Description
Technical field
The utility model relates to water pump field, especially a kind of slurry pump special impeller.
Background technique
Impeller is one of critical piece in slurry pump, and it is made up of wheel disc and blade, and blades installation is on wheel disc, and wheel disc axle center is shaped with the mounting hole for connecting the pump housing.By vane rotary, slurry pump can to the material such as slurry conveyed or water in boring.When the material containing small particle of slurry pump conveying thickness, impeller High Rotation Speed is when carrying out material transferring, small particle has the impact force of increasing can to the blade of impeller, and after using a period of time, the wearing and tearing of partial blade are larger, even there is the fracture of local blade, in order to not affect the flow of slurry pump, just need to change impeller, and other blades are complete, entirety is scrapped and is made cost of production high, also wastes material simultaneously.
Model utility content
For above-mentioned deficiency of the prior art, the slurry pump special impeller that the utility model provides can after partial blade wearing and tearing/rupture after carry out the replacing of respective vanes.
For above-mentioned deficiency of the prior art, the technological scheme that the slurry pump special impeller that the utility model provides adopts is: comprise at least two pieces of mounting blocks, mounting blocks is at least provided with a slice and the integrated curved blade of mounting blocks; The both sides of the edge of mounting blocks are provided with one and the integrated joint of mounting blocks, and the height of joint is less than or equal to the height of blade; Be fixedly installed togather by installing some bolts on joint between mounting blocks, the curved flanges between all mounting blocks forms axis hole.
The beneficial effects of the utility model are: this impeller is fitted together by least two pieces of mounting blocks, in use, blade be subject to small particle impact force wearing and tearing or fracture after, that block mounting blocks that can take off damage is changed, need not all scrap by whole impeller, improve the working life of part mounting blocks, reduce cost of production, save material.

Embodiment
Below embodiment of the present utility model is described; so that those skilled in the art understand the utility model; but should be clear; the utility model is not limited to the scope of embodiment; to those skilled in the art; as long as various change to limit and in the spirit and scope of the present utility model determined, these changes are apparent, and all innovation and creation utilizing the utility model to conceive are all at the row of protection in appended claim.
The structural representation of slurry pump special impeller is shown with reference to figure 1 and Fig. 2, Fig. 1; Fig. 2 shows the structural representation of the mounting blocks 1 of slurry pump special impeller; As depicted in figs. 1 and 2, this slurry pump special impeller comprises at least two pieces of mounting blocks 1, mounting blocks 1 is at least provided with a slice and the integrated curved blade 2 of mounting blocks 1.In use, blade 2 be subject to small particle impact force wearing and tearing or fracture after, that block mounting blocks 1 that can take off damage is changed, and all need not scrap by whole impeller, improves the working life of part mounting blocks 1, reduce cost of production, saved material.
When the number of mounting blocks 1 arranges more, although can working life of augmenting portion blade 2, have a certain impact to the stressed of impeller entirety, preferred impeller be made up of three to four mounting blocks 1 for this reason.
The both sides of the edge of mounting blocks 1 are provided with one and the integrated joint 6 of mounting blocks 1, and the height of joint 6 is less than or equal to the height of blade 2.Be fixedly installed togather by installing some bolts 4 on joint 6 between mounting blocks 1, the curved flanges 7 between all mounting blocks 1 forms axis hole 5.
When the height of joint 6 is greater than the height of blade 2, the volume of the cavity installing impeller can be increased in slurry pump, increase the volume of slurry pump, the height of joint 6 is arranged to the height being less than or equal to blade 2, when ensureing slurry pump constancy of volume, the replacing of mounting blocks 1 in impeller can be realized again.
When the height of joint 6 is less than the height of blade 2, preferred each mounting blocks 1 is provided with one to two panels blade 2, after arranging like this, can ensures that slurry pump has enough large flow.
When the height of joint 6 equals the height of blade 2, two joints 6 be fixed together by bolt 4 form a slice prismatic blade, so often increase by one piece of mounting blocks 1 and will increase a slice prismatic blade.Ordinary water pump impeller selects six to eight blades 2, will increase a slice prismatic blade, so preferred each mounting blocks 1 only arranges a slice blade 2 owing to often increasing by one piece of mounting blocks 1.Because blade 2 interval on prismatic blade and mounting blocks 1 is arranged, effectively can improve flow and the lift index of water pump, improve water pump efficiency.
As shown in Figure 3, in an embodiment of the present utility model, the width of blade 2 is increased to its root gradually by top; After arranging like this, can ensure that blade 2 root is when being subject to small particle and impacting, blade 2 can not be truncated.The face side 21 of blade 2 is arranged to the cambered surface of an indent, the back side 22 of blade 2 is arranged to the cambered surface of an outwardly convex, and arranging rear face side 21 like this can to mud thrust, and the setting of back side 22 is more suitable for the streamlined of current.
The face side 21 of blade 2 is provided with the integrated stiffening rib 3 with blade 2, adopts in such a way, the impact force of the small particle that blade 2 carries can be increased, improve the working life of blade 2.
Although describe in detail embodiment of the present utility model by reference to the accompanying drawings, should not be construed as the restriction of the protection domain to this patent.In the scope described by claims, the various amendment that those skilled in the art can make without creative work and distortion still belong to the protection domain of this patent.
