Description
Technical field
The utility model is related to axial-flow pump technical field, more particularly to a kind of large power shaft stream pump packing structure part.
Background technology
Axial-flow pump is thrust (lift) work produced to water body using impeller rotation, is a kind of water of big flow low lift
Pump.The motor and water pump of axial-flow pump are the structures being directly integrated in production, therefore need not carry out work consuming, consumption in erecting bed
When motor, transmission mechanism, the assembly process of water pump axis centering, in-site installation is convenient, quickly.
Because motor is just integrally formed with water pump in production, because the sealing for structure just has in use
Certain requirement, if poor sealing will influence the normal work of motor, can also damage motor when serious.Particularly big
In power axial-flow pump, because axial-flow pump power ratio is larger, in use for some time motor component often because sealing not
Motor damage is caused well, influence is normally used.
Utility model content
The purpose of this utility model is to provide a kind of large power shaft stream pump packing structure part, solves axial-flow pump sealing not
Good technical problem, strong guarantee is served to the sealing of high-power axial-flow pump.
The technical solution of the utility model is as follows：
A kind of large power shaft stream pump packing structure part, it is characterised in that：Including assembling base, the assembling base lower end sets
There are mounted inside axle, the diameter of the diameter less than the assembling base of the mounted inside axle, the assembling base center
Circular groove is provided with, the groove center position is provided with main assembled shaft, is provided between the main assembled shaft and the assembling base
Three equally distributed reinforcements, the main assembled shaft top is provided with central shaft, between the central shaft and the main assembled shaft
The second seal groove is provided with, the central shaft is hollow structure, and the mounted inside axle is provided with the first seal groove, the internal dress
With reverse taper hole is additionally provided with axle, the diameter of first seal groove is less than the diameter of the mounted inside axle, and described second is close
Diameter of the diameter of sealing groove less than the central shaft.
Further, diameter of the diameter of the central shaft less than the main assembled shaft；The diameter of the main assembled shaft is small
In the diameter of the mounted inside axle.
Further, the assembling base is provided with three fixing holes, and the main assembled shaft is provided with a location hole.
The beneficial effects of the utility model：
The utility model solves requirement of the high-power axial-flow pump to sealing by setting two groups of seal groove structures, protects
Hinder the safe operation of high-power axial-flow pump, increase its service life.

Specific embodiment
As shown in Figures 1 to 4, a kind of large power shaft stream pump packing structure part, can provide one to high-power axial-flow pump
Safer sealing guarantee, it is ensured that the safety of axial-flow pump work is carried out.It is the weight of seal structural part including assembling base 1
One of part is wanted, it is the agent structure of whole seal structural part.Assembling base 1 lower end is provided with mounted inside axle 4,
Mounted inside axle 4 is directly attached with motor, so as to provide operation power to whole axial-flow pump by motor.The inside
The diameter of assembled shaft 4 can also make the fixation of seal structural part strong less than the diameter of the assembling base 1 with cost-effective
Degree reaches expected requirement.Assembling base 1 center is provided with circular groove, and sealing is mitigated while cost is reduced
The overall weight of structural member.The groove center position is provided with main assembled shaft 2, uses cooperatively to reach with other drive mechanism parts
The need of work of axial-flow pump.Three equally distributed reinforcements 5 are provided between the main assembled shaft 2 and the assembling base 1,
Ensure that the intensity of seal structural part is unaffected while mitigating whole weight, it is ensured that the security and service life of part.
The top of the main assembled shaft 2 is provided with central shaft 3, and central shaft 3 is for carrying out accurate assembly with fit structure part, it is ensured that part
Installation site is correct.The second seal groove 7 is provided between the central shaft 3 and the main assembled shaft 2, is put on the second seal groove 7
Sealing gasket is put to ensure sealing when pump body power is transmitted.The central shaft 3 is hollow structure, the mounted inside
Axle 4 is provided with the first seal groove 6, sealing gasket is placed on the first seal groove 6 to ensure the sealing of motor, it is ensured that motor is in work
The potential safety hazard of poor sealing is not had when making.Be additionally provided with reverse taper hole 10 on the mounted inside axle 4, for motor knot
Structure more closely coordinates, it is ensured that motor provides the efficiency of power.The diameter of first seal groove 6 is less than the mounted inside axle
4 diameter, such sealing gasket just can closely be placed on the first seal groove 6, it is played better seal and act on.Described
The diameter of two seal grooves 7 less than the central shaft 3 diameter, also for ensuring that sealing gasket can preferably play the close of it
Envelope is acted on, further the security to ensure overall service life and run.
Preferably, diameter of the diameter of the central shaft 3 less than the main assembled shaft 2；The diameter of the main assembled shaft 2
