Three lobe Roots (Roots roots blower pumps)
Product Manual
Zhangqiu Mingfeng Machinery Manufacture Co., Ltd.
One, the principle and performance characteristics of MFSR series of three lobe roots blower (Dry roots roots blower pump):
1. Principle: The MFSR series of three lobe roots blower (Dry roots roots blower pump) is a constant volume-free internal compression blower (roots blower pump), It is by a pair of synchronized gear-driven, let a pair of high-precision constant reverse rotation of the rotor, the rotor and the housing capacity of the cavity formed by primitive closed volume of gas discharged from the inlet to the exhaust port to achieve the blower (Pumping gas) purpose of the volume of machinery.
2. Performance characteristics: The MFSR series of three lobe roots blower (Dry roots roots blower pump) In addition to the general blower’s(The following blowers and dry roots blower pumps are referred to as roots blower or blower) exhaust features(That boost or roots blower change, state of the blower inlet flow rate changes little), the blower does not contain oil and other transmission media, general characteristics, it also has its unique advantages: Using the world's most advanced back into the exhaust port and internal structure, effectively delay the return of high pressure gas shocks, so blower , the vibration and noise is significantly reduced.
Two, Technical conditions:
1. Media: The MFSR series of roots blower mainly used to transport non-toxic air and inert gas inlet temperature generally not higher than 40 degrees, gas content of the solid particles is not greater than 100mg/m3, not more than the maximum size of particles within the minimum working clearance blowers half.
2. Life: blower with design life of not less than 10 years before the first overhaul of the safe operation of no less than 1500h.
i, High-pressure Roots Blower Low noise
roots blower with adoption of helical tri-lobe roots rotors and the discharge port of special geometry, the airflow noise is much lower compared to typical straight-lobe roots blower. The noise level can be reduced by 8db in the band of low frequency; hence the noise in the surroundings of blower can be significantly improved.

ii, High adiabatic efficiency
High-pressure Roots Blower with design of helical tri-lobe roots rotors, roots blower the airflow pulsation is less and the air streamline would be more stable. Therefore the fluctuation in airflow is less and then the energy waste can be reduced. Additionally, the instantaneous backflow of discharge is lower by the design of special discharge port. Compared to straight-lobe roots blower, the adiabatic efficiency can be raised up to 20%.

iii, High-pressure Roots Blower Super Energy saving
Compared to the typicalroots blower under the same operation conditions of discharge pressure and airflow volume, the power consumption of helical tri-lobe roots blower will be lower by 20.
