Gea Grasso ice machine maintenance
Thread Content
GEA Grasso ice machine overhaul. Stop the machine, disassemble the machine head and transport it to the maintenance workshop. The compressor was disassembled, the rotor end face and exhaust end face of the GEA screw compressor were severely worn, and the bearing bush was severely worn. Replace the exhaust end face, repair the rotor end face, and replace the bearing bush, bearing, shaft seal, and complete set of seals. Adjust the gap, assemble, maintain and inspect, spray paint, transport to the unit site for hoisting, install couplings, counterweights, and start up and debug. The equipment is running normally, all parameters are stable, and the process operating temperature has been reached.
Could you please tell me the names of some parts?
The third picture is a worn bearing. The fourth picture is a bad bearing. The fifth picture is a new bearing. The sixth picture is a worn screw end. The seventh picture is a screw end repair. The eighth picture is a worn exhaust end insert. The ninth picture is a new exhaust end insert. The tenth picture is a worn balanced piston sleeve. The eleventh picture is a new balanced piston sleeve.
Please tell me how to repair the end face of the ice machine rotor. Can you explain it in detail?
