Abstract
The utility model relates to a dynamic balancing test tool for a large water pump impeller with a diameter more than 2000 m. The dynamic balancing test tool has the structure as follows: the intermediate part of a mandrel is provided with a cone-shaped bench, the cone-shaped bench is arranged in the inner hole of a mandrel sleeve and is axially fixed by a key, and two ends of the mandrel sleeve are provided with axial locking devices. The structure has strong interchangeability and is suitable for dynamic and static balancing tests to large-scale impellers of different types and different specifications. Operation is simple, positioning is accurate, costs are reduced, the efficiency is raised, and the balance precision is guaranteed. Mounting and dismounting are convenient, the locking effect of the impeller and the mandrel is good, the impeller mandrel hole surface quality and size precision in the dynamic balancing test are not affected.
Description
Technical field
The utility model relates to a kind of water pump vane frock, especially relates to a kind of impeller diameter and surpasses the above large-scale water pump vane dynamic balance test tool of 2000mm.
Background technology
In the water pump vane manufacture process, impeller balance is an important indicator in the pump designing requirement, its precision height, and order of accuarcy directly affects running quality, and product serviceable life.Therefore in the pump design, the requirement of pair quality of balance is arranged.The dynamic and static balance of impeller is widely used in the industry departments such as oil, chemical industry, water power, nuclear power.
In prior art, when impeller dissimilar, different size is carried out to dynamic balance running, need select different equipment, not only increase cost, and complex operation, efficiency is lower.
Summary of the invention
The utility model is for above-mentioned problems of the prior art, a kind of water pump vane dynamic balance test tool is provided, solved different size in prior art, the dynamic and static balance test of the impeller of different types of structure need be selected the problem of distinct device, and the utility model is simple to operate, interchangeability is strong, balance quality is high.
The technical solution of the utility model is as follows:
The water pump vane dynamic balance test tool, the mandrel middle part is provided with the taper platform, and mandrel taper platform is assemblied in axle sleeve in hole, and radially fixing by key, and the two ends of axle sleeve arrange axial locking device.
In described axle sleeve, hole and mandrel taper platform adopt the 1:50 taper fit.
Described locking device is set nut and bolt.
Described mandrel two ends are provided with support set, and the below of support set arranges the strong point.
Described axle sleeve is assemblied in impeller shaft hole.
The protection packing ring is equipped with at described impeller two ends.
Be provided with round nut and holding screw locking between described impeller and axle sleeve.
Advantageous effect of the present invention is as follows:
1, from structure, very strong interchangeability is arranged, to the impeller of disalignment hole dimension, mandrel is general, be applicable to dissimilar, the different size macrophyll moves in turn, static balancing test.Simple to operate, as long as change the cast iron axle sleeve between impeller and mandrel, guarantee that the impeller shaft hole surface does not scratch before balance.
2, adopt the inner conical drogue cast iron axle sleeve of 1:50 from precision, guarantee quality of fit, accurate positioning.
3, save material from cost, reduce costs.When different size axis hole size impeller balance is tested, changed cast iron axle sleeve and set nut, only cast iron axle sleeve and set nut are designed.Other parts are not being designed.
4, adopt and change less part from quality control, produce the manufacture cumulative errors little, other uses part, when balance test first, to have reached the tension metrics requirement, raises the efficiency, and guarantees balance quality.
5, installation and removal are convenient, cost is low, and impeller and mandrel locking are effective, do not damage impeller shaft hole surface quality and dimensional accuracy in the dynamic balance running process.
The accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
In figure, 1, mandrel, 2, support set, 3, impeller, 4, key, 5, axle sleeve, 6, bolt, 7, set nut, 8, packing ring, 9, the strong point, 10, shaft coupling.
Embodiment
Referring to accompanying drawing, in conjunction with specific embodiments, describe the present invention in detail.
embodiment 1
As shown in Figure 1, mandrel 1 two ends are provided with quenching support set 2, and the below of support set 2 arranges the strong point 9; Mandrel 1 middle part is provided with the taper platform, and mandrel taper platform is assemblied in 5 li holes of axle sleeve, and radially fixing by key 4, and 5 li holes of axle sleeve and mandrel taper platform adopt the 1:50 taper fit, and set nut 7 is set at the two ends of axle sleeve 5 and bolt 6 carries out axial locking.Axle sleeve 5 is assemblied in impeller 3 axis holes, is provided with round nut and holding screw locking between impeller 3 and axle sleeve 5; Protection packing ring 8 is equipped with at the impeller two ends.
The course of work of the present utility model is as follows:
The first step: the 1:50 of place tapering platform keyway in the middle of mandrel, set level key.
Second step: the impeller shaft hole cast iron axle sleeve of packing into, the protection packing ring is put at the impeller two ends, with round nut and holding screw, impeller and cast iron axle sleeve is locked, and is connected firmly.
The 3rd step: then will assemble firmly impeller and cast iron axle sleeve and be contained on mandrel, and coordinate with 1:50 tapering platform.
The 4th step: mandrel two end supports point is placed on the equilibrator carrier roller frame.
The 5th step: mandrel one end is connected with equilibrator with shaft coupling, and driving torque carries out balance test.
The utility model is particularly useful for impeller diameter and surpasses the above large-scale water pump vane of 2000mm; but also applicable for small impeller by adjusted size; the above is specific embodiment of the utility model and the know-why used; any equivalent transformation based on the technical solutions of the utility model basis, within all belonging to protection domain of the present utility model.
