The second electrolysis plant equipment early-warning maintenance mechanism reduces the failure rate

Beginning in 2014, the second electrolysis plant implemented an early warning maintenance mechanism for equipment in response to random, empirical and disorderly maintenance that caused the increase in equipment repair rates and repeated failures in the current equipment maintenance process. Failure rate of critical equipment.

The equipment inspection department of the plant arranges technicians to check the abnormal items of equipment every week, analyze the equipment with weakened performance, issue early warning maintenance notices to the equipment or parts that may be faulty or about to fail, and require relevant personnel to give early warning Overhaul and maintenance, thereby eliminating equipment failures in the bud. At the same time, in order to ensure the quality of the early warning maintenance mechanism, the plant’s equipment inspection department included early warning inspections into the scope of professional inspection re-inspections, and conducted re-inspections on schedule. At the same time, the situation after the early warning was tracked and recorded to effectively ensure the effect of early-warning maintenance. As of the end of June, the plant's equipment inspection department issued a total of 6 equipment overhaul and maintenance early warning notices, which greatly reduced the failure rate of key equipment.

From January to May, the plant’s key equipment intact rate increased by 0.21% compared with the same period in 2013. The number of major failures of multi-function cranes decreased by an average of 5 times compared with that of 2013. No major failures occurred in key equipment such as the station package, busbar hoist, and trough controller.
