Fault analysis of measuring instruments

The measurement and inspection instrument itself consists of three parts: circuit, optical path and gas path. The failure has its own reasons and human causes. The cause of the failure due to the instrument itself can be avoided in the procurement of the instrument. Therefore, the article specializes in human causes. Instrument failure.

1.1

Assembly error

In the process of equipping the instrument, if the staff does not know enough about the relevant procedures, it will lead to problems in the assembly. This situation will cause more serious consequences. For example, the circuit line will be misplaced, and the contact will generally be poor. Seriously, the relevant personnel will be exposed to security threats. There are also parts in some parts that are loosely installed, causing malfunctions.

1.2

Improper placement

If the instrument is in an idle state, the staff must keep it in accordance with the correct specifications, and do not display the wrong situation. Otherwise, there will be various electromagnetic interferences between the instruments. Over time, various instruments will appear together. The fault cannot be used normally.

1.3

Operation error

The metrological inspection instrument will be equipped with the corresponding manual, and the operation flow of the instrument will be described in detail. The operation can be completed successfully according to the specified process. If the staff does not understand the use of the rules, it will inevitably lead to the failure. .

1.4

Maintenance method is not scientific

The instrument needs to carry out the necessary maintenance work whether it is in use or when it is on hold. The instrument should be inspected regularly. After the fault is found, it is necessary to find the maintenance personnel to repair it in time to prevent the instrument from being damaged more. In the process of maintenance, it is necessary to carry out maintenance in strict accordance with the maintenance regulations. For example, if there is any debris in the tube of the instrument, it should be cleaned in time. If it is not cleaned in time, it will cause blockage. If it is corroded, it will also be blocked. Corrosion of the pipeline will result, and the instrument will be damaged and cannot be used. The new equipment has to be replaced, resulting in a gradual increase in the cost and a certain loss for the enterprise.

1.5

No preventive maintenance awareness

In order for the instrument to extend its useful life, it must be pre-prepared for maintenance so that it can function smoothly during use. This can reduce the number of instrument repairs and save on corresponding expenses. The maintenance of the instrument can enable the staff to deepen the understanding of the internal structure of the instrument. It can also correct the error of the staff in the process of inspection. The information technology also has an important impact on the measurement instrument. For such instruments, it is more important. Pay attention to preventive maintenance and maximize the service life.

1.6

Bad temperature and humidity conditions

If the temperature of the working environment is too high, and the heat generated by the instrument itself will cause damage to the circuit, the related components will be damaged, the internal electrolyte will evaporate rapidly, and the entire internal system will have more serious aging in such an environment. The overall performance of the instrument is degraded and the measurement accuracy is low.

Improvement measures for faults of metrological inspection instruments

2.1

Improve the professional quality of staff

The corresponding training will be carried out, and the correct use method and maintenance knowledge of the instrument will be sent to the training staff, and the experienced staff will be invited to explain the technical personnel to improve their technical level and enable them to master. More technology related to instrument use or maintenance. On the other hand, the operator should also be trained to achieve a full understanding of the instrument in a short period of time. A combination of theory and practice should be adopted to allow staff to directly operate in the process of receiving training to test the results of the training. After the training, each staff member will write a corresponding summary report. The experience of this study should also invite experts and scholars in this field to give lectures, so that the staff can accept the influence of advanced ideas, and these workers can be divided into Several discussion groups let them exchange their own learning experiences, so that everyone has a clear understanding of their level of learning and learn the strengths of others. Then, it can be divided into several discussion groups. Each group member can tell each other about their knowledge of the equipment and equipment, and then carry out the exchange debate between the groups. Under this learning form, the professional level of instrument operation and technicians are Can get a more obvious improvement, laying a solid foundation for the prevention and treatment of instrument failure in the future.

2.2

Formulate instrument usage systems and specifications

Purchase the equipment with the best technical content, and then record and register the detailed information of each instrument. It must be issued by a certificate issued by an authoritative department to directly apply it. It is also necessary to set the corresponding account for each instrument. The instrument must ensure that its operators have a complete understanding of the information of the instrument itself, but also know the correct operating procedures and maintenance knowledge of the instrument. Before use, it is necessary to check each side of the instrument in advance, and report the problem to the management immediately, so that the problem can be solved in time, so as not to affect the normal use of the instrument measurement work, the staff should always be on the status of the instrument. Observe and ensure that all parties running are in a normal state, clearing all security risks. If large-scale precision equipment is encountered, the management work needs to be handled by a special person. Anyone who is not approved can not operate the equipment alone and finds that serious punishment is required.

2.3

Placement equipment manager

The purpose of arranging special management personnel is to prevent the instrument from malfunctioning due to human factors. The administrator must not only supervise the use of the operators, but also control all aspects, so that the operators of the instruments can operate according to the formal specifications. The administrator supervises the inspection of the instrument, handles the faults of the instrument according to the maintenance plan, and establishes the inspection time of the equipment to ensure that the instrument keeps the operation information in its own hands, so that the problems of the equipment and the possible existence can be discovered in time. Security risks. At the same time, it is also necessary to participate in the assembly, commissioning and acceptance of the instrument, and check the files related to the equipment. Once the equipment fails, it is necessary to carry out the corresponding investigation work, and to grasp the information such as the cause of the failure, you can make recommendations to the management to regularly check the equipment such as water and electricity and the ventilation situation. If you find the problem, immediately turn off the equipment and look for the maintenance personnel to repair it. The superior reports the specific situation. For some machines that are still in use with minor faults, they have the right to close and report directly to the superior.

2.4

Instrument field fault handling

First of all, it is necessary to know in detail the situation of the fault site. The maintenance personnel should check all parts of the instrument and ask the operator for the specific fault condition. For unexplained failures, all possible causes must be listed, and eliminated one by one. Finally, the detailed book and documents are summarized. Try not to replace the instrument immediately because the fault is damaged, and find the fault and replace the corresponding parts. Due to the differences in the projects operated by the company, the inspection environment will be different. The equipment must be maintained according to the nature of the enterprise, and the equipment should be faulty. Check the surrounding environment, such as smoke and noise. Environmental conditions such as electromagnetics may cause malfunction of the equipment. If it is determined that these external environmental factors cause the equipment to be unable to be used normally, it is necessary to find a way to shield the source of the interference.
