Embodiment Construction

[0011] see figure 1 , the hub is welded by the hub body 1, the hub cone 2, and the cone support rib 3. The hub body 1 of the impeller is processed into the shape shown in the figure, and the hub cone body 2 is rolled from a steel plate. After being shaped into a specified size, it is welded with the hub body 1 and the cone body support rib 3, and the welded hub is machined to the required size. The blades are stamped out of the steel plate according to the designed shape. according to figure 1 In the indicated position, the processed two hubs are welded with the intermediate partition 4 to ensure that they are on the same axis, and then the blade 5 and the blade rib 6 are welded. The blank of the welded impeller is completed, and after heat treatment, the shape of the impeller is machined to the design size. For finished impeller see figure 2 .

[0012] The inner surface of the hub cone body 2 is welded with a cone body support rib 3, and the cone body support rib 3 supp...

Abstract

A water-ring vacuum pump vane wheel comprises vanes, an intermediate baffle, a wheel hub body and a hub conical surface body. Between two symmetrical wheel hub bodies located on the same axis is set a certain space. The hub conical surface body is welded on the cylindrical side of the wheel hub body. The intermediate baffle is welded between two hub conical surface bodies and the vanes are welded on the wheel hub, hub conical surface body and the intermediate baffle.

Description

[technical field] [0001] The invention relates to the technical field of water ring vacuum pump impellers, in particular to a water ring vacuum pump impeller. [Background technique] [0002] At present, the impellers of existing water ring vacuum pumps all adopt cast impellers or cast hubs, and then weld the blades. Cast impellers or cast hubs have the disadvantages of unstable quality and prone to defects resulting in waste. Moreover, the casting size deviation is large, and the impeller balance is difficult. In addition, the cost of the cast impeller is high, and the production cycle is also long. [Content of the invention] [0003] The object of the present invention is to solve the above-mentioned deficiencies and provide a water ring vacuum pump impeller. [0004] In order to achieve the above object, the present invention proposes a water ring vacuum pump impeller, including blades, intermediate partitions, hub body, hub cone body, characterized in that: between t...
