As bombas convencionais de transporte aéreo têm uma taxa de fluxo muito limitada. 1 Introduction An Air-Lift Pump is a device for raising liquids or mixture of liquids (mostly Although air lifts are used in nuclear fuel reprocessing plants, no general, theoretically sound equation has been proposed in the literature for tall air lift design. Da Wikipédia, a enciclopédia livre. Effect of air injection method on the performance of an air lift pump. Pela flutuabilidade, o ar, que tem uma densidade menor que o líquido, sobe rapidamente. Esta é uma desvantagem dramática em algumas partes de uma pequena estação de tratamento de águas residuais, como o arejador. 0000003478 00000 n endobj 0000168093 00000 n 0000002706 00000 n Ejection Rate of Overflow Generated by Air-Lift Pump at Reduced Pressure.. JOURNAL OF CHEMICAL ENGINEERING OF JAPAN. Simplicity of design, absence of any moving parts, ability to handle muddy water, reliability, ruggedness and low cost, more than compensate for the relatively poor efficiency of the pump, jet pump is the common part of the air-lift pump… and you may need to create a new Wiley Online Library account.
