Coolant coupling head
Abstract
Abstract A COOLANT COUPLING HEAD FOR THE INTAKE AND DISCHARGE OF A COOLANT IN LIQUID-COOLED ELECTROMACHINE ROTORS IN WHICH A PROTECTIVE GAS CHAMBER IS PROVIDED BETWEEN A COOLANT DISCHARGE POINT AND A SEAL AGAINST THE EXTERNAL ATMOSPHERE. A GAP SEAL IS PROVIDED BETWEEN SUCH PROTECTIVE GAS CHAMBER AND A COOLANT COLLECTION CHAMBER AT THE COOLANT DISCHARGE POINT. BY PROVIDING A COOLANT STORAGE CONTAINER, TO WHICH THE COUPLING HEAD IS CONNECTED, AT A GEODETIC HEIGHT ABOVE THE COUPLING HEAD AND THE COOLANT COLLECTION CHAMBER THEREOF, A CONSTANT AMOUNT OF LEAKAGE BETWEEN THE COOLANT COLLECTION CHAMBER AND THE PROTECTIVE GAS CHAMBER IS MAINTAINED VIA THE GAP SEAL. MOREOVER, THE PROTECTIVE GAS CHAMBER AND GAS ROOMS OF THE STORAGE CONTAINER AND OF A COOLANT RETURN SYSTEM COMMUNICATE ONE WITH ANOTHER AND ARE THEREFORE KEPT UNDER THE SAME GAS PRESSURE.
