What should be done with instruments during overhaul? Does anyone's company have more complete regulations? In fact, instruments should do more work in this area to improve their status in the company.
Pressure gauge, transmitter verification. Maintenance of regulating valves, etc.
Conduct inspections and calibrations on all instruments, replace those that need to be replaced, and repair those that need to be repaired, to ensure more efficient production after overhaul.
⒈Pressure gauge, transmitter verification； ⒉Regulating valve maintenance ； ⒊Cooperate with fitters to dismantle temperature, vibration, displacement and other instrument measuring equipment ； ⒋DCS replacement ； ⒌Treatment process presents problematic instrument valves ； ⒍Replace components that have expired. ⒎Calibrate interlocking and compare indoor and outdoor signals of instruments ； ⒏Installation and adjustment of new equipment and instruments. Wait, live a lot.
Do you have any details? There is a lot mentioned above, but it is difficult for me to implement here: 1. I check the pressure gauge regularly, there is no need to wait for overhaul. I don’t have any verification equipment or qualifications for the transmitter. 2. I only repaired the faulty regulating valve, and cleaned the normal one. 3. Replace components that have expired. In my case, they usually expire when they are broken. If I just replace it if it's not broken, the leadership won't be right, and I won't be able to convince them. So, do you have the details of your company's overhaul, such as the form for instrument overhaul, etc.
1. Inspect instruments that cannot be repaired online during the normal production process. 2. Inspect and verify the more important measurement points in the production process and instruments suspected of having measurement errors. 3. Deal with leaks and leaks during the production process. 4. Replace components or the entire instrument. 5. Clean DCS dust and inspect related cards and procedures. 6. Make relevant technical optimization and transformation of on-site instruments.
Instrument calibration is one aspect. During the shutdown, some items that cannot be processed, such as flow meter regulating valves, etc., and those that cannot be repaired due to internal leakage of the valve must be completely repaired during the shutdown. It also includes the technical transformation of some instruments.
Instruments mainly need to be replaced if they are not working, and they must be fully designed during installation.
