1. CAPITAL REPAIR OF TAMPING UNITS:
| |
- FAULTS:
A. Broken and worn out bearings. Inadmissible axial clearances. Seals ring leaks.
B. Broken gear-wheels. Advanced wear and noise in the gear-wheels. Availability of cementation flakes and borings in the oil.
C. Превъртане и задиране на шийки на основни валове.
D. Wear of shaft seal rings.
E. Other problems: worn out axes, bushes, bearing housing, etc.
- REPAIR WORK :
A. A tamping units overhaul. Changing of worn out bearings and nodes. Changing of spacer and seal rings.
B. Dismounting, mounting of gear-wheels.
C. Journal recovery. Manufacturing new shafts.
D. Manufacturing of new spacer rings – cementation and grinding.
E. Recovery of bearing housing. Manufacturing of new bushes, guides, etc.

2. REINFORCEMENT OF CONNECTING WELDS ON BEAMS, FRAMES AND BODIES:
| |
- FAULTS:
As a result of excessive loading and great vibration cracks may occur in the connecting seams on beams, chassis, etc.
- REPAIR WORK OPTIONS :
Flaw detection test of seams, filing bright and welding of the cracks ,welding of strengthening claps using high strength “Behler” electrodes.

3. ELIMINATION OF CRACKS ON HIGH PRESSURE PIPELINES (HYDRAULICS AND PNEUMATICS)
:
| |
- FAULTS:
Occurrence of cracks.
- REPAIR WORK OPTIONS :
Fusion weld penetration of cracks, surface welding of a second layer using high-strength electrodes, cladding with a special micro-capillary solder, a Castolin produce. 100% flaw detection and water test at maximum work pressure.

4. REPAIR AND ELIMINATION OF CRACKS AND DEFORMATIONS ON STEEL AND PIG IRON CASINGS AND COVERS OF HYDRO CYLINDERS AND OTHER NODES:
| |
- FAULTS:
Occurrence of cracks in the connecting seams, eye ring rupture and deformation. Broken fixing axes of hydro-cylinders, etc.
- REPAIR WORK OPTIONS :
Elimination of cracks in the connecting seams; replacement of deformed and ruptured hydro-cylinder main eye rings with new ones, alignment, welding and strengthening of the latter; welding and strengthening of the deformed or ruptured pig iron eye rings at the fore end of the cylinder for clamping the valve to the double sleeper. Making of new high strength steel fixing axes, thermo-treatment, grinding and polishing of the latter.
