Screw conveyor problems that may occur in use
Some people may experience problems using the shaft fracture screw conveyor in the process, and of course the main cause of shaft breaking, what does? Then on a first-come simply to introduce you! Users appear in the process of using the case of the screw conveyor screw shaft fracture, screw conveyor shaft fracture has the following main reasons: intermediate hanger bearings clogging spiral blade is dead material card. 1, long distance screw conveyor is connected by a section of the body together, by hanging bearing connecting screw shaft helical and helical previous section after section is connected via a coupling shaft ce certified yhzs25 mobile industrial concrete mixers intermediate bearing hanging on the tile coupled with bolt coupled together. Screw bolts, by the effect of two forces: First, by its own tightened after preload. Second, the helical rotation twisting torque acting on the bolt shear. If the material particles are too large, rotating blades during the collision with the material, the blade is easily damaged, and easy to get stuck blade, causing the screw shaft fracture. 2, the material into the hanger bearings, hanger bearings so that the material inside is clogged, the screw shaft is stuck, can not move, it's likely to cause the screw conveyor shaft fracture.
Therefore, the screw conveyor maintenance is essential for the production activities of one link. If you pay attention to maintenance of the equipment will reduce the life of the equipment used in the process. Also we need to remind users: screw conveyors must pay attention before using fixed, avoid the use of the device occurs during shaking.
Screw conveyor classification and composition:
Screw conveyors and conveying form divided into two kinds of shaftless screw conveyor screw conveyor shaft, in the shape into a U-shaped tube screw conveyor and screw conveyor. A shaft screw conveyor applies to non-sticky powder materials and small particles of materials (for example: cement, fly ash, lime, grain, etc.) without shaft screw conveyor for easy wound by a viscous material. (Example: sludge, biomass, waste, etc.) screw conveyor works rotation spiral blade will be the passage of a screw conveyor transporting material, so that the material is not rotated together with the screw conveyor blade force is the material of its own weight and screw conveyor friction of the material of the housing. homemade twin-shaft concrete mixer js1000 Rotating shaft helical screw conveyor welding blades, blade surface type according to different entities face conveying the material type, belt face, the blade surface type and other types. Screw conveyor screw axis direction movement of materials in the terminal there thrust bearings with the material to spiral axial reaction force, the longer the captain, should be added to the intermediate hanger bearings.
Shaftless screw conveyor opens up new application areas screw conveyor, the material characteristics of these areas should not be determined by a conventional screw conveyor for material transport. Shaftless screw conveyor can be used to convey an adhesive, adhesion, semi-solid, slurry, bulk and solid-liquid mixture fibrous. Mainly used in sewage treatment, paper and pulp, construction materials, agricultural products and food processing, bulk material handling industries.
