The invention discloses a tightness test method for an energy converter cable tube. The tightness test method specifically comprises the following steps: mounting the energy converter cable tube; performing first tightness test on the energy converter cable tube; mounting a cable on an energy converter in the energy converter cable tube; performing second tightness test on the energy converter cable tube; and pouring sand into the energy converter cable tube from a port of a cable branch tube. The tightness test method disclosed by the invention has the benefits that through respectively fixing flanged stuffing boxes at the upper end part and the lower end part of a cable main tube, not only can the cable tube be sealed, but also the disassembly of the cable in the tube can be facilitated;the cable tube in which the cable is laid can be subjected to tightness detection, and the test pressure of 0.015-0.02 Mpa introduced during the detection cannot damage the cable performance, so thatthe cable tube tightness test accuracy is improved, and the service life of the cable is prolonged.
Description
technical field [0001] The invention relates to the technical field of ship airtightness detection, in particular to a method for testing the airtightness of a transducer cable tube. Background technique [0002] In the process of ship construction, cables are usually laid in continuous cable pipes, and some areas of the ship have certain requirements for the airtightness of the cable pipes. At present, in the actual construction process of the ship, it is relatively easy to test the airtightness of the cable pipe, but after the cable is laid in the cable pipe, the airtightness of the cable pipe cannot be tested, the airtightness test result is inaccurate, and the test pressure Difficult to control and can damage cable performance if test pressure is not properly controlled. Contents of the invention [0003] The purpose of the present invention is to overcome the deficiencies of the prior art, design a kind of tightness test method of the transducer cable tube, solve the...
