In fact, the normal operating temperature of screw air compressor parts is 75°C-95°C, and if it is higher than this temperature, it is considered a high temperature. How much is the gas flow per minute under the rated working pressure of the laboratory air compressor, and it is necessary to ensure a continuous and stable gas flow, so the requirements for the working stability of the air compressor are very high. At present, there are many brands on the market, good and bad are mixed. When choosing, you should consider the products of well-known brand manufacturers with mature technology. The laboratory air compressor is a high-precision instrument with the characteristics of continuous and stable work, simple operation, safe use, environmental protection and energy saving. At the same time, in order to create a good working environment for laboratory staff, especially the requirements for noise control are very high. Therefore, the air compressors that provide air sources for experimental equipment are quite different from the general industrial air compressors. There are many reasons for high temperature in life. Only by reasonably analyzing and judging the cause of high temperature can the problem of high temperature be solved. The reason why the temperature of the air compressor is too high is briefly introduced.
The first type: lack of lubricating oil
Screw air compressor lubricating oil not only lubricates the seal, but also can be used to cool the unit, also known as "coolant". When the machine lacks coolant, the heat generated by the compressor is not cooled, and the higher the temperature, this is also the cause of the screw air compressor. One of the most important factors of machine temperature.
Solution: Add compressor oil, if it is caused by high temperature lubricating oil deterioration, replace.
The second type: the cooler is blocked
Coolers are also known as "radiators". The lubricating oil circulating in the screw air compressor must be cooled by the cooler before it can flow back to the compressor host. When the cooler is too dirty and blocked, the lubricating oil of the air compressor cannot be cooled, and it will cause high temperature when it is recycled.
