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 many paddlewheel aerators should be used in a shrimp pond? 1. Depending on the stocking density of the shrimps in the pond. If the stocking rate is 30 shrimps/m2, 1 HP should be used in a HA pond with 8 units. 2. Depending on the expected harvesting tonnage. If the expected harvest is 4 tonnes per hectare, four 2HP paddlewheel aerators should be installed in the pond; in other words 1 tonne / 1 unit. How do I maintain the paddlewheel aerators? Motor. 1. After each harvest, the surface of the motor needs to be sanded and brushed off and repainted. This is done to prevent corrosion and to enhance the heat dissipation of the machine. 2. When the machine is running, we need to ensure that the voltage is stable and normal. This is to prolong the life of the product motor. Pressure reducer. 1. The gear lubricant needs to be changed after the first 360 hours of use of the machine and every 3600 hours thereafter. This is to reduce friction and extend the life of the gear reducer. Use No. 50 gear oil with a standard capacity of 1.2 litres. ( 1 gallon = 3.8 litres ) 2. Keep the surface of the gearbox the same as the surface of the motor. High density polyethylene floats. After each harvest, clean the float of dirt organisms. This is to maintain proper depth of submersion and optimum oxygenation.
