Reactor commissioning and acceptance

Thread Content

Preparatory work 1. Thoroughly review the quality of the maintenance. 2. Thoroughly clean the maintenance site ； Carefully check the reactor for any remaining items, and once it is confirmed that nothing is left, seal off access ports, manholes, etc. 3. Remove the blind flanges as required by the process, and open or close the valves connected to the reactor vessel. 4. Apply lubricant to the rotating parts. 5. Manual cranking should be smooth, with no audible collisions from the internal components. Testing 1. A dedicated person is responsible for supplying power. 2. First, perform a no-load jog to confirm that the operating direction is correct and there are no abnormalities, before starting the actual no-load operation. 3. Run without load for one hour; the following should be achieved: a. Good lubrication in all areas ； b. The mechanical transmission performance is normal (including noise, vibration, temperature, etc.) ； c. The current remains stable and does not exceed the rated value during no-load operation ； d. The radial runout at the seal area of the stirring shaft meets the requirements. 4. After the no-load test is successful, run the system with water for four to eight hours, and then conduct a test with material fed in for at least one reaction cycle. The following requirements must be met: a. Good sealing, in compliance with the leak-free standard ； b. The instrument is sensitive and reliable ； c. The temperature of the rolling bearings shall not exceed 70°C. The temperature of the sliding bearing shall not exceed 65℃ ； d. The motor and reducer operate smoothly with normal temperatures ； e. The pipelines, foundations, and supports show no significant vibration. Acceptance: 1. After the trial run is successful, a comprehensive analysis is conducted of the maintenance work carried out as well as all the data collected, in order to draw lessons learned, identify problems, and propose improvements for future maintenance tasks. 2. Carry out the acceptance procedures and hand over to production. The main technical documents for acceptance should include: a. Maintenance records ； b. Records of pressure resistance and airtightness tests ； c. Non-destructive testing reports for major components ； d. Inspection records of safety accessories.
