The screw air compressor is affected by the altitude:
(1) The higher the altitude, the thinner the air, the lower the absolute pressure, the higher the compression ratio; (the higher the compression ratio, the compression (The power consumption of the machine increases)
(2) The higher the altitude, the worse the cooling effect, the greater the temperature rise of the motor; (the higher the altitude, the lower the atmospheric pressure, the lower the pressure of the fan, the worse the heat dissipation effect)
(3) The higher the altitude, the greater the oil-gas ratio. (Increased oil content)
The air is thin at high altitude and the cooling of the motor is damaged. The higher the altitude, the lower the atmospheric pressure, the lower the fan pressure, and the worse the heat dissipation effect. The standard motor can work at 1000 meters without reducing the specified data. When the ambient temperature is 40 ° C or more, Table 1 can be used as a standard motor selection guide. It should be noted that for some forms of Chinese air compressor, the performance of the motor at the plateau is much lower than that required by the compressor.
