旋转供料器在正常情况下，喂料量(即流量）是比较稳定可靠的。如发现未进行调节流量操作，而实际流量波动较大， 小编总结大致有下列几个原因。

　　Under normal circumstances, the feeding amount (i.e. flow rate) of the rotary feeder is relatively stable and reliable. If it is found that the flow adjustment operation has not been carried out and the actual flow fluctuates greatly, the YISHENGHUI Machinery editor summarizes the following reasons.

　　１.刮板下边磨损，不能将盘面上的物料刮净。如前所述可调整刮板上防磨条的位置。若刮板上未装防磨条，则可以；

　　１. The scraper is worn underneath and cannot scrape off the material on the surface. As mentioned earlier, the position of the wear-resistant strip on the scraper can be adjusted. If there is no wear-resistant strip installed on the scraper, it can be done;

　　a.下边磨损不太大时，可修整刮板下边，使其平直，并下降刮板位置，使其下边与盘面接触。

　　a. When the wear on the bottom is not too great, you can adjust the bottom of the scraper to make it straight, and lower the position of the scraper to make it in contact with the disc surface.

　　b.如磨损大，则需更换新刮板。

　　b. If there is significant wear, a new scraper needs to be replaced.

　　２.刮板调节丝杆松动，在工作过程中，刮板因晃动而位置有变化。一般可按丝杆重新配制一只螺母，或按螺母配制一根丝杆，消除其因丝杆和螺母配合间隙大而引起的刮板晃动。

　　２. The adjusting screw of the scraper is loose, and during operation, the position of the scraper changes due to shaking. Generally, a nut can be reconfigured according to the screw, or a screw can be configured according to the nut to eliminate the shaking of the scraper caused by the large clearance between the screw and nut.

　　３.物料的粒度均匀性差，在超过规定的大块物料夹入。需要由上一道工序解决。

　　３. The particle size uniformity of the material is poor, and large pieces of material exceeding the specified size are sandwiched. It needs to be solved by the previous process.

　　４.盘面的转速与要求的喂料量不适应，一般喂料量小，盘面转速偏快，易出现流量不稳定的现象，在此情况下，应减慢转速，提高吊筒，使物料厚度增加，使刮出的物料流的断面加大，则在助于提高喂料量的稳定性。

　　４. The rotational speed of the disc is not suitable for the required feeding amount. Generally, the feeding amount is small and the disc speed is too fast, which can lead to unstable flow. In this case, the rotational speed should be slowed down and the lifting cylinder should be increased to increase the thickness of the material and increase the cross-sectional area of the scraped material flow, which can help improve the stability of the feeding amount.

　　５.对敞开式旋转供料器，在安装时，进料管和吊筒的中心线与盘面的中心不在同一垂直线上。从吊筒中溜出的物料在盘面上分布偏向一边，则刮板刮出的物料呈周期性的多少变化。出现这个问题，应重新校正喂料盘与进料管的中心位置。

　　５. For open rotary feeders, during installation, the centerline of the feeding tube and the lifting cylinder should not be on the same vertical line as the center of the disc surface. If the material that slides out of the suspension tube is distributed to one side on the disc surface, the material scraped out by the scraper will show periodic changes in quantity. If this problem occurs, the center position of the feeding tray and feeding tube should be recalibrated.
