Description
Technical field
The utility model is related to a kind of slurry pump impeller, more particularly to a kind of inserted slurry pump impeller.
Background technology
Pulp pump is for conveying one of main tool of solid-liquid mixed slurry liquid containing certain abrasive particle medium.Due to
The presence of abrasive particle medium in liquid, so must have to the material used in the impeller of pump, pump case and other flow passage parts very high
Wearability requirement.Now generally using high-chromium alloy (such as A05 systems and Cr27), also paid pilot production makes slurry with polyurethane
Impeller of pump also needs to handle flow passage part using line with rubber or using stainless steel part to conveying the liquid with abrasion-proof corrosion-proof requirement.For
Meet wearability requirement, improve the service life, impeller integrally can not then avoid manufacture cost from increasing problem using high abrasion resisting material, adopt
Although relatively low with the impeller manufacture cost of conventional material, since the service life is shorter, frequent, use cost increase is replaced, simultaneously
Maintenance downtime can also increase.
Utility model content
In order to overcome the above-mentioned deficiencies of the prior art, the utility model provides a kind of inserted slurry pump impeller, to carry
High service life simultaneously controls manufacture cost.
Technical solutions of the utility model are as follows：A kind of inserted slurry pump impeller, it is described including impeller body and inserts
Impeller body includes wheel disc and is arranged at the blade of sheave surface, and the inserts is dog-ear part, the first side of the inserts
Wall is fixedly connected with blade, and the wheel disc between the second sidewall of the inserts and two adjacent blades is fixedly connected, described
Inserts dog-ear lateral surface is bonded with the impeller body.
Further, the wheel disc between two adjacent blades is equipped with groove, and the second sidewall of the inserts is set
It is placed in the groove.
Further, the inner surface of the second sidewall of the inserts is flushed with sheave surface.
Further, whole sides of the first side wall covering blade of the inserts, the second of the inserts
Side wall covers at least half of the sheave surface between two adjacent blades.
Preferably, the wheel disc and blade are integrally formed, and the inserts is used with blade and inserts with wheel disc
Pressure welding connects.
Preferably, the material of the impeller body is ZG40Cr5Mo.
Preferably, the material of the inserts is YG8 either YG15 or white steel.
The advantages of technical solution provided by the utility model, is：
This inserted slurry pump impeller is by the way that in impeller working face, i.e. the main region with abrasive particle collision friction inlays hardness
The higher alloy components with wearability, improve impeller working life, and the more single middle chromium wear-resistant steel material impeller of service life improves
It 2-3 times, greatly improves work efficiency, reduces line service.
Description of the drawings
Fig. 1 is the structure diagram of the inserted slurry pump impeller of the utility model.
Fig. 2 is inserts structure diagram.
Specific embodiment
With reference to embodiment, the utility model is described in further detail, but not as the restriction to the utility model.
It refer to shown in Fig. 1 and Fig. 2, by taking the impeller of prismatic blade as an example, inserted slurry pump impeller includes 1 He of impeller body
Inserts 2, impeller body 1 include wheel disc 3 and the blade 4 for being arranged at 3 surface of wheel disc, and impeller body 1 is integrally formed, all
Blade 4 is plane prismatic blade, and along the radial arrangement of wheel disc 3.3 surface of wheel disc between two neighboring blade 4 offers sector
Groove 5, a side of groove 5 is the boundary of blade 4 and wheel disc 3, another side of groove 5 is two neighboring blade 4
Between angle bisecting line.Chromium wear-resistant steel material ZG40Cr5Mo during impeller body 1 uses, is cast using hot investment casting,
The annealed processing of casting carries out metalworking processing to blade 4 and groove 5, and makees dynamic balance treatment to integral wheel body 1.Finally
It is heat-treated, hardness is maintained at middle position need not be excessively high, it is desirable that there is preferable toughness to have certain wearability concurrently.
Inserts 2 is the dog-ear part with the first side wall 6 and second sidewall 7, wherein 6 shape of the first side wall and 4 shape of blade
Shape is identical, and 7 shape of second sidewall is identical with 5 shape of groove.The outer surface 8 of the first side wall 6 fits with blade 4, second sidewall 7
Then it is embedded in groove 5.The thickness of second sidewall 7 and the deep equality of groove 5 so that after inserts 2 is embedded in, the of inserts 2
The inner surface 9 of two side walls 7 is flushed with 3 surface of wheel disc.Inserts 2 can determine material according to use condition, when uniform particle granularity
YG8 or YG15 can be selected in below 1mm, can be selected when particle size differs (such as granularity is 0.3~2mm) as white steel is contour
Fast instrument steel.
Pressure welding is carried out using copper-based wlding between inserts 2 and impeller body 1.Impeller body 1, inserts 2 is preheated
Pressure welding is carried out after processing on special press welder to be integrally formed.Impeller after shaping carries out isothermal holding, and start again
Blance test, to be conducive to improve the overall operation stationarity of pump.
