The rotary feeder plays a feeding role in the pneumatic conveying system and is widely used in industries such as chemical, food, and grain processing, for the positive and negative pressure conveying of powder particles. Below is an introduction to the main functions and correct installation methods of this device.

供料器采用带副唇旋转油封和特殊填料密封结构，密封可靠，它的关键件采用加工中心加工，产品精度高、间隙小，它的机体设置了均压吸气口，能将回转带来的高压气体带走，有利于物料的供给。

The feeder adopts a rotating oil seal with a pair of lips and a special packing sealing structure, which is reliable in sealing. Its key components are processed by a machining center, with high product accuracy and small clearance. Its body is equipped with a pressure equalizing suction port, which can take away high-pressure gas brought by rotation, which is conducive to material supply.

为了保证该设备的使用效果，应在安装前检查构件，像是轴承、涡轮蜗杆等，若是发现磨损严重应及时更换，安装轴承时可用铜棒、尼龙棒轻轻敲击。等做好这些才可以将轴承安装到蜗杆上，然后注满润滑脂。

To ensure the effectiveness of the equipment, components such as bearings and worm gears should be inspected before installation. If severe wear is found, they should be replaced in a timely manner. When installing bearings, copper or nylon rods can be gently tapped. Only after completing these steps can the bearing be installed on the worm and then filled with lubricating grease.

旋转供料器装涡轮时，安装好后应紧固定位螺栓，然后将涡轮支座装到涡轮室上，再次调整紧固螺柱，待装好涡轮室端盖后，注油到1/2～2/3处。需要注意的是，安装的涡轮室端盖垫应完好无损，以防后期在使用时发生泄漏。

When installing the turbine on the rotating feeder, the positioning bolts should be tightened after installation. Then, the turbine support should be installed on the turbine chamber, and the fastening bolts should be adjusted again. After installing the turbine chamber end cover, oil should be injected to 1/2 to 2/3 of the position. It should be noted that the installed turbine chamber end cover gasket should be intact to prevent leakage during later use.

紧接着就是安装弹簧、蜗杆联轴器，电机装到支座上，在安装的时候一定要调整好同心度，紧固好螺栓。安装它的蜗杆时调整好与涡轮同心度，并且设备的偏差要小于O.1mm。要让它的电机轴与蜗杆同心度的偏差小于0.1mm。

Next is the installation of springs and worm couplings, and the motor is installed on the support. During installation, it is necessary to adjust the concentricity and tighten the bolts. When installing its worm, adjust its concentricity with the turbine, and the deviation of the equipment should be less than 0.1mm. Make sure that the deviation between its motor shaft and the concentricity of the worm is less than 0.1mm.
