水环式真空泵长时间运行后,受机械振动、磨损等的影响轴会发生前后移动,叶轮与侧盖之间的间隙发生变化,不仅增加叶轮转动的摩擦阻力,也降低了泵体的真空度,严重影响瓦斯抽采系统的高效运行;利用塞尺测量水环式真空泵侧盖的端面间隙,并借助千斤顶及轴向顶丝调整间隙至合理范围;对圆锥滚子轴承的更换工艺及方法进行了详细的描述。
Water ring vacuum pump after a long run, by mechanical vibration, wear and other effects of axis will occur before and after the move, the gap between the impeller and the side cover changes, not only increase the friction impeller rotation, but also reduces the pump vacuum , Seriously affecting the gas drainage system, efficient operation; the use of feeler gauge water ring vacuum pump side cover end clearance, and with jack and axial jacking wire to adjust the gap to a reasonable range; Tapered roller bearing replacement process and method A detailed description.
