Abstract

The invention relates to the technical field of generator cleaning, in particular to a generator rotor coil water loop pickling device. Due to the structural factor of a generator rotor coil water loop, every time when the water loop is blocked, and is hard to dredge, the water loop needs to return to a factory, a coil is replaced for overhauling, the construction period is long, and the cost is high. One end of a second communication pipe communicates with a second stop valve and a third stop valve, one end of a first communication pipe is communicated with a first stop valve and a fourth stop valve, an air pipe joint is arranged on the second communication pipe, and pickling descaling efficiency is effectively improved. One end of a demineralized water pipe communicates with the upper end of a solution box, one end of a steam pipe communicates with the upper end of the solution box, pickling effect is effectively improved, one end of a bypass pipe communicates with a water turning pipe, the other end of the bypass pipe communicates with a pressure meter and a flow meter, a bypass adjusting valve is arranged on the bypass pipe, pickling pressure stability is effectively ensured, and the device is mainly used for generator rotor coil water loop pickling.

Description

technical field [0001] The invention relates to the technical field of generator cleaning, in particular to a generator rotor coil water circuit pickling device. Background technique [0002] At present, there are quite a few dual-water internal cooling generators among the units in operation in domestic power plants. This type of generator uses water passing through the stator coil and rotor coil at the same time as the cooling method. However, the water circuit of the rotor coil is a copper water pipe. When the cooling water quality is unqualified, scaling will form inside the pipe, the diameter of the pipe will become smaller, and the oxides of the copper pipe will fall off, which will also cause water pipe blockage. In order to avoid abnormalities during generator operation, the stator and rotor coil water circuits must be cleaned and dredged when the generator is regularly overhauled and out of service. Due to the structural factors of the rotor coil water circuit, it ...
