Abstract
BACKGROUND: The efficiency of operation of hydroficated machines significantly depends on the availability of modern methods and means of diagnosing machines in general and hydraulic systems in particular. The parameters of hydraulic systems of technological machines that change during operation are evaluated by various diagnostic methods that have certain advantages and disadvantages. The choice of diagnostic methods significantly depends on the type, purpose and operating conditions of hydraulic systems, as well as on the equipment of operational units with diagnostic tools.
AIM: Development of a new method for diagnosing hydraulic cylinders. Application of a hardware diagnostic facility for testing a hydraulic cylinder. Analysis of time-domain graphs of pressure. Identification of main diagnostic indicator characterizing the technical condition of the hydraulic cylinder.
METHODS: The pressure, flow rate and temperature of the working fluid are currently used as diagnostic indicators of technical condition of hydraulic systems as a whole and their individual elements. Changes in these indicators makes it possible to judge the state of the hydraulic system of the construction machine. However, these indicators help to assess the current state and, as a rule, are not enough to assess the remaining service life of hydraulic system elements.
RESULTS: The technical state and remaining service life of hydraulic cylinders can be determined by comparing the angle of pressure increase of the reference hydraulic cylinder and of the tested hydraulic cylinder. With the hydraulic support in the drain line, the angle of pressure increase can serve as a diagnostic parameter when determining the technical state of the hydraulic cylinder, makes it possible to determine the change in its technical state.
CONCLUSIONS: The practical value of the study lies in the fact that with the help of a hardware diagnostic facility used together with the developed diagnostic method, it is possible to assess technical state of the hydraulic cylinder. The proposed method of assessing the technical state helps to evaluate the service life of hydraulic cylinders, both on the bench and during their operation. It helps to decrease the downtime of machines, as well as to decrease costs their maintenance and repair.
