Description
Technical field
The present invention relates to a kind of centrifugal pump, especially relate to it is a kind of apply to conveying cleaning or containing a small amount of solid
Grain, solid content≤30%, viscosity≤300CP, temperature are -20 DEG C -- a kind of chemical centrifugal pump of 300 DEG C of liquid mediums.
Background technology
Slurry chemical pump is a kind of one step single sucking (axially suction, radially discharge) corrosion resisting centrifugal pump, is widely used in stone
The industries such as oil, chemical industry, automobile making, non-ferrous metal, food, power station, metallurgy, papermaking, pharmacy, mainly for delivery of it is various acid,
Alkali, salt etc. are corrosive medium, can also convey cleaning or containing a small amount of solid particle, and solid content≤30%, viscosity≤
300CP, temperature are -20 DEG C -- 300 DEG C of liquid mediums.According to the relevant Searches of Patent Literature, in general one step single sucking corrosion resistant at present
Although losing centrifugal pump short time interior energy to meet to require, the excessively stream part of this pump is easy to wear after long-term use, easily occurs
Leakage phenomenon, its service life is very short, and the production cost of factory can increase substantially.
The content of the invention
It is an object of the invention to provide a kind of brand-new mentality of designing, designs a kind of can meet after long-term use not
Easily there is the one step single sucking corrosion resisting centrifugal pump of leakage phenomenon.
The object of the present invention is achieved like this：A kind of high efficiency slurry chemical pump includes the pump housing, bearing, impeller, pump shaft, pump
Lid, is provided with inlet and outlet, the pump housing links together with described pump cover, and the described pump housing is on the described pump housing
Between support fixed with bearing housing body phase, described pump shaft is fixed on by bearing in described bearing housing；In the pump shaft
One end be fixed with impeller, described impeller is just in the cavity between the pump housing and pump cover；Set between pump cover and pump shaft
There is seal assembly, it is characterised in that：Pump housing wear ring is provided with position of the described pump housing close to impeller, in the impeller
Relevant position is provided with impeller abrasion-proof ring.
The present invention has the following advantages that compared with prior art：
1. because the excessively stream part of pump is provided with, pump housing wear ring, impeller abrasion-proof ring be not easy to wear, and its service life is carried significantly
Height, the production cost of factory can be greatly lowered.
2. the pump shaft bolster lower sideband has cooling-water duct, when medium temperature reaches 180 DEG C -- bearing bracket stand leads at 300 DEG C
Water cooling, improve the service life of pump.
3. there is adjustment structure in impeller clearance outside pump, pump Effec-tive Function can be maintained for a long time.
4. impeller is reduced during unshrouded impeller conveying slurry containing crystal after efficient to act on crystal fracture, it is small conveying
Flow high-lift, impeller is not easily blocked during pulp density higher medium.
5. the rear portion of impeller is open type, without back blade with regard to the pressure of shaft seal cavity can be reduced, crystal is prevented, particle enters axle
Position is sealed, improves the service life of seal.
6. shaft seal structure has packing seal, mechanical seal, not easy to wear when conveying easily blocks, has the slurry of abrasion, make
The pump scope of application is wider, and service life is longer, and operating cost is lower.

Embodiment
Embodiment：From figure 1 it appears that a kind of high efficiency slurry chemical pump includes the pump housing 1, bearing 8 and 10, impeller
5th, pump shaft 11, pump cover 2, inlet and outlet being provided with the described pump housing 1, the pump housing 1 links together with described pump cover 2,
The described pump housing 1 is fixed by intermediate support 15 and the phase of bearing housing 9, and described pump shaft 11 is fixed on by bearing 8 and 10
In described bearing housing 9；Impeller 5 is fixed with one end of the pump shaft 11, described impeller 5 is just in the pump housing 1 and pump
In cavity between lid 2；Seal assembly is provided between axle sleeve 13 on pump cover 2 and pump shaft 11, it is characterised in that：Described
The pump housing 1 be provided with pump housing wear ring 3 close to the position of impeller 5, impeller abrasion-proof is provided with the relevant position of the impeller 5
Ring 4.
In order that pump reduces impeller when conveying slurry containing crystal and crystal fracture is acted on, and soared in conveying low discharge
Journey, impeller is not easily blocked during pulp density higher medium, and described impeller 5 is using unshrouded impeller after efficient.
