A blower operating conditions, the transmission medium inlet temperature is usually not more than 40 ℃. 2, the content of the medium particles should not exceed 100mg / m3 blower, half the maximum particle size must not exceed the minimum operating clearance. 3, the operation bearing temperature not higher than 95 ℃, the oil temperature is not higher than 65 ℃. 4. Use the boost pressure shall not exceed the limits prescribed on the nameplate. Performance parameters are mainly a Roots blower, blower pressure, also known as pressure means increased gas pressure within the fan values ??are static, dynamic pressure and total pressure points. Fan pressure units kpa Mpa 2, also known as air volume flow blower to flow through the fan, said the volume of gas per unit of time. Fan flow unit m3 / min m3 / h 3, Roots blower fan input power is the power that the shaft power. And effective power turbine shaft power ratio is called the efficiency. Fan total pressure efficiency of up to 90. Roots blower power unit for KW. 4, fan speed, noise and vibration size is also an important indicator blower design parameters.
