Chemical equipment can be divided into major categories: mechanical equipment, instrumentation equipment and electrical equipment. Mechanical equipment is divided into dynamic equipment and static equipment according to major categories. Assuming that you are asking about mechanical equipment, try to answer the following: For moving equipment, pay attention to monitoring the vibration, noise, lubrication status, and sealing of the operation during operation. The temperature and pressure of the system and fluid, especially the control of lubrication management, are particularly critical. If the control is not good, the rotating equipment will be overhauled or even scrapped. On the other hand, seal failure is a common failure mode in daily maintenance management. , It has a greater impact on process safety, which can be managed and continuously improved as daily maintenance work; for static equipment in operation, pay attention to monitoring the temperature, pressure, flow, liquid level, PH value, and Cl ion of the medium , S ions and other corrosive elements to avoid accidental failure modes such as corrosion, erosion, and stress fatigue. The specific control plan for equipment maintenance and management needs to be based on the specific information and restriction conditions of the design, manufacturing, and operation of the equipment, and system analysis based on RCM and RBI methodology, so as to adopt a targeted control plan based on specific and clear failure modes To ensure process safety and equipment reliability up to standard.
