Abstract:
An aluminium disc was put inarotating megnetic field.Due to mutual effect of eddy current in the disc and the megnetic field,the disc was rotated and drove a piston vacuum pump and in turn negative pressure was generated,This is the principle of our decompressor.The suction of the decompressot can be ad- justed when necessarty and displayed by a negtive pressure indicator.The auto- matic stop and alarm system have been designed.When the bottle is full the system will stop the pump and give an alarm immediately in ortder to protect the mecha- nismic parts from being damaged.
