Problems of reliability of mechanical equipment of hydraulic structures

Martenson, I. V.

Conclusions When creating mechanical equipment of hydraulic structures it is necessary to take into account not only the one-time expenditures on its creation and assembly but also its operational reliability, maintainability, annual costs for upkeep and repair of equipment, labor efficiency, and working conditions of the operating personnel.One of the ways to increase the reliability of mechanical equipment is to develop standard criteria of its condition, such as longevity, technical life, no-failure operation, maintainability, keeping qualities, etc., which permit a confident determination of the actual reliability indices and prediction of its operational capability.For developing the said criteria, determining numerical reliability indices of operating equipment, and determining the regularities of the change of these indices with time or as a function of the actual cumulative operating time of the equipment, it is necessary to generalize the available and collect missing data on the actual condition of mechanical equipment, its operation, and repair.To increase the quality of evaluating the technical condition of mechanical equipment it is necessary to develop on the basis of technical diagnostic principles a method of evaluating the actual condition of equipment (with an indication of the composition of inspected elements for various types of equipment, criteria of their evident and indirect diagnosis, etc.) and instructions on predicting its further operational capability.It is necessary to create portable diagnostic and monitoring and measuring equipment for conducting inspections in a volume sufficient for an objective evaluation of the condition and for predicting the actual reliability indices of mechanical equipment.
