Abstract
The utility model relates to a single-stage single-suction type chemical centrifugal pump which comprises a pump body and an impeller component, wherein a bracket is connected on the outer surface of the pump body, a pump shaft is horizontally arranged at the center position inside the bracket, the impeller component is arranged at the inner end of the pump shaft and is locked on the pump shaft through an impeller nut, and a sealing ring is arranged on the inner wall face of the pump body and on the periphery of the impeller component. Meanwhile, a shaft sleeve is arranged on the periphery of the middle section of the pump shaft, and a water sealing ring is located on one side of the shaft sleeve. The single-stage single-suction type chemical centrifugal pump has the advantages of simplifying structural components, improving sealing performance, saving maintenance cost, and being capable of conveying media with high temperature of below 300 DEG C, wide in application range, capable of conveying the media with the high temperature of below 300 DEG C through a double mechanical sealing and cooling device, wide in the range of performance, high in efficiency and convenient to maintain, suitable for industries such as chemical industry, oil, metallurgy, papermaking, food, pharmacy and synthetic fibers and the like.
Description
Technical field
The utility model relates to a kind of centrifugal pump, relates in particular to a kind of one step single sucking formula chemical centrifugal pump.
Background technique
That centrifugal pump has is vertical, horizontal, single-stage, multistage, single suction, double suction, various ways such as self-priming.Its main working principle is the performance of object inertia, impeller is by the pump shaft driven rotary, to being positioned at interlobate fluid acting, fluid is subjected to action of centrifugal force, thrown to the periphery by the impeller center, pump case compiles the liquid of being dished out between each blade, and the direction that these liquid enlarge gradually along the scroll casing shape passage in shell flows, make the kinetic energy of fluid be converted into static energy, reduce energy loss; Rely on impeller to rotate at a high speed, force the liquid at impeller center to be set aside with very high speed, thereby be formed centrally low pressure in impeller, therefore the liquid in the Lower tank sucted continuously.Chemical pump wherein is widely used in the every field of chemical industry, for example stainless steel chemical industry pump, fluoroplastic chemical pump, chemical industry magnetic drive pump, chemical industry self-priming pump etc.; These chemical pumps are widely used in chemical industry, metallurgy, pharmacy, change into industries such as paper tinsel, and important purposes is all arranged.But, because existing a lot of products adopt single sealing configuration and sealing effect relatively poor, can't carry the high-temperature medium below 300 ℃; Simultaneously, cooperating between the pump housing, impeller and the pump cover is too complicated, wherein also is embodied in place mat, sealing and connection part between these main body parts, and these all impel safeguards inconvenience, influences operational efficiency to a great extent.Therefore, at above aspect, need reasonably improve prior art.
Summary of the invention
At above defective, the one step single sucking formula chemical centrifugal pump that the utility model provides a kind of assembly that simplifies the structure, has improved sealability, saved maintenance cost, can carry high-temperature medium below 300 ℃, application area is wider is to solve many deficiencies of prior art.
For achieving the above object, the utility model is by the following technical solutions:
A kind of one step single sucking formula chemical centrifugal pump, comprise the pump housing, impeller assembly, described pump housing outer surface connects carriage and this carriage inside center position is horizontally disposed with pump shaft, be positioned at that the pump shaft inner end is provided with impeller assembly and this impeller assembly lock onto on the pump shaft by impeller nut, the pump housing internal face that is positioned at the impeller assembly periphery is provided with seal ring; Simultaneously, described pump shaft intermediate section periphery arranges axle sleeve and is positioned at this axle sleeve one side and is provided with seal cage.
Correspondingly, be positioned on the pump shaft of impeller nut adjacent regions and be with drag washer, described axle sleeve arranged outside gland.
The beneficial effect of one step single sucking formula chemical centrifugal pump described in the utility model is: by the position annexation of the pump housing, impeller part, three main body parts of pump cover rationally is set, simultaneously fitted seal ring and seal cage, the assembly that simplifies the structure, improved sealability, saved maintenance cost, can carry high-temperature medium below 300 ℃, application area is wider; Can be by the high-temperature medium of double mechanical seal cooling unit conveying below 300 ℃, have that performance range is wide, efficient is high, " three change " level height, characteristics such as easy to maintenance, be applicable to that industries such as chemical industry, oil, metallurgy, electric power, papermaking, food, pharmacy and synthetic fiber are for delivery of various corrosive ideal products that do not allow pollution medium.
