The repair of instruments and equipment mainly has two methods: preventive repair and after-the-fact repair. In order not to affect the normal conduct of experimental teaching activities, the laboratory should generally carry out planned and preventive repairs on the equipment. Planned preventive repairs require that attention must be paid to the recording and analysis of equipment failures, and the preventive inspection of equipment and equipment should be strengthened. Found abnormalities, detected hidden dangers, and prepared for planned preventive repair of equipment. There are two principles for repairing equipment: one is not blind disassembly; the other is only the faulty part. Therefore, be careful before maintenance, especially for equipment that has not been touched before, do not rush to open. You must first understand the damage, the phenomenon of failure, according to the construction of the equipment, and then consider where to start repairing. When disassembling, carefully observe the shape, installation position, direction, relationship with the top, bottom, left and right, and the function of the parts. It is best to draw a sketch first to understand its function and reference for installation. . For example, the same screws, because of their different positions, play different roles, some are used for connection, and some are used for positioning. The same resistor, some function as a shunt, some as a partial pressure, and some as a load. The same crystal triode can have different functions such as amplification, oscillation, phase inversion, isolation, and switching. Faulty instruments and equipment, most of which are damaged by individual components, and few parts are faulty. As long as patient inspection, observation, and analysis will always find the location of the fault. This not only saves time, but also does not destroy the original normal state.
Pvc Anti-corrosion Tape, according to different uses, is also called PVC air-conditioning cable tie. PVC Anti-corrosion tape, also known as PVC outer protective tape, is mainly used for anti-corrosion protection of various pipes. The name of the product comes from the base material of the product - polyvinyl chloride diaphragm. So it has the durability and corrosion resistance of PVC. , Easy to wrap, suitable for low temperature conditions, but also suitable for elbows and irregular surfaces. Widely used in ordinary steel pipes, galvanized pipes, stainless steel pipes; anti-corrosion of air-conditioning pipelines.
