Nutrient solution injection amount by the magnetic pump in the supply of nutrient solution

摘要

this is the amount of the liquid supply device to the shaft of the water of the liquid (liquid fertilizer), the appropriate proportion of mixed additives, to automatically crop the supply to the device. the fluid supply device, the amount of the quantitative injection is more important, especially in a solution and the b solution is the same as the ratio of the quantitative injection., magnetic pump, pump, the performance difference between the uc561uc758 quantitative injection is difficult the fact that . therefore, this design is the use of magnetic pump, pump the performance gap between the two, to make quantitative liquid can be injected.the magnetic tube is the liquid tank from the injection pipe and the suction pipe through the pipe in a certain height (2 - 3M) than the atmospheric pressure, the amount of the liquid in the circulation pipe to maintain a certain speed through the two liquid tanks of the electromagnetic valve to control the opening and closing ub418uba74uc11c quantitative. the amount of the mixture is injected into the tank. so the design of the magnetic pump has some differences, or magnetic pump exchange. two of the tanks is to always maintain a certain air pressure is on the boundary of the volume flow rate of a fluid, uac19uc73c b a quantitative ratio. the amount of mixing tanks can be injected.
