Air end repairs include:
1. Diagnostics: disassembly, revision and assembly the air end.
2. Bearings replacement (we use bearings the best world bearings manufacturers).
3. Rotor surface recovery (if necessary).
4. Housing geometry recovery (if necessary).
5. Air end shaft seal kit replacement.
6. The optimal gap adjustment and rotor alignment, gaps regulation:
Gap and rotor alignment adjustment is released with using special tool, due to the highest efficiency of the air end and long lifetime of the unit is providing. The gaps adjustment are in certain ranges, which provides high efficiency.
If during compressor operation the gaps (for example, end gaps) will be adjust less than minimum value of the range, rotors heat, metal expands and it is a reason the rotor and housing contact.As rotation speed is high, shortly metal weld.
Then the screw unit can be just utilize. If the gaps are higher than maximum value of the range, efficiency decreases because of air-oil mixture leaks, as well as parameters of the cooling element and rotor lubricant are changed, that prevent to decrease the air end lifetime.
Our company repairs the air end of the following repaired air end.: Boge, Atlas Copco, Sullair, Kaeser, Gardner Denver, Hydrovane, Ingersoll Rand, Kaeser, etc. For the air end following types.
We provide warranty terms for repaired air end.
