What‘s the difference?
The difference lies in the understanding of modern management, the implementation of management system, and the use of the most advanced equipment with outdated concepts.
Modern team production, more and more inseparable from a variety of processing, auxiliary equipment, no stable operation of equipment, there will not be a normal survival basis of the team.
In contrast, our side, equipment is frequently against our wishes, frequent failure, energy interruption, oil leakage, spare parts, loss of function and so on these equipment caused by the problem, always interfere with the normal work, production site organization activities are always in a state of interruption. Over time, the team leader from the organization of production "combat elite", into the organization of repair, reporting "fire elite".
Similarly, in the face of frequent equipment failure, equipment management department and professional maintenance personnel tired to deal with, work east run west kill, everywhere fire, but still can not get rid of the frontline personnel complain of the bad luck, ultimately, lead to the first line monitor and equipment maintenance personnel at the same time exhausted, helpless.
How to achieve zero failure?
One might ask, wouldn‘t a device last forever from a zero failure point of view, and here we have to distinguish between natural aging and forced deterioration.
The so-called natural aging means that although the equipment is used correctly, the physical and chemical changes take place over time, and the initial performance gradually declines.
The so-called forced deterioration refers to the failure to work according to the proper method, which artificially promotes the deterioration. For example, the place where the oil should be refueled is not refueled, or the amount of refueling is too little or the cycle is too long. Not cleaning the equipment properly and so on, that is, not doing the things that should be done, will contribute to the deterioration of the equipment.
In this way, the service life of the equipment is lower than it should be, much shorter than the life of natural aging. Therefore, the significance of zero fault view is to guide us to correctly understand the fault, do what should be done to avoid forced deterioration, delay natural aging.
So far, the reason why there are still many failures is often not grasp the real cause of failure. Before a failure occurs, there are usually small, hidden defects. If attention is paid to such unobtrusive potential defects that eventually lead to failures before they occur, and improvement is made in time, faults can be eliminated. Thus, the apparent processing of potential defects is the principle of "no fault".
In order to actually promote this work, we derive five countermeasures for achieving zero failure based on the possible causes of failure:
1. Have the basics
The so-called basic conditions, refers to cleaning, refueling, fastening and so on. Failure is caused by deterioration of the equipment, but most deterioration is caused by not having the basic condition 3 elements.
2. Strictly observe the conditions of use
The conditions of use of the machine are determined at the time of design. If the equipment is used in strict accordance with the conditions of use, there will be few failures. For example, voltage, speed, temperature and installation conditions are determined according to the characteristics of the equipment.
3. Restore the device
A piece of equipment, even if it has the basic conditions to ensure the use of conditions, because it is difficult to be perfect, so the equipment will deteriorate, produce failure. So the implicit deterioration is brought to light and restored to its normal state. This means that we should always carry out the correct inspection and preventive repair of the equipment.
4. Improve design deficiencies
Some faults cannot be eliminated even after taking the above three countermeasures. They are often caused by deficiencies or errors in the design, manufacture and installation of equipment. This kind of failure should be carefully analyzed and these defects should be improved.
5. Improve people‘s quality
All the countermeasures have to be implemented by people, who are the most fundamental in the process of achieving zero failure. First of all, everyone should have a serious attitude, professional spirit, secondly, have a correct understanding of the fault, and finally is to improve the professional skills of operation and maintenance personnel.
In general, we should do the following aspects of work in our daily work: to prevent deterioration activities: correct operation, preparation, adjustment, cleaning, refueling, fastening and so on; Activities to determine deterioration: check the service conditions, daily and regular inspection of the equipment to find the hidden trouble early; Recovery deterioration activities: eliminate hidden dangers and deterioration in time to restore the equipment to normal state.
