Bao filter oil filter machine cooperates with China Railway 15th Bureau to “protect and escort” the hydraulic system of Chengdu

Now Chengdu is just a stage of rapid development. In particular, the three-ring workers are taking time to repair the subway, so that everyone's travel is much more convenient. Generally, this kind of project will use the oil filter. Chengdu Metro Line 5 is the successor. In addition to Metro Line 1 which has been opened in Chengdu, another subway hub runs through Chengdu to the north and south, with a total length of 49km. The first phase of the project starts from 15 years and is expected to be fully operational in 19 years.

The fifth tender of the first phase of the project was won by the China Railway 15th Bureau. The 15th Bureau No. 2 shield machine was in use due to the water in the lubrication system heat exchanger, which caused the hydraulic oil to be emulsified seriously. It cost more than 400,000 yuan to replace all the hydraulic oil. However, the new hydraulic oil worked for 2 days and there was a serious emulsification phenomenon. Due to insufficient lubrication, the shield machine No. 3 high-pressure oil pump was damaged, the maintenance cost was over 1 million, and due to the hydraulic system problem, it had to be shut down and rectified, facing the owner. Strong pressure on construction schedule requirements

After on-site communication with Bao filter source engineers, after 15 collective decisions of the project, it was decided to use the TYA series vacuum coalescing separation oil filter produced by Bao filter source for continuous filtration. On the second day of continuous filtration, the oil product was obviously improved. The shield system was restarted. After a week of filtration, the entire hydraulic oil emulsification problem was completely controlled, the oil recovered from the milky white to yellow, and the working kinetic energy of the entire shield hydraulic system was completely released.
