Abstract
The utility model discloses a slag pool pump applicable to chemical fluid transferring less than 40 percent of solid content. The pump comprises a pump body, an impeller, a pump shaft, a front cover and a bearing box body, wherein one end of the pump body is connected together with the front cover; the other end of the pump body is fixed with the bearing box body; a rear pump cover is fixed on the pump body; the pump shaft is fixed in the bearing box body; the impeller is fixed at one end of the pump shaft; and an inner pump body is fixed in the pump body. The utility model adopts the double-layered pump body technology, namely the outer pump bears pressure while the inner pump bears the water-coal-slurry scouring, so that the pump not only bears pressure but also resists wear, the service life of the pump is prolonged, and the maintenance cost of the pump is reduced. The slag pool pump can be mainly applicable to coal chemical industries like coal liquefaction, coal replacing oil, coal making oil and the like for transferring water-coal-slurry.
Description
Technical field:
The utility model relates to a kind of pump, relates in particular to be used in carry solid content less than 40% chemical industry fluid slag bath pump.
Background technique:
Along with the develop rapidly of World Economics, oil shortage has become the bottleneck of economic development, because China is petroleum import big country, so country is advocating and utilizes other energy to replace oil.China is a big coal country, and coal resource is abundanter, and National Development and Reform Committee proposes to adopt coal liquefaction, coal for replacing oil and coal system wet goods project to substitute oil, to alleviate the pressure of oil.And the slag bath pump is mainly used coal liquefaction, coal for replacing oil and coal system wet goods Coal Chemical Industry industry transporting water coal slurry, contains the buck and the Cl of 2%-10% solid content in its medium

-Solid in the form of sheets, diameter is about 10mm.The technical performance index of pump requires: design pressure≤12MPa; Temperature≤300 ℃; Rotating speed≤3000rpm.And need bear corrosion such as coal ash requirement, this pump requires the Rockwell hardness of wearing piece about 58-62, and the pump housing also need bear the requirement of High Temperature High Pressure, according to the relevant Searches of Patent Literature, general one step single sucking chemical centrifugal pump does not reach this requirement at all at present, even though adopt this chemical centrifugal pump can meet the demands in the short time, leakage phenomenon appears in this pump easily, its working life is very short, and the cost of production of factory can increase substantially.
The model utility content:
The purpose of this utility model just provides the wear-resisting slag bath pump of a kind of novel high-pressure, it can satisfy pump and keep not having leakage when the arbitrary medium of the medium-term and long-term conveying of Coal Chemical Industry High Temperature High Pressure, can satisfy high reliability, high stability and flexible tracing ability under high pressure again.
The purpose of this utility model is achieved in that a kind of slag bath pump comprises the outer pump housing, impeller, pump shaft, protecgulum and bearing housing, the described outer pump housing one end and described protecgulum link together, the other end and described bearing housing fix, and are fixed with rear pump cover on the described outer pump housing; Described pump shaft is fixed in the described bearing housing; Be fixed with impeller at described pump shaft one end; It is characterized in that: described outer pump housing internal fixation has inner pump.
Liner plate and back backplate before being fixed with respectively on described protecgulum and the rear pump cover.
On described protecgulum, be fixed with the inlet lining.
The utility model compared with prior art has following advantage:
1. owing to adopt the double-layer pump body technology, the outer pump housing bears pressure, and inner pump bears washing away of water coal slurry, guarantees that pump had both born pressure, guarantees wear-resisting again.Prolong pump working life, reduced the pump maintenance cost.
2. owing to be provided with the inlet lining that high-abrasive material is made, can overcome like this and carry in the pump using process friction of high speed medium to protecgulum, the wear resistance and the working life of having improved protecgulum in the ingress of described protecgulum.
3. make preceding liner plate and back backplate owing to be fixed with high-abrasive material on described protecgulum and the rear pump cover respectively, can overcome like this and carry in the pump using process friction of high speed medium to protecgulum and rear pump cover, the wear resistance and the working life of further having improved protecgulum and rear pump cover.
