Technical Introduction

The vertical suspended semi submersible vertical turbine pump generates static pressure and dynamic reaction force on the discharge side at the discharge pipe mouth. These forces are traditionally borne by the pump outlet pipeline. When these forces are large, it brings difficulties to the design of the pump outlet pipeline. And some users' pipelines have already been designed. If the pipelines are designed according to the pump requirements, they need to be redesigned and rearranged, which brings inconvenience to users and greatly increases the time and manpower costs. Installing a water pump in a pipeline that is not designed according to the requirements of the water pump has a significant impact on the performance and service life of the water pump. The water pump vibrates greatly and the foundation is prone to loosening; It will cause permanent damage to the pipeline. Most suspended semi submersible vertical turbine pumps use lifting structures, which are mostly connected by multiple lifting pipes. Bearing seats are usually installed in the lifting pipes, which are fixed in the lifting pipes through fixing devices. The lifting pipes are mostly matched with flanges set at their connection points and fixed by locking bolts and nuts. Using this method for fixed connection will increase the error as the number of lifting pipes increases, which will affect the coaxiality of the lifting pipes and shafts, affect the normal operation of the pump, and also generate greater lateral static pressure and dynamic reaction force at the connection end with the user pipeline.
