In June 22nd, No. 4 urea production qualified urea, the Company No. 4 production system after a comprehensive overhaul, has returned to normal production.
The overhaul began in June 11th and continued for 12 days. The main tasks include changing positions, composite positions, replacing catalysts, desulfurization jobs, changing positions, cleaning fillers, production systems, equipment inspection, maintenance, etc. in No. 4. The maintenance time, heavy task, technical difficulties, so the production office, security, power and other departments attach great importance to the maintenance before the repeated demonstration maintenance program, strictly control the maintenance safety and maintenance of environmental protection, quality of maintenance, maintenance schedule, make maintenance smoothly, and ultimately the safety, quality, on-time completion.
During the overhaul process, the production system management staff and the majority of staff involved in the overhaul, and fully carry forward the "Ho source" can endure hardship, willing to sacrifice spirit. Some staff of 5 days and 5 nights did not go home, some staff of 6 days and 6 nights did not come home, some staff throughout the maintenance period did not go home, they trapped in the repair site near the temporary rest, then again dry, hungry to eat simple meals at the repair site, continuous fighting in overtime the maintenance line, regardless of personal gains and losses, for the repair schedule time.
In the course of inspection and maintenance, a batch of people who love and respect themselves, devote themselves to their work, and are amiable and respectable have emerged as the most beautiful scenic spots for the inspection and maintenance work. In the inspection site, every day can capture some wonderful moments, freeze some moving pictures, constantly by Hao source of work enthusiasm, fighting spirit moved. No. 4 desulfurization overhaul site, due to water cooling tower, the tower filled with steam, unusually hot, everyone into the tower, as long as a few minutes will sweat profusely, such a clear tower work difficulty and strength can be imagined. Physical quality is not very good master Han Wei, but willing to meet the difficulties, in such a hot tower unloading packing, continuous work for more than 4 hours. Colleagues have no admiration for the master, have for the maintenance of the people point praise, refueling.

Although the overhaul of the overall time is longer, but the machine company specific to each workshop overhaul time is quite tight, some maintenance must race against time, otherwise it will affect the system drive. For example, the joint workshop 2 meters post synthesis and post operation time control is particularly important. Machine lifting class in the joint workshop 2 meters post and post synthesis methanol methanation process of lifting, lifting class monitor Wang Huaiming led the lifting class, advance the development of the lifting scheme, every reasonable arrangement of lifting personnel, to ensure the maintenance of hoisting work orderly. To allow sufficient time for the subsequent repair work, lifting class Wang Huaiming, Zhang Heng led the field command, lifting personnel in hoisting site work all through the night.

It was the 24 hour continuous fighting of the lifting class, which gave ample time for the maintenance work.
Welding machine maintenance personnel from the date, whether in gas, compressed, or carbonization process, will work overtime into the night every day, morning and dragged his exhausted body, advance into the site maintenance work, and strive for the time for maintenance.
