(1) bag are super poor and ultra-poor is very serious
Such a problem, first observed phenomenon is aniseed door, gate or small scale feed hopper doors one appeared abnormal phenomenon, that does not shut off. That is, after the start feeding scales, large and small scale feed hopper door or a door is always open, can not shut itself down. After careful examination can be found, the solenoid valve is always charged the corresponding charging door, through analysis confirmed that this phenomenon occurs because the PLC output relay due to the high frequency caused by the use of adhesive contacts the interior, resulting in can not be disconnected. The solution is to replace all the way to the output of the PLC, and change its corresponding program. There is also a phenomenon three kinds of materials door movement disorders, but its corresponding solenoid valve power supply is normal, this failure is caused by the mechanical parts inside the solenoid valve failure caused by the replacement valve problems can be solved.
(2) consecutive bags appear occasionally tolerance phenomenon, and not out-of-tolerance values
Now these phenomena, the observed phenomenon is the entire device is operating normally, but after careful examination, aniseed door during closing action is not smooth, catching a momentary phenomenon. Since the finished product flow speed, catching the moment will cause a lot of the finished product falls into a hopper scale, resulting in tolerance. Aniseed reason appears when you close the door catching on because of aniseed door attached to a lot of dust, the dust after fouling reduces the space under the door spout aniseed and aniseed between the door and the door of the small material, thereby aniseed action caused the door is not smooth, it caused a tolerance phenomenon, with hot water to clean up after the dust fouling problems can be solved. To prevent this from happening, the door must be cleaned regularly feed on its dust.
(3) by weight in a small area can not be stable, occasional tolerance
The problem occurs, the first response to the boom on the hopper scales to check to see whether loose phenomenon, because the boom is connected to the load cell and scale hopper member between the boom loose will cause the load cell measurement instability. Also check their sensor wiring board, to see whether the circuit board Weld or sealing off the phenomenon, these are the reasons may cause tolerance phenomena.
