Abstract
The utility model relates to a chemical pump, particularly a fused salt pump used for conveying high-temperature fused salt media in chemical plants. The utility model comprises a motor, a pump body, an impeller, a pump shaft, a bearing box, a middle rack and a base plate, wherein the pump body is connected with the base plate; one end of the pump shaft is fixed to the bearing box by the bearing, and the other end is fixed with the impeller; the bearing box is connected with the base plate by the middle rack. The utility model is characterized in that the pump body is in a structure with double outlets which are arranged symmetrically. As a result, when the media is conveyed, the radial force generated on the pump shaft can be balanced mutually and the abrasion of the pump shaft and the sealing element can be reduced. Consequently, the service life of the pump is extended. Not only the middle rack and the bearing box are provided with water-cooling channels, but also the pump shaft between the middle rack and the bearing box is provided with a blade for adding a wind cooling system, so that the temperature for installing a bearing of the pump shaft can not be influenced by high-temperature media.
Description
Technical field: the utility model relates to a kind of chemical pump, particularly relates to a kind of chemical plant that is used for and carries high temperature chemical material medium, in particular for carrying a kind of chemical centrifugal pump of high-temperature molten salt medium.
Background technique: pump for liquid salts is a kind of chemical centrifugal pump, is mainly used in the chemical plant and carries high temperature chemical material medium, in particular for conveying high-temperature molten salt medium, as is used for Melamine and fluorine chemical project.Medium allows maximum temperature at 540 ℃.At present, at home and abroad the pump for liquid salts that adopts of market all is to adopt that pump housing single suction is single to go out structure, and the pump housing adopts the I and II water-cooled, there is following shortcoming in use: 1. go out structure owing to the employing single suction is single, the radial force that is produced when fed sheet of a media is bigger, use the sealability that can influence axle over a long time, thus the working life of having reduced pump; Since the fused-salt medium temperature of carrying up to 500 ℃, though pump has adopted the I and II water-cooled, but pump is after continuous operation over a long time, the temperature that the pump shaft bearing is installed still can be subjected to the influence of high temperature media and slowly rising, can be reduced greatly the working life of bearing, increased the maintenance number of times of pump, brought unnecessary economic burden to enterprise.
Summary of the invention: the purpose of this utility model just provides a kind of new design idea, designing a kind of radial force that can satisfy when the long-term delivery high temperature media pump shaft is reduced to minimum, can make again the influence that the pump shaft bearing is not subjected to high temperature media is installed, with the pump for liquid salts in working life of improving pump.
The purpose of this utility model is achieved in that a kind of pump for liquid salts comprises motor, the pump housing, impeller, pump shaft, bearing housing, middle frame, base plate, on the described pump housing, be provided with import and outlet, this pump housing and described base plate link together, an end of described pump shaft by bearing fixing on described bearing housing; The other end at described pump shaft is fixed with impeller, and described impeller is positioned at the cavity of the pump housing; Described bearing housing links together by middle frame and described base plate; It is characterized in that: the double outlet structure of the described pump housing for being symmetrically distributed.
The utility model compared with prior art has following advantage:
1. because the described pump housing is the double outlet structure that is symmetrically distributed, when fed sheet of a media, the mutual balance of radial force meeting that is produced on pump shaft reduces the wearing and tearing meeting of pump shaft and sealed member greatly, thereby is improved the working life of pump like this.
2. because described middle frame is provided with the one-level water-cooling channel, bearing housing is provided with the secondary water-cooling channel, and the pump shaft between middle frame and the bearing housing is provided with fan blade, to increase air cooling system, structure has more rationality, improves the stability and the working life of pump.
Description of drawings: Fig. 1 is the structural representation of pump for liquid salts described in the utility model
1. motor 2. bearings 3. bearing housings 4. one-level water-cooling channels
5. middle frame 6. base plates 7. fan blades 8. secondary water-cooling channels
9. export 13. imports of 10. pump shafts, 11. impellers, 12. pump housings
Embodiment: as can be seen from Figure 1, a kind of pump for liquid salts comprises motor 1, the pump housing 12, impeller 11, pump shaft 10, bearing housing 3, middle frame 5, base plate 6, on the described pump housing 12, be provided with import 13 and outlet 9, this pump housing 12 links together with described base plate 6, and an end of described pump shaft 10 is fixed on the described bearing housing 3 by bearing 2; The other end at described pump shaft 10 is fixed with impeller 11, and described impeller 11 is positioned at the cavity of the pump housing 12; Described bearing housing 3 links together by middle frame 5 and described base plate 6; It is characterized in that: two outlet 9 structures of the described pump housing 12 for being symmetrically distributed.
Can not be subjected to the influence of high temperature media for the temperature that makes pump that the bearing 2 of pump shaft 10 is installed after working over a long time, to improve the working life of pump, not only described middle frame 5 is provided with secondary water-cooling channel 8, bearing housing 3 is provided with one-level water-cooling channel 4, and the pump shaft 10 between middle frame 5 and the bearing housing 3 is provided with fan blade 7, to increase air cooling system.
