Countermeasures and suggestions for laboratory equipment management and maintenance(two)

2. Reasonably configure the process layout of the laboratory

The construction of the laboratory includes: the upgrading of testing instruments and equipment, which has received universal attention in the upgrading of equipment, and that the investment in environmental and space use during the maintenance process can not be ignored. The summer weather is humid, and the instrument such as viscosity analyzer is prone to mold and damage. Especially when the optical instrument is configured, it needs to be placed in a constant temperature and humidity laboratory or a dehumidifier, air conditioner, etc. as a basic instrument to reduce air humidity and reduce maintenance management costs. . In addition, during the maintenance, a large amount of instruments in a laboratory pile are often found, and the importance of interference between the instruments is not valued. In addition, due to the layout of the house, the laboratory space is unreasonably allocated, and some laboratory space is limited. It is necessary to put the test instruments, pools, and precision electronic instruments of a certain test item in a laboratory, which will easily cause serious corrosion of electronic instruments. Some laboratories originally had sewer pipes, which were relatively humid. The placement of electronic balance test equipment had a great impact on the accuracy of the balance; for example, some laboratories lined up the electromechanical equipment used, and the instruments were intimately contacted. Without considering interference and heat dissipation. Therefore, when the equipment is resettled, a comprehensive consideration should be given to the resettlement space to prevent the impact of the equipment and the environment and reduce maintenance costs.

Safety, efficiency and comfort are the three major elements of an ideal laboratory environment. The construction of a laboratory is not only a simple construction of a laboratory and the purchase of reasonable equipment, but also the overall planning, reasonable layout and layout of the laboratory Design, as well as equipment and basic conditions for water supply, power supply, ventilation, safety measures, material transfer, etc. Precise instruments can be considered to avoid the north, and can save air conditioning cooling capacity. The placement of precision instruments should be perpendicular to the window on the north side to prevent shadows or glare; the operation platform should be built on the east side; chemicals should be placed on the west side to avoid direct sunlight. Instruments with anti-vibration requirements, such as mechanics room, balance room, precision instrument room, can generally be built with an operating table. Precision instruments should reduce disturbances such as vibration and dust. The layout of the laboratory shall be convenient for the tester to operate, and the original records shall be filled in quickly and easily.

3. Strengthen the training of operators' hands-on ability

There are generally three reasons for the failure of instruments and equipment. Operators mishandle, poor storage environment and poor quality of the instrument products. From the precision balance supplier ’s experience, the actual situation in the operation of the equipment is caused by the user ’s misoperation. The remaining two are Controllable factors. Therefore, the cultivation of the operator's ability to operate is an important factor to reduce the occurrence of instrument failure. In order to improve the operator's hands-on ability, the laboratory manager should first organize after-sale engineers or maintenance managers of the instrument supplier to conduct practical training before operation. Before doing the test, carefully inspect the main parts of the equipment, carefully observe and operate the connectors of the equipment itself to see if they are plugged, loosened, worn, etc., and remove the dirt, Dust, corrosion, leakage, etc., prevent malfunctions. Secondly, the operator must master the manual and various technical materials and data included with the instrument, and operate it carefully according to the requirements. Professional engineers should train the operators on the use of the instrument, explain in detail the use of the instrument, precautions for use, and the structure of the instrument to prevent malfunctions caused by misoperation.
