Description
Technical field
The present invention relates to technical field of environment protection equipment, more specifically, being related to a kind of motor and its packaging technology.
Background technology
Motor refer to according to the law of electromagnetic induction realize electric energy conversion or transmit a kind of calutron, mainly by shell,
Stator module and rotor assembly are constituted, and type is various, while being also to be widely used, wherein also have motor in aerator.
Aerator is mainly made of immersible pump, ejector, air diffuser, air intake duct and five part of hose, its working principle is that：Water pump vane
Water push-in ejector is formed jet stream, further through the diffuser of ejector by jet stream by the high speed rotation under submersible motor drive
Kinetic energy enters air diffuser after being gradually transformed into pressure energy, is sufficiently mixed in the trunnion of ejector and into promoting the circulation of qi and water in air diffuser,
Meanwhile under the action of Jetstream fluid pressure, jet stream is sprayed from the nozzle of air diffuser, is spread, and is formed to water body and to biochemistry
After the impact of pond base sludge, stirring, the water surface is slowly risen to by bottom of pond, microbubble in water the residence time be generally up to 30 seconds with
On, so that the oxygen in air is fully dissolved and is absorbed, improves oxygen transfer efficiency and oxygenation capacity.
Its power source operated is that motor, is used because aerator is in underwater, then motor just needs good close
Feng Xing, in the prior art, the leakproofness to ensure motor are good, and the end cap at motor both ends is pressed into shell by the way of punching press
It is interior so that gap reduces between shell and end cap, but this mode assembles inconvenience, equally also results in the consequence that can not be dismantled,
Once motor internal damage, can only integral replacing, can not repair, cost is also unfavorable for greatly environmental protection.
Invention content
The first object of the present invention is to provide a kind of motor, and shell and end cap are detachably connected, convenient for assembling, to just
In later period maintenance, reduces cost and meet environmental requirement.
The present invention the first purpose of above-mentioned technology technical scheme is that：A kind of motor, including shell
Body and the end cap for being fixedly installed in shell both ends, the end cap include the inner cover being placed in shell and are connected with inner cover outer
Lid, the position limiting structure of the restricted inner cover disengaging shell of the interior setting of the shell, and the outer cover, which have, is connected to shell end face
First flanging.
By using above-mentioned technical proposal, end cap is divided into outer cover and inner cover, inner cover is fixed through the position limiting structure in shell
In shell, outer cover is limited through the first flanging outside shell, then by the connection of outer cover and inner cover, to which outer cover is fixed on shell
It on body, and then realizes that end cap is integrally attached to shell both ends, while outer cover and the double guarantee of inner cover is set, improve the sealing of motor
Property, outer cover avoids enclosure interior from intaking, and inner cover protects enclosure interior oil leak etc. so that motor is integrally easy to disassemble, later period maintenance
It is convenient, it reduces cost and meets environmental requirement.
The further setting of the present invention is, the position limiting structure includes connecting and fixing in the clamp spring in shell, and described
Inner cover has the second flanging abutted for clamp spring.
