AB - INFORMATION UDC 621:66.002.2 Turboexpander Block RT-29/6 The expander is designed for cooling of compressed air in the cooling cycle of an air distributor. It consists (Fig. 1) of a turboexpander, an electric motor, a reducer, a casing, and an oil tank. The turboexpander is a jet-type radial centripetal turbine. The air flowing along the chalmels of the guide equipment and the impeller of the turbine, is expanded and transmits energy to the impeller fixed to the cantilever part of the shaft of the high-speed gear of the reducer. The energy is transmitted via the reducer to the electric motor operating under generator regime. The cooling capacity of the turboexpander is controlled by rotation of the blades of the guide equip- ment, which are set in motion by the rotating mechanism. The rapid-acting centrifugal switch acts through a pneumatic system on the cut-off valve interrupting admission of air to the turbine in case of excessive rise in the impeller speed. The oil lubrication system of the bearings and the reducer gear is of the forced-circulation type with forced cooling and filtration. The turboexpander with the oil pump is mounted on a single frame housing the oil tank. The electrogenerator is
