In recent years, the number and functions of experimental instruments and equipment have been continuously improved, and large-scale sophisticated instruments have been introduced into the laboratory. While improving the efficiency of the experiment, it also brings a series of problems, such as how to strengthen the maintenance and management of the equipment and improve the service life of the equipment. In the process of using experimental equipment, it is inevitable that there will be problems such as unstable signals, large data fluctuations or crashes. Only when problems are discovered in time can we solve and eliminate problems, and ensure that experimental instruments serve the teaching and research services in the best working condition.
Laboratory equipment maintenance is a regular and long-lasting job, and reasonable use is a necessary part. If the experimental instrument is stored in an improper position, it will be exposed to moisture, exposure, corrosion, and poor ventilation. This will result in damage to the surface of the instrument, rust, failure to operate properly, reduce accuracy, and even cause internal circuit short circuit and leakage; There are many samples to be tested belonging to strong acid and alkali, etc. If they are in contact with the surface or inside of the instrument during use, they will not be wiped clean in time, and the corrosion instrument will also affect the service life. The professional requirements for the maintenance of instruments and equipment are strong. Some technicians lack professional maintenance knowledge, and the maintenance system is not perfect enough, resulting in long maintenance intervals and high maintenance costs.
There are several aspects to the maintenance and proper use of the equipment:
1. Guide the user to use the instrument correctly. Before the experiment, the operator should carefully read and understand the operating methods, operating procedures and safe use regulations of the laboratory equipment.
2. Establish a sound management system. When the new instrument comes into play, it is necessary to open the box for acceptance, check the specification, operation procedure, maintenance card, manufacturer's contact information, etc., and sign the maintenance contract with the manufacturer, and provide professional technical support during the warranty period.
3. Establish a professional technical team to do daily maintenance. Today, laboratory equipment management is still lagging behind, lacking professional skills, equipment management and maintenance knowledge. The various instruments in the laboratory have both commonalities and characteristics such as blast drying ovens and vacuum drying ovens. Only after professional training and mastery of professional skills can the users clearly distinguish these commonalities and characteristics, so as to ensure the maintenance of the equipment and equipment can be improved, reduce the frequency of failures, extend the service life, and provide better services for experimental teaching and scientific research.
