FRICTION PAIR IN SUBMERSIBLE RADIAL FLOW PUMP STAGE |
摘要 |
FIELD: engines and pumps. ^ SUBSTANCE: friction pair comprises one part made from metal (distributor) and second part made from composite material consisting of thermoplastic binder and filler (antifriction washer). Filler comprises fiber glass, mineral substances, solid grease fillers from fluoroplastic, molybdenum disulphide or graphite. Second part is made from composite polymer material comprising additionally fluorine organic surfactants that represent derivatives of isobutene with fluorine-containing organic substituents. Fluorine organic surfactants form protective layers on contact surface facilitating operation in non-flow lubrication conditions. Formation of protective layers occurs with heat absorption from contact zone. Washer is fitted in through bore of impeller cover in contact with metal disk arranged between impeller disks and rigidly jointed therewith for surplus heat rejection. ^ EFFECT: higher wear resistance. ^ 2 cl, 1 dwg |
