Abstract

The invention provides a mute type vertical multi-stage centrifugal pump, and relates to the technical field of centrifugal pumps. The mute type vertical multi-stage centrifugal pump comprises a motor, the motor comprises a noise reduction mechanism, the noise reduction mechanism comprises an outer sleeve arranged on the outer side of the motor, the inner side of the outer sleeve is fixedly connected with an inner cylinder, the inner bottom end of the outer sleeve is slidably connected with an exhaust ring, the bottom end of the outer sleeve is evenly and fixedly connected with telescopic rods, and the inner side of the top end of the inner cylinder is fixedly connected with a connecting ring; the water inlet mechanism comprises a magnetic water pipe arranged below the motor, the right side of the magnetic water pipe is fixedly connected with an elastic rubber plugging plate, and the inner side of the elastic rubber plugging plate on the right side of the magnetic water pipe is fixedly connected with an arc-shaped baffle. The problems that a large amount of noise is generated due to friction between stone particles in water and fan blades in the multi-stage centrifugal pump, the fan blades are damaged, and the use effect of the multi-stage centrifugal pump is affected are solved.

Description

technical field [0001] The invention relates to the technical field of centrifugal pumps, in particular to a silent vertical multistage centrifugal pump. Background technique [0002] A multi-stage centrifugal pump is a combination of two or more centrifugal pumps with the same function. In terms of the fluid channel structure, the medium pressure relief port of the first stage communicates with the inlet of the second stage, and the medium pressure relief port of the second stage communicates with the inlet of the second stage. The mouth communicates with the inlet of the third stage, so the mechanism in series forms a multistage centrifugal pump. [0003] When using multi-stage centrifugal pumps on construction sites, due to the poor water quality at the source of some construction sites, the friction between the stone particles in the water and the fan blades in the multi-stage centrifugal pump after the water flow enters the multi-stage centrifugal pump makes a lot of no...
