If you purchase air compressor parts from an imported company, you can ask them to show the above procedures. Otherwise, it can be judged as non-imported genuine products. In addition, when identifying the packaging of imported air compressor parts, you should also pay attention to the fact that engineering air compressors and air compressor manufacturers have their own professional supporting factory parts suppliers. When importing air compressor accessories from manufacturers, the packaging box will have both the complete machine manufacturer’s mark and the supporting factory’s mark. Finally, identifying imported air compressor parts based on product quality is the most critical step in identifying the authenticity of genuine parts. Driven by profits, some dealers assemble imported genuine parts into complete machines, and then use genuine parts packaging to package non-genuine parts for sale to the market. Therefore, the intrinsic quality of the product must be inspected to confirm the authenticity of imported air compressor accessories. The identification of product quality mainly involves observation, inspection and testing. As more and more policies are adopted to reduce overcapacity in China, many people are worried about a wave of layoffs in heavy industries and the bankruptcy of large and medium-sized enterprises. However, whether it is a developed or developing country, the process of industrialization cannot be stopped. Our country was known as an agricultural country in the 1990s, and its main economic income was based on agriculture and food. At the end of the 1990s, various heavy machinery technologies and complete machines were introduced into the country, and the tide of industrial reform came as promised. In the air compressor industry The most representative thing is that various brands occupy an increasing share in the domestic market. However, since the year, the core of air compressor technology has gradually shifted to domestic production as the mainstream. Many people find that when using screw air compressors , the screw air compressor has a temperature, which is normal. However, if the temperature of the screw air compressor is too high, it will attract our attention, because in this case, it often means that your screw air compressor is faulty, so we need to stop it immediately for inspection. As for which places to check, the editor will introduce them to you here. If the temperature difference is within the normal range but the machine is still high, it means that the calorific value of the machine head exceeds the normal range. You should check whether there is overpressure operation, whether the oil quality is wrong, whether the oil quality is aging, whether there is a problem with the machine head bearing or even end friction. In addition, if there is an oil cut-off valve, check whether the screw air compressor is faulty. If the oil cut-off valve fails, it will usually jump when the machine is turned on and the temperature will rise linearly.
