单齿转子鼓风机具有内压循过程，理论上比等容压缩的罗茨鼓风机节能，但实际过程中存在其它因素影响节能效果。以端面排气的异形单齿转子鼓风机为例，对影响其节能效果的主要因素进行了理论分析和试验验证。 Single-tooth rotor blower with internal pressure through the process, theoretically energy-saving than the compressor Roots Blower energy saving, but in the actual process there are other factors that affect the energy-saving effect. Taking the end face exhaust single-tooth rotor blower as an example, the main factors influencing the energy-saving effect are theoretically analyzed and verified by experiments.
