Description

Technical Field

[0002] The internal cleaning hydraulic device for the cooling water pool of a nuclear power plant realizes the thorough cleaning of the inner wall of the cooling water pool through the combination of high-pressure water flow and a specific nozzle, effectively removes the attached dirt, sediment and biological attachments, and ensures the normal operation and efficiency of the cooling system; the high-pressure pump group provides the high-pressure water flow required for cleaning, and according to the size and dirt degree of the cooling water pool, the high-pressure pump group can generate high-pressure water with different pressures and flows;

[0003] After checking the publication number: CN215745118, a self-cleaning device for facilitating the cleaning of a high-pressure pump is disclosed. In this technology, "a self-cleaning device for facilitating the cleaning of a high-pressure pump, a C-shaped slider is sleeved outside the screw rod, a slide rail is fixedly installed on the upper surface of the frame bottom plate of the C-shaped support frame at the bottom of the C-shaped slider, automatic telescopic rods are fixedly installed on the left and right sides of the lower surface of the support plate, a C-shaped clamping seat is fixedly sleeved at the bottom end of the automatic telescopic rod, a connecting rod penetrates through the front and rear side walls of the C-shaped clamping seat, and a cleaning brush is sleeved in the middle of the outer ring of the connecting rod" and other technical solutions are disclosed, and it has technical effects such as "the combined structure of the screw rod with a C-shaped slider and the slide rail added, by rotating the rocker, the C-shaped slider moves left and right along the slide rail, pushing the moving block to move to the right, and the high-pressure pump of different sizes can be fixed by adjusting the position of the C-shaped slider, so that the fixing of the self-cleaning device of the high-pressure pump is more convenient and efficient";
