LS-type screw conveyor uses DIN15261-1986 standards, design and manufacture of JB / T7679-45 "LS-type screw conveyor" professional standards, the maximum length of a single screw conveyor drive up to 35m. 0.5m length of each screw conveyor to a file, can be selected according to need. A, LS-screw conveyor Category 1, according to the screw conveyor drive is divided into (1) screw conveyor length is less than 35m, single-ended drive. (2) the length of the screw conveyor is greater than 5m, double-ended drive. 2, according to the type of screw conveyor into the middle of hanging bearing (1) for rolling bearing hanging. Employ 80,000 seals bearings, shaft cover and another dust seal structure, commonly used in easy refueling, without refueling or materials contaminated place, good sealing effect, hanging long bearing life, conveying the material temperature t≤80 ℃. (2) hanging sliding bearings. There dust seals, there are bronze tiles, tile alloy cast iron, copper graphite lubrication watts less oil, commonly used in the transportation of materials relatively high temperature (t> 80 ℃) or transport liquid materials. LS screw conveyor is generally divided into a shaft screw conveyor, shaftless screw conveyor two kinds. Screw conveyor by the screw shaft, U-shaped slot cover, into and out of the discharge port and drive device component without shaft screw put the screws to shaftless spiral and U-groove device has to reline body, a simple structure. Material from the imported input, output, after the spiral by pushing exports, the entire process can be carried out in a sealed tank, reducing noise, reducing the discharge of odor. LS Screw Conveyor Features: 1, LS screw conveyor head and tail bearing housing to move outside, eliminating the possibility of leakage of material due to Mifengbuyan reduced bearing life. 2, LS screw conveyor middle hanging bearing rolling, sliding two structures are interchangeable, are located dust seals, labyrinth seals, seals, nylon and plastic king, sealing strength, wear resistance, slide There need to add lubricant watt copper tiles, tile and copper-based alloy cast iron graphite tiles less oil lubrication, bearing life up to 10,000 hours. 3. LS screw conveyor spiral blade surface is coated with a wear-resistant material, and its life can be doubled compared to conventional blades. 4, the transmission part adopts cycloid reducer, low noise machine, adaptable, easy operation and maintenance.
