The importance of emergency maintenance plans for equipment

Thread Content

I’m not sure if it’s possible to post an article on plans for economical equipment maintenance in this section; the content will be quite general. I hope my colleagues can offer some guidance! Production equipment refers to the machinery and devices that industrial enterprises use to directly participate in the production process or to serve production directly, mainly including mechanical, power, and transmission equipment. Production equipment is the most important material guarantee for large-scale social production. Only by ensuring the safe and continuous operation of a company’s production equipment can it continue to produce products, generate profits, and sustain the development of industrial enterprises. However, production equipment is affected by various factors such as the level of operation, its operating environment, maintenance capabilities, and natural disasters, which often lead to various issues such as wear and tear, corrosion, and leaks. Therefore, systematic and thorough daily maintenance as well as regular inspections are necessary for such equipment. If the equipment is not managed properly, it may result in forced shutdowns for repairs in mild cases, or in catastrophic consequences such as explosions, releases of toxic substances, casualties, and environmental pollution in severe cases. Listing the economic losses incurred by certain industries and companies as a result of a one-day shutdown serves as a warning to equipment managers: A chemical plant in Henan lost 3 million yuan in revenue due to a one-day shutdown for emergency repairs, which accounted for nearly 7% of its annual profits ； At Wuhan Iron and Steel Group’s hot strip rolling plant, a one-day shutdown results in a loss of 10,000 tons of sheet metal in production, amounting to a loss of 20 million yuan in revenue ； Anan Steel’s semi-continuous hot-rolling sheet plant loses 1 million yuan in profit per day of shutdown ； Yanshan Petrochemical Company in Beijing suspended operations of its tetraene equipment for one day, incurring losses of over 4 million yuan ； Honda’s vehicle manufacturing plant in China generates 200 million yuan in daily output; a one-day shutdown results in a loss of 200 million yuan ； A production line in a cement plant with a daily output of 5,000 tons incurs a direct economic loss of 2 million yuan per day of downtime ； A paper manufacturing company in Shandong produces 500 tons of newsprint per day; at a cost of 5,000 yuan per ton, a one-day shutdown results in a loss of 2.5 million yuan ； The large-scale fertilizer production plant of Qilu Petrochemical suffered a loss of 560,000 yuan after shutting down for one day due to a leak in the main heat exchanger ； A Sinopec subsidiary that produces 300,000 tons of ethylene per year loses 7.5 million yuan per day of shutdown ； ……The aforementioned staggering economic losses are just one aspect of the heavy damages incurred when businesses are forced to shut down. In the event of more severe safety accidents such as explosions or leaks of toxic substances, the losses can be immeasurable. For example, in 1984, at the Union Carbide plant in Bhopal, the capital of Madhya Pradesh in India, a failure of valves led to the release of highly toxic substances, resulting in 3,000 deaths, 50,000 people losing their eyesight, and 200,000 people suffering health problems. In 1986, a serious failure occurred at Reactor No. 2 of the Chernobyl nuclear power plant in the Soviet Union, resulting in significant economic losses of 8 billion rubles, severe environmental pollution, and a social disaster. Therefore, equipment safety incidents such as forced shutdowns have become a cancer hindering the development of manufacturing enterprises. Regarding these emergency equipment issues, some cannot be predicted through prior testing or online monitoring; they occur without any obvious signs or a gradual progression, while others are caused by negligence in equipment management and maintenance or operational errors. Regardless of the cause, it is necessary to employ the most appropriate repair measures and solutions as quickly as possible once a failure occurs, in order to restore the normal operation of the equipment. Such emergency response mechanisms are usually referred to as “equipment emergency repair plans”. An emergency maintenance plan for equipment is a contingency plan prepared in advance to address the types and severity of potential or possible production safety accidents. The emergency maintenance plan for equipment is based on the principles of unified leadership, hierarchical responsibility, rapid response, decisive decision-making, and mutual cooperation. It aims to ensure proper emergency preparedness, enable effective handling of emergencies, and reduce casualties and property losses. In the process of cooperation between Meijiahua and manufacturing enterprises, it was found that although some of these enterprises have established emergency plans for equipment management, when faced with serious equipment emergencies, they fail to conduct regular drills or reviews, which leads to chaos when such problems arise. Moreover, a lack of appropriate repair methods and techniques significantly hinders the rapid resolution of equipment issues. The shortcomings in the implementation of such plans, along with the lack of maintenance skills, are the biggest obstacles to the effectiveness of emergency maintenance procedures for equipment, and they are also the most significant factors contributing to increased losses resulting from equipment safety incidents. As the saying goes: If one wants to do his work well, he must first sharpen his tools. If a craftsman wants to make good tools, he must first master the proper methods. Of course, the emergency maintenance plan for equipment is merely a means to minimize the losses caused by accidents; it cannot serve as a ‘lifesaver’ for dealing with all equipment problems. To improve the level of equipment management, it is necessary to carry out regular equipment maintenance and ensure orderly management.
