Engines of the ADO-143/70–8-10U3** with a short-closed rotor, are designed to drive units of electric pumps D9000-29, for supplying circulation water for cooling capacitors of steam turbines of power units PSU-235 MW. Delivery to the Sevastopol PSU-TES and Simferopol PSU-TES.
To work in two modes in power and rotation frequency, the engine has two independent windings on the stature. The output ends from each winding are displayed into a separate box of conclusions.
The performance of the engine is horizontal on the paws, with rolling bearings built into the engine. The symbol of the constructive execution of the engine IM1001 according to GOST R IEC 60034-7.
Engine execution by degree of protection-IP55 according to GOST IEC 60034-5.
The engine ventilation is double -circuit. The connection of the cooling circuits is carried out by a fabulous heat exchanger installed on the engine on top. The first circuit is a closed, circulation of cooling air from the ventilation effect of the rotor inside the engine body with washing the outer surface of the heat exchanger tubes. The second circuit is an open, fence of cooling air from the side opposite the working end of the shaft, using a centrifugal fan installed on the engine shaft. Air release - through the heat exchanger tubes from the side end of the engine shaft. The symbol of the engine cooling method is IC611 by
