旋转设备,轴与轴瓦作相对运动产生摩擦.为减轻摩擦,根据设备容量、载荷、转速的不同,各自采用不同的对策.对于大型或高转速设备,由于其转子重量大或转速高,即转动时离心力也大的原因,都采用向轴与轴瓦间送入一定压力的润滑油,而且一定要讲究进油口方位.我厂热电联产,压差发电制盐在其汽轮发电机的润滑系统中,汽轮机轴承进油方位是对的,但发电机轴承进油却有问题.如图1所示.当发电机轴朝上旋转,将进油向上带动.安装单位按制造厂的图纸施工,但峻工后,做泵油试验
In order to reduce the friction, different measures are taken according to different capacities, loads and rotational speeds of the equipment, and for large or high-speed equipment, the weight of the rotor is high or the rotational speed is high Centrifugal force is also a large reason, are used to send a certain pressure between the shaft and the bearing oil, and we must pay attention to the orientation of the inlet. I plant cogeneration, pressure generation salt in its turbine generator lubrication System, turbine bearings into the oil position is correct, but there is a problem with the generator bearings into the oil, as shown in Figure 1. When the generator shaft is rotated upward, the oil will be driven upwards. Installation unit according to the manufacturer’s drawings construction , But after finishing work, do pump oil test
