1 foreword

Plasma is automatic adjuster of on any account is the equipment of indispensable form a complete set in cut machine, wide application is made at large equipment, the domain such as shipbuilding and cut, its are main the function is to assure cut cutting torch and be maintained optimal by cut workpiece cut distance, eliminate by by cut workpiece rough the treatment precision error that spends change to cause. Cut machine is in working process cannot accurate the distance that gets cut cutting torch and spring, this affects the cut quality of armor plate necessarily. The arc electric current of cut can give operation personnel by force cause visual exhaustion solely. Accordingly, gave out a kind of design program that is based on suddenly Er sensor, width of the kerf in assuring cut process is even, cut precision rises.

2 systems design

This design program uses Huo Er to effect principle generation changes along with magnetic field and produce metabolic tension, send automatic discretion regulator metabolic voltage, the rise that controls cutting torch and drop, form the automatic propriety regulating system of a closed circuit, if pursue,1 is shown. System of automation of this closed circuit by suddenly Er sensor, self check implement, the high frequency filter, operation amplifier, comparator, promotion that break arc implement, imitate switch hand moves each other of door of coupler of automatic converter, photoelectricity, 3 condition to lock up implement, electric machinery driver and mechanical silk lever transfer location system. The graph is shown 2 times is graph of systematic control circuit, can control the distance of cutting torch and armor plate in real time in cut process thereby, assure the cut quality of armor plate effectively.
