The pump has very low maintenance cost and high utilization rate and can be widely applied to the operation under various submerged environments.

Description

A kind of submerged pump

Technical field:

The present invention relates to submerged pump, especially a kind of pump machine that can be used in pond, pond, the aquarium.

Background technique:

In the pond, the medium place in pond or aquarium carries out submersible pump water and usually need to adopt the pump machine, these pump machines adopt electric drive mostly, impeller is with the water suction.We know that pump assembly is a kind of special motor, so water can not enter in the shell of motor, usually water is to enter in the motor, if but were sealed with problem, then water motor just might leak after after a while, will reduce like this life-span of motor and increase the motor periodic maintenance.The pump machine need to carry out good sealing for anti-sealing enters in the housing, needs when using simultaneously often to safeguard.

Another problem, if water enters in the pump machine, the floating dust particle in the water will be deposited in the motor, causes motor can't continue to use.For these reasons, in order to reduce maintenance, to reduce cost, the inventor provides under a kind of more reliably liquid (mainly being under water) to use the pump machine.

Summary of the invention:

Technical problem to be solved by this invention just is to overcome the deficiency of present product, and a kind of simple in structure, submerged pump of implementing easily, can not form the dirt deposition is provided.

For solving the problems of the technologies described above, the present invention has adopted following technological scheme: this pump machine comprises main body, be installed in main body motor and the impeller by motor driving, wherein impeller is positioned at an impeller space of pump machine end, this end also is provided with water intake and water outlet, described motor adopts brshless DC motor, it is made of stator and the rotor that is positioned at stator, wherein is formed with a gap between stator and the rotor, and this gap is connected to place, impeller space by washing away pipeline.

Described main body comprises for the inner space that rotor is installed and for the space outerpace that stator is installed.

Described rotor is fixed in the rotating shaft, and impeller is fixed on the termination of rotating shaft, and rotating shaft is installed in the inner space by two bearings.

Described main body and end are two independently parts, wherein offer the water intake and the water outlet that are communicated with the impeller space on the end.

What the present invention adopted is brshless DC motor, and this motor has many advantages, can energy saving.In addition, stator and the rotor of motor split installation, and we have saved a lot of operating costs and production process without any need for having sealed like this.In addition, because the current that impeller produces will so just can wash away the dirt that is deposited on herein totally by washing away the gap between pipeline inflow rotor and the stator, make this zone can not form the dirt deposition.The dirts such as the floating dust particle in the liquid will be discharged from by water outlet.

Maintenance cost of the present invention is very low, and its utilization efficiency is high, can be widely used in environment operation under the various liquid.The present invention has used engineering plastics in the part that contacts with liquid, the PU cable, and titanium alloy structure spare to play preservative efficacy, can at seawater, be worked under the environment such as soda acid.

Fig. 1 is plan view of the present invention;

Fig. 2 is section of the present invention stereogram;

Fig. 3 is plan view of the present invention;

Fig. 4 be among Fig. 4 A-A to sectional view.

Embodiment:

The present invention is further illustrated below in conjunction with accompanying drawing:

See Fig. 1～4, the present invention be a kind of under water the pump machine of (or other liquid), for example be used for pond, aquarium, be used for drawing water or changing the water operation.

This pump machine 1 comprises that is used for main body 3 and the end 2 that parts are installed, and main body 3 inside are equipped with rotor 4 and the stator 5 that consists of pump machine 1 motor.

Main body 3 and end 2 are separate, and its inside is formed with respectively separately separate space.Be formed with impeller space 17 in its medial end portions 2.This impeller space 17 is used for the running of impeller 10.Be provided with water intake 11 and water outlet 12 on the end 2, current are entered by water intake 11, through behind the impeller 10, are discharged by water outlet 12.

The motor of this pump machine 1 is brshless DC motor, and it is made of stator 5 and the rotor 4 that is positioned at stator 5, wherein is formed with a gap 6 between stator 5 and the rotor 4, and this gap 6 is connected to 7 places, impeller space by washing away pipeline 17.Concrete structure is: main body 3 comprises the inner space 31 and the space outerpace 32 that is used for installing stator 5 that are used for installing rotor 4.Be formed with gap 6 between the space outerpace 32 that is used for the installation stator and rotor 4, current can be flowed through by this gap 6.

Described rotor 4 is fixed in the rotating shaft 9, and impeller 10 is fixed on the termination of rotating shaft 9, and rotating shaft 9 is installed in the inner space 31 by two bearings 13,14.

At the inner space of main body 3 31 interior installation rotors 4, rotor 4 places are watertight, and water can't enter in the space outerpace 32, but the material such as filling epoxy resins in the space outerpace 32 especially to realize complete closed, makes water can't touch stator 5.

Rotor 4 comprises one or more magnet 15, and these magnet 15 adopt permanent magnet.

Rotor 4 and the gap 6 between the stator 5 at motor look like a pipe.Washing away pipeline 17 will be communicated with this gap 6.Flush pipe 17 is stand-alone products in this product.

The port one 6 of inner space 31 forms a flow body with the port one that washes away pipeline 17 8, and after impeller 10 rotates, along with impeller space 7 internal pressures increase, the part current will enter and wash away pipeline 17, enter gap 6, form flow.Therefore, all dirt particles will be washed away, and are washed into the outside by gap 6,

Above-mentioned is preferred embodiment of the present invention, and the present invention can be used in various place, for example: in pond, pond or the aquarium.The present invention is in order to prevent rotor 4 corrosion, and it can adopt some other corrosion-resistant materials such as titanium mesh.All used engineering plastics in the part that contacts with liquid, the PU cable, titanium alloy structure spare to play preservative efficacy, makes the present invention at seawater, work under the environment such as soda acid.

Certainly, the above only is example of the present invention, is not to limit the scope of the present invention, and all equivalences of doing according to the described structure of the present patent application claim, feature and principle change or modify, and all should be included in the present patent application claim.
