Powder feed slow
Symptoms:
Screw conveyor feeding slowly, feeding for more than 2 minutes, and normal feeding in 20 seconds or less.
Analysis:
Influence factors include powder tank damage of screw conveyor and cutting is not smooth. Powder feed poor play arches in the form of powder, powder material caking of discharging of the tank, and a discharge butterfly valve open through small, insufficient material in powder cans, etc. Screw conveyor spiral blade deformation damage was mainly, not normal delivery.
Treatment methods:
1, open air arch-breaking devices.
2, check the powder tank discharge disc valve opening and the butterfly valve is in the fully open position.
3, check the powder tank outlet stores from lumping.
4, check whether the spiral blade deformation, if deformation correction or replacement.
Belt deviation
Symptoms:
No-load or load of belt conveyor during operation, there is on a deviation or a left and a right, and causes a material leakage and non-normal wear and tear, reduces productivity, but also the whole equipment working properly.
Analysis:
The external force on the tape in the tape width Heli is not zero, or in the direction perpendicular to the belt width direction tensile stresses caused by uneven. Because of the many factors that lead to misalignment of the tape, so from the conveyor's design, manufacturing, installation, commissioning, operation and maintenance to address the deviation of belt, such as adhesive tape on both sides of the tightness, tape both sides some of seniority, idler brackets and other device is not installed with the tape running direction of the belt deviation caused by fine vertical cross section.
Treatment methods:
By 1, adjust the tensioner
Tape is running, if in the case of no-load and overload into the same lateral deviation shows tape on both sides is less elastic; if the tape was running around with no fixed direction, then the tape slack, adjust the tensioner.
2, adjust the roller method
If the tape runs at the drum is about rollers installed under a horizontal, axial movement, or one end of the drum in the front end in the post. At this point, correction roller horizontal and parallel, and so on.
3, adjust the idler bracket (or frame) method
If the tape in idling when slanting to one side, then the idler bracket for lateral deviation should be moved forwardalong the belt running direction 1-2cm or idler bracket on the other side (or chassis) are properly raised.
4, clear adhesive method
Rollers, rollers having material on local, will enable the diameter increases, causing the belt tension increases, resulting in misalignment. Clean adhesion of materials in a timely manner.
