Embodiment Construction

[0013] Below in conjunction with accompanying drawing, the present invention is described in further detail:

[0014] Such as figure 1 Shown, the present invention double barrel segmental horizontal multistage centrifugal pump is composed of driving end bearing part 1, cylinder body 2, suction box body 3, guide vane middle section 4, impeller 5, pump shaft 6, balance pipe part 7, pump Cover 8, balance mechanism 9, drain pipe 10, non-drive end bearing part 11 and other components, wherein the cylinder 2-1 in the sealed box located at the end of the drive-end bearing part is welded to the end plate 2-2 of the sealed box, The end plate 2-2 of the sealed box is welded with the cylinder (such as figure 2 shown); the guide vane and the middle section of the pump adopt an integrated structure, and the positive guide vane and the suction box are both open structures (such as image 3 shown). A shaft head oil pump 12 is connected to the end of the non-drive end bearing part (such a...

Abstract

The invention relates to a double-cylinder sectional type horizontal multilevel centrifugal pump. The double-cylinder sectional type horizontal multilevel centrifugal pump comprises a drive-end bearing part, cylinders, a suction box, a guide vane middle section, impellers, a pump spindle, a balanced pipe part, a pump cover, a balancing mechanism, a drain pipe, a non-drive-end bearing part, wherein the inner cylinder of a sealing box located at the terminal end of the drive-end bearing part is fixedly connected to the end plate of the sealing box; the end plate of the sealing box is fixedly connected to the cylinders. Guide vanes in the pump and the middle section are of an integral structure; the positive guide vanes and the suction box are of an open structure. The double-cylinder sectional type horizontal multilevel centrifugal pump is compact in structure, more convenient to install, maintain and detect, reliable in operation and high in efficiency, is suitable for transporting products of petrochemical engineering and other chemical industries, high-temperature and high-pressure mediums and mediums with corrosiveness or flammable and combustible characteristics, can serve as a big-flow high-temperature and high-pressure boiler water supply pump and a diesel hydrogenating and feeding pump.

Description

technical field [0001] The invention relates to a centrifugal pump, in particular to a double-cylinder segmented horizontal multistage centrifugal pump used for transporting high-temperature, high-pressure, corrosive or inflammable and explosive medium. Background technique [0002] At present, the double-casing horizontal multistage pump adopts the split structure of the guide vane and the middle section, and the suction box in the pump adopts a closed structure. If forced lubrication is implemented, the lubricating oil station is directly used to supply oil to the lubricating points such as the pump bearings. The above-mentioned structure is lacking in the stability of pump operation and energy saving. The problem is particularly prominent under the working conditions of high temperature and high pressure, high speed, large flow and high head. Contents of the invention [0003] The object of the present invention is to provide a double cylinder segmented horizontal mult...
