On-board acoustic emission diagnostics system of wheel-motor blocks is intended for the constant complex control of operating electric locomotive wheel-motor blocks condition; it allows to:
Developer: OOO METKATOM.
System blocks delivery, personnel training, technology of diagnosis.
System delivery and installation is performed within three months.
The cost of on-board 36-channel system (for a 6-axle electric locomotive) with account of installation and personnel training is included in the contract. System cost in case of equipping locomotive pilot batch is specified at the contract conclusion.
PRESENT LOCOMOTIVE PREVENTIVE MAINTENANCE SYSTEM | ON-BOARD DIAGNOSTICS SYSTEM ADOPTION FOR LOCOMOTIVES |
Periodic preventive maintenance and repair work costs with present maintenance system TO-3→TR-1→TR-2→TR-3→SR are ≈ 1,600,000 roubles per locomotive a year, out of which 35-40 % (≈ 640,000 roubles) are KMB and TED elements maintenance costs. | On-board diagnostic system of bearing units allows to reduce unreasonable expenses, thereby units maintenance estimated expenditures according to their actual condition will be ≈ 20-25 % (≈ 130,000 roubles). Hereby annual saving rate will be SR= 640-130 = 510,000 roubles per equipped locomotive. |
Lubricant costs with the present lubricating system (at the cost of 1 kg of BUKSOL lubricant 50 roubles) are 65,000 roubles per locomotive a year. | Bearing units lubrication according to their actual need allows to reduce unreasonable operations of lubricant final squeezing and reduce lubricant consumption by 45-50 % ( ≈ 35,000 roubles per locomotive a year). Hereby annual saving rate will be SR = 65-35 = 30,000 roubles per equipped locomotive. |
Preventive maintenance costs according to structure TO-3→TR-1→TR-2→TR-3→SR with the existing norms of overhaul life are 2,205,000 roubles per locomotive a year. | On-board diagnostics system of bearing units adoption allows to increase overhaul life by 25-30 % of the existing norms (≈1,545,000 roubles per locomotive a year). Hereby annual saving rate will be SR =2205 -1545 = 660,000 roubles per equipped locomotive. |
TOTAL ANNUAL SAVING RATE |
|
Per equipped locomotive | SR= 510+30+660=1,200,000 roubles |
Per locomotive depot (with the average rolling stock of 150 locomotive units) | SR=1,2 х 150=180,000,000 roubles |
