Inspection items for equipment: 1. General issues of \"leaking, escaping, dripping, and seeping\"； 2. Check whether the basic instrument parameters of the equipment are normal, such as pressure, current, temperature, flow rate, vibration, oil level, etc ； 3. Inspection of the connection parts of critical equipment: such as the coupling of the reducer, the noise emitted by the reducer, the location of the lubricating oil and its condition, as well as whether the foot bolts of the reducer are loose ； 4. Are there any cases of non-compliant operations? ； 5. Understanding of the equipment handover process. Regarding the specific inspection items for moving and stationary equipment, for moving equipment: 1. Use inspection methods such as looking, listening, and touching ； 2. Visual inspection: Check its operating status and the readings on the relevant indicator instruments (pressure, temperature, oil level, current, etc.) ； 3. Second listening: Listen to the sound it makes during operation to check for any abnormal noises ； 4. Three-touch check: Feel whether there are any abnormal vibrations in the operation of the device; this can be done with the help of relevant measuring instruments such as vibration meters. For static equipment: 1. Mainly check its appearance ； 2. Integrity of connection components ； 3. Operating status of relevant instruments (field instruments) ； 4. Issues such as running, leaking, dripping, and seeping. Differences in the inspection of stationary and moving equipment: Stationary equipment: Simply put, it involves checking whether there are any differences from normal operation; an even minor anomaly can indicate a potential hazard. Movable equipment: The main thing is to listen for any differences in the sound compared to normal conditions. After spending time at the post, it becomes easy to do this, as one becomes very familiar with the sound of the equipment operating properly over time; if there’s a problem with its operation, the sound will definitely be different. It is also necessary to check the lubricant level and the temperatures at the key control points of the bearings (it is possible to verify this by staying in regular contact with the control room). With the rapid development of the market economy, enterprises face increasing competitive and cost pressures; minimizing production costs and maximizing economic efficiency have thus become the goals that companies strive to achieve. Against this backdrop, the so-called zero-failure equipment management emerged. Zero-failure equipment management 1. The concept of zero-failure equipment: Simply put, zero-failure equipment means using appropriate maintenance methods to inspect the equipment before failures occur, eliminating potential faults and defects so that the equipment remains in good working condition at all times. Regarding the understanding of the zero-failure concept, it should be noted that: (1) zero failure does not mean that equipment will never experience failures; rather, it involves making every effort to prevent failures and maintain stable production operations. (2) Zero failures is a systematic concept. It is not difficult for an individual piece of equipment to achieve zero failures, but minimizing the impact of its downtime for maintenance on production is a complex process that requires taking into account the overall condition of the production equipment as well as the overall economic efficiency of the production system. (3) The core of the zero-failure concept is to eliminate planned downtime and emergency repairs. The losses caused by unplanned shutdowns and emergency repairs are enormous, and the consequences can sometimes be very severe. 2. Causes of equipment failures and failure modes There are many reasons for equipment failures, as well as various classification methods; the following discusses them briefly from a few perspectives only. ①From the perspective of the device’s service life, device failures can be divided into two categories: congenital failures – those caused by inherent defects in the device resulting from improper design or manufacturing. Functional failures – failures caused by factors such as installation and maintenance, operation, and natural deterioration of the equipment. ②Strictly speaking, human factors are involved in equipment failures; inherent defects in the equipment themselves can also be considered human factor-related failures. These defects are influenced not only by the skill and sense of responsibility of the designers and manufacturers but also by the stage of development of science and technology. After the equipment is in operation, careful operation and daily maintenance become the most important human factors. As the ancients said, “Disasters often lie hidden in subtleties, emerging where people are careless.” ③Equipment failure modes are primarily reflected in the bathtub curve. Different equipment has distinct failure modes; therefore, in practice it is necessary to carefully study the specific failure modes and characteristics of a particular piece of equipment, and to adopt appropriate maintenance, care, and repair methods accordingly. For early-stage failures, it is necessary to conduct in-depth studies of various failure symptoms, investigate the causes of equipment accidents, and formulate corresponding