Reliability technologies, RCM analysis, analysis of equipment maintenance Reliability

Training center of excellence and retraining "Baltech" on the basis of the license # +1872 for the implementation educational activities, issued by the Committee for education of St. Petersburg Government, conducts training of managers and specialists on the program of ADDITIONAL EDUCATION "The concept" reliability Technologies "- technologies Reliability - Methodology RCM-analysis ". Maintenance-oriented reliability, allows us to calculate from the point of view of economy and reliability equipment most appropriate form of maintenance: the maintenance to failure (reactive or responsive service), service schedule (planned preventive) maintenance of status (based on the actual technical condition of the equipment), proactive services (except recurring causes of equipment failure).

Methodology RCM(reliability the technical service centre) - better known in the West as technology Reliability or "the Concept" reliability Technologies is an effective and simple solution of the system MRO calculation (maintenance and repair). The choice of the form of technical maintenance is carried out on the basis of calculations and statistics.

The simplicity of the calculation using the methodology of RCManalysis of the "Concept" Technology reliability of Reliability can be illustrated by a simple example calculation of the coefficient of readiness of equipment which is likely to be in working state in each moment of time, excluding planned periods when using equipment not provided ,

For example, the COMPRESSOR worked for 947 days according to the following schedule:

1) Calculate the average time between failure (mean time between failures) = MTBF

Average uptime (average time between failures (MTBF)) = (200 + 360 + 200 + 120) / 4 = 232,5 days

2) Next, calculate the average recovery time (Mean time to repair) = MTTR

MTTR (mean time to repair) = (9 + 6 + 2) / 3 = 5,67 day

3) Further, according to the Formula calculate Ratio readiness (availability) = MTBF / (MTBF + MTTR)

Availability (availability) = 232,5 / (232,5 +5,67) = 97,62%

In accordance with the requirements of methodology RCM (methodology of RCManalysis of the "Concept" Technology reliability technology Reliability), when considering the main the reliability of each item of industrial equipment, part the technical installations (e.g. motor, pump, compressor or a separate part or subassembly) special attention is paid to the factor readiness, which is associated with the value of failures and takes into account average recovery time. To estimate the average idle time between shutdowns related to THE product group carried out a comparison of the coefficient of readiness. Statistics calculation is that if the availability (presence) will have a value less than 90%, the necessary emergency measures to support the healthy state equipment because with a probability of 1:10 equipment will be unusable! The main specifics of the company Baltech is to assess the condition of equipment and the development of measures to improve reliability and availability of equipment to work in an arbitrary point in time. The probability of failure of equipment in accordance with GOST R 27.002-2002 should be within 95% -99%, in this regard, it is necessary constantly carry out not only statistical calculations of service history equipment, but also to carry out continuous monitoring of the technical condition of the equipment.

The Baltech almost 20 years since its founding, introduces the industrial enterprises of the Russian Federation Ukraine, Belarus, Uzbekistan, Turkmenistan and Kazakhstan, technical service focused on reliability. Accumulated during this time statistics allows us to conduct analysis of equipment defects using progressive types NTD (non-destructive testing and technical diagnostics), such as oil analysis, thermography, vibration analysis and webroyalty equipment. Department of technical service of Baltech" certified as Laboratory non-destructive testing (Certificate of attestation №58А050798) holds the survey on the actual condition of the equipment with the issue of a statement of reasons for denial equipment and makes recommendations (including development of the programme of activities) increase its reliability. The construction of patterns of failure (charts of distribution of failure probability) takes a long time and for the right trending must be perfect diagnostic equipment.

At the moment there are many software ensure to conduct EAManalysis (software security), but even the perfect software will be need information about the technical condition of the equipment. Unique devices, systems and the equipment by "Baltech" company for solving problems ensure reliability of dynamic equipment allow us to get all the necessary information to make these calculations. One of the main advantages the use of equipment Baltech is a universal software BALTECHexpert to conduct a common base Real figures may differ: vibration, temperature, and other parameters. Software software BALTECH-Expertis simple and reliable tool for expert
