Abstract
The invention relates to a method for cleaning a cooling water pipeline used for a transformer. The method comprises the following steps of: firstly pressurizing dilute hydrochloric acid of which a PH (Potential of Hydrogen) value is 3-4.5; entering from the water inlet of the cooling water pipeline used for the transformer; maintaining a pressure of 0.5-0.8 Mpa and a flow speed of 1.5-2.5 m/s, and staying for 2-5 minutes; monitoring a PH value of outpoured liquid at the outlet location of the cooling water pipeline used for the transformer; and only needing to inlet clear water from the water inlet of the cooling water pipeline used for the transformer when the PH value of the outpoured liquid reaches to 6-7. Calcium carbonate and other impurities and scale substances in the cooling water pipeline used for the transformer can be effectively removed by adopting the method provided by the invention; moreover, the method is convenient and simple.
Description
Technical field
The present invention relates to the cleaning method of a kind of transformer with cooling water pipeline, particularly single crystal growing furnace heating transformer.
Background technology
At present, single crystal growing furnace becomes the hollow copper cash that winding adopts with the cooling water pipeline that uses in the heating transformer like pair, through cooling water, takes the heat that electric current produces out of in winding at work, dispels the heat; Because service life and water quality, the hollow inwall of hollow copper cash can form the incrustation scale of one deck calcium carbonate and other impurity, obstructs the heat of winding to distribute; Equally, single crystal growing furnace also is like this with the IGCT chuck that uses in the heating transformer.Generally, adopt to increase hydraulic pressure, utilize the way of compressed air rinsing to solve, but poor effect long because of the winding circuit, former thereby actual cleaning such as pipeline is thin, fouling is tight.
Summary of the invention
The purpose of this invention is to provide and have a kind of transformer that effectively to remove calcium carbonate and other impurity dirt thing cleaning method with cooling water pipeline.
The technical scheme that the present invention takes is: a kind of transformer is with the cleaning method of cooling water pipeline; It is characterized in that earlier pH value is pressurizeed at 3～4.5 watery hydrochloric acid; Get into from the water inlet of transformer with cooling water pipeline; Keep-up pressure at 0.5～0.8Mpa; Flow velocity is 1.5～2.5m/s; And, when the pH value of trickle reaches 6～7, get final product from the water inlet feeding clear water of transformer with cooling water pipeline at the pH value of transformer with the exit monitoring trickle of cooling water pipeline.
Described pH value is a normal temperature in the temperature of 3～4.5 watery hydrochloric acid under normal conditions, under the transformer situation thick and many with the dirty thing of cooling water pipeline, should be warming up to below 65 ℃ from normal temperature.
Described watery hydrochloric acid transformer with the time that rests in the cooling water pipeline at 2～5 minutes.
Adopt the present invention, can effectively remove transformer with the calcium carbonate in the cooling water pipeline and other impurity dirt thing, convenient simple again.
