One of directions of technical progress in transport is development of pipeline transport. The most perspective is hydraulic transport.
Air-lift – the device representing the hydraulic device for rise or only of a drop liquid, or a drop liquid and a firm material by means of use preliminary compressed in a supercharger and air mixed with this drop liquid. It is open in 1797 by Charles Losher.
It is intended for hydro extraction of uranium, carnalite, oil, the bituminous sand, coal and other minerals. Find application in the coal industry (water pumping), in building business, at mining combines, on Thermal Electrical Plant, rise of minerals from bottom of reservoirs.
Work of the air-lifts is possible at immersing an elevating pipe together with the mixing device in a liquid on size h.
The air-lift installation Deepsea Miner consist of next parts. The equipment for the air-lifts output installations is placed on the specially equipped vessel by displacement 7500 t, length 106 m and width a complex of drain-elevating mechanisms is established is cut. The pipeline of air-lift is section of steel pipes D=0.25 m, l=12 m, an oil assortment. In the bottom part the elevating pipeline with the help of the spherical hinge is connected to the inclined soaking up branch pipe built in the closed metal form. The air pipe and auxiliary communications are fixed by collars in special branch with the elevating pipeline of air-lift.
Advantages: section execution of the elevating pipeline does not limit depth of extraction; the vertical arrangement of the elevating pipeline with elements of the condenser reduces influence of wave influence.
Lacks: rigid connection of the towed unit of gathering with the elevating pipeline reduces a maneuverability of a complex.
