The experience of establishing vibration diagnostics laboratory

Summary

The equipment life time includes the stage of maintenance and repair. Maintenance and repair control aims at reducing equipment outage and maintenance expenditures. Very often this stage is vitally important for industrial enterprises since maintenance expenditures are rather high. For the Russian enterprises maintenance and repair expenditures can reach 80% of the profit (the average value in USA and Western Europe is 25–30%). Nevertheless, even with these expenditures the failure rate in industry is too high. All the maintenance and repair expenditures are included into the water and sewerage tariff. Considering the social significance of tariff rates more transparent and reasonable repair process must be worked out. The control philosophy improvement, tools of technical control and diagnostics of the equipment condition provided for enhancing the efficiency of equipment maintenance and repair control. However, the operating experience shows that they did not gain widespread currency at the Russian industrial enterprises. In Tumen Vodokanal a vibration diagnostics laboratory has been established that carries out pumping unit vibration control and alignment at the company facilities. The conducted works ensured reducing pumping unit failures and improving the efficiency of cash flow distribution for the equipment repair.
