几年来,我们在石粉厂使用安装高压风机的设计中,采用了两台风机合用一根主轴的尝试(如图),并改原油脂润滑为油浴润滑,获得显著成效:①减少了1对滚动轴承和4只油封的摩擦功率损失,截减原有三角皮带的总根数,降低传动中的皮带摩擦损耗,从而提高了机械效率,使躯动电机功率比原两台电机的总和减少了2kW,节约了能源;②由分散安装的两台风机合装为一整体,结构紧凑,占用空间位置少,安装维修容易,管道布局合理,整齐,省去了部分弯头,紧缩直管,减小了风力在管道内的摩擦损失;③两风机左右对称,改
In the past few years, we used the installation of high-pressure fan at the mill to try the two blowers to use one spindle (as shown) and changed the grease lubrication to oil bath lubrication to achieve the remarkable results: (1) a reduction of 1 pair The frictional power loss of the rolling bearing and the four oil seals reduces the total number of original V-belts and reduces the belt friction loss in the transmission, thereby improving the mechanical efficiency and reducing the motor power of the motor by 2kW from the sum of the two motors , Saving energy; ② the two fans installed by the decentralized installation as a whole, compact structure, less space occupation, easy installation and maintenance, pipe layout is reasonable, neat, eliminating the need for some elbow, tighten the straight tube, reduce The wind in the pipeline friction loss; ③ two symmetrical fan, change
