Description

Anticorrosive energy-saving pump

The utility model relates to the structure of pump, a kind of specifically anticorrosive energy-saving pump.

The various working mediums of working power pump pumping in the industry, water, oil, gas body etc. for example, some pump work very easily corrodes at perishable environment such as acid, alkali, even corrosion also can take place and influence working life in the pump of pumps water, gas medium under long-term moist operation, the anti-corrosion capacity that improves pump is the direction of system pump industry always, in addition, the blade main shaft of general pump and motor branch are arranged, connect with coupling and to be one, not only mechanism is many, volume is big, and the external part of sharf needs good sealing, complex structure.

The purpose of this utility model provides a kind of anticorrosive energy-saving pump, has stronger anti-corrosion capacity, and simple in structure, and resistance is little, high working efficiency, economize on electricity

The purpose of this utility model is achieved in that

A kind of anticorrosive energy-saving pump is made up of the pump housing, blade and motor, and this motor has the stator that the iron-core coil of energising constitutes and cold rotor made from magnetic material, and its structure comprises

A. blade and rotor are contained on the same main shaft, and main shaft is supported by the bearing on the pump housing;

B. have through hole to be communicated with reflow pipe in the appropriate location of pump housing outlet, the end in addition of this reflow pipe has inlet to be communicated with the inner chamber that rotor is housed, and this inner chamber communicates with the inner room of dress blade;

C. the inner chamber wall of cartridge rotor and rotor outer wall all are coated with the corrosion-resistant material layer.

The utility model has following actively useful effect:

1, uses the blade of the stator that constitutes by the hot-wire coil iron core and motor of forming with cold rotor that magnetic material is made and pump combined, improved the working efficiency of pump.

2, the outer wall of the inner chamber wall of cartridge rotor and rotor all is coated with the corrosion-resistant material layer, stainless steel lining for example, and plastics anticorrosive coat, acid-and base-resisting coating layer, humidity corrosion layer etc., thus solved the corrosion-resistant problem of pump.

3, be provided with the looping construct of reflow pipe, motor is well cooled off, guaranteed the works fine condition of motor, prolong its working life part pumped medium introducing rotor internal cavity.

4, the structure that is communicated with rotor internal cavity of blade inner room has been cancelled the seal arrangement of sharf in original technology, and not only simplified structure has also reduced frictional resistance

5, blade and rotor are contained on the same main shaft, have cancelled the connection set between the sharf and motor shaft in original technology, not only make designs simplification, and it is long-pending also to have reduced full body.

6 compare with the prior art of pump split with motor, and this body is long-pending less, and weight is lighter, and manufacture cost is lower.

Now in conjunction with the accompanying drawings with preferred embodiment:

Fig. 1 is the utility model structural representation

Anticorrosive energy-saving pump of the present utility model is made up of the pump housing 1, blade 2 and motor, and this motor has the stator 3 that is made of the iron-core coil of switching on and cold rotor 4 made from magnetic material, and its structure comprises

Blade 2 is contained on the same main shaft 5 with rotor 4, and main shaft is by 6,7 supportings of the bearing on the pump housing;

Appropriate location in pump housing outlet has through hole to be communicated with reflow pipe 8, the end in addition of this reflow pipe has inlet to be communicated with the inner chamber 9 that rotor is housed, this inner chamber communicates with the inner room 10 of dress blade, thereby forms the MEDIA FLOW circulation in inner chamber 9, reaches the effect of cooling stator and rotor.

The wall of the inner chamber 9 of cartridge rotor and the outer wall of rotor 4 all are coated with corrosion-resistant material layer 11, shell, cover that this etch resistant material layer generally can use stainless steel to make, also can use acidproof, alkaline-resisting coating or coating to strong acid, highly basic medium, also can use moisture resistance wet antirust, the corrosion-resistant non-metallic material bed of material the aqueous vapor medium.

Claims (1)

1. an anticorrosive energy-saving pump is made up of the pump housing, blade and motor, and this motor has stator that the iron-core coil of energising constitutes and with cold rotor that magnetic material is made, it is characterized in that:

A. blade and rotor are contained on the same main shaft, and main shaft is supported by the bearing on the pump housing;

B. have through hole to be communicated with reflow pipe in the appropriate location of pump housing outlet, the end in addition of this reflow pipe has inlet to be communicated with the inner chamber that rotor is housed, and this inner chamber communicates with the inner room of dress blade;
