Single-stage double-suction centrifugal pump

The single-stage double-suction centrifugal pump relates to the technical field of fluid mechanical equipment and comprises a base, a motor, an impeller and a pump body, the pump body comprises a water inlet pipe and a water outlet pipe, water suction chambers are arranged in the pump body and located on the two sides of the impeller, the water inlet pipe communicates with the water suction chambers, guide plates are fixedly arranged in the water suction chambers, and the guide plates are arranged in the axial direction of the water inlet pipe; one end of the flow guide plate is fixedly connected with the shaft sleeve, the other end of the flow guide plate extends into the water inlet pipe, and the distance from the end, away from the center of the pump body, of the flow guide plate to the end of the water inlet pipe is larger than the distance from the center of the pump body to the end, away from the center of the pump body, of the flow guide plate. One end of the guide plate is connected with the shaft sle
