34-29 MENTENANȚA SISTEMELOR DE ACȚIONARE HIDRAULICĂ PRIN DIAGNOZĂ VIBROACUSTICĂ

MAINTENANCE OF HYDRAULIC DRIVE SYSTEMS VIA VIBROACOUSTIC DIAGNOSIS
The aim of the article is to presents some of the experimental results regarding the noise and vibration levels of different types of hydrostatic equipment’s in working. Vibration diagrams and acoustic spectra are measured in order to obtain a functional database of well-functioning diagrams so that to be compare with the diagram of malfunctioning hydrostatic equipment. The goal is to have a maintenance instrument in hydraulic drive systems diagnosis.
Keywords: vibroacoustic diagnosis, maintenance, hydraulic drives, reference model
Cuvinte cheie: diagnoză vibroacustică, mentenanță predictivă, mentenanță preventivă, acționare hidraulică, model de referință

32-9 AVANTAJELE, ERORILE ȘI LIMITELE TERMOGRAFIERII ÎN INFRAROȘU UTILIZATĂ LA MENTENANȚA SISTEMELOR DE ACȚIONARE HIDRAULICĂ

THE ADVANTAGES, ERRORS AND LIMITATIONS OF INFRARED THERMOGRAPHY METHOD USED TO THE MAINTENANCE OF HYDRAULIC DRIVE SYSTEMS

 

The subject of the article is to discuss the advantages, errors and limitations of infrared thermography which can be used as a non-invasive modern method of diagnosis even in industrial applications. The method of infrared thermography diagnosis is proposed to be applied in the preventive maintenance of hydraulic drive systems.

 

Keywords: infrared thermography, preventive maintenance, hydraulic actuators, errors, calibration

29-48 PROBLEME DE MENTENANŢĂ SPECIFICE SISTEMELOR DE ACŢIONARE HIDRAULICĂ

SPECIFIC ISSUES FOR MAINTENANCE OF
HYDRAULIC DRIVE SYSTEMS
This paper presents the concepts of maintenance in the light of ISO’s
standards and EU directives implemented in Romania after the year 2007, in
the industrial field, with reference to the hydraulic drive systems. The
maintenance of these systems can only find a practical solution in accordance
with the international standards and European directives mentioned above.
Keywords: tree maintenance, total productive maintenance, hydraulic
actuators, standards
Cuvinte cheie: arbore mentenanță, mentenanţă productivă totală,
acţionări hidraulice, standarde
