Chain swing is one of the common problems in the use of screw conveyors. If the user does not pay attention, long-term use can cause other components of the bucket elevator to malfunction, such as chain tripping or chain cracking. Therefore, the protection of the equipment can not be careless, and any minor problems should be resolved in time.
Usually, after we install the screw conveyor, we need to run it at no load and then reload the load without any anomalies. As the volume of material increased, it was found that the screw conveyor exhibited the appearance of the tail chain chain teeth and the chassis vibration.
In this regard, we must perform a detailed inspection of the screw conveyor, including lifting the hopper's undulations in the casing; whether the head wheel is worn; whether the head wheel is skewed, etc. Due to long-term work, the chain, the head wheel, the tail wheel gear, etc. may have a certain degree of wear, and the axle pin on the chain link of the screw conveyor will also wear to a certain extent, resulting in a certain degree of looseness of the chain. The chain will shake during the operation of the screw conveyor.
If the chain of the screw conveyor is rocked with the head wheel, the chain and the gear are not properly meshed, resulting in noise. A simple and effective way to solve this problem is to adjust the tensioner lift bolts to tighten the chain.
Since the screw conveyor inevitably exhibits the appearance of the material during the unloading process, the material overflows on the head wheel or the tail wheel, forming the head wheel and the tail wheel covered by the material, and even during the lifting process, the gear slip increases. Gear wear.
The tail gears of the screw conveyor have different degrees of wear, and the single chain plates of the chain also wear a lot of dents. The head and tail wheels must be inspected in time for timely cleaning of the head and tail wheels. Material, if the broken teeth are replaced in time, so as not to affect the equipment work.
When the screw conveyor is running, if the front and rear wheels are not on the center line, the chain will form severe wear, and long-term use will lead to cracks in the future. In this regard, the direction of the bucket wheel and the screw conveyor tail wheel should be adjusted, the centerline should be identified, and then commissioned.
