Qilu Petrochemical builds a 5S management model during maintenance

News from Sinopec News Network, "In this maintenance, we will fully implement 5S management standards, starting with civilized construction and green maintenance, and at the same time improving the quality of maintenance to a higher level.

Source control: details determine success or failure

At present, the regional maintenance of the second fertilizer plant of Qilu Petrochemical has entered the final stage.

The management of the overhaul site is closely related to the quality of overhaul.

"The maintenance of the unit is an operation.

The ammonia ice machine is the key unit for this overhaul.

Three-level confirmation: the slightest difference, the loss of thousands of miles

During the overhaul, they divided the key nodes into three levels: ABC.

"In order to achieve the goal of quality control over maintenance, we start from the basics, starting from bit by bit, what do we do every day? What are the processes? What key node data are recorded? We also need to take pictures and leave image data.

　　They pay special attention to the adjustment of equipment such as bearing bushes and thrust gaps.

　　"When adjusting the bearing gap, it is possible to adjust for two or three days after a difference of one'pass'.

　　Strict assessment: the effect is gradually showing

　　In the early stage of maintenance, the operation and maintenance center strengthened the training and education of inspection personnel, established the concept of "doing standard work and civilized work", and cultivated the habit of civilized maintenance during the maintenance.

　　During the overhaul process, in order to ensure the implementation of the "5S" standardized management requirements at the major overhaul site, each professional department conducts professional supervision on the overhaul site, promotes the standardization of on-site civilized construction behavior, and intensifies the rectification of problems.

　　At the maintenance site of important units such as ammonia ice machine, agitator, high-pressure coal slurry pump, disassembled spare parts, regional division, label storage management are clear at a glance, and the standardization of "three never see the sky", "three never land", and "one line" is strictly implemented.

　　In the gap adjustment tutorial, if the upper and lower interval exceeds one "track", the error will exceed the standard and even shorten the equipment operation cycle.

　　At present, the regional maintenance of the Second Chemical Fertilizer Plant has entered the start-up procedure one after another.
