DEVICE FOR AUTOMATIC TEMPERATURE CONTROL IN SPACESUIT FOR OUTER SPACE OPERATION

摘要

FIELD: instrument making.;SUBSTANCE: device for automatic temperature control in spacesuit for outer space operation includes water cooling circuit with heat exchanger - sublimator, water pump and electromagnetic valves. Ventilation circuit consists of a fan, an absorbent cartridge, a microcomputer, a gas flow transmitter, carbon dioxide transmitters and a temperature sensor. Outputs of microcomputer are connected to terminals of electromagnetic valves. Water pump consists of a housing, ferromagnetic conductor with primary winding, rotating short-circuited secondary winding separated from magnetic conductor with heat-insulating element from composite antifriction non-conductive material, which serves as a radial thrust sliding bearing. Ends of ferromagnetic conductor are tightly closed with covers. Pressure blades are fixed on inner surface of secondary winding.;EFFECT: improvement of mass and dimensions parameters of the system is provided.;2 dwg
