Description
Technical field
The utility model belongs to plant maintenance maintenance technical field of auxiliary equipment, and in particular to a kind of long shaft pump impeller dismounting
Device.
Background technology
In mineral processing circuit, long-shaft pump is mainly used in the conveying of ore pulp, and in the course of work, long-shaft pump is based on centrifugal force
By pulp conveying to target area under effect.The groundwork position of long-shaft pump is impeller, and impeller belongs to running stores, due to corruption
The reasons such as erosion, abrasion, cavitation erosion, generally require the time of six months or so, and the service behaviour of impeller does not just reach production and application
It is required that in ore dressing effect, the installation clinker of long-shaft pump is more, and, it is necessary to regularly replace the impeller of damage, maintenance load is larger,
Long shaft pump impeller circular conical surface cooperation be present with axle and keyway plane coordinates, and causes difficult, the traditional method for dismounting master of impeller demolition
To be that manpower beats impeller surrounding by hand, progressively impeller is released from rotary shaft, impeller demolition is got off, beats strength sometimes
It is uneven, easily cause during stress unbalance loading impeller to coordinate surface damage with pump shaft, dismounting relies primarily on the dismounting experience of worker, maintenance
Replacing difficulty is big, and operating efficiency is low, and the labor intensity of worker is big.
Utility model content
The purpose of this utility model is to provide a kind of long shaft pump impeller provision for disengagement, is difficult to solving impeller in the prior art
Dismounting, dismounting rely on worker's working experience, and the problem of difficulty is big, and operating efficiency is low, and labor strength is big is changed in maintenance.
To reach above-mentioned purpose, the technical solution of the utility model is：A kind of long shaft pump impeller provision for disengagement, including support
Plate 1, shaft holder 2 and ejection frame 3, supporting plate 1 are fixedly connected with motor 4, and the side of supporting plate 1 is connected with axle and fixed
Frame 2, jack 5 is connected between shaft holder 2 and ejection frame 3.
Preferably, the side of shaft holder 2 is fixedly connected with fixed seat 6, and shaft holder 2 is fixed by fixed seat 6 and axle 7
Connection.
Preferably, ejection frame 3 is hollow circular cylinder, and the both sides of ejection frame 3 are provided with fixed ear 8, and the bottom of fixed ear 8 is provided with
Ejector plate 9, ejection frame 3 are flexibly connected by fixed ear 8 with axle 7.
Preferably, the external diameter of ejection frame 3 is less than the internal diameter of the through hole 11 on pump cover 10, and more than the external diameter of axle 7.
The utility model has the advantage of：The utility model is simple in construction, can be quickly by major axis using machine power
The impeller demolition of pump gets off, and separates impeller and pump shaft, effectively reduces the damage probability of impeller and pump shaft mating surface, dismounting
Speed is fast, substantially increases operating efficiency, makes the dismounting summary of long shaft pump impeller, reduces maintenance cost, alleviate worker
Labor intensity.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the overlooking the structure diagram of shaft holder.
Fig. 3 is the overlooking the structure diagram of ejection frame.
Embodiment
The utility model is described in further detail with embodiment for explanation below in conjunction with the accompanying drawings.
A kind of long shaft pump impeller provision for disengagement as shown in Figure 1, Figure 2 and Figure 3, including supporting plate 1, shaft holder 2 and push away
Upper frame 3, supporting plate 1 are fixedly connected with motor 4, and the side of supporting plate 1 is connected with shaft holder 2, and shaft holder 2 is with pushing away
Jack 5 is connected between upper frame 3.
In order that shaft holder 2 is fixed more firm with axle 7, the side of shaft holder 2 is fixedly connected with fixed seat 6, axle
Fixed mount 2 is fixedly connected by fixed seat 6 with axle 7.
Pushing tow is carried out to impeller 12 in order to facilitate jack 5, facilitates the dismounting of impeller 12, setting ejection frame 3 is hollow circle
Cylinder, the both sides of ejection frame 3 are provided with fixed ear 8, and the bottom of fixed ear 8 is provided with ejector plate 9, and ejection frame 3 passes through fixed ear 8 and axle
7 are flexibly connected.
In order that ejection frame 3 coordinate with impeller 12 it is more preferable, set ejection frame 3 external diameter be less than pump cover 10 on through hole 11
Internal diameter, and more than axle 7 external diameter.
During work, shaft holder 2 is first mounted in the both sides of axle 7, shaft holder 2 is fixed by fixed seat 6, and will
One end of shaft holder 2 acts against the side of supporting plate 1, then by ejection frame 3 at the through hole 11 of pump cover 10, by it is fixed and
8 are fixed together ejection frame 3, after ejection frame 3 and the dieback of impeller 12, are installed between shaft holder 2 and ejection frame 3 very heavy
Top 5, by lifting jack 5, under the mechanism of jack 5, coordinate ejection frame 3 to disassemble impeller from axle 7, enter
Row is changed, and effectively reduces the damage probability of impeller and pump shaft mating surface, and dismounting speed is fast, substantially increases operating efficiency,
Maintenance cost is reduced, alleviates the labor intensity of worker.
Above-described is only preferred embodiments of the present utility model, and the technical solution of the utility model is not limited thereto,
It should be understood that to those skilled in the art, under technical inspiration provided by the utility model, as this area
Common knowledge, other equivalent modifications and improvement can also be made, also should be regarded as the scope of protection of the utility model.