countermeasures and measures. During the equipment’s wear period, it is necessary to avoid unexpected failures; TPM (Total Productive Maintenance) should be strengthened, various monitoring techniques should be widely applied to understand the operating trends of the equipment, and management of equipment degradation tendencies should be carried out. 3. Analysis of maintenance methods for zero-failure equipment management: For equipment used in production processes, reactive maintenance is not advisable. Therefore, the maintenance methods under zero-failure management include the following aspects: preventive maintenance (also known as regular maintenance), predictive maintenance, and proactive maintenance (also known as corrective maintenance). The above three maintenance methods constitute the basic framework of Reliability-Centered Maintenance (RCM), and a comparative analysis is shown in Table 1. In short, the maintenance approach of zero-failure management is to address the questions of \"when to repair and how to repair.\" 4. Discussion on approaches to achieving zero equipment failures. Equipment failure management is a complex systematic engineering task, and its management process is comprehensive. It requires participation from everyone (from supervisors to operators and maintenance staff) and involvement throughout the entire process (all stages of equipment management). The process of achieving zero-failure equipment management is also a process of improving corporate culture building. The approaches to achieving zero equipment failures are discussed from the following aspects. ①Reduce the probability of failures by minimizing equipment defects; equipment defects cause equipment failures, and those failures lead to accidents. ““A dike a thousand miles long can be ruined by an ant hole”; achieving zero equipment failures starts with reducing equipment defects. The basic activities for reducing equipment defects are: 5S activities: Seiri, Seiton, Seiso, Seiketsu, and Shitsuke ； 6S activities: Sorting, Straightening, Cleaning, Sanitizing, Standardization, Safety ； The 8-character principle: Sort, straighten, lubricate, adjust. ②The process of using standardization to reduce defects is an ongoing one; to achieve an ideal state, standardized work documents must be established. Standardization is the foundation of the aforementioned activities and the essence of all management efforts. The standardization process is one that progresses from small to large, from simple to complex; it is not possible to achieve perfection in just one step, and standardization documents need to be continuously revised and improved. ③Implementing TPM and RCM – in fact, the aforementioned basic activities and standardization efforts aimed at reducing defects are precisely the essence of TPM, which is characterized above all by full employee participation. RCM, see Table 1. It starts with preventive maintenance, scheduling planned inspections based on the results of equipment condition monitoring in order to achieve the highest equipment utilization rate and the lowest maintenance costs. ④Strengthening equipment condition monitoring and fault diagnosis is an effective way to avoid equipment failures and unexpected accidents. At the current stage, for Zhongtian Steel Company, equipment condition monitoring and fault diagnosis should focus on the following: (1) Continuously improve the two-level monitoring system of departmental inspections and shift inspections, implement quantitative inspections, and truly extend condition monitoring and fault diagnosis technologies to shift teams and front-line staff – this is key to achieving zero equipment failures. (2) Develop standardized operation documents for equipment condition monitoring and simple fault diagnosis. (3) Strengthen the networked online monitoring and diagnosis of key equipment, vigorously promote the application of such networked monitoring technologies, and detect potential issues with equipment at an early stage to prevent serious equipment failures. (4) Attach importance to the training of diagnostic technicians. ⑤Create a good working environment and show comprehensive care for employees. Looking at monthly equipment failures, those caused by \"improper operation\" and \"inadequate maintenance\" account for one-third of such failures, or even more. Why? In addition to the aforementioned basic activities and standardized operations not being carried out properly, it is also closely related to the enthusiasm and initiative of the workforce. As the management levels of the company, they should carefully study this issue, starting from paying attention to all aspects of the employees’ work and life. Conclusion: This article discusses the concept of zero-failure equipment, the causes of equipment failures, and the equipment maintenance methods used in zero-failure management, with a focus on the specific approaches to implementing zero-failure management. To implement zero-failure management, it is essential to establish entirely new concepts and ways of thinking ； There is no unified model for implementing zero-failure management; it should be continuously discussed and refined through practice ； Implementing zero-failure management will undoubtedly have a profound and lasting impact on all aspects of basic equipment management.
