Abstract
The utility model discloses a peripheral pump with a built-in motor. The peripheral pump with the built-in motor is characterized by comprising a shell, wherein the shell is provided with a front cavity and a back cavity which are communicated; the shell is provided with a liquid inlet which is communicated with the front cavity; a peripheral pump impeller is arranged in the front cavity; the shell is provided with a liquid outlet which is communicated with the back cavity; and a rotor and a stator are arranged in the back cavity, and the rotor is connected with the peripheral pump impeller through a motor shaft. According to the peripheral pump with the built-in motor, the motor shaft is connected with the impeller through a coupling. Therefore, the shell of the pump is directly connected with a motor shell. A sealing device at the position of a bearing is eliminated, so that the risk of the leakage of conveyed liquid is reduced. Moreover, the risk of the leakage cannot be increased due to wear in the using process. The liquid flow passes through the surfaces of the stator and the rotor, so the heat generated by a motor is taken away. The motor cannot be in an overheated state.
Description
Technical field
The utility model relates to a kind of electric motor built-in peripheral pump.
Background technique
Peripheral pump of the prior art leans on motor driving work.Impeller is connected with motor output shaft through coupling.Impeller is arranged in the pump housing.Bearing bore is made up of bearing, rotary seal.The extension of impeller shaft passes bearing bore and gets in touch through coupling and motor.Motor is arranged in the electric machine casing.Three housings connect successively.When needs were carried corrosive liquids, the external contacting point of the pump housing and bearing cavity must seal.The sealing difference will cause leak of liquid, both can influence operator ' s health, also pollutes the environment.Because lean on the rotation of motor output shaft rotation impeller, impeller shaft is in the bearing bore housing, to rotate.Be provided with rotating seal ring in the bearing bore housing, seal ring is enclosed within on the axle.Seal ring both need seal the position that each possibly revealed, and need touch with supporting shaft with being coupling again.Transmission shaft spin friction seal arrangement causes seal arrangement wearing and tearing back to occur revealing.Along with the prolongation of service time, the wearing and tearing of seal ring will constantly increase the weight of and seriously reduce sealability and directly cause and can generation leak.
The model utility content
The purpose of the utility model is in order to overcome deficiency of the prior art, and a kind of electric motor built-in peripheral pump of leaking of can not causing is provided.
For realizing above purpose, the utility model is realized through following technological scheme:
The electric motor built-in peripheral pump is characterized in that, comprises housing, and housing is provided with ante-chamber and back cavity, and ante-chamber is communicated with back cavity; Housing is provided with liquid entering hole, and liquid entering hole is communicated with ante-chamber; Be provided with the peripheral pump impeller in the ante-chamber; Housing is provided with liquid outlet, and liquid outlet is communicated with back cavity; Be provided with rotor and stator in the back cavity, rotor is connected through motor shaft with the peripheral pump impeller.
Preferably, said housing comprises electric machine casing and pump case; Pump case is provided with ante-chamber; Pump case is provided with liquid entering hole; The back cavity two ends are provided with protecgulum and bonnet; Electric machine casing is provided with protecgulum and bonnet; Pump case is connected on the protecgulum; Liquid outlet is arranged on the bonnet.
Electric motor built-in peripheral pump in the utility model, motor shaft is connected through coupling with impeller.Therefore, pump case directly is connected with electric machine casing.The utility model has omitted the seal arrangement at bearing place, has reduced the danger of carrying leak of liquid.And in the using process, can not increase the danger of leakage because of wearing and tearing.And.Because flow is through stator and rotor surface, thereby the heat that motor produced is taken away.Motor can not produce superheat state.
Description of drawings
Fig. 1 is the utility model structural representation.
Embodiment
Below in conjunction with accompanying drawing the utility model is carried out detailed description:
As shown in Figure 1, the electric motor built-in peripheral pump comprises housing 1, and housing 1 comprises electric machine casing 2 and pump case 3.Pump case 3 is provided with ante-chamber 4.Pump case 3 is provided with liquid entering hole 5.Liquid entering hole 5 is communicated with ante-chamber 4.Be provided with peripheral pump impeller 6 in the ante-chamber 4.
Electric machine casing 2 is provided with back cavity 7.Back cavity 7 two ends are provided with protecgulum 8 and bonnet 9.Bonnet 9 is provided with liquid outlet 10.Liquid outlet 10 is communicated with back cavity 7.Be provided with stator 11 and rotor 12 in the back cavity 7.
Pump case 3 is connected on the protecgulum 8.Motor shaft 13 passes protecgulum 8, and two ends are connected with peripheral pump impeller 6 with rotor 12 respectively.
Each component of the utility model adopt the resistant material manufacturing.
During use, the energising starting electrical machinery, rotor 12 rotations drive 6 rotations of peripheral pump impeller through motor shaft 13.6 rotations of peripheral pump impeller can suck liquid in the ante-chamber 4 from liquid entering hole 5, and under the effect of peripheral pump impeller 6, input in the back cavity 7 and discharge through liquid outlet 10, are delivered to the place to use.The glide path of liquid is shown in the arrow among the figure.The utility model can reduce the risk of leakage, especially is fit to carry corrosive liquids, can be used in and carry the used refrigerant material of chiller plant.
Embodiment in the utility model only is used for the utility model is described, and does not constitute the restriction to the claim scope, and other substituting of being equal in fact that those skilled in that art can expect are all in the utility model protection domain.
