The article describes the methods to improve the tribological characteristics of friction-trobezhnyh pump prices by applying a composite coating friction-chemical method. It is shown that most of the damage is related to the failure of bearings-ing, or a protective sleeve shaft packing and packing cords, broken down due to hydrogen wear. Reduce the hydrogenation of friction parts as a result of the operation of the water can be considered in the implementation of the friction regime of selective transfer. This can be done by forming a coating of composite processing in metalloplakiruyuschih environments, and using metalloplakiruyuschey additive in the oil. The results showed that the use of lubricants and metalloplakiruyuschih composite coating increases the life of electric heating systems more than doubled.
