Indicator of defects in bearings of electrical machines IDP-07


IDP-07 – is a portable device designed for monitor vibration of electrical and other rotary machines, the condition of their rolling bearings.
IDP-07 provides the following checks:

  • machine vibration;
  • wear of bearing raceways and rolling bodies;
  • quality of lubrication and bearing installation;
  • the level of bearing local defects (cracks, nicks, cavities);
  • bearing heating.

IDP-07 is intended for companies that operate electrical and other rotary machines with a rotation frequency from 300 to 6000 rpm.

Operating principle:

– when checking machine vibration, wear of raceways and rolling bodies, quality of lubrication and installation, level of bearing local defects, the indicator measures the values of the appropriate monitored parameters and indicates the assessment zones and the intervals within these zones, in which the measured values fall;
– when checking heating of the bearing, the indicator measures the bearing temperature (in a non-contact way using an infrared sensor), compares it with the maximum permissible one (100°C) and shows the result of this comparison.

Technical specifications:

1) testing parameters:
– when checking machine vibration vibration velocity (root mean square value)
– when checking wear of bearing raceways and rolling bodies, quality of lubrication and installation vibration acceleration (root mean square value)
– when checking level of bearing local defects peak impact acceleration (maximum value for series of impact pulses)
– when checking bearing heating temperature
2) dynamic ranges to be controlled:
– when checking machine vibration, dB 49
– when checking wear of bearing raceways and rolling bodies, quality of lubrication and installation, level of bearing local defects, dB 40
3) frequency ranges to be controlled, Hz:
– when checking machine vibration 5÷1000
– when checking wear of bearing raceways and rolling bodies 500÷1800
– when checking quality of lubrication and installation 2000÷10000
– when checking level of bearing local defects 25000÷31000
4) temperature range to be controlled, °С -10 … +120
5) indication LED and liquid-crystal one
