摘要
分析了传统深海声学释放器存在体积大、重量大、成本高以及电机旋转式声学释放器存在的动密封困难等问题,提出了基于无密封电机的深海声学释放器总体方案设计,将控制电机置于承压密封舱外部以避开动密封困难的难题,并且减小声学释放器的体积和重量,降低成本。确定采用二相混合式步进电机作为声学释放器的控制电机,并从步进电机的结构、材质、工作原理等方面,讨论了深海条件下无密封步进电动机的耐压、绝缘、防腐等问题。经理论分析和盐水槽实验验证,在深海条件下基于无密封电机的声学释放器在中短期时间内可正常工作。
This article analyzes the weaknesses of the traditional deep sea acoustic release transponder,such as great bulk,large weights and high cost and the problems of motive sealing existed in motor rotary acoustic release transponder,and also puts forward a whole scheme design of the deep sea acoustic release transponder based on no-sealing electromotor,which is to put the controlling electromotor outside the pressured sealed cabin to avoid the problem of motive sealing.And it can decrease the size and weight of the acoustic release transponder,and then lower the cost.What＇s more,it decided to use the two phase hybrid stepping motor as the controlling electromotor of the acoustic release transponder,and discussed how to bear pressure,insulate and avoid corrupt when no-sealing electromotor is working in deep sea considering the structure,texture and operating principle of the stepping motor.Through theory analysis and salinity bath experiment results,the acoustic release transponder with no-sealing electromotor working in deep sea within medium and short term is feasible.
