Water-cooled generator flushing device

Abstract

A water-cooled generator flushing device comprises an air and water mixing tank, a flushing water entry pipe, a compressed-air vent pipe. The flushing water entry pipe is inserted in the air and water mixing tank; the compressed-air vent pipe is inserted in the air and water mixing tank, an air distributing pipe is arranged at one end in which the compressed-air vent pipe is inserted into the air and water mixing tank, and the air distributing pipe is of a cone structure and is provided with a smaller head end which is connected with the compressed-air vent pipe; a leading out pipe is arranged on the air and water mixing tank. The water cooling process of repeated forward injection of water, reverse blowing off of compressed air and accessing for cleaning is simplified, flushing efficiency is improved, flushing time is shortened, and the problem about no flushing effect most of the time during reverse blowing off flushing water by the compressed air can be solved with continuous water flushing. Under the condition of tight overhaul period, thorough cleaning of a water system can be completely done; external pipeline connection is simplified, the flushing process is free of frequent operations, and labor force is saved.

Description

technical field [0001] The invention relates to the technical field of generator maintenance equipment, and more specifically relates to a washing device for a water-cooled generator. Background technique [0002] The cleanliness of the water circuit of the water-cooled generator coil is extremely important. Although the water system has adopted a series of measures to ensure the smooth flow of water, it is inevitable that dirt will accumulate at the corners, bends, shrinkages, etc. After a long period of operation, it may be damaged. The flow is reduced or partially blocked. Therefore, in order to ensure the safe operation of the generator and the smooth flow of the waterway, it must be combined with maintenance and flushing. [0003] The water-cooled generator set in the prior art generally adopts the factory-designed and installed stator coil water circuit backwashing pipeline system or uses compressed air to accelerate the water flow backwashing method. [0004] The bac...

AI Technical Summary

Problems solved by technology

However, during the flushing, the process of forward water injection, reverse compressed air blowing and re-introduction of clean cooling water is repeated, the flushing efficiency is low, and the flushing takes a long time; the maximum pressure of the positive flushing cooling water is 0.15MPa, there is almost no positive flushing effect, and the reverse compressed air blowing time is about 10 minutes, and during this time, most of the time, due to the little water in the waterway, there is almost no flushing effect on the waterway; inside the waterway, such as coils, When the attached dirt formed on the inner wall of the water pipe is serious and has nothing to do with the direction of water flow, longer flushing time is required. Generally, the cleanliness requirements of the water system cannot be met after flushing, and it cannot be completed when the maintenance schedule is tight. Thoroughly clean the water system; external connection pipelines are required, and there are many pipeline connections, and frequent operations during the flushing process seriously affect the flushing progress
