A Drainage System of Generator Large Shaft Air Supplement Pipe

Abstract

The invention discloses a large shaft air supply pipe drainage system for a generator, which comprises a rotating shaft air supply pipe and a generator cover floor; the air inlet of the rotating shaft air supply pipe runs through the generator cover floor and is located above the generator cover floor; An annular support plate is arranged above the floor of the generator hood; a guide rod and a push-pull rod are arranged on the upper side of the annular support plate; an upper pressure plate is arranged at the air inlet of the rotating shaft; the upper end of the guide rod and the push-pull rod output The shafts are all connected to the upper platen; the upper end of the guide rod and the output shaft of the push-pull rod and the upper platen are connected with threaded caps; the upper platen is provided with a guide tube; the guide tube communicates with the air supply pipe of the rotating shaft. By setting the diversion pipe, the water emerging from the air supply pipe of the rotating shaft is diverted to the leakage drainage collection well, so as to prevent the water from the air supply pipe of the large shaft from entering the top of the generator, and effectively prevent water from entering the top of the generator.

Description

technical field [0001] The invention belongs to the technical field of generator equipment, and in particular relates to a drainage system for a large shaft air supply pipe of a generator. Background technique [0002] A hydroelectric generator is a generator that uses a water turbine as the prime mover to convert water energy into electrical energy. When the water flows through the water turbine, the water energy is converted into mechanical energy, and the rotating shaft of the water turbine drives the rotor of the generator, which converts the mechanical energy into electrical energy and outputs it. It is the main power equipment for generating electric energy in hydropower stations. When the precipitation level of the reservoir discharges flood and sand during the flood season, the hydro-generator unit needs to be shut down to avoid sand. When the hydro-generator unit is shut down or in the process of starting up, because the draft pipe of the unit is blocked by sedimen...

Problems solved by technology

When the precipitation level of the reservoir discharges flood and sand during the flood season, the hydro-generator unit needs to be shut down to avoid sand. When the hydro-generator unit is shut down or in the process of starting up, because the draft pipe of the unit is blocked by sediment, there is a phenomenon that the large shaft air supplement pipe leaks water , It is easy to cause hidden dangers of generator accidents caused by flooding
