Abstract

A transverse tube-type cooling tower with a leakage testing and overhauling function comprises a cooling tower body, wherein a low-temperature water inlet tube and a low-temperature water outlet tube are respectively and correspondingly arranged on the cooling tower body, and a cooling water inlet short connector is arranged on the low-temperature water inlet tube, and is connected to a transparent rubber tube. The overhauling and leakage testing method provided by the invention is as follows: the free end of the transparent rubber tube is lifted to the position of a low-temperature water outlet of the lower-temperature water outlet tube, and water irrigation to the transparent rubber tube is performed; the low-temperature water inlet valve is opened so as to irrigate to a low-temperature water section; the low-temperature water inlet valve and the low-temperature water outlet valve are closed, and variation of liquid level inside the transparent rubber tube is observed; and when liquid level inside the transparent rubber tube is no longer changed, the leakage point position of a to-be-detected tube layer of the transverse tube-type cooling tower can be determined according to the liquid level inside the transparent rubber tube. The transverse tube-type cooling tower provided by the invention has a novel structural style, is convenient to operate and use, can effectively and accurately judge the positions of leakage points, and can be used for detecting without demounting a transverse tube wholly.
