Vertical suspended semi submersible vertical turbine pump diaphragm coupling

In order to solve the problems of corrosion and poor high temperature resistance of existing vertical suspended semi submersible vertical turbine pump couplings, the vertical suspended semi submersible vertical turbine pump diaphragm coupling includes a first half coupling and a second half coupling; There is an intermediate shaft between the first half coupling and the second half coupling, and membrane components are installed between the intermediate shaft and both the first half coupling and the second half coupling. The intermediate shaft is fixedly connected to the first half coupling and the second half coupling by fasteners. This technical method of diaphragm coupling has small volume, light weight, and good vibration absorption ability, which can compensate for the axial, radial, and angular displacement of the pump group.

Technical requirements: 1. A vertical suspended semi submersible vertical turbine pump diaphragm coupling, comprising a first half coupling (2) and a second half coupling (4); Its characteristics are:; An intermediate shaft (6) is provided between the first half coupling (2) and the second half coupling (4), and a diaphragm component (7) is provided between the intermediate shaft (6) and both the first half coupling (2) and the second half coupling (4). The intermediate shaft (6) is fixedly connected to the first half coupling (2) and the second half coupling (4) by fasteners.
