Steam turbine coupling overhaul sidelights

Steam turbine coupling overhaul sidelights - 2018 07 - 26 ( Anhui huai chemical group co. , LTD. ) On the afternoon of March 2, 2017, after the condition maintenance, maintenance department inspection team, and all department, mechanism for plant, equipment etc various elite gathered ammonia plant of air separation plant, steam turbine shaft coupling overhaul key maintenance projects underway, quiet immediately send hot picture of the plant. Air compressor, turbine be called air separation equipment of a complete set of the heart, so the overhaul quality, precision, such as demanding, not tolerate the slightest careless. Responsible for the maintenance of inspection team who has dealt with this huge equipment to play many times, but still did not dare to have any luck to snub. Maintenance staff, in conjunction with the driving carefully will air compressor and turbine coupling cover lifting. Demolition of coupling, the maintenance staff found inside the coupling with oil, if not handled, will drive a car after a big security risk. Coupling has no oil discharge hole, how to get the oil out? Once everyone is discussed, decided to coupling oil unloading drill four 4 mm hole. So, does not damage equipment and the oil is discharged. Because the space is limited, can only use drill hole, took the task of immediate action mechanism for factory employees. Under normal circumstances, the four drill up time soon. But this time is in the material quite hard equipment, difficulty cans be imagined! Only heard from until ten o 'clock in the evening, the plant pistol electric drill and replace the 'make' voice the voice of the broken bit. 3 in the morning, in the coupling oil after release, all take part in the management of the maintenance of equipment and technical personnel carefully check, questionable, temporary decided to overhaul support and oil seal, air compressor drive on the use of maintenance, eliminate all possible existence of hidden dangers. A seemingly simple task, it was hard to do. The removal of the air compressor equipment repair precision every screws should be marked, must be accurate positioning, otherwise can't back pack. Like ahead of division of labor, maintenance staff into several groups on its own. Drive end support tile need special tools to remove, can only be improvised. Inspection team who Gao Wei, zhang didn't say two words, field measurement, immediately cooperate with welding, with 30 mm thickness of steel plate made a span of 810 mm, 260 mm lift shaft. Lift shaft device at the same time, the synthetic ammonia plant equipment member WengJing sail, the cleaning, steam turbine and nitrogen compressor coupling bolt fastening, create favorable conditions for the safe operation of the equipment. All work is as nervous but can't see. In two days and nights, steam turbine coupling overhaul and masses together or only a few hours of eye, their spirit and energy into the maintenance, for equipment can early some back and high quality work, as long as the equipment is normal, again painstakingly again tired all values.
