Key differences in inspection priorities for moving equipment and stationary equipment

Thread Content

1. General problems of “leaks, spills, drips, and escapes”； 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 couplings of the reducer, the noise produced 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 violations of procedures? ； 5. Understanding of equipment shift handovers. II. 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 condition and the readings on the relevant gauges (pressure, temperature, oil level, current, etc.) ； 3. Second listening: Listen to the operating sound; check for any abnormal noises ； 4. Three touches: Check whether the vibrations generated during the operation of the device are abnormal; this can be done in conjunction with relevant measuring instruments, etc. (vibration meters). For static equipment: 1. Mainly inspect its appearance ； 2. Integrity of connecting components ； 3. Operation status of related instruments (field primary meters) ； 4. Conditions such as running, steaming, dripping, and leaking. III. Differences between inspections of static and dynamic equipment
Static equipment: Simply put, it involves checking for anything that seems different from the norm; even a very minor anomaly might reveal a potential safety hazard. For rotating equipment, the main thing is to listen for any differences in the sound compared to normal conditions. Those who have worked at their posts for a long time know that this is quite easy to do, as they become very familiar with the sounds produced by equipment operating normally. Any deviation from these normal sounds surely indicates a problem with its operation. Also, check the lubricating oil level, and monitor the temperatures at several key control points of the bearings (it’s advisable to frequently contact the central control room for confirmation).
