MODE OF ELIMINATION OF LEAKAGE IN INTEGRAL TANKS WITH APPLICATION OF ANAEROBIC SEALING MATERIAL AND DEGASSING Russian patent published in 2005 - IPC

FIELD: the invention refers to means of controlling leakage.

SUBSTANCE: the invention is directed on improving quality of reconstruction of tightness, reducing labor-intensiveness and conditions of working with integral tanks. This result is achieved due to the fact that the mode of elimination of leakage in integral tanks includes infilling the channel of leakage from the side of the output of the leakage with anaerobic sealing material by way of drawing it with a brush on the outside surface of the construction. At that increasing of the depth of penetration of the sealing material into the channel of leakage is achieved with the aid of a leak-in at degassing of the integral tanks. Besides degassing of the integral tanks of the aircraft is executed with the aid of a domestic or an industrial vacuum cleaner, the intake hose of the vacuum cleaner is connected to one out of two drainage outputs of the fuel system of the aircraft and the second output is used for attaching it to a manovacuummeter. At that the elimination of leakages is executed immediately after their appearance before flaw detection and repair of the construction. For increasing the reliability of tightness the drawing of sealing material is made two times with an interval of 20 minutes. The moving away of the remaining sealing material after execution of elimination of leakage from the surface of the integral tanks of aircraft is executed with the aid of a napkin.

EFFECT: improves quality of reconstruction of tightness.
