Abstract

The invention discloses a compressed gas filtering and purging device for maintenance, which comprises a filtering tank body and a cover body detachably connected with the filtering tank body through a fixing piece, wherein the surface of the lower end of the filtering tank body is provided with an air inlet pipe communicated with an inner cavity of the filtering tank body, an air inlet valve is arranged on the surface of the air inlet pipe, the upper side of the cover body is provided with an exhaust pipe communicated with the inner cavity of the filtering tank body, the other end of the exhaust pipe is communicated with a purging assembly, a gas distributor, a gas-liquid separator, a filtering plate and an adsorption plate are hermetically clamped in the inner cavity of the filtering tank body in sequence from bottom to top, and a pressure gauge and a pressure regulating valve are respectively arranged at the upper end of the cover body. According to the invention, compressed air is filtered, meanwhile, the filtering quality is high, the situation that a purging piece is damaged due to the fact that exhausted compressed air contains impurities is avoided, the usage amount of the compressed air is reduced, and meanwhile, the maintenance cost of a water-cooled generator is saved.

Description

technical field [0001] The invention relates to the field of inspection and maintenance of double-water inner-cooled generators, in particular to a compressed gas filter and purge device for inspection and maintenance. Background technique [0002] Both the stator and the rotor are water-cooled generators, which are called dual-water internally-cooled generators. The core of the dual-water internally-cooled generator is air-cooled. Under the action of fans at both ends of the rotor, the air enters the air through the ends of the stator windings Then the ventilation groove of the stator core collects the hot air area, after being cooled by the air cooler, it enters the negative pressure area of ​​the fan from the air ducts on both sides to form the circulation of the air circuit. During the process, the insulated cooling water pipe needs to be cleaned with compressed gas, and the compressed gas for maintenance is taken from the compressed gas pipeline. [0003] Due to the lo...
