Description
技术领域technical field

背景技术Background technique
罗茨风机属容积式风机，叶轮端面、风机前后端盖。原理是利用两个叶形转子在气缸内作相对运动来压缩和输送气体的回转压缩机。这种鼓风机结构简单，制造方便，高效节能于一身，适用于的氢气输送。三叶罗茨鼓风机是罗茨风机的其中一种，三叶罗茨鼓风机由于采用了三叶转子结构形式及合理的壳体内进出风口处的结构，所以风机振动小，噪声低。The Roots blower is a volumetric fan, with the end face of the impeller and the front and rear end covers of the fan. The principle is a rotary compressor that uses two leaf-shaped rotors to move relative to each other in the cylinder to compress and deliver gas. This kind of blower has simple structure, convenient manufacture, high efficiency and energy saving, and is suitable for hydrogen transportation. The three-lobe Roots blower is one of the Roots blowers. The three-lobe Roots blower adopts the structure of the three-lobe rotor and the reasonable structure of the air inlet and outlet in the housing, so the vibration of the fan is small and the noise is low.
现有三叶罗茨鼓风机采用皮带机带动两个互相咬合的齿轮进而带动两个叶轮相向转动，由于齿轮的转动以及叶轮转动摩擦力的影响，进而会造成叶轮升温并造成叶轮箱体内升温，这种升温造成叶轮箱体压力升高，不利于气体的输送而且会造成输送气体升温。The existing three-lobe Roots blower uses a belt conveyor to drive two interlocking gears to drive the two impellers to rotate in opposite directions. Due to the influence of the rotation of the gears and the rotational friction of the impeller, the temperature of the impeller and the impeller box will rise. The temperature rise causes the pressure of the impeller box to rise, which is not conducive to the transportation of gas and will cause the temperature of the conveyed gas to rise.
