Service equipment of the heat sources taken by supervision consisted of centrifugal water pumps, blast air fans and exhausters. Robust and fail safe operation of the heat sources is impossible without the effective operation of this service equipment. Malfunctions of the service equipment resгде in disruption of heat supply, losses and emergencies. Consequently, to provide a robust operation of the equipment there were found the impending failure, classified and described. The main type of the electric engines used for the electric drive of the working organs of the service equipment are asynchronous electric drives with a short-circuited rotor which is mostly exposed to the external influence. In this work there are collected and analyzed reasons of fault inception of the service equipment as well as methods to define the complex parameter of technical state is developed and its functional dependence on failure interval is set. The acquired data may be used to define the readiness of the equipment for operation to the coming period as well as plan its maintenance operation and overhaul.
