3/29/2024 0 Comments Performance tube bendingA series of experiments on a model airlift pump with three different riser tube configurations, based on the vertical position of local bends, were carried out. This work investigates experimentally the effects of local bends of the riser tube on the airlift pump performance. However, in real life situations, the use of local riser tube bend or flexible riser tubes is considerably unavoidable. Conventionally, airlift pump with bent riser tube is less efficient than that with vertically straight riser tube. The geometrical parameters include pipe diameter, pump height, design of air injection system, and entrance geometry of the lifting pipe while the operational parameters involve submergence ratio, conditions of injected air, and nature of lifted phase. The performance of airlift pump is affected by two sets of parameters the geometrical and operational parameters. Sometimes, it is used for removing water from mines or pumping slurry of sand and water or other solutions. Airlift pump is a type of deep well pumps.
