      In theory, the lower the temperature, the higher the energy efficiency, but in practice it is the opposite. When the temperature is too low, the water discharge is not complete. Too much water will not only affect the quality of the lubricating oil, but also increase the oil partial pressure difference and reduce the energy efficiency of the air compressor. Comprehensive consideration, the operating temperature is recommended to be set at 85 ~ 90 degrees, and the user is reminded that the oil bucket should be drained frequently.

  The impact of lubricating oil on the energy efficiency of air compressors is mainly in the following two aspects

  1. Lubricating oil viscosity

  Generally speaking, the greater the viscosity of the lubricating oil, the greater the resistance and the lower the energy efficiency, but this is not absolute, and the viscosity of the lubricating oil is mainly selected according to the conditions of the machine. For air compressors with small rotor clearance and good sealing performance, choose low-viscosity lubricating oil, so that the running resistance will be smaller and the energy efficiency will be higher, such as No. 32 lubricating oil; air compressors with large rotor clearance and poor sealing performance For the press, use lubricating oil with a slightly higher viscosity, which can improve the sealing performance, such as No. 46 lubricating oil.

2. Lubricating oil carbon deposits


  If dust is the largest pollution source of air compressors, then carbon deposition is the second largest pollution source of air compressors. As mentioned earlier, after the lubricating oil runs through a maintenance cycle, the aging speed will be accelerated, and the speed of carbon deposition will be exponentially doubled. The selection of high-quality lubricating oil will greatly reduce the generation of carbon deposits. The less carbon deposits, the smaller the oil partial pressure difference, and the higher the energy efficiency of the air compressor.
