(Summary description)In the second half of 2020, Hengli Petrochemical PTA gas tower circulating pump, number 512, has a total of four pumps, all of which are imported OH2 pumps, and the overflow material is titanium. The pump shaft was broken one after another, and the impeller was damaged along with it. The entire rotor of the fourth-line 512 was scrapped at the fastest 2 days, and the rest needed to be replaced with new impellers and shafts in more than a month, which has affected production. We have undertaken For the task of transforming the pump, the technical department redesigned the shaft and the impeller to increase the strength of the shaft and the impeller. The material of the impeller was changed to 2507, the impeller was changed to 17-7PH, and the original shaft seal was changed to a wrapped shaft structure. The medium is no longer in contact with the shaft, and the model of the mechanical seal remains unchanged. The first set of spare parts has been running stably for six months, the second set has also been running for two months, and the third set is now completed soon.
