Description

Technical Field

[0001] This utility model relates to the technical field of horizontal centrifugal pumps, and in particular to a horizontal centrifugal pump alignment device. Background Technology

[0002] Horizontal centrifugal pumps are designed based on the principle of centrifugal force. High-speed rotating impeller blades drive water to rotate, throwing the water out to achieve the purpose of transportation. When installing a horizontal centrifugal pump with a coupling, it needs to be aligned to ensure that the rotation centers of the two shafts connected by the pump and motor coupling are strictly concentric. The existing technology announcement CN219176622U proposes a horizontal centrifugal pump alignment device, which includes a connecting seat, comprising a first connecting member and a second connecting member that can be adjusted and fixed in position along its length. The first connecting member and the second connecting member are detachably fixed to the centrifugal pump's back wheel. However, this device involves many steps, is cumbersome, and wastes time, thus reducing its effectiveness. Furthermore, it cannot be used properly when the distance between the horizontal centrifugal pump and the motor is small, resulting in poor practicality. Utility Model Content
