1.The screw shaft is suddenly stuck. The first reason is that the feed is too fast and the load suddenly increases. The second is that the oil has many hard shells and is dry, and the resistance is large. The third is that the gap between the cake openings is too small and the cake ring is not smooth. Fourth, the body temperature is low. Fifth, hard objects enter the press chamber with the oil. The corresponding elimination method is to stop immediately and pour out the cake residue in the press chamber. The second is to remove the hard shell and adjust the moisture of the oil. The third is to adjust the gap between the pie mouth and polish the pie ring. The fourth is to increase the body temperature. The fifth is to take out the hard objects and cake residues in the press chamber.
2.There is an abnormal scream. The first reason is that metal stones enter the body. The second is that the fasteners are loose. The third is poor lubrication. The fourth is uneven or excessive cutting. The corresponding elimination method is to stop and clean up immediately. The second is to tighten the screws at various parts. The third is to add lubricating oil in time. The fourth is to add evenly.
3.The oil output rate is unstable. The first reason is that the dry humidity of the oil is not suitable. The second is that the sliver gap is too small or blocked by slag. The third is that the body temperature or material temperature is too low. The first elimination method is to adjust the oil moisture. The second is to check the sliver gap, and adjust and clear the oil passage. The third is to increase the temperature of the machine or the material.

4.The cake is not smooth, the thickness is uneven, and the surface is not smooth. The first reason is that the cone of the out-of-the-cake ring and the spindle is not smooth. The second is that the pressing of the snails is not the same as the pressing of the chamber. The corresponding adjustment method is to polish the surface. The second is to adjust the concentricity of the screw press and the press chamber.
5.Low productivity. The first reason is that the snails are severely worn. The second is too much slag leakage. The first solution is to replace parts. The second is to adjust the sliver gap or replace with a new sliver.
6.The oil is turbid. The first reason is that the oil is too dry. The second is the low body temperature. The solution is to adjust the oil moisture and increase the machine temperature.
7.Slagging is serious. The first reason is that the sliver is worn and the gap is too large. The second is that the press chamber pressure is too high. The solution is to replace the squeezing sliver, adjust the gap, and adjust the gap between the cake outlet.
8.The cake is too thick, and the adjustment handwheel cannot be adjusted. The reason is that the thread is blocked by slag, so the debris in the thread should be removed in time.
9.Oil is stored in the feed port. The first reason is that the gap between the slivers is small and the oil content is high. The second is the blockage of the sliver gap. The elimination method is to properly increase the oil output gap and clean the press chamber.
10.The belt is slipping. The first reason is that the belt is too loose, and the tension belt of the motor bottom plate should be adjusted. The second is to bring oil, shorten the belt and wax the belt.
11.The bearing and sleeve are overheated. The first reason is that the lubrication is poor and the oil hole is blocked. The oil passage should be cleared in time. The second is that the spindle speed is too high and the installation is not concentric. The speed should be reduced and the concentricity should be checked.
