SYSTEM FOR PROTECTING TURBO-COMPRESSOR AGAINST SURGING

摘要

FIELD: compressor engineering. SUBSTANCE: system has device 7 for limiting capacity and pressure. Device 7 is connected with starting device 5, delivery pressure pickup 3 and starting device 8. Device 7 has transducer of a flow meter with normally-closed contact and relay with normally-open contacts. The delivery pressure gauge is made up as an electric contact pressure gauge with normally-open contact. EFFECT: enhanced reliability. 3 cl, 3 dwg
