Abstract
The utility model discloses a horizontal type single-stage centrifugal pump. The horizontal type single-stage centrifugal pump comprises a pump body (11). The horizontal type single-stage centrifugal pump is characterized in that the pump body is provided with a medium flow channel which is defined by a shell, a pump cover (9), an impeller (12) and a motor (1). The medium flow channel is provided with an inlet end, an outlet end and an impeller installation cavity, wherein the axes of the inlet end and the outlet end are vertical to each other, the pump cover (9) is installed on the shell, and a seal ring (19) is arranged between the pump cover and the shell. The impeller (12) is installed in the impeller installation cavity, the axis of the impeller is coaxial to the axis of the inlet end, and a sealing ring (16) is arranged between the impeller and the left side of the impeller before being installed. The motor (1) is installed on the pump cover, a pump shaft (17) is installed at the power output end of the motor, the pump shaft is fixedly connected with the impeller through an impeller nut (15), and a water blocking ring (8) is installed on the pump shaft. The horizontal type single-stage centrifugal pump is little in occupied space, stable to operate, small in noise, good in sealing, not easy to leak, simple in structure and design, convenient to overhaul, and capable of saving construction cost.
