Knowleage
How is the directly effective depth and effective water length of the paddlewheel aerators? 1. Directly effective depth : 1HP paddlewheel aerator is 0.8M from the water level 2HP paddlewheel aerator is 1.2M from the water level 2. Effective water length : 1HP/ 2 impellers : 40 Meters 2HP/ 4 impellers : 70 Meters During the strong water circulation, oxygen can be dissolved into the water to 2-3 meters water depth. The paddlewheel could also concentrate the waste, splash out the gas, adjust the water temperature and help the decomposition of organic matters.How to maintain the paddlewheel aerator ? MOTOR: 1. After each harvest, sand off and brush away the rust on the surface of motor and repaint it. This is to prevent corrosion and enhance heat dissipation. 2. Make sure the voltage is stable and normal when the machine is in operation. This is to prolong the life of motor. REDUCER: 1. Replace gear lubrication oil after the machine being used for the first 360 hours and once every other 3,600 hours later. This is to reduce the friction and prolong the life of reducer. Gear oil #50 is being used and standard capacity is 1.2 liters. ( 1 gallon = 3.8 liters ) 2. Maintain surface of the reducer as that of motor. HDPE FLOATERS: Clean off the fouling organisms on the floaters after each harvest. This is to maintain the normal submergance depth and optimal oxygenation.How many units of paddlewheel aerators to be used in the shrimp ponds ? 1. According to the stocking density : 1HP should be used 8 units in one HA pond if the stocking is 30 pcs / square meter. 2. According to the harvesting tons : If the harvest expected is 4 Tons per HA should be installed in the pond 4 units of 2hp paddle wheel aerators ; the other words is 1 Ton / 1 unit.
