Instrument maintenance is difficult, you can only do the instrument well if you see it thoroughly!

Abstract: Instrument maintenance is difficult, only by seeing it thoroughly can you do a good job of the instrument! The information is provided to you by the excellent manufacturers of flowmeters and flowmeters. Instrumentation work is very complicated, hard and tiring, and complaining all over the sky. Why do instrument people always take the blame? Why are there so few people who are instrumental as leaders? Why is the instrument work never done, just a little, you didn't grasp the key point of the instrument work! The daily life of an instrument worker. More flowmeter manufacturers choose models and price quotations. You are welcome to inquire. The following are the difficulties of instrument maintenance. Article details. Instrumentation work is very complicated, hard and tiring, and complaining all over the sky. Why do instrument people always take the blame? Why are there so few people who are instrumental as leaders? Why is the instrument work never finished, just one point, you didn't grasp the key point of the instrument work! The daily work of the instrument worker is to drive, park and maintain the instrument, which reflects the idea of ​​total quality management and prevention first, and ensures the normal operation of the instrument. The daily work of the instrument is as follows: 1. Patrol inspection process Instrument workers generally have their own area of ​​responsibility for instrument maintenance. According to the distribution of instruments in the area of ​​responsibility, the inspection route is determined, and inspections are made at least once a day. The main contents of the patrol inspection: 1. Learn about the operation of the instrument from the technicians on duty. 2. Check the indication of the instrument, whether the record is normal, whether the indication of the primary instrument (transmitter) on site and the display instrument in the control room, whether the indicated value of the dcs operation station is consistent, and whether the output of the control loop and the valve position of the control valve are consistent. 3. Check whether the output of the 24v power supply is normal (the output voltage indicator light is often dark and there is an abnormality) whether the air source pressure reaches the required range (0.14MP, 0.35MP, etc.). Whether the power supply voltage and torque of the electric regulating valve are normal 4. Check the thermal insulation and heat tracing status of the instrument (mainly in winter), and measure the temperature by hand. 5. Check the damage and corrosion of the instrument body and connecting parts, including whether the flexible pipe connection is loose or damaged. 6. Check the leakage of instruments and process interfaces. 7. When the environment is poor, the outdoor instrument should add protective measures in time, check the protection status, and ensure that there is no damage or loss. 8. Check the alarm interlocking device to ensure that the device is in good condition. Regularly test the alarm interlocking function, and make test records 9. Check the integrity of the instrument. 2. Regular sewage discharge and refueling process With the great improvement of automation level, the number of pneumatic actuators has increased sharply. Therefore, daily maintenance should be performed on air source treatment equipment for regular sewage discharge and refueling. Common components of air source treatment equipment: 1. Filter, filter out the solid impurities and part of the moisture in the air source, and provide cleaner compressed air. (1) Manual drainage, when the water level reaches the lower level of the filter element, it must be drained; (2) Clean the filter element (soak, brush, blow back) or replace the filter element. Too much impurities can't breathe. 2. The pressure reducer reduces and stabilizes the pressure of the compressed air provided by the air source. When adjusting the pressure, it should be gradually and evenly adjusted to the required pressure value, not in one step. Trouble-free and maintenance-free. 3. The lubricator adds oil mist to the gas of the gas-using equipment to lubricate the equipment. Add oil and adjust the dripping speed. There is a twisting thing on the top to adjust the dripping speed. Fill the cup no more than eight points full. 4. Usual maintenance: If there is air leakage in the air source treatment equipment, it is abnormal, try to deal with the seal or replace it. 3. Regular lubrication and anti-corrosion process Regular lubrication and anti-corrosion are also a part of the daily maintenance of instrument workers, but they are often overlooked in specific work. The lubrication cycle should be determined on a case-by-case basis. The instruments and components that need to be regularly lubricated and anti-corrosion are as follows: 1. Pneumatic cam deflection valve, pneumatic ball valve, pneumatic butterfly valve, electric actuator rotating parts; 2. Protection box, door shaft of incubator, and fastening bolts of junction box. 3. Fix the bolts and nuts of transmitters, regulating valves, valve positioners, electrical converters in harsh environments to prevent threads from rusting and difficult to disassemble and assemble. 4. The rotating part of the feedback lever of the valve positioner in harsh environments. 5. Thermal resistance in harsh environments, bolts at the thermocouple junction box or the threaded part of the upper cover. 6. Flexible pipe and instrument connection part in harsh environment. 4. Antifreeze inspection process Checking the antifreeze measures of the instrument is one of the contents of the daily maintenance of the instrument. It is related to saving energy, preventing the instrument from freezing, and ensuring the normal operation of the instrument measurement system. It is an item that cannot be ignored in instrument maintenance. This work is seasonally strong, mainly to check whether the medium in the pressure guiding pipe of the gas tank liquid level transmitter is abnormal, and whether the insulation material has fallen off. Individual instruments need to be insulated and traced to check the traceability, and start and stop the tracer in time according to the weather conditions. Heat, it is necessary to prevent freezing and ensure the normal operation of the instrument. 5. Troubleshooting process Troubleshooting is an important part of the daily maintenance of the instrument. Troubleshooting should be quick and effective, serious and serious, without leaving hidden dangers. If there are problems that cannot be dealt with, they should be reported in time and dealt with in coordination. Troubleshooting requires active learning and experience accumulation by instrument personnel.Provide 'Notes on Driving and Parking' (attachment) for daily maintenance reference.
