Centrifugal pump

Abstract

The invention discloses a centrifugal pump, and relates to the technical field of centrifugal pumps. The centrifugal pump comprises a base, a pump body and a driving motor are fixed to the top of the base, a water inlet port is fixed to the front side of the pump body, the interior of the water inlet port is communicated with the interior of the pump body, a water outlet port is fixed to the top of the left side of the pump body, and the interior of the water outlet port is communicated with the interior of the pump body. According to the centrifugal pump provided by the invention, when an impeller and arc-shaped blades drive water in the pump body to rotate, centrifugal force borne by sand and stones in the water can enable the sand and stones to approach the inner wall of the pump body, and the sand and stones in the water can be collected through the water pressure in the pump body in the working process by arranging a collecting guide plate on the left side of a cleaning device, the sand and stones can stay in the collecting device to be stored under the cooperation of a filter plate and an arc-shaped barrier plate, and the pressurizing effect of the centrifugal pump cannot be influenced, so that the sand and stones in the water can be accurately screened, and the sand and stones are prevented from rapidly moving to influence the inner wall of a water conveying pipe.

Description

technical field [0001] The invention relates to the technical field of centrifugal pumps, in particular to a centrifugal pump. Background technique [0002] Centrifugal pumps work by rotating the impeller to cause the water to move centrifugally. Before starting the pump, the pump casing and the suction pipe must be filled with water, and then the motor is started to drive the impeller and the water to rotate at a high speed. The water undergoes centrifugal motion and is thrown to the outer edge of the impeller, and flows through the volute pump casing. The pressure water pipeline flowing into the water pump. [0003] During the process of conveying liquid with existing centrifugal pumps, there may be some sand and stones in the liquid. After being pressurized by the centrifugal pump at high speed, these sands will move quickly inside the water delivery pipe, causing a large number of scratches on the inner wall of the water delivery pipe. , thereby reducing the service li...
