For a long time, high-voltage devices have to be long-term operation of the instrument in the harsh process conditions of ultra-high temperature, ultra-high pressure, chain point and more, to prevent the instrument from unplanned parking is a severe test. As of the end of December, the company two Since the beginning of this year, No. 1 high-voltage device runs smoothly for over 62 days and No. 2 high-voltage device operates for a long period of more than 75 days. Both of these devices have broken the need for similar devices in China to be stopped every month Bottleneck.At present, the operation of two sets of high-pressure device smooth rate of more than 98%.
Earlier this year, Maoming Petrochemical Branch of the instrument shop put forward 'to eliminate the cause of instrumentation unplanned shutdown benefits', the establishment of high pressure instrumentation research team, a comprehensive statistics of the two sets of high-voltage devices in the history of parking events, through the study to effectively develop a precautionary approach Measures. They also actively cooperate closely with the process plant, provides important instrument inspection items, cycles, standards and other content, to achieve standardized instrument maintenance.
This year, the instrumentation workshop to step up inspection efforts, through preventive inspection, detected 1 # high pressure reactor bypass valve HV142 junction box damp, silo three-way valve F4208-1 leakage of key valves and other hidden dangers of more than 40 instruments, And in time for rectification; 2 # high voltage device for the pressure pipe wear and other issues, the replacement of 2 # 21 high pressure unit import and export buffer tank pressure transmitter pressure pipe, effectively prevent the pressure pipe is worn, wear through the situation. They also continue to carry out technical research, completed a # 1 # 220VAC instrumentation load redundant power conversion project; will be 2 # high pressure device masterbatch extruder barrel integrated temperature transmitter to split installation, to solve the temperature The instrument is easily subject to high temperature scald and damp damage; the 1 # high-pressure primary frame vibration switch is transformed into three analog measurements, the chain realized three take two transformation, to avoid the problem of malfunction.
In addition, they also actively carried out "hidden investigation" and "five small" labor competitions in order to stop unplanned parking due to the instrumental reasons, ensure long-term operation of equipment and win-win benefits, and greatly motivate employees to maintain meticulously, learn skills and reduce cost and increase efficiency Of the enthusiasm for the two high-pressure device long-term operation escort.
