A vertical suspended semi submersible vertical turbine pump infusion device that can prevent user pipeline damage

A vertical suspended semi submersible vertical turbine pump infusion device that can prevent damage to user pipelines. The pump head is connected to the discharge pipe through a water lifting structure, and the transmission shaft passes through the upward water pipe and cooperates with the inference bearing component set on the discharge pipe. It is connected to the motor through a coupling, and the motor is installed on the motor support set on the discharge pipe; The outlet end of the discharge pipe faces to the right and is connected to the user pipeline through fasteners. The lower part of the discharge pipe is connected to a fixed pump foundation, and the left side is connected to a fixed foundation pier; The lifting structure includes multiple interconnected lifting pipes, and bearing seats are installed inside the lifting pipes through a fixed structure; There are threads on the outer side of the connection between adjacent water lifting pipes, and they are connected through a connecting sleeve; This technical method improves the coaxiality between the lifting pipe and the transmission shaft through a unique lifting structure, ensuring the normal operation of the infusion device. At the same time, it balances the static pressure and dynamic reaction force on the side through the foundation pier and pump foundation, avoiding damage to the user's pipeline.

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.
