回转式鼓风机效率高，能耗低。风机转子采用特定设计，啮合曲线为优良的复合型线，密封好，泄露少，容积效率进一步上升。开始使用时，注意观察料流的情况，通过调整板调整料流通过的截面大小，实现对料流速度的控制。

The rotary blower has high efficiency and low energy consumption. The fan rotor adopts a specific design, and the meshing curve is an excellent composite profile, with good sealing, less leakage and further increase in volumetric efficiency. When starting to use, pay attention to the material flow, and adjust the section size of the material flow through the adjusting plate to control the material flow speed.

回转式鼓风机的配套电动机容量选取偏大。设备噪音低。设备进、排气口采用了螺旋结构，使它的进排气随转子的旋转而逐渐进行，免除了旧式设备因很快打开和关闭而产生的脉动和噪音，因此设备运转平稳，噪音低。产品配套的消音器采用了优良的吸声材料和特定结构，也有成效的减低了设备的噪音。

The supporting motor capacity of rotary blower is too large. Low equipment noise. The air inlet and exhaust ports of the equipment adopt spiral structure, so that its air inlet and exhaust are gradually carried out with the rotation of the rotor, eliminating the pulsation and noise caused by the quick opening and closing of the old equipment. Therefore, the equipment operates stably and has low noise. The silencer matched with the product adopts excellent sound-absorbing materials and specific structure, which also effectively reduces the noise of the equipment.

回转式风机运转平稳，无振动。采用优良的叶轮加工加工中心，使转子啮合间隙均匀一样，并形成平衡状态，在此基础上，设备转子经过越精密的动平衡实验，使设备运转基本无振动。

The rotary fan operates stably without vibration. The excellent impeller machining center is adopted to make the meshing clearance of the rotor uniform and form a balanced state. On this basis, the more precise dynamic balance experiment of the equipment rotor is carried out, so that the equipment operation is basically free of vibration.

设备安装前应检查透气层是否有损坏，或受雨水浸泡等现象。若存在，则应消掉，以免造成串风或堵塞。设备离溢流锁风阀较远时，连接管道定要加支撑，以防产生振动。

Before equipment installation, check whether the breathable layer is damaged or soaked by rain. If it exists, it shall be eliminated to avoid cross wind or blockage. When the equipment is far from the overflow air lock valve, the connecting pipeline must be supported to prevent vibration.
