Description

Replaceable multistage axial flow pump supporting structure Technical Field The utility model relates to the technical field of multistage axial flow pumps, in particular to a replaceable multistage axial flow pump supporting structure. Background The multistage axial flow pump is a fluid machine which is used for carrying out gradual pressurization on liquid by coaxially and serially connecting a plurality of impellers (usually 2-4), so that high-lift and high-flow liquid delivery is realized. However, the prior art has the following problems: the existing multistage axial flow pump supporting structure is integrally or simply connected through bolts, a transverse constraint mechanism is lacked, the connecting end is easily deviated due to vibration during operation, the coaxiality of a shaft system is difficult to ensure, the pump body is easily worn after long-term use, the efficiency is reduced, and the pump body is required to be integrally detached during maintenance, so that time and labor are consumed. And, traditional bearing structure installs adaptability poor usually, and conventional bearing structure's bottom plate interval is fixed, can't adapt to different specification pump body installation requirements, if need the adjustment then need redesign base or measuring the location many times, and not only installation effectiveness is low, still easily leads to the pump body operation unstable because of the error, is difficult to satisfy various chemical industry demands. In view of the above, the inventors propose a replaceable multistage axial flow pump support structure for solving the above problems. Disclosure of utility model The utility model aims to solve the problems of insufficient stability and durability and poor mounting adaptability of the traditional support structure, and provides a replaceable multistage axial flow pump support structure.
