A vertical submerged centrifugal pump

Abstract

The invention relates to the technical field of centrifugal pumps, in particular to a vertical submerged centrifugal pump, which includes a centrifugal pump body, a water outlet, an adjustment structure, a water-conducting hose, a connecting flange, a first support rod, a first rotating shaft, a second Two support rods and support structures. The beneficial effects of the present invention are: by installing a water-conducting hose between the connecting flange and the centrifugal pump body, the connecting flange used to connect the drain pipe can be adjusted at any angle. When it is low, the connecting flange can change the angle to reduce the connection height of the drain pipe, which is convenient for the operator to install. At the same time, there are first support rod and second support rod connected by rotation between the connection flange and the centrifugal pump body, which can limit The movement range of the connecting flange ensures that the connecting flange can only rotate on the same plane, which is convenient for adjusting the angle of the connecting flange while reducing the damage to the water-conducting hose caused by rotation and avoiding the bending of the water-conducting hose.

Description

technical field [0001] The invention relates to the technical field of centrifugal pumps, in particular to a vertical submerged centrifugal pump. Background technique [0002] Centrifugal pumps work by rotating the impeller to make the water centrifugally move. Before the pump is started, the pump casing and the suction pipe must be filled with water, and then the motor is started, so that the pump shaft drives the impeller and the water to rotate at a high speed. into the pressurized water line of the pump. Centrifugal pumps can be widely used in electric power, metallurgy, coal, building materials and other industries to transport slurries containing solid particles. Such as hydraulic ash removal in thermal power plants, slurry transportation in metallurgical concentrators, coal slurry and heavy medium transportation in coal washing plants, etc. When the centrifugal pump is working, the pump needs to be placed on land, the suction pipe is placed in the water, and the pu...

AI Technical Summary

Problems solved by technology

The mud pump and the submerged centrifugal pump are limited by the structure, the motor needs to be placed above the water surface during operation, and the pump must be fixed when it is put into the water, otherwise, the motor will be scrapped if it falls into the water

Moreover, since the length of the long axis is generally fixed, the installation and use of the pump are more troublesome, and the application occasions are subject to many restrictions.

[0003] Traditional submerged centrifugal pumps have different specification heights for different liquid surface depths. When the liquid level is shallow, the traditional submerged centrifugal pump may cause inconvenience in the installation of water pipes due to the high pipe height.
