Vertical high-flow high-efficiency water pump with all-welded structure

Abstract

The invention discloses a vertical high-flow high-efficiency water pump with an all-welded structure. The vertical high-flow high-efficiency water pump comprises a shell and an inner cylinder, wherein annular support plates are transversely arranged in the inner cylinder; axial support plates are arranged on the inner wall of the inner cylinder; a sheathing pipe is arranged inside the inner cylinder; an outer shell elbow is arranged inside the shell; the right side of the outer shell elbow stretches out of the shell; bearings are arranged at the top, the middle part and the bottom of the inner cylinder; an annular reinforcing plate is arranged above the middle bearing; an axial reinforcing plate is arranged between the annular reinforcing plate and the bearing; flanges are arranged at two ends of the top and the bottom of the shell and are fixedly connected to the shell. The vertical high-flow high-efficiency water pump with the all-welded structure has the advantages of reasonable structure design, low vibration, high efficiency and convenience in mounting and debugging, and can be widely popularized and applied.

Description

technical field [0001] The invention belongs to the technical field of water pumps, and in particular relates to a vertical large-flow high-efficiency water pump with an all-welded structure. Background technique [0002] With the increasing scale of social production in our country, the demand for water resources is increasing, and the existing water energy is limited. Moreover, there are great differences in water resources and demands between the east and west, and the north and south. At present, , my country is in an important period of modernization. In order to meet the needs of social production and people's life for water resources, and to ensure the safety of people's lives and property, my country has entered a large-scale water conservancy project development stage. Water conservancy projects such as energy storage projects, thermal power nuclear power and other large-volume cooling, factory production water, agricultural irrigation, and residential water use all r...

Problems solved by technology

[0003] The large-flow water pumps widely used now include volute type, vertical casting type and partial welding type, etc. Due to many shortcomings, for example, the volute type is not suitable for high water head conditions, and the large-sized casting type The cost of casting mold equipment is high and the quality of castings is difficult to guarantee. For water pumps with large flow and large height difference, local welding is more commonly used, but water pumps with welded structures generally have poor rigidity, large vibration, high noise, low efficiency, Installation and debugging are difficult to fine-tune and other problems. For this reason, a new type of vertical large-flow high-efficiency water pump is urgently needed to replace the shortcomings of the existing models.
