What does factory production equipment inspection rely on?

Meticulous.

Inspection is not only patrolling, but also inspecting.

Inspection is not just a matter of going around in circles, checking, hanging a sign, and doing business. The key is to check for hidden dangers and eliminate risks. The equipment is large, the process is complex, pipelines are scattered all over the place, the equipment is running at high speed, leaks and leaks occur from time to time, and various safety hazards arise one after another. Whether it is the focus of daily inspections or pipelines that are not often touched, inspections must be comprehensive and cannot be careless. Check carefully, compare before and after, understand the dynamics, and eliminate hidden dangers in time.

Especially on the first working day after the holiday, you have to look at the precautions for inspection of factory production equipment and equipment. Come and do the inspection with Yunweibao's production equipment full life cycle management experts!

1. What is the purpose of inspection?

    It can detect abnormal conditions of equipment in time to avoid system shutdown and accidents. In actual production, it varies depending on the industry and process, but the general requirement should be: being able to detect abnormal conditions on the production site and handle them simply. This includes equipment, pipelines, instruments, control points, etc. The purpose is to ensure the stable operation of production equipment.

2. Qualities that inspection personnel must possess

    It is not easy to achieve four understandings and three skills.

First, you must undergo systematic theoretical training, and then you must have relatively rich on-site experience. Especially for those who transfer (those with poor foundation), it is even more difficult! It is a gradual process for inspection personnel to become familiar with and master the system correlation, sensitivity to changes in process indicators, and equipment operating conditions, which is crucial for future inspection work.

3. Responsibilities of inspection personnel

The degree of automation is getting higher and higher, especially in continuous production lines. During normal production, the site can basically be unattended, but when starting and stopping equipment or handling abnormal situations, manpower is needed. Therefore, most units still set up on-site inspections, and some have unwritten regulations that require two inspection personnel. Therefore, to a certain extent, the phenomenon of "bell ringing" in on-site inspections has also been caused.

4. Inspection requirements

1. Establish a patrol inspection system for production equipment, and improve and establish corresponding records. It is recommended that equipment managers choose a new generation of information technology and use cloud maintenance factory maintenance SaaS services to empower factory inspection personnel and realize production equipment Paperless inspection and equipment digital resume;

2. During the inspection process, the personnel on duty should do the five things in place, namely "listen, touch, check, see and smell";

3. During the inspection process, if any leaks, leaks, or leaks are found in pipelines, equipment, valves, and flanges, corresponding solutions must be provided and records must be kept;

4. During the equipment inspection process, inspection personnel strictly follow safety regulations, use a high sense of responsibility and use the inspection method of "look, smell, ask, and feel" to discover and eliminate potential accident risks in a timely manner.

    The occurrence of any equipment accident has a process from quantitative change to qualitative change, and it must go through three stages: from the normal operation of the equipment to the emergence of hidden dangers and then to the occurrence of the accident. The gradual change process from normal equipment to potential accidents is a gathering process of quantitative changes. In this process, the quantitative changes of equipment are manifested by specific characteristics. Therefore, it is strongly recommended to use the cloud maintenance Mbox equipment auscultation service software and hardware solution for high-value production equipment in the factory to achieve real-time monitoring of equipment health and predictive maintenance services.

    For example, when a high-pressure pipeline bursts, there must be a process of leakage and deformation, which is manifested by air leakage, shape changes, vibrations, and abnormal sounds. The air leakage gradually becomes larger and larger, the sound becomes louder and louder, and the pipe wall becomes thinner and Gut bag, this is a process of quantitative change. At this time, if the inspection personnel turn a blind eye and do not take it seriously, or do not discover and handle it in time, the pipeline will burst and an accident may occur.

    By using the "look, smell, ask, and feel" method to conduct inspections, you can promptly discover the characteristics that will inevitably be reflected in the process of quantitative changes, deal with them before the equipment accident changes qualitatively, actively prevent qualitative changes, and prevent accidents. occur.

★If you want to look forward, you must be diligent.

    When inspecting equipment, inspectors should look in all directions and make full use of their eyes to detect leaks, leaks, leaks, and leaks from the appearance of the equipment. They should also discover whether the equipment is in good condition through changes in the position and color of the equipment and even parts. in normal state. Prevent signs of accidents from running away under your nose.

★Smell, you should listen carefully to your ears and nose

    Inspection personnel should listen in all directions and make full use of their noses and ears to detect changes in the smell of the equipment and whether the sound is abnormal, so as to find out the equipment in abnormal conditions and carry out targeted treatment.

★Ask, be diligent in speaking

    Inspection personnel should ask more questions. First, they should ask themselves a few whys. Asking questions is also a process of using the brain. If you don’t use the brain, you will turn a blind eye. The second is that during the shift handover process, we should ask clearly about the work of the previous shift and the unfinished work, and have a detailed understanding so that we have a clear understanding of it; the person taking over the shift should explain every detail clearly to prevent accidents from happening. During the shift change interval.

★Everything needs to be done diligently

    As long as the inspection personnel can touch the equipment with their hands or special inspection tools, they should use their hands or special tools to feel the temperature changes and vibrations during the operation of the equipment. Before operating the equipment, simulate the operating actions and procedures with bare hands. Be careful not to touch randomly with your hands, which may cause misoperation.

     The four inspection methods of 'looking, smelling, asking, and feeling' are based on the functions of the eyes, nose, ears, mouth, and hands of the inspection personnel, and the shape, position, color, smell, sound, temperature, vibration, etc. of the operating equipment are detected. A series of aspects, comprehensive monitoring. From the changes in the above aspects, abnormal phenomena can be found and correct judgments can be made.

The four methods of "looking, hearing, asking, and sensing" are a systematic method of judgment and should not be isolated from each other. They are often used in combination. As long as the inspection personnel fully implement the five inspection methods, mobilize people's sensory functions, and make reasonable use of the four inspection methods of "looking, smelling, asking, and feeling", they can detect the quantitative changes in the equipment before the accident, deal with it in time, and ensure the safety of the equipment. run.

5. How to conduct inspections

The most important thing is to be familiar with the production process and understand the production equipment.

Frequently go in-depth to observe the use and operation of equipment on-site, become familiar with operating procedures, and treat specific equipment in detail. The key point is to conduct inspections carefully, use your hands more often, use your brain frequently, and accumulate experience. When installing, you must first protect yourself, wear labor protection supplies, keep in touch with the indoors, and report back, especially if you find major leaks, or leaks of toxic and other substances, never pretend to be a hero, oh oh oh, report back, or else you will Hang up first.

    Especially in the inspection of production equipment in chemical plants, the focus is to discover signs and hidden dangers that endanger safety, and to deal with and report them in a timely manner. 'Safety' here includes three aspects, namely personal safety; equipment safety; product safety.

Equipment inspection content:

    General 'run', 'drip' and 'leak' problems. Check whether the basic instrument parameters of the equipment are normal, such as: pressure, temperature, flow, vibration, oil level, etc. Check the connection parts of important equipment, such as the coupling of the reducer, and the sound of the reducer. The location of the lubricating oil and the aging condition of the lubricating oil, the feet of the reducer, etc. Check whether there are any illegal operations and the equipment handover situation, and adopt inspection methods such as first look, second listen, and third touch.

First look: Check its operating status and the status display of related indicating instruments (pressure, temperature, oil level, etc.);

Second listening: listen to its operating noise to see if there are any abnormal sounds;
