The utility model is an electromotor-pump, which sets an electromagnet as a stator in the waterproofing condition of the inside of the electromotor shell, and the magnetic force of the rotating magnetic field of the stator penetrates a permanent magnet rotor. A bearing supporting revolving drum arranged on the side plate and the helicoidal surface of the revolving drum form an integral part, and the helicoidal surface is arranged on the stationary shaft which is arranged on the support of the side plate, and the stator of the electromotor, the revolving drum and the helicoidal surface rotate and reciprocate together on the stationary shaft to transfer liquid. The utility model has the advantages of simple structure, convenience in utilization, and meanwhile does not need to be driven by other dynamic gearing device, and has wide practicality.

Description

Electric-motor pump

The utility model relates to electric-motor pump, specifically: helical rotor rotation pump structure is set in motor.

Existing all kinds of pump must motor or other power drive, as existing volute pump is to be driven by the power plant of motor by joiner to realize, its deficiency is: the single unit system complexity, all inconvenience of carrying, installation, use, and it is big to take up room, simultaneously, energy loss is big in the power transmission process.

The purpose of this utility model is, a kind of have motor and pump dual functions are provided, and makes both become the electric-motor pump of one.

Another purpose of the present utility model is, removes power transmission between motor and pump, and machinery is simplified, make easy, eliminate the energy loss problem in the power transmission link, provide the electric-motor pump of structure mini, to satisfy the widely used demand of all trades and professions.

The purpose of this utility model is realized by following technological scheme: a kind of electric-motor pump, in motor casing, the electromagnet that is provided with under the condition of waterproof is a stator, get rid of the electric leakage problem, it is rotor that permanent magnet is set in stator rotating magnetic field cylinder, rotor rotates in cylinder, the bearing that is loaded on the side plate supports non magnetic rotating cylinder, in the rotating cylinder is pump chamber, negative helicoid is set in the rotating cylinder forms the helical rotor of rotary pump, helical rotor places on the stationary axle, and stationary axle is loaded in the supporting of left and right side plate 5.

Electric-motor pump of the present utility model is that the electromagnet in the motor casing is connect ac power supply, produces alternating magnetic field, change in polarity along with magnetic force, make the rotor rotation of permanent magnet, make the helicoid change in location of the helical rotor that is loaded on the stationary axle, liquid sucting port sucks liquid toward the liquid port reciprocal transportation.

The utility model has the advantages that: owing to have the function of pump in the rotor, therefore, motor and pump become one structure.Make simple in structurely, can be made into the micromachine pump, to satisfy the widely used demand of all trades and professions: there is not the power transmission mode between motor and the pump, eliminated the energy loss problem in the power transmission link, thereby improved the utilization ratio of power, simultaneously, also eliminated powerdriven noise.

The utility model illustrates the motor volute pump, but does not limit to this pump, and the mode of various rotation pumps is all relevant with the present technique scope in every rotor.

Formation of the present utility model:

Fig. 1 is the cross-section generalized section of the utility model motor volute pump.

Fig. 2 is the vertical section schematic representation of Fig. 1.

Significant points symbol description among the figure:

1 motor, 2 shells, 2a, 2b side plate, 3 stators, 4 rotors, 4a rotating cylinder, 4d pump chamber, 4s helicoid, 6 stationary axle.

With reference to Fig. 1-2, the shell 2 inherent anti-water conditions of motor 1 are divided into and put electromagnetic core 3a is stator 3, and the magnetic force of stator 3 rotating magnetic fields penetrates the revolution range of rotor.Rotor 4 is cylindric permanent magnets, and the space that forms in the rotor 4 is provided with rotating cylinder 4a, is pump chamber 4d in the rotating cylinder 4a, and rotating cylinder 4a two ends are fixed on the block bearing 5 of left and right side plate 2a, 2b.Rotating cylinder 4a becomes one by adhesives layer 4c and rotor 4.In pump chamber 4d, negative helical rotor is set and rotating cylinder 4a inner peripheral surface is into a single integrated structure.The rotating center of helicoid 4s is loaded on the stationary axle 6, and the both ends horizontal of stationary axle 6 is provided with liquid sucting port 2n and liquid port 2u, has in the center portion supporting 2r is set on side plate 2a, the 2b of water port 2w, and supporting 2r is a cushion rubber.Helicoid 4s is rotated around stationary axle 6, helicoid 4s make liquid in the pump chamber 4a from the liquid sucting port liquid port to reciprocal transportation.

When electric-motor pump of the present utility model is worked, motor 1 is connected power supply, make the electromagnetic core 3a of stator 3 produce rotating magnetic field, this magnetic field is to the permanent magnet effect of rotor, make the change in polarity of rotating magnetic field, rotor 4 is rotated by the clock direction, the rotating cylinder 4a of block bearing 5 supportings is rotated with the ac frequency corresponding rotating speeds.Helicoid 4s is along with rotor 4, rotating cylinder 4a rotate around stationary axle 6 together, and stationary axle 6 is in quiet system, and the helicoid 4s of rotation becomes moving system, moves when being a direction variation, and liquid is discharged from liquid port then by the pump chamber 4d that liquid sucting port 2n sucks rotating cylinder 4a.At this moment, liquid flows to liquid port 2u from liquid sucting port 2n laminar flow, and therefore, no liquid is impacted the energy loss that causes, and has improved reciprocal transportation efficient.Magnetic force by the stator rotating magnetic field makes its rotor rotation directly act on the helicoid rotation, has solved the energy loss problem in the power mode of movement, has improved the mechanical efficiency of pump.

Effect of the present utility model:

The utility model is the mode that has pump in the rotor, therefore, motor and pump is become one, its Simple in structure, can make the micro electric pump, simultaneously, of many uses. Owing between motor and pump, remove Actuating unit, the energy loss that can avoid the power transmission link to cause has improved the power profit of pump Use rate. Because motor and pump became one, and the space that arranges of motor, pump is reduced relatively, compact conformation, Volume is little, and is in light weight, compares with existing helicoidal pump, has a significant effect in the use.
