Diagnosis, monitoring, prognostics bearing assemblies, gears, steam engine friction, transport, mining equipment
On-board acoustic emission diagnostics system of bearing units is intended for the constant control monitoring of axle boxes and operating generator bearing units 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 12-channel system (for a passenger carriage with an undercar electricity generator) and system cost in case of equipping carriage pilot batch is specified at the contract conclusion.
|PRESENT CARRIAGE PREVENTIVE MAINTENANCE SYSTEM||ON-BOARD DIAGNOSTICS SYSTEM ADOPTION FOR PASSENGER CARRIAGES|
|Periodic preventive maintenance and repair work costs with present maintenance system TO-3→TR→DR→KR are ≈ 600,000 roubles per carriage a year, out of which 10-15 % (≈ 90,000 roubles) are wheelpairs and undercar gears maintenance costs.||On-board diagnostic system allows to reduce unreasonable expenses, thereby units maintenance estimated expenditures according to their actual condition will be ≈ 20-25 % (≈ 20,000 roubles). Hereby annual saving rate will be SR= 90-20 = 70,000 roubles per equipped carriage.|
|Lubricant costs with the present lubricating system (at the cost of 1 kg of BUKSOL lubricant 50 roubles) are ≈ 30,000 roubles per carriage 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 % ( ≈ 15,000 roubles per carriage a year). Hereby annual saving rate will be SR = 30-15 = 15,000 roubles per equipped carriage.|
|Preventive maintenance costs according to structure TO-3→TR→DR→KR with the existing norms of overhaul life are ≈ 945,000 roubles per carriage a year.||On-board diagnostics system of bearing units adoption allows to increase overhaul life by 20-25 % of the existing norms (≈ 750,000 roubles per carriage a year). Hereby annual saving rate will be SR = 945-700 = 245,000 roubles per equipped carriage.|
TOTAL ANNUAL SAVING RATE
|Per equipped carriage||SR= 70+15+245=331,000 roubles|
|Per wagon depot (with the average rolling stock of 300 carriage units)||SR=331 х 300=99,300,000 roubles|
|Per wagon depots network (8-10 wagon depots)||SR=99,3 х 10=993,000,000 roubles|
