LS-type screw conveyor (also known as auger conveyors) structure, advanced technical indicators, head, tail bearing housing to move outside, hanging among rolling bearings, sliding two interchangeable structures are located dust seal device has a cleaning device discharge end, low-noise and adaptability, easy operation and maintenance, expected out of position flexible layout. Second, the application range: screw conveyor is widely used in various industrial sectors such as building materials, electricity, chemical, metallurgy, coal, aluminum and magnesium, machinery, light industry, food and food industries; for horizontal or less than 20 ° inclination, conveying powder, granular and small bulk materials, such as cement, coal, grain, fertilizer, ash, sand and other material temperature below 200 ℃. Not screw conveyor transporting perishable, viscous, easy caking materials because these materials at the time of delivery will be bonded to the spiral, and rotates without moving forward or volume of material is formed in the hanging bearing plug, leaving screw machine is not working properly. Third, the classification screw diameters from 200 mm to 500 mm, a total of five sizes, lengths from 4 m to 70 m, at intervals of 0.5 meters to a file, when the selection of standard nominal length, special needs can be further raised when the optional type . Screw conveyor drive is divided into two ways: C1 Method - When the screw conveyor length is less than 35m, single-ended drive. Method C2 - When the screw conveyor is greater than 35m, double-ended driving. By screw conveyor into the middle of hanging bearing types: M1- rolling bearing hanging, using 80,000 seals bearings, shaft cover and another dust seal structure, commonly used in easy refueling, without refueling or oil pollution on local materials, sealing effect, hanging long bearing life, conveying the material temperature ≤80 ℃ (do not specify when ordering). M2- hanging sliding bearing, dustproof sealing means, transportation of materials commonly used in relatively high temperature (> 80 ℃), or conveying a liquid material. Fourth, the model significance: six, screw conveyor screw conveyor installation technical conditions after installation correctness is one prerequisite for the use of good, which is installed in a location to be properly carried out and meet the requirements of technical conditions. A screw conveyor screw installed base of machines should be at least 20 days before the formal installation of watering is completed, the foundation should be securely supported conveyors and ensure that different ground sinking too small screw machines and additional changes to ensure the screw machine have sufficient stability during operation. 2, screw conveyor must be installed before those in transit or unloading boxes glue the parts to be cleaned of dirt. 3, should be connected to the adjacent housing flange stone formation, adhesion, joint dislocation inside the casing surface deviation of no more than 2mm. 4, between the housing flange allows the pad to adjust the accumulated error asbestos enclosure and screw length. 5, the gap between the screw and the chassis in vitro should be consistent with the provisions of Schedule III, a minimum clearance of not less than the value specified in the table of 60%, a large gap, according to user requirements. 6, each of the intermediate screw conveyor bearing suspension shall be securely fastened to the chassis lug, and even after linking adjacent spiral helix uniform rotation, no stuck phenomenon, when installed in the chassis and the chassis hanging bearing lug shim between plus adjustments to ensure that after each hanging bearing coaxially mounted coaxial helical axis of the body should be consistent with the provisions of Schedule IV. 7, coaxial screw conveyor shaft should be consistent with the deceleration of electrical GB1184-80 "working poor shape and position, not individual tolerance requirements" Schedule 4 10 requirements. 8, each base chassis mounted screw conveyor after properly, should make it really then tighten ground screw. 9, all the screws should be tightened to join reliable degree. 10, expected out on-site installation should be expected out of the bearing surface of the flange and screw machine body parallel to the axis, and is connected to the flange should fit tightly, without gaps. 11, screw conveyor installed after properly should check whether the existence of the people enough lubricating oil, then add a little inadequate, the subsequent no-load test; more than four hours in continuous commissioning, check the correctness of the screw conveyor assembly that do not meet the following conditions should immediately stop, and then deal with the operation until it is in good operating condition so far. ① screw conveyor should be smooth and reliable operation, no loose fasteners. ② two hours after the operation bearing temperature ≤30 ℃, lubricated sealed. ③ reducer no oil leakage, no abnormal sound, electrical equipment, couplings safe and reliable. ④ load running power ≤ 30% of rated power. Seven, use and maintenance of the screw conveyor screw conveyor is used to transport powder, granular, small general-purpose bulk materials handling equipment, all kinds of bearings are in dust work, so in this spiral machine working conditions reasonable operation and maintenance on a greater significance, screw machine operation and maintenance of the main requirements are as follows: 1, screw conveyor should start no-load, that is no material in the cabinet at the start, after starting to spiral machine can only feed . 2, when the initial feed screw conveyor, should be gradually increased to reach the rated speed of the feed conveying capacity, feeding should be uniform, or likely to cause delivery of materials product plug, drive overload, so that the entire machine early damage. 3, in order to ensure that no-load starting screw machine requirements, before stopping the conveyor should stop feeding, and other materials before they stopped doing completely lost inside the casing running. 4, the material is transported within the bulk material shall not be mixed hard to avoid damage to the death spiral spiral card machines. 5, in the use of screw machine regularly review the work of the various parts of the state, pay attention to the fastening parts are loose, loose parts, if found, should immediately tighten the screws, so that re-tighten. 6, should pay special attention to the coupling shaft between the spiral screw is loose, if found should immediately stop this phenomenon, Correction. 7, screw conveyor cover while the machine is running should not be removed, so as to avoid accidents. 8, screw conveyor operation occurred irregularities should be checked, and eliminate it, not be forced to operate. 9, each screw conveyor moving parts should always add oil.
