Specific implementation of the present utility model：
1. sealing structure 6, devises water-cooling structure, when fluid temperature is more than 80 degree, sealing structure 6 need to add cooling
Water, cooling water can not only play cooling, thermal insulation, protect bearing, extend the effect of bearing service life, and cooling water can also rush
Cooling mechanical seal sealing surface is washed, even if anticorrosive anti-wear desulfurization pump stops or dallied in a short time, mechanical seal will not also be damaged
It is bad；The dynamic and static ring material of mechanical seal uses pressureless sintering carborundum, and carborundum has a wear-resisting, corrosion resistant, and self-lubricating property is good
Feature, machine envelope service life is more than the three times of common machine seal structure；
2. impeller 5 is double shrouded wheel, import choma is tapered fitted seal by traditional circumference seam seal en-hancement,
The front and rear cover plate of impeller 5 is respectively designed with back blade, and the first back blades 5-1 can prevent big particle from entering impeller 5 and being bored with liner plate 8
In the gap 9 that type coordinates, the abrasion between impeller 5 and liner plate 8 is reduced；Second back blades 5-2 can reduce axial force, stop big
Grain enters mechanical seal position, also reduces the pressure at mechanical seal position simultaneously, makes sealing effectiveness more reliable；
3. the pump housing 2 by traditional overall structure be improved to front pump cover 7 be usually coated plate 8 and pump housing volute body be coupled to one it is whole
Body, traditional pump housing 2 use the import choma of impeller 5 and the entrance choma seam circumference fitted seal of the pump housing 2, and fit clearance is smaller,
Under the drive that impeller 5 rotates at a high speed, the particle in slurries with very fast with the relative velocity of the porch of the pump housing 2, and wear extent with
The movement velocity of particle it is cube directly proportional, therefore the porch of the pump housing 2 needs to bear abrasion most strong in all flow passage components,
Frequently appear in the conveying slurries shorter time, it is worn out to even result in the whole pump housing 2 with regard to heavy wear for the inlet location of the pump housing 2
The phenomenon scrapped；Structure after improvement, the service life of the pump housing 2 is substantially increased, is changed first with original seam circumference
Enter for the taper fit on impeller 5 and liner plate 8, add the length of fit clearance, improve the efficiency of pump, also allow for regulation and coordinate
The size in gap, next to that the thickness of liner plate 8 reaches more than 35mm, the wearability of the whole pump housing 2 is substantially increased, even if liner plate
8 are worn, and only need to change a liner plate 8, greatly reduce maintenance cost, simultaneously because liner plate 8 has extremely strong wearability, ensure
Impeller 5 also further extends the service life of impeller 5, enters one with the prolonged smooth of its matching part and completely
Step improves the wearability of anticorrosive anti-wear desulfurization pump；
4. the outlet of the pump housing 2 is improved to lateral exit by traditional central exit, the outlet of the pump housing 2 is set to be located at runner tangent line side
To greatly reducing impact and abrasion of the slurries to outlet flow position；The thickness of the pump housing 2 is added in addition, and average thickness reaches
More than 25mm, it is sufficient to bear the wear-resisting needs of pump chamber pressure and slurries.
Above-described embodiment is only intended to clearly illustrate the description that the utility model is made, and not to the limit of embodiment
It is fixed, to those of ordinary skill in the art, other various forms of changes can also be made on the basis of the above description
Or change, there is no necessity and possibility to exhaust all the enbodiments, and the obvious change thus amplified out
Or among changing still in the scope of protection of the utility model.
