FIELD: space technology.
SUBSTANCE: unconfined space of gas chamber of hydro-pneumatic compensator is subject to periodical change at the same average-mass temperature of heat-transfer agent. The ratio of Vi≤(Vi+l+nϕ) 1) is used to judge if leak-proofness corresponds to standard value, where Vi is volume of gas chamber of hydro-pneumatic compensator for i-th measurement, Vi+l is volume of gas chamber of hydropneumatic compensator for subsequent measurement, n is time interval between i-th and i+1 measurement, ϕ is standard value of volumetric loss of heat-transfer agent during specific time interval. Difference in unconfined spaces achieved between (i+1)-th and i-th measurement is used to determine real leakage of heat-transfer agent from system during specific time interval. Current value of unconfined space of system hydro-pneumatic compensator gas chamber is measured instead of measuring working pressure of the system for the same average-mass temperature of heat-transfer agent. Difference between measured spaces related to time interval between measurements has to be value of real leakage of heat-transfer agent observed during specific time interval.
EFFECT: simplified and reliable method of inspection.
