Problems solved by technology

[0002] The centrifugal pumps, mixed-flow pumps, and agitators currently in use are all locked with a single key. When the medium comes into contact with the key, the surface of the key will be corroded, easily damaged by erosion, and the locking is unreliable, resulting in a gap between the impeller seat and the drive shaft. It will cause looseness, which will bring greater economic losses to users.

Embodiment Construction

[0011] All features disclosed in this specification, or steps in all methods or processes disclosed, may be combined in any manner, except for mutually exclusive features and / or steps.

[0012] Any feature disclosed in this specification (including any appended claims, abstract and drawings), unless expressly stated otherwise, may be replaced by alternative features which are equivalent or serve a similar purpose. That is, unless expressly stated otherwise, each feature is one example only of a series of equivalent or similar features.

[0013] Depend on figure 1 The shown impeller seat includes a shaft hole 1 and an impeller bracket 2. The impeller bracket 2 is welded on the shaft hole 1. There is a stabilizing hole 3 on the shaft hole 1. There is a stabilizing bolt 4 on the stabilizing hole 3. On the forward bolt There is a nut 5. In practice, the bolts are tightened first, and then the nuts are tightened in the opposite direction, so that there will be no looseness with t...

Abstract

The invention discloses an impeller base, which comprises a shaft (1) and an impeller support (2), wherein the impeller support (2) is welded on the shaft (1). The impeller base is characterized in that: a stabilizing hole (3) is formed in the shaft (1); and a stabilizing bolt (4) is arranged on the stabilizing hole (3). The impeller base disclosed by the invention cannot be loosened with a transmission shaft, and cannot bring loss to a user.

Description

technical field [0001] The invention relates to the field of impellers, in particular to an impeller seat. Background technique [0002] The centrifugal pumps, mixed-flow pumps, and agitators currently in use are all locked with a single key. When the medium comes into contact with the key, the surface of the key will be corroded, easily damaged by erosion, and the locking is unreliable, resulting in a gap between the impeller seat and the drive shaft. Looseness will occur, which will bring greater economic losses to users. Contents of the invention [0003] In order to overcome the deficiencies of the prior art, the present invention provides an impeller seat, which is reliable in locking, will not loosen with the transmission shaft, and will not cause loss to the user [0004] In order to achieve the above object, the technical solution of the present invention is: an impeller seat, including a shaft and an impeller bracket, the impeller bracket is welded on the shaft h...
