Abstract
The invention discloses a centrifugal pump and relates to the field of mechanical equipment. The centrifugal pump comprises a pump body, an impeller, a motor and a water inlet; the motor comprises a rotating shaft and a rotor; the impeller is fixedly connected to the rotating shaft; the motor is arranged in the pump body; and the water inlet is arranged at the bottom of the pump body. The centrifugal pump is characterized in that the rotor comprises a first coil and a second coil; the surface of the pump body is provided with a selective switch; a direct current gear and an alternating current gear are arranged on the selective switch; and the first coil and the second coil are connected with the direct current gear and the alternating current gear respectively. The motor adopts a direct current driving manner and an alternating current driving manner, and the corresponding motor driving manner is used according to concrete situations, so that the use range of the centrifugal pump is greatly increased, and the centrifugal pump has use flexibility and very high practical value.
Description
Technical field
The present invention relates to technical field of mechanical equipment, be specifically related to a kind of centrifugal pump.
Background technique
At ancient Chinese, from waterwheel, people solve a difficult problem for irrigation, and working as modern society, science and technology develops rapidly, and for people bring out and out benefit, the invention of centrifugal pump, makes people conveniently from underground water intake, very practical.Application number is application number: a kind of centrifugal pump of the disclosure of the invention of 201220568728.0, it includes rotatingshaft, impeller and pump main body, this centrifugal pump also includes locking element, and described locking element is arranged in pump main body, and is fixed on the rotating shaft by described impeller.Although this centrifugal pump has structure optimization, closure size is less, cost reduces and the advantages such as easy accessibility, but this centrifugal pump still has some shortcomings part, this water pump can only use a kind of power supply mode, or direct current supply, or Alternating Current Power Supply, not there is the flexibility of use, therefore can not use under multiple occasion again.
Summary of the invention
The object of the present invention is to provide a kind of centrifugal pump, to solve the above-mentioned multinomial defect caused in prior art.
A kind of centrifugal pump, comprise the pump housing, impeller, motor and water intake, described motor comprises rotating shaft and rotor, described impeller is fixed in rotating shaft, and described motor is located within the pump housing, and described water intake is located at the bottom of the pump housing, described rotor comprises the first coil and the second coil, described pump housing surface is provided with selector switch, and described selector switch is provided with zero frequency span and exchanges shelves, and the joint of described first coil and the joint of the second coil are all connected to selector switch.
Preferably, described selector switch surface is connected with watertightness barrier.
Preferably, the top of the described pump housing is provided with handle.
Preferably, described impeller is circular, and diameter is 15-20cm.
Preferably, described selector switch is cylindrical.
The invention has the advantages that: when Alternating Current Power Supply or direct current supply, selector switch is got to respectively and exchanges shelves and zero frequency span, corresponding motor drive mode is used according to concrete situation, considerably increase the using scope of centrifugal pump, there is the flexibility of use, there is very high use value, meanwhile, use also very convenient, watertightness barrier can make selector switch isolated water, and prevent electric leakage, handle facilitates people and moves centrifugal pump, the diameter that impeller is suitable for makes centrifugal pump to work normally, and columniform selector switch has intuitive.
Accompanying drawing explanation

Wherein: 1-pump housing, 2-water intake, 3-handle, 4-impeller, 5-selector switch, 6-rotating shaft, 7-motor, 8-zero frequency span, 9-exchange shelves, 10-watertightness barrier, the 11-the first coil, the 12-the second coil.
Embodiment
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the present invention further.
As shown in Figure 1, a kind of centrifugal pump, comprise the pump housing 1, impeller 4, motor 7 and water intake 2, described motor 7 comprises rotating shaft 6 and rotor, described impeller 4 is fixed in rotating shaft 6, described motor 7 is located within the pump housing 1, described water intake 2 is located at the bottom of the pump housing 1, as Fig. 2, described rotor comprises the first coil 11 and the second coil 12, and the described pump housing 1 surface is provided with selector switch 5, as shown in Figure 3, described selector switch 5 is provided with zero frequency span 8 and exchanges shelves 9, and the joint of described first coil 11 and the joint of the second coil 12 are all connected to selector switch 5.
It should be noted that described selector switch 5 surface is connected with watertightness barrier 10, watertightness barrier 10 can make selector switch isolated water, and prevent electric leakage, described selector switch 5 is cylindrical, has intuitive.
In the present embodiment, the top of the described pump housing 1 is provided with handle 3, facilitates people and moves centrifugal pump, and the diameter of described circular impeller 4 is 15-20cm, meets the needs that centrifugal pump draws water.
Based on above-mentioned, when Alternating Current Power Supply or direct current supply, selector switch is got to respectively and exchanges shelves and zero frequency span, corresponding motor drive mode is used according to concrete situation, considerably increase the using scope of centrifugal pump, there is the flexibility of use, there is very high use value, meanwhile, use also very convenient.
As known by the technical knowledge, the present invention can be realized by other the embodiment not departing from its Spirit Essence or essential feature.Therefore, above-mentioned disclosed embodiment, with regard to each side, all just illustrates, is not only.Within the scope of the present invention all or be all included in the invention being equal to the change in scope of the present invention.
