Abstract
A sludge liquor pump comprises a pump body, a shaft, impellers and a pump cover. The impellers are arranged at the front end of the shaft of the submerged pump, a first mechanical sealing device is arranged at the connecting position of the shaft behind the impellers with the pump cover, a second mechanical sealing device is arranged behind the first mechanical sealing device and between a spindle and a lower bearing block, and an oil chamber used for cooling is further arranged between the second mechanical sealing device and the lower bearing block. The method of respectively arranging two sets of bearings on the spindle on the lower portion of a bottom plate can greatly lower noise of use of the submerged pump, and prolong the service life of the submerged pump.
Description
Technical field: the utility model relates to the pump that uses in a kind of desulfurizing industrial fume device, particularly relates to a kind of slurry pump that uses under liquid.
Technical background; In the desulfurizing industrial fume device, generally all need liquid is adopted slurry pump discharge under the liquid from melt pit and case jar.But the present Under Water Pumps that adopts, it is short all to exist working life, and inefficiency is not corrosion-resistant, and many defectives such as noise is big, has increased the maintenance cost and the burden of enterprise virtually.
Summary of the invention: the purpose of this utility model, to provide slurry pump under a kind of liquid exactly, can effectively overcome the existing defective of above Under Water Pumps.The purpose of this utility model is achieved in that slurry pump is by the pump housing, axle, and impeller, pump cover is formed, and it is characterized in that: the front end at the Under Water Pumps axle is provided with impeller, and the axle behind the impeller has adopted the first road mechanical seal device with the joint of pump cover; Behind the first road mechanical seal device, be provided with the second road mechanical seal device between main shaft and the step, also be provided with the grease chamber that cooling is used between described second road mechanical seal device and the step; On the main shaft of base plate bottom, also be provided with two groups of bearings respectively; Also be provided with two groups of bearings on the upper spindle of base plate respectively; Above described bearing, also be provided with coupling and motor cabinet; Side in the import of pump housing lower end is provided with elbow, and described elbow links to each other with last drain pipe with following drain pipe.The utility model adopts the double mechanical seal structure, by oil cooling but, can effectively stop the corrosion of solution, simultaneously by on base plate to pump housing inside, many group bearings are set on the following main shaft can reduce the noise that Under Water Pumps uses greatly, prolong the working life of Under Water Pumps.
Description of drawings: Fig. 1 is a structural representation of the present utility model;
Fig. 2 is a part structure for amplifying schematic representation of the present utility model;
1. drain pipe 24. base plates 25. machinery oil on 22. times drain pipes 23. of 2. 3. impellers of the pump housing, 4. pump covers, 5. mechanical seal 6. grease chambeies, 7. step 8. mechanical seals, 9. bearing 10. lower support pipes, 11. middle bearing bracket 12. bearings, 13. upper support pipe 14. bearing suppories, 15. bearing 16 bearing housings, 17. lower bearing gland 18. locknuts, 19. coupling 20. motor cabinets, 21. elbows
Specific implementation method: the utility model is described in further detail below in conjunction with accompanying drawing;
The utility model slurry pump is by the pump housing 1, axle 2, and impeller 3 pump covers 4 are formed, and it is characterized in that: the front end at Under Water Pumps axle 2 is provided with impeller 3, and the axle 2 behind the impeller 3 has adopted the first road mechanical seal, 5 devices with the joint of pump cover 4; Behind the first road mechanical seal, 5 devices, be provided with the second road mechanical seal, 8 devices between axle 2 and the step 7, also be provided with the grease chamber 6 that cooling is used between the described second road mechanical seal, 8 devices and the step 7; On the axle 2 of base plate 24 bottoms, also be provided with two groups of bearings respectively; On the axle 2 on base plate 24 tops, also be provided with two groups of bearings respectively; On described bearing 12, also be provided with coupling 19 and motor cabinet 20; Side in the pump housing 1 lower end import is provided with elbow 21, and described elbow 21 links to each other with last drain pipe 23 with following drain pipe 22.During concrete enforcement, motor drives the axle high speed rotating of Under Water Pumps by coupling, owing to be provided with many group bearings respectively on main shaft, makes the Under Water Pumps running steadily, can not produce very big noise.Simultaneously be provided with double-deck mechanical seal, but can reduce the corrosion of solution effectively pump body structure by oil cooling at the middle part of Under Water Pumps main shaft.The utility model is from the suction port aspect, for being rotated counterclockwise the pump housing, pump cover is taken over bearing support, the bearing support support constitutes one mutually, is fixed on the base plate, and the integral body of pump directly engages with container by base plate, the last fulcrum of axle, intermediate support and lower fulcrum all adopt bearing, and impeller adopts the beginning impeller, can be directly with solution through elbow, by following drain pipe, last drain pipe is discharged to the top of base plate.
