Connection；2nd, using the outer water jacket of thin-walled, shackle member is convexed to form on the madial wall of outer water jacket, and be provided with the end of pump portion
Bolt, bolt are provided with clamping block.
The first above-mentioned fixed form, although meeting the stability of submersible pump fixation to a certain extent, still
The fact that in the presence of submersible pump light-weight design can not be realized, therefore cause the installation of whole submersible pump and movement not square
Just；Above-mentioned second of fixed form, although realizing the quick fixation to submersible pump, the lightweight for realizing submersible pump is set
Meter, but submersible pump can produce larger impulse force during use, only using interface arrangment, submersible pump
Connect it is unstable, cause submersible pump using when potential safety hazard be present.
The content of the invention
The purpose of the present invention is above mentioned problem be present for existing technology, it is proposed that a kind of submersible pump, institute of the present invention
Technical problems to be solved are how to realize the stability to improving submersible pump installation in submersible pump light-weight design.
The purpose of the present invention can be realized by following technical proposal：
A kind of submersible pump, including outer water jacket and water inlet guard, the outer water jacket is interior to be provided with electric pump component, and its feature exists
In this submersible pump also includes mounting ring and some nuts, and the mounting ring is set in on water guard, and one end of mounting ring
It is resisted against on water guard, the other end has flange, and several fixing holes, the side wall of the outer water jacket are offered on the flange
On offer and pass through corresponding mounting hole to stretch into outer water jacket with the one-to-one mounting hole of nut, the side of the nut, institute
The edge that flange is resisted against outer water jacket is stated, and is connected by bolt through fixing hole with nut thread and water inlet guard is pressed on electricity
In pump group part.
Operation principle：First electric pump component is arranged in outer water jacket, then water inlet guard is embedded in outer water jacket and made into water
Guard is leant with electric pump component, and mounting ring is set in on water guard, and one end of mounting ring is with guard of intaking against by spiral shell
Bolt is connected through fixing hole with nut thread, and water inlet guard and mounting ring are pressed on electric pump component, because flange supports
The edge of outer water jacket is leaned against, now flange is also pressed on outer water jacket, is constantly tightened in bolt, and bolt produces one to nut
Individual pulling force, the pulling force make inwardly to be pressed on electric pump component into water guard, pulling force and thrust it is in opposite direction, can realize mutually
Locking, eliminates the installation gap between bolts and nuts, said structure employs relatively simple structure, only in Wai Shui
Put and offer mounting hole, and the setting for passing through nuts and bolt can be achieved with the installation to water inlet guard and mounting ring, therefore
The wall thickness of external water jacket is less demanding, passes through the mating reaction of nuts and bolt so that the installation of whole submersible pump is more
It is firm, so as to realize the stability to improving submersible pump installation in submersible pump light-weight design.
