Scope - radial bearings:
bearings horizontal rotary machines (turbines, exciters, network and feed pumps, draught mechanisms of thermal and nuclear power plants, horizontal units HPP, agregaty oil and gas pumping stations, and so on) !
the guide bearings of the vertical rotary machines (HPP hydro units, motors, circulation pumps, thermal and nuclear power stations, pumps, irrigation canals, vodopadov and so on) Bearings with liners VEMP is a NEW GENERATION of bearings. Design features-VEMP and EMF liners have a coating thickness of 9 mm, representing a composite material consisting of two layers: the antifriction bearing. The anti-friction layer thickness of 2 mm made of elastic material is PTFE. The supporting layer is made of elastic material-metal. End surface of the friction-thrust liners are removable semiring.
Advantages VEMP over conventional liners with the Babbitt surface friction:
- have elastic vibrationproof surface with high friction protivosudorojnami and electrical insulation properties and a low coefficient of friction;
- less sensitive to the accuracy of installation of the liner, to beatings, to the distortions and deviations from the cylindricity of the shaft;
- dramatically reduce the contact stresses in the zone of friction during start-up;
- reduce by 10-15 dB vibration in the frequency range of 500-2, 000 Hz.;
- prevent jamming and damage to the shaft journal in an emergency situation (at the termination of the admission of lubricant to the friction zone).
The advantages of EMFs liners provide bearings unique bearing capacity, high reliability and durability in operation, minimum costs of installation and operation, which is confirmed by tests and operating experience.
