The transmission structure is characterized by also comprising a transition sleeve for connecting the impeller and the main shaft to transmit torsion. Barriers to the manufacture of an abrasion resisting pump from a glass ceramic material are eliminated, the glass ceramic material is widely applied to the field of abrasion resisting pumps, and the service life of the conventional abrasion resisting pump in China is greatly prolonged.
Description
Technical field
The utility model relates to a kind of centrifugal pump impeller drive mechanism, relates in particular to the impeller transmission structure that a kind of impeller material is sytull.
Background technique
The utility model is the improvement to centrifugal pump sytull impeller, relates in particular to the improvement that impeller is connected with main shaft.Sytull is a kind of extremely wear-resisting material, when being used as the impeller transfer ore pulp of centrifugal pump, its wear-resisting property is the twice of high-chromium alloy, more than 6 times of ultra-high molecular weight polyethylene, and the impeller of this material also has good antiseptic property and heat resistance, 150 ℃ of uses with interior acid valency matter, not only anticorrosion but also wear-resisting, be specially adapted to non-ferrous metal hydrometallurgy and mine ore dressing industry.
Though the wear resistance of sytull is good, fragility is large, hardness is high, is difficult to machining.Especially impeller is a difficult problem with the cooperation of main shaft with being connected always: the one, and coupling is connected with keyway with key, because of microcrystal glass material fragility large, keyway in the impeller bore easily rolls key, produce and damage, especially diameter is greater than the impeller more than the 200mm, and because impeller diameter is large, the impeller distortion power is large, used 2 ~ 3 days, and namely rolled key and just damaged.This problem can not get solving for a long time, and the sytull impeller was used for centrifugal pump existing nearly 10 years, but because many reasons is never effectively promoted, wherein to roll key also be a major reason to impeller.Therefore seem very little technical problem, but to the application of sytull impeller, play conclusive inhibition, have much room for improvement.
Summary of the invention
The utility model is for the deficiencies in the prior art, provides that a kind of twisting resistance is strong, non-damageable sytull centrifugal pump impeller drive mechanism.
The utility model is for solving the problems of the technologies described above, provide following technological scheme: a kind of sytull centrifugal pump impeller drive mechanism, comprise impeller, main shaft, offer center hole on the impeller, characterized by further comprising one is used for impeller is connected the spacer shell that transmits torsion with main shaft, described spacer shell outer surface is provided with lug boss and/or depressed part, and the impeller center hole arranges corresponding depressed part and/or lug boss.
Preferred described lug boss is the some bar shaped projections that are axially set in the spacer shell outer surface, and impeller center hole correspondence is provided with some strip groove couplings and connects.
Preferred described lug boss is some bar shaped projections and the groove that is axially set in the spacer shell outer surface, and impeller center hole correspondence is provided with some strip grooves, and coupling is connected with projection.
Preferred described lug boss is the ladder-type boss that is arranged at the spacer shell outer surface, and impeller center hole correspondence is provided with the stepped groove coupling and connects.
Have additional projection radially on the preferred ladder-type boss, be provided with corresponding groove in the described stepped groove, both couplings connect.
Preferred described spacer shell outer surface, impeller center hole respectively are provided with corresponding groove vertically, and groove fastens mutually, is inlaid with elastic materials in the groove.Use this kind setting, when combination is installed, between two grooves, embed elastomer, both reached the effect of transmitting torsion, also play the function of antidetonation.
The preferred elastomeric material body is polyurethane strip or piece.
Further improve as the utility model, spacer shell is coated with the plastic anti-corrosion layer, and preferred plastic anti-corrosion layer is plastic pellicle.
The purpose of this utility model realizes being, between impeller and main shaft, set up the spacer shell of a transmission main shaft torsion, the point of attachment that spacer shell cooperates with main shaft, can offer keyway, install by key and main shaft coupling, the spacer shell outer surface is provided with lug boss and/or depressed part, corresponding depressed part is set the impeller center hole and/or the lug boss coupling connects, when with the spacer shell coupling spindle operation being installed, torsion is passed on the impeller by spacer shell, impeller is produced rotatablely move, prevented that the torsion to axle is directly delivered on the sytull impeller in original technology, make the keyway concentration of local of impeller stressed, make the keyway kibe, and then damage impeller, the utility model passes through the torsion on the main shaft, by the effect of spacer shell, be dispersed to a plurality of concavo-convex coupling section of impeller, by an original force bearing point, be dispersed into a plurality of force bearing points, make each force bearing point only partly bear the torsion of main shaft, reduced the possibility of impeller force bearing point kibe, the sytull impeller can be run well.
The beneficial effects of the utility model: 1. overcome original technology sytull impeller and can roll key, an easy cracked difficult problem can increase substantially working life of impeller.
2. made things convenient for dismounting, during original technology dismounting, impeller is deviate from comparatively difficulty from main shaft, and slightly careless, impeller will ftracture, and the technology after the improvement is only required the fixing cap of piecing together of impeller, and impeller just can unload very easily.3. improve the yield rate that the sytull impeller is produced, and saved cost of production.The position that the impeller center cooperates with main shaft in original technology, for satisfying the needs of twisting strength, can only be designed to convexity and thicken shape, when this structure causes making sytull impeller base substrate, crystallization is very difficult, yield rate is low, technology after the improvement in protuberance change the concave structure into, making and crystallization that this has just made things convenient for impeller have improved the yield rate of manufacturing efficiency and product.4. can increase substantially the working life of domestic wear pump, the sytull pump is existing people's trial-production before 20 years, and successful case is not yet arranged so far, and one of its major reason is exactly impeller cracking well damage and manufacturing difficulty.After the utility model overcomes above-mentioned deficiency, just get rid of the sytull material and be used for the obstacle that wear pump is made, sytull is used widely in the wear pump field, significantly promoted the working life of domestic existing wear pump.
