Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of water-cooled magnet, in particular to a Bitter type water-cooled magnet coil cleaning device, a water-cooled magnet and a cleaning method. BACKGROUND

[0002] Magnet devices that generate strong magnetic fields can be divided into three types: water-cooled magnets, superconducting magnets and hybrid magnets. Bitter type water-cooled magnets are a kind of device that generates super-strong magnetic field by a plurality of water-cooled magnet coils cooled by deionized water. Figure 4 The structure of the Bitter type water-cooled magnet coil is shown, which is formed by connecting a plurality of Bitter sheets 31 and fasteners 32. The insulating sheet is located above the Bitter sheet 31, and the Bitter sheet 31 is filled with cooling water holes and has a partition seam; the size of the insulating sheet is usually one-tenth to one-tenth of the size of the Bitter sheet 31, and has cooling holes consistent with the Bitter sheet 31.

[0003] The Bitter sheet of the Bitter water-cooled magnet is plated with silver. It is found through experiments that the silver plating layer on the cooling holes and the inner and outer periphery of the Bitter sheet will gradually fall off under the impact of high-speed cooling water, generating about 10 nanometer silver powder particles. Under the super-strong magnetic field, these silver powder particles will be attracted and gathered near the water passage of the coil end plate and the Bitter sheet, resulting in poor water flow of the Bitter water-cooled magnet coil, further leading to insufficient cooling, high coil monitoring voltage, and even causing the magnet to be unable to run or even be burned out.

[0004] However, when the coil monitoring voltage is high, the usual way is to disassemble the entire device, clean the thousands of Bitter sheets, and then reassemble. This method can repair the magnet, but it takes at least three months, which seriously affects the subsequent scientific experiments of the water-cooled magnet. Therefore, how to quickly clean the water-cooled magnet coil has become a problem to be solved for the normal operation of the water-cooled magnet device. SUMMARY
