目前使用量最大的渔业机械是增氧机,它已经成为池塘养鱼不可缺少的设备。从各地使用情况来看,普遍存在着开机时间长的问题,有的全天开机十多个小时,电能浪费严重。选择最佳开机时间是节电的有效措施。根据我们几年的实践,在以下三个时间开机,时间从6～10小时减少到3～5小时,可以节约用电50％左右,而且保证鱼类正常耗氧。①黎明前开机此时气压较低,鱼类及各种动植物已经一夜耗氧,开机1～2小时,使池水中溶氧量恢
Currently the most widely used fishery machinery is aerator, it has become an indispensable equipment for fish ponds. From all over the use of the situation, the widespread problem of long boot time, and some boot more than 10 hours throughout the day, a serious waste of electricity. Select the best boot time is an effective measure to save energy. According to our practice for a few years, it will start up in the following three time periods, reducing the time from 6 to 10 hours to 3 to 5 hours, saving about 50% of electricity consumption, and ensuring the normal oxygen consumption of fish. ① pre-dawn start at this time the pressure is low, fish and all kinds of plants and animals have oxygen overnight, boot 1 to 2 hours, so that the dissolved oxygen in the pool of water
