REPAIR OF DIRECT CURRENT GENERATORS
Direct current generators are widely used in the metallurgical industry, transport, mining industries in installations, where a wide and smooth adjustment of the rotation speed is required.
The scope of repair of a direct current generator may include the following technological operations:
- Overhaul with production of new armature windings and magnetic system;
- Repair of the anchor with the manufacture of windings from new wire;
- Repair of the magnetic system with the manufacture of windings from new wire;
- Repair or manufacture of pole cores;
- Complete repair of the collector with the possibility of pouring or manufacturing and replacing it with a new one;
- Repair of the collector-brush unit;
- Repair of bearing units, shields and restoration of seats;
- Incoming quality control of bearings on the SVK-A machine;
- Repair and manufacture of shafts;
- Color defectoscopy of the shaft to detect signs of fatigue failure;
- Anchor balancing, including in its own bearings as part of the assembled machine;
- Vibrodiagnosis of an electric machine with frequency analysis of the vibration spectrum;
- Diagnostics and testing of electric machines;
- Thermal imaging control of windings and bearing units of an electric machine during acceptance tests.
