The main advantages of the screw conveyor are: structure is simple, compact, cross-section of small size; easy to operate safe, small stainless steel screw conveyor, easy maintenance; low manufacturing cost; chute closed, easy to transport Gigalight materials, can reduce the environmental pollution; arbitrary point in the middle of loading and unloading, screw conveyor design specifications, but also in multi-point loading and unloading. In the annual 5000t workshop, equipped with a variety of screw conveyor dozens, so performance screw conveyor maintenance and repairs carried out smoothly and production are closely related. Seal between the screw shaft and the bearing is double oil seals. A seal on the left side to prevent powder from entering the bearing housing, the right of a seal along the shaft to prevent the bearing grease flowing into the cylinder, contaminated material. Seal, also known as rotary lip seal, in a free state, the screw conveyor, the inner diameter than the shaft seal small, that there is a certain amount of interference. Oil encapsulated into the shaft, the screw conveyor customize its edge pressure and self-tightening spring contractile force of the radial shaft seal hold a certain force, blocking leakage gap, to achieve the purpose of sealing. The higher the rotational speed of the rotary shaft, the greater the friction on the shaft seal, the higher temperature and lower seal life.
