Abstract
The invention relates to a horizontal-type radial subdivision volute-type dual-cylinder pump which comprises a bearing component, a pulling plate, a driving section pump cover, a primary impeller, a volute body, cylinder bodies, a secondary impeller, a non-driving end pump cover, a pump shaft and a fastener. The cylinder bodies are arranged between an inlet and the volute body and between the volute body and an outlet through the pulling plate, the fastener, the driving section pump cover and the non-driving end pump cover. The primary impeller and the secondary impeller are arranged in a face-to-face mode in the axial direction. A suction chamber is located between the two impellers. The same axial length is occupied by a primary transition flow pass and a secondary flow pass. A delivery chamber is of a fluid director structure. The horizontal-type radial subdivision volute-type dual-cylinder pump has the advantages of being compact in structure, convenient to install and maintain, high in operating efficiency and the like, and can be applicable to the high-temperature, high-pressure, flammable, combustible, poisonous and harmful working environment for conveying granular media.
Description
Technical field
The present invention relates to a kind of centrifugal pumping apparatus, especially a kind of horizontal radial subdivision scroll casing type double shell pump that is applicable to carry large flow High Temperature High Pressure, inflammable and explosive, poisonous and harmful, contains granule medium.
Background technique
The large flow bearings at both ends of using at present supports, radially single-stage, two-stage or three grades of centrifugal pumps of subdivision, volute type structure, all adopt mono-hull cast structure, when entrance is under ultrahigh pressure the working condition with high temperature, Safety performance significantly declines, and affects the normal use of pump.When maintenance, bearings at both ends parts must be removed in advance simultaneously, be had the problems such as maintenance and installation inconvenience.
Summary of the invention
The object of this invention is to provide under a kind of, entrance hyperbaric environment large at flow the higher maintenance of Security horizontal radial subdivision scroll casing type double shell pump easily.
For achieving the above object, horizontal radial subdivision scroll casing type double shell pump of the present invention comprises bearing part, arm-tie, driving section pump cover, impeller chopped-off head, volute casing, cylindrical shell, impeller secondary, anti-drive end pump cover, pump shaft, fastening piece, wherein by arm-tie, fastening piece, driving section pump cover, anti-drive end pump cover, cylindrical shell is arranged between entrance and volute casing, volute casing and outlet, impeller chopped-off head and impeller secondary arrange vertically face-to-face.Delivery chamber adopts flow-guiding device structure.
Adopt after said structure, owing to driving section pump cover, anti-drive end pump cover, cylindrical shell to be independent forging molding, reliable performance, bearing capacity is high, can meet the working environment of large flow, high pressure.Impeller chopped-off head and impeller secondary arrange and can eliminate axial force face-to-face vertically.Suction chamber takies identical axial length to secondary transition runner between two impellers and by one-level, can improve fineness ratio, compact structure, and rotor operation is more reliable.When the pump housing keeps in repair, arm-tie and fastening piece can be removed, can in the situation that not dismantling import and export pipeline, pump housing internal rotor integral body be extracted out by anti-drive end, installation and maintenance are convenient.
As a further improvement on the present invention, bearing part adopts the sliding shoes of pressure lubrication to join thrust-bearing.Under the powerful operating conditions of applicable large flow high-lift, use.
Advantage of the present invention is: compact structure, and installation, maintenance is convenient, the medium that can carry High Temperature High Pressure, inflammable and explosive, poisonous and harmful, contains particle, operational efficiency is high.
Accompanying drawing explanation
Fig. 1 is the overall structure schematic diagram of horizontal radial subdivision scroll casing type double shell pump of the present invention.
Embodiment
As shown in Figure 1, horizontal radial subdivision scroll casing type double shell pump of the present invention comprises bearing part 1, arm-tie 2, drive section pump cover 3, impeller chopped-off head 4, volute casing 5, cylindrical shell 6, impeller secondary 7, anti-drive end pump cover 8, pump shaft 9, fastening piece 10, one-level is to secondary runner 12, delivery chamber 11, fluid director 13, wherein pass through arm-tie, fastening piece, drive section pump cover, anti-drive end pump cover is arranged at entrance and volute casing by cylindrical shell, between volute casing and outlet, impeller chopped-off head and impeller secondary arrange vertically face-to-face, suction chamber 14 takies identical axial length to secondary transition runner between two impellers and by one-level, delivery chamber adopts flow-guiding device structure.Bearing part adopts the sliding shoes of pressure lubrication to join thrust-bearing.Owing to driving section pump cover, anti-drive end pump cover, cylindrical shell to be independent forging molding, reliable performance, bearing capacity is high, can meet the operating conditions of large flow, high pressure.Impeller chopped-off head and impeller secondary arrange and can eliminate axial force face-to-face vertically, without balanced controls.Suction chamber takies identical axial length to secondary transition runner between two impellers and by one-level, can improve fineness ratio, compact structure, and rotor operation is more reliable.During maintenance, arm-tie and fastening piece can be removed, can in the situation that not dismantling import and export pipeline, pump housing internal rotor integral body be extracted out by anti-drive end, easy to maintenance, save the installation and maintenance time.
The present invention has the features such as bulk is little, operational efficiency is high, long service life.Be applicable to High Temperature High Pressure, inflammable and explosive, carry poisonous and harmful, have the working environment of granule medium.
