Description

A significant increase in the efficiency of the equipment used is achieved through the introduction of modern methods and means of technical diagnostics. Technical diagnostics makes it possible to increase the overhaul life of units and assemblies, prevent the dismantling and disassembly of units and individual mechanisms, reduce downtime for technical reasons, reduce the labor intensity of maintenance and operating costs, which significantly increases the efficiency of the use of equipment. Technical diagnostics makes it possible to control the technical condition of machines during operation and predict their service life until the next repair in accordance with the indicators obtained. It allows not only to assess the technical condition of the units and assemblies of machines, but also makes it possible to determine the volumes and types of necessary work using in-place methods. The main tasks of technical diagnostics are: control of the technical condition for compliance with the requirements of technical documentation; search for the causes of failure (malfunction); collection of initial data for forecasting the technical condition; maintaining machine reliability.
