Abstract

The utility model relates to a spindle. The spindle comprises a rotor matching shaft and a transmission connecting shaft, wherein the rotor matching shaft is provided with a middle partition plate, and the middle partition plate is integrated with the rotor matching shaft. The spindle has the functions of reducing the friction between a rotor and the middle partition plate, the internal leakage of a pump and the like.

Description

A kind of mandrel

Technical field

The utility model relates to liquor pump, especially a kind of mandrel in the liquor pump.

Background technique

This mandrel is mainly used in being arranged on the pump housing behind the fixed rotor, existing this mandrel cooperates behind the rotor because rotor is dynamic, and the intermediate clapboard of pump body be static state, and the friction between rotor and the intermediate clapboard is large, and the sealing between rotor and the intermediate clapboard is little, so that leak serious in the pump.

Summary of the invention

The purpose of this utility model is to overcome the defective of prior art, provides a kind of so that the mandrel little, that reduce leakage in the pump that rubs between rotor and the intermediate clapboard.

For achieving the above object, the utility model adopts a kind of mandrel, and this mandrel comprises rotor fitted shaft and the axle that is in transmission connection, wherein, intermediate clapboard on the described rotor fitted shaft, described intermediate clapboard and rotor fitted shaft are integrated.

Wherein, described rotor fitted shaft is divided into the first fitted shaft and the second fitted shaft by intermediate clapboard, and described the first fitted shaft is different with the central shaft of the second fitted shaft.

The design of mandrel and intermediate clapboard integral type can realize the maximum balance of rotor motion realizing the quantizing process that rotor and intermediate clapboard are friction sealed, greatly reduces and leaks in the pump and friction, raising pump working life.
