The structure diagram of single-suction multi-stage segmented centrifugal pump includes horizontal segmented multi-stage centrifugal pump structure, horizontal self-balancing multi-stage segmented centrifugal pump structure, vertical multi-stage segmented centrifugal pump structure, medium and low pressure boiler Multi-stage segmented centrifugal pump structure, high-pressure multi-stage boiler single-suction segmented structure, etc.
The multi-stage segmented centrifugal pump is a vertically split multi-stage pump. It consists of a front section, a tail section and several middle sections, which are connected as a whole by four long rod bolts. The number of impellers installed on the pump shaft represents the number of stages of the centrifugal pump. Each impeller in the middle section is equipped with a guide wheel. The function of the guide wheel is basically the same as that of the volute, mainly converting kinetic energy into static pressure energy. The impeller is generally single suction, and the suction people all face one direction. In order to balance the axial force, a balance disc is installed behind the end section, and a balance tube is used to communicate with the inlet of the front section. The rotor can move left and right in the axial direction during the working process, and the thrust of the balance disc balances the axial force of the impeller group to maintain the rotor near the equilibrium position. Both ends of the shaft are supported by bearings and placed on a bearing seat, and both ends of the shaft are equipped with shaft sealing devices.
