SU1203391A1 - Method of testing tightness - Google Patents

Description

The invention relates to the field of control of machines and mechanisms, in particular, the field of electrical and inertia, and is intended to detect leakage of water-cooled elements, for example, in electric machines.

The aim of the invention is to demonstrate the accuracy of counter measurement. I am tight.

A method for monitoring the tightness of a nominal-hygrometer dew point is to maintain a predetermined moisture value in a controlled volume using a condensation cooler, to measure moisture content at least at one point of this volume, and to register the measured value of humidity to a specified value. The liquid used by E condensation oh; the consumer is heated by a constant value, and then the heated liquid is iodized as a refrigerant on the mirror of the hygrometer.

Water from the head of the south pipe ROBOD 2 of the condensation cooler 1 io to the tenlo-insulated pipeline 4 with valve 5 is continuously fed to the channel of the gyrometer 6 and drained to the funnel 7 and further to the drain pipe 3 of the cooler 1.
