Diagnostics of pumping units of pumping station of machine water lifting

The purpose of diagnostics is to determine the operability pumping units station machine water lifting at a given time and identify defects in their components. For this reason, article presents diagnostic issues for stations No. 1 - 6 Karshi main canal, designed commissioned 1965-1976, where OPV11-260EG type with electric motors VDS-375/130-24 are installed, vertical units, shaft power – 8010 kW, rated motor 12500 voltage 10.0 kV, stator current 825.0 A, maximum permissible temperature winding 120 O C, bearing no more than 70 C. Diagnostics equipment involves prompt detection malfunctions as result processing sensor readings standard monitoring system, entered manually once day, data from monthly special tests. Technological algorithms vibration thermal similar those developed pumps installed plants, processes being diagnosed which occurring station. Taking into account above tasks, have been diagnosing components whose condition affects performance unit: upper bearing, crosspiece, core, lower guide bearings, bearing. Possible unit ways eliminate them given.
