Problems solved by technology

This method is not only time-consuming and laborious, but also not conducive to ensuring the installation quality of the impeller.
At the same time, because the impeller needs to pass through the long rotor shaft, general-purpose industrial presses cannot meet this requirement

Embodiment Construction

[0012] An embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0013] The vertical multistage submersible pump impeller assembly press of the present invention is mainly composed of an isosceles triangle base 1, a lifting platform 2, a column 3, a positioning platform 4, a hydraulic cylinder 6 and an impeller fixing seat 7; The base 1 is fixed on the chassis, three uprights 3 are respectively fixed on the three corners of the base 1, and the three uprights 3 are successively set with a lifting platform 2 and a positioning platform 4 with the same structure as the base 1, and the upper parts of the three uprights 3 are arranged at intervals. A plurality of positioning holes, the middle part of the positioning platform 4 has an impeller shaft hole, and the impeller shaft hole on the opposite side of the positioning platform 4 and the lifting platform 2 is provided with an impeller fixing seat 7, and the impeller fixing se...

Abstract

The invention is a press for assembly of a vertical multistage submersible pump impeller. The press comprises a base in an isosceles triangle shape, wherein the base is fixed on a chassis; a hydraulic cylinder is arranged in the middle of the base, three uprights are fixed around the base; the middle parts of the three uprights are sleeved by a lift table which is connected with the hydraulic cylinder; the upper parts of the three uprights are sleeved by a positioning table; an impeller fixing seat is arranged at the bottom of the positioning table; and pin shafts fixed with the uprights are arranged on the positioning table. With the adoption of a lower end driving method, the trouble that a rotor shaft of a multistage submersible pump penetrates through a driving unit is avoided in the upper end driving process; the pin shafts are adopted to adjust the position of the impeller fixing seat and the distance between the lifting table and the impeller fixing seat flexibly, so as to meet the assembly demand of the multistage impeller pump; the pressure applied on the impeller by the impeller fixing seat is uniform and controllable, so as to improve the assembly quality more conveniently; and a pressing head of the impeller fixing seat can be replaced according to the diameter of the rotor shaft, and is applicable for the assembly of pump bodies in different specifications. The press is simple in structure, convenient in use, high in assembly speed and economical and practical.

Description

technical field [0001] The invention relates to a special press machine for assembling the impeller of a vertical multi-stage submersible pump, especially suitable for the installation of impellers, grinding wheels and the like on the rotor shaft of the vertical multi-stage submersible pump. Background technique [0002] The installation of the impeller of the vertical water pump requires an interference fit between the impeller and the rotor shaft, and because the disc body of the impeller is thin, the requirements for dynamic balance are very precise, and the impeller that has passed the dynamic balance test is not allowed to be deformed or bumped. At present, when the impeller is installed in the workshop, experienced workers need to beat the impeller slowly and evenly with a hammer, and complete the installation of the impeller by visual inspection and experience. This method is not only time-consuming and laborious, but also not conducive to ensuring the installation qu...
