Background technique:
Compressor pump is to use the most general a kind of universal machine in the present mechanical industry.Multiple structural types such as that compressor pump commonly used includes is reciprocating type, rotary, eddy type, wherein, again with reciprocating type most widely used.The driving of traditional reciprocating type compressor pump all is to use electric rotating machine, and will be rotatablely moved by electric rotating machine converts it into straight line motion by a cover mechanical system.This conversion process not only will consume part energy, has also increased the manufacture cost of compressor pump simultaneously.
In recent years, come the technology of drive compression pump day by day ripe, and brought into play its high efficiency, flexible, the advantages of simple structure and simple of control by linear electric motor.Particularly Japan and Korea S. and some American-European countries all successfully are applied to industrial production with it, and China still is in the starting stage, does not still have the precedent of application at present.Yet, make a general survey of the external at present straight line compressor pump of producing, and the relevant patent of being applied for, usually yet all adopt the compression structure of single-cylinder or single piston, the compressor pump of this single piston can only be realized unidirectional compression, thereby it has not only lost a work done action, and since compression process in air-breathing be different with the mechanical characteristic of compression process, and the power that the bidirectional-movement of linear electric motor is exported is balance, therefore, in the course of time, very easily cause the damage of linear electric motor component, and directly have influence on the working life of linear electric motor compressor pump.
Summary of the invention:
In view of the problem of above-mentioned existence, the purpose of this invention is to provide a kind of novel, rational in infrastructure, compact, the linear motor double cylinder compression pump of high working efficiency, long service life.
For achieving the above object, the present invention has taked following technological scheme:
Linear motor double cylinder compression pump of the present invention is to be provided with novel double-stator direct line motor and the double-cylinder structure that matches with it in compressor pump.Linear electric motor adopt moving-magnetic type linear motor, and are made up of stator, winding coil, piston; The stator quantity of double-stator direct line motor adopts 2 integral multiple.Piston is provided with silicon steel plate, is embedded with a permanent magnetic steel between each silicon steel plate.When coil of stator of motor passes to Ac, produce an oscillating magnetic field at motor stator, promote permanent magnetic steel and piston reciprocating vibration and do relative motion, thereby realize its compression function.
Through the linear motor double cylinder compression pump after the above-mentioned design, rational in infrastructure, compact, volume is little, high working efficiency, long service life, it not only can be used as the compressor of chiller plants such as air-conditioning, refrigerator, and can be widely used in every field such as pump apparatus and chemical industry, pharmacy, space flight, aviation.
