超声波增氧系统研究进展
摘要:氧是鱼类赖以生存和生长发育的必备条件之一,水中含氧量主要与自然温度、湿度以及鱼体的密度有关。如今家用鱼缸在日常生活中越来越普及,但由于鱼缸体积小,水内溶氧量较小,特别是在炎热的夏天,溶氧量的减少会使鱼上浮水面吸氧,鱼体能消耗大,长期后还可能导致鱼的生病及死亡。超声波增氧系统对鱼类养殖有着积极意义,但目前仅发现少数国家将超声波用于渔业上。超声波增氧原理是利用超声波的空化现象,将雾状的气泡喷入水中,使其有更长的时间与水充分混和,从而达到增氧目的。该系统是由超声波传感器构成的鱼缸自动增氧控制系统,该系统可根据鱼儿的活动情况,自动检测鱼缸水中是否缺氧,从而开启/停止增氧装置,以使鱼缸水中的氧浓度保持在最佳状态。

The fish bowl increases the oxygen system design automatically
Abstract:Oxygen is one of the necessary conditions for fish survival and oxygen content in water is main of natural temperature, humidity and the density of the larvae household aquarium in daily life increasingly popular, but because of the small volume of the aquarium and the small dissolved oxygen in water, especially in hot summer,oxygen reduction will make fish up-floating surface oxygen,then fish can increase the consumption of oxygen and food,it will lead to fish death at ultrasonic add oxygen system for fish breeding has positive significance,but currently only found a few countries on ultrasound for add oxygen principle is to use ultrasonic cavitation phenomenon,make fog shape bubbles spray into the water,then make it a longer time for water fully mixing,so as to achieve the goal that add posed of by ultrasonic sensors increasing oxygen tank automatic control system,The system can according to the activ
