Description

Technical Field

[0001] The utility model belongs to the technical field of vertical pump maintenance turning tooling, in particular to a vertical pump maintenance convenient turning tooling. Background Art

[0002] A water pump is a machine that transports liquids or pressurizes liquids. It is mainly used to transport liquids including water, oil, acid and alkali liquids, and is widely used in industrial and mining enterprises. Water pumps are divided into horizontal pumps and vertical pumps according to the installation form. The vertical pump is more difficult to repair than the horizontal pump. The vertical long-axis pump among the vertical pumps is more difficult to repair because of its complex structure and longer pump body.

[0003] There are obvious pain points in the maintenance process of vertical pumps, as follows:

[0004] Normal vertical pump offline maintenance requires the pump body to be lifted out of the pump pit and laid flat on the ground or on a frame for disassembly and maintenance. Disassembly starts from the upper shaft coupling until the impeller, and the installation sequence is exactly the opposite. Starting from the impeller, the lower shaft, bushing, bearing, protective tube, etc. are gradually installed, and then the middle shaft is installed until the upper shaft coupling. Among them, the "coupling" is the first to be disassembled and the last to be installed. During the maintenance process, the pump needs to be turned continuously to find problems and check the fit. As a result, the maintenance personnel have no grip when turning manually (the coupling is the manual turning point when not under maintenance). Usually, they clamp the shaft (non-matching part) with a pipe clamp and turn it, which is cumbersome and inefficient and will cause damage to the shaft. Utility Model Content
