FIELD: mechanical engineering. ^ SUBSTANCE: invention can be used in friction units operating under heavy conditions, for instance, in wear-resistant submersible pumps. Proposed friction pair in stage of submersible multistage centrifugal pump consists of two parts, one of which is made of metal, and the other, of composite material consisting of filler and binder. Binder consists of thermoplastic polymeric material. ^ EFFECT: provision of friction pair of higher stability and reliability. ^ 1 dwg |
