Yizheng Chemical Fibre Polyester Center successfully implemented non-stop replacement equipment

Recently, Yihua Polyester Center has successfully replaced the thirteen-unit 24R01 buoyancy level gauge online to remove a blocker for safe and stable production.

In the polyester center three device thirteen unit 24R01 reactor buoy level gauge indicates abnormality, causing the level gauge to frequently jump to full scale. After being diagnosed by the process and instrument personnel, it is initially determined that the buoy is caught by the charcoal and needs to be opened to clear the charcoal. Processing. In order to ensure the long-term stable operation of the device and the quality of the product is not affected, the polyester center decided to process the buoyancy level gauge online.

To ensure the smooth progress of the repairs, the center has carefully prepared. The engineers and technicians pre-designed the maintenance plan. The instrument personnel prepared a float level gauge and calibrated it for replacement. On the morning of April 28th, the production process, instrumentation personnel, and inspection and maintenance personnel were all in place. The leaders of the polyester center also came. The technicians processed the process according to the maintenance plan and worked closely with the maintenance personnel to safely and properly clean the coke in the shortest time and replace the float level gauge. At the same time, the production stability and product quality were ensured. At the same time of replacing the buoyancy level gauge, it also solved the plugging of the vacuum pressure-inducing tube and replaced the nitrogen-filled ball valve online, ensuring the long-term stable operation of the production. The instrument personnel disassembled the torsion pipe bolts, hooked the buoys with a wire, and removed the coke-removing material. The maintenance personnel disassembled, repaired, and loaded the 24R01 gas-phase outlet nitrogen valve in one go.
