The utility model purpose is realized by following technical scheme: the two compacting of this double frequency cryogen reclaims machine, Pressure gauge is installed, control valve on frame; overload protective device; pressure switch, oilless (oil free) compressor, motor; blower fan; condenser, shell is characterized in that the drive motors of oilless (oil free) compressor adopts the two piezoelectricity machines of double frequency; motor connects change-over switch, and overload protective device wherein, pressure switch are selected for use and supported the two classifications of pressing of double frequency.
From the cold-producing medium of air-conditioning or other refrigeration systems, enter control valve after the process filter filters, and then enter the cylinder of oilless (oil free) compressor.The cold-producing medium of low-temp low-pressure becomes the gas of HTHP after overcompression, enter the liquid that condenser condenses becomes low-temp low-pressure then.Delivery outlet through control valve is discharged in the refrigerant-recovery jar at last.Thereby the recovery and the purification of cold-producing medium have been realized.
Use a cover auxiliary winding and two cover main windings in the motor, one cover auxiliary winding is as public starting winding, when change-over switch is got to the right, be " 220 " shelves of change-over switch, E in the change-over switch, F and A, B connect respectively, two cover 110V main windings are cascaded, and the main winding of this moment equals the winding of a cover 220V, so make motor to work under 220V50/60Hz voltage and frequency; When change-over switch is got to the left side, be " 110 " shelves of change-over switch, the B in the change-over switch, C and D, E connect respectively, and two cover 110V main windings are connected in parallel, the main winding of this moment equals the winding of a cover 110V, so make motor to work under 110V50/60Hz voltage and frequency.
Thereby realized of the adjusting of a motor, can under the voltage of 110V or 220V50z/60Hz, work by change-over switch.
Blower fan adopts 110V's, and its terminals insert from the 110V port of motor, promptly are connected on the interface B and interface D of change-over switch.
The utility model advantage is simple and reasonable for structure, easy to use, reclaim in the machine structure at the two compacting of double frequency cryogen, as long as electric machine structure is done change less, adopt a cover special design of motor machine winding and the special mode of connection, in the use,, just can be applicable to 220 volts or 110 volts of two kinds of voltages as long as pull change-over switch gently.Reached product can any one country be used in the whole world.
