Description

High-performance multiple-blade pump

Technical field

The present invention relates to Pump with multiple vane more particularly to a kind of high-performance multiple-blade to pump.

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.
