In order to be able to ensure the quality of the acquisition of equipment, before the purchase should do a good job of related investigations and develop a scientific list of acquisitions, in strict accordance with the relevant management procedures for the acquisition period. In this period is most likely to have problems is the safety inspection agency, first, they are not clear in the development of the plan, just see what similar organizations have what equipment they want to buy what equipment, the need for their own development plans do not have a clear understanding. Second, simply purchasing equipment and did not view the requirements needed for safety inspection. Third, before the purchase of market research work is not done, may buy outdated equipment. Fourth, the entire safety commissioning process is just going through the motions, not serious, easy to the later production impact, and the installation and commissioning process has not established a file, which is likely to lead to the loss of equipment-related information. In view of these problems, should strengthen the procurement of safety production testing equipment and commissioning links to pay attention to.
1.1 Procurement of equipment
Enterprises in the procurement of equipment should be based on the needs of the actual production of the enterprise, as well as the future development goals and planning, and changes in the external environment to formulate a reasonable procurement program, to achieve an objective and reasonable configuration of equipment.
The relevant leaders of the enterprise in the approval of the procurement program before the market situation should be carried out research work, and according to the functionality of different equipment and equipment cost-effective and other aspects of the manufacturer's credit should be considered, so as to be able to choose the best instrumentation.
In general, equipment procurement can be divided into two parts, one is to buy equipment, the other is homemade equipment. The so-called purchase of equipment is the production of standard equipment that needs to be configured through the purchase of the way to buy can be. The other is homemade equipment, this equipment is relative to the enterprise safety production has a special nature, they are usually used in some special environment and special testing situation, belongs to the non-standard equipment, so you need to according to the requirements of the enterprise, to find the manufacturer to customize, pay attention to the design of this batch of equipment is best by the measurement of the best staff to join, so that can also provide convenience for the back of the calibration work.
1.2 Acceptance of instrumentation
After the purchase of good equipment, can not be immediately put into use, should first be transported to the laboratory after inspection, installation, commissioning before they can be put into production.
In the inspection, the enterprise and the production side should be present, first of all, check whether the packaging of the equipment is intact, and then in the count whether the number and the enterprise requirements are consistent. In the process of installation, experimental personnel and maintenance personnel should be present and involved, in accordance with the relevant test requirements for good records, which is also the basis for the final acceptance. The key parts of the equipment should focus on inspection and make relevant records and archives, to facilitate later access. Specific file content as shown in Table 1.
2 The main problems and countermeasures during the operation of instrumentation
Generally speaking, the management of instrumentation during operation includes daily maintenance management, calibration management, and regular inspection management during use. Safety inspection regardless of which part is ignored may cause damage to the equipment, affecting the normal use. The current inspection and testing organizations have the following main problems. First, do not pay attention to the daily inspection of equipment, equipment use in the absence of regular inspection and maintenance, for each inspection and calibration also has no relevant records. Second, ignore the regular calibration of instruments and equipment, resulting in the use of instruments and equipment in a certain period of time after a certain error, in order to be able to obtain accurate data, testing and inspection organizations should pay attention to the calibration of instruments and equipment and make relevant records. Third, sometimes even if the calibration equipment, but the calibration results do not pay attention to, that the instrumentation can be used as long as the calibration, but there is no repeated verification of the calibration results. Fourth, the importance of regular inspection is neglected. Think that after calibration in a longer period of time will be no problem, not in the later use of regular checks. These will affect the accuracy of the instrumentation, inspection and testing organizations should pay attention to these issues.
2.1 Daily Operation and Maintenance
Instrumentation needs to be verified before they can be put into use. In the verification process, attention should be paid to checking the quality of the equipment certificate, the relevant content of the logo and the use of equipment, such as expiration date, after passing the inspection can really be put into use. Some equipment should be calibrated before use, but also should be provided in the equipment use certificate calibration data to test, find the correct use of equipment.
In the process of using the equipment, because the production environment may cause pollution to the equipment, make its performance degradation, so the enterprise should send special equipment maintenance personnel to strengthen the daily management of the equipment. According to the instructions on the maintenance time and method of maintenance and maintenance of equipment. In addition, for the use of more frequent equipment, should develop a suitable maintenance plan.
The maintenance of instruments and equipment shall have "Instrument and Equipment Maintenance Record". Each instrument and equipment should also have "instrument and equipment use record", before switching on and off according to the maintenance plan for maintenance, and make a record in the instrument use record book, end of the year for archiving for the future may provide evidence of traceability, while the use of records for the equipment before and after the use of the state of the state of whether or not it is intact to provide evidence. If an instrument or equipment is overloaded or improperly handled during use, gives suspicious results, or has shown defects or exceeded the prescribed limits, it should be stopped or its use should be limited after verification. Instruments and equipment that have been stopped or restricted from use should be isolated, or labeled or marked to prevent misuse. After the equipment is repaired, it should be calibrated or tested to show that it can work properly before it can be put into use.
