Abstract

The invention relates to the technical field of double suction pumps, and discloses a double suction pump capable of preventing water accumulation in a groove. The double suction pump comprises a pump shell and a motor, an impeller is arranged in the pump body, an output shaft of the motor penetrates through the pump shell and is fixedly connected with the impeller, and a water inlet pipe and a water outlet pipe penetrate through the two sides of the pump shell correspondingly. A water accumulation groove is formed in the bottom side of the inner wall of the pump shell, a partition plate is movably connected into the water accumulation groove, a guide rod is installed at the bottom of the partition plate, the bottom end of the guide rod penetrates through and extends to the outer side of the pump shell, a connecting rod is fixedly installed on the bottom side of the partition plate, and a sealing plug is fixedly connected to the bottom end of the connecting rod. A drainage groove is formed in the bottom of the water accumulation groove, a water outlet groove is formed in the bottom of the drainage groove, the bottom of the water outlet groove penetrates through the pump shell, and the sealing plug is in interference connection with the drainage groove. A damping device is arranged at the bottom of the pump shell and plays a role in damping and energy absorption, and meanwhile accumulated water left in the pump shell can be effectively cleaned out.

Description

Technical field: [0001] The invention relates to the technical field of double-suction pumps, in particular to a double-suction pump for preventing water accumulation in grooves. Background technique: [0002] As an important form of centrifugal pump, double-suction pump is widely used in engineering because of its high lift and large flow. The impeller of this type of pump is actually composed of two back-to-back impellers, and the water flow from the impeller is merged into a volute. The double-suction pump has the following characteristics: it is equivalent to two single-suction impellers of the same diameter working at the same time, and the flow rate can be doubled under the same outer diameter of the impeller; the pump casing is opened horizontally, which is convenient for inspection and maintenance. The inlet and outlet of the suction pump are in the same direction and perpendicular to the pump shaft, which is convenient for the arrangement and installation of the pu...
