Embodiment

[0011] Can find out by accompanying drawing, the present invention adopts vertical structure, is made up of motor 1, stator part and rotor part. The stator part includes a pump body 2, a suction pipeline 3, a pressure water chamber 4, an outlet pipeline 5, a pump cover 6, an auxiliary impeller chamber 7 and a motor support 8. The motor bracket 8 is connected on the pump body 2 , the pump cover 6 is arranged on the upper end of the pressurized water chamber 4 , and the pump cover 6 is fixed on the motor bracket 8 . There is a sealing gland 9 on the upper part of the bottom plate of the motor support, and packing is used to seal between the sealing gland 9 and the pump shaft 11. When the outlet pressure is greater than 1Mpa, asbestos fiber-impregnated mica packing is used, and when the outlet pressure is greater than 1Mpa, it is less than 1Mpa or corrosive slurry is transported. When using asbestos fiber impregnated polytetrafluoroethylene filler. The pressurized water chamber ...

Abstract

A vertical slag pulp pump comprises a motor, a stator part and a rotor part. The stator part comprises a pump body on top of which disposed a pump head, a suction pipeline connected at the bottom of the pressure room, a pressure room fixed in the pump, a discharging pipeline connected with the outlet of the pressure room, a secondary vane room disposed on the top of the pressure room and an electric motor frame connected on the pump body. The rotor part comprises a coupling, a pump shaft, vanes and secondary vanes. The motor mounted on the electric motor frame connected with the pump shaft via the coupling. The vanes are fixed at the bottom of the pump shaft and the secondary vanes are mounted in the middle of the pump shaft and in the secondary vane room.

Description

technical field [0001] The invention relates to a slurry pump and belongs to the technical field of pump mechanical equipment. Background technique [0002] Slurry pump is a conveying equipment for solid-liquid mixed slurry in metallurgy, mining, building materials, electric power and other industries. At present, there are two structural forms of slurry pumps widely used. The first is the cantilever horizontal centrifugal slurry pump, which is used for backflow. It is composed of pump casing, guard plate, impeller, pump shaft, motor, inlet pipe and outlet pipe, etc. The impeller is installed on the pump shaft, and the motor drives the impeller through the pump shaft. Rotates to convey media. The whole pump body is in a horizontal structure, and the pump shaft is in a cantilever state. This kind of slurry pump occupies a large area, the pump bearing and impeller are easily damaged, maintenance is troublesome, and vibration noise is large. The other is a submerged slurry ...
