency.In this way, the revolving speed of pump cannot be too high.In addition, when rotation In order to guarantee that blade can pass in and out safely in rotor, rotor must have comparable diameter, and the discharge capacity that is bound in this way is smaller, especially become Amount pump, it is even more so.
Summary of the invention
The object of the present invention is to provide be face sealing, not easy to wear, the opposite line of blade and cylinder body at whole sealings Speed very little can be operated with flank speed, and volume very little, discharge capacity is very big, and a kind of very high high-performance blade of output pressure is hydraulic Pump.
In order to achieve the above object, The technical solution adopted by the invention is as follows: a kind of high-performance blade hydraulic pump, including shell Body, blade, matches oil clot and guide pad at rotor, and rotor is located at center, and case cover at least has three pieces in rotor exterior, shell The shifting block being distributed uniformly and circumferentially constitutes sliding slot between two neighboring shifting block, and the rotor sidewall is provided with an annular groove, annular groove It is inside along the circumferential direction uniformly provided with locating slot identical with shifting block quantity, a blade, blade insertion are installed on each locating slot In sliding slot, makes that there is a shifting block in each cavity, be sealed between shifting block and blade by sealing element, two neighboring leaf Piece, ring groove surface, the shifting block between two neighboring blade and a cavity is formed between inner walls;It is provided with and holds on rotor The identical hydraulic fluid port of chamber quantity, hydraulic fluid port are connected with a corresponding cavity, and one end of rotor is connected with oil clot;The outer wall of shell With a dome ring J1, dome ring J1 is placed in the guide groove of guide pad;The axle center of rotor and the axle center of shell are not overlapped;When When rotor rotates, rotor band movable vane piece is rotated together, and blade pushes shell to rotate around its own axis, during rotation, is dialled Block reciprocatingly slides between two blades, so that the volume generating period of cavity changes, to periodically form high-pressure chamber With low pressure cavity, low pressure cavity is by matching oil clot oil suction, and high-pressure chamber is by matching oil clot oil extraction.
Further, be dolioform billiard table A2 that both ends cut out two spherical crowns in parallel in the rotor, billiard table A2 up to Rare three bar grooves B2, respectively billiard table A2, the width of slot B2 and the thickness of blade are identical, and the both ends of billiard table A2 are conical side surface C2 With conical side surface D2, there is slot E2 identical with slot B2 quantity, slot E2 to divide equally conical side surface C2, conical side surface on conical side surface C2 There is slot F2 identical with slot B2 quantity, respectively conical side surface D2, slot E2, slot B2 and slot F2 are sequentially connected logical, and it is fixed to constitute on D2 Position slot;The width of slot E2 and slot F2 are identical as the thickness of blade, there is a hole K2 on conical side surface C2 between two neighboring slot E2, It is spherical surface G2 with the face being connected conical side surface C2, is the half of spherical surface H2, spherical surface G2 and spherical surface H2 with the face being connected conical side surface D2 Diameter and the centre of sphere are identical as the radius of shell Internal Spherical Surface A1 and the centre of sphere, and the both ends of the surface of rotor are anchor ring I2 and anchor ring J2, circle Hole L2 corresponding with hole K2 is evenly equipped on anchor ring I2, hole L2 is connected with corresponding hole K2, hydraulic fluid port is formed, for oil inlet Or oil extraction is used.
Further, the shell has Internal Spherical Surface A1 and spherical outside surface B1, and Internal Spherical Surface A1 is that both ends are parallel with spherical outside surface B1 It cuts out the dolioform spherical surface of different size of spherical crown, is extended with a circle annulus K1, annulus K1 institute to centre of sphere direction on Internal Spherical Surface A1 Perpendicular in the axle center of plane and shell, the both sides annulus K1 are two parallel circular planes C1 and D1, are among annulus K1 Interior Surface of Sphere E1, diameter is equal with the diameter of billiard table A2, places along Internal Spherical Surface A1 radial direction at least three on annulus K1 Long hole F1, long hole F1 divides equally annulus K1, and long hole F1 is sliding slot, so that annulus K1 is divided into several shifting blocks;Spherical outside surface B1 Middle part outwardly protrude a circle annulus J1.
