(2) in traditional construction process, the installation quality of guide arm supporting shoe can direct influence the installation quality of guide arm and stealthily dirty pump, traditional guide arm supporting shoe mounting means is through expansion bolts snap-on the lateral wall, the unstable condition appears easily during the installation, can direct influence the straightness that hangs down of guide arm installation and stealthily dirty pump transfer the tightness of coupling terminal surface when installing, and traditional guide arm supporting shoe fixed mode is not fit for being used in the installation and shakes more violent fixed, take place not hard up the back, need fix again, so need change the guide arm supporting shoe again, increase later stage cost of maintenance.
To sum up, for a large submersible sewage pump, the conventional construction technology can destroy the conventional equipment foundation when the large submersible sewage pump continuously vibrates, so that the problems of leakage, waste of a large amount of energy, increase of maintenance cost and the like occur during the operation of the submersible sewage pump.
