      Application range of LS type screw conveyor: Screw machine is widely used in various industrial sectors, such as building materials, electric power, chemical industry, metallurgy, coal, machinery, light industry, food and food industries.
      LS screw conveyor's requirements for conveying materials, powder, granular and small block materials, such as: cement, pulverized coal, grain, fertilizer, ash, sand, etc. The temperature of the material should not exceed 200 ℃. , Sticky, easy to agglomerate materials. Because these materials will be bonded to a screw when they are conveyed, and then rotate without moving forward, or a material plug is formed at the suspension bearing, the screw machine cannot work normally.
      The working environment of the LS screw machine should be between -20 ° C and 50 ° C. Slight use is allowed, and the maximum inclination angle should not exceed 20 ° C.
      The screw machine should not be used for conveying perishable, sticky, and agglomerated materials, because these materials will stick to the spiral during transportation, and then rotate without moving forward or forming a material plug at the hanging bearing. , So that the screw machine does not work properly. The screw diameter of the LS screw machine ranges from 100 mm to 1250 mm. There are eleven specifications. The length ranges from 4 meters to 70 meters, and every 0.5 meter. The selection should meet the standard nominal length. Special requirements can be found in the optional section. Proposed separately. There are two types of screw drive methods:
      C1 manufacturing method-when the length of the screw machine is less than 35M, single-ended driving.
      C2 method-when the screw machine is larger than 35M, it is driven by the end.

      对输送物料的要求,粉状、粒状和小块状物料,如:水泥、煤粉、粮食、化肥、灰渣、砂子等,物料温度不得超过200℃,螺旋机不宜输送易变质的、粘性大的、易结块的物料。 LS screw conveyor's requirements for conveying materials, powder, granular and small block materials, such as: cement, pulverized coal, grain, fertilizer, ash, sand, etc. The temperature of the material should not exceed 200 ℃. , Sticky, easy to agglomerate materials.

      Use maintenance screw conveyor is a general-purpose conveying equipment used to convey powdery, granular, small block materials. All kinds of bearings work in dust. Therefore, the reasonable operation and maintenance of the screw machine under such conditions With greater significance, the main requirements for the operation and maintenance of the screw machine are as follows:
      1. The screw machine should be started without load, that is, when the material is set in the casing, start it and start feeding to the screw machine after starting.
      2. During the initial feeding of the screw machine, the feeding speed should be gradually increased until the rated conveying capacity is reached, and the feeding should be uniform, otherwise it will easily cause the accumulation of the transported material and the overload of the driving device, which will cause the entire machine to be damaged early.
      3. In order to ensure that the screw machine starts without load, the conveyor should stop feeding before stopping, and stop running after the material in the casing is completely drained.
      4. Do not mix hard large materials into the conveyed material to prevent the screw from being jammed and causing damage to the screw machine.
      5. In use, always check the working status of each part of the screw machine, pay attention to whether the fastening parts are loose, if you find that the parts are loose, you should immediately tighten the screws to make them strong again.
      6. Special attention should be paid to whether the screw between the spiral tube and the connecting shaft is loose, dropped or cut off. If such a phenomenon is found, it should be stopped immediately and corrected.
      7. The cover of the screw shaft should not be removed when the machine is running to avoid accidents.
      8. Any abnormal phenomenon that occurs in the operation of the screw machine should be checked and eliminated, and no forced operation should be performed.
      9. The moving parts of the screw machine should always be lubricated.
      (1) Gasoline lubricating oil HQ-10 (GB485-81) should be used in the reducer of the driving device. Change the oil every 3-6 months.
      (2) Lithium-based grease is used in the bearing boxes at both ends of the screw machine, and 5 grams is injected every half month.
      (3) The screw bearing of the screw machine is selected from the M1 category, of which 80,000 bearings have been soaked with lubricating oil during assembly, and can usually be filled with less oil. Every 3-5 months, remove the hanging bearing body and the hanging shaft, and remove the seal Dip the suspension bearings and 80000 bearings in the melted grease, cool them together with the grease, and reassemble and use them. If the nylon seal is damaged, it should be replaced in time. Use it for one year and use the above method to maintain it again. Good effect.
      (4) The screw bearing of the screw machine is selected from the M2 category, with grease for each shift, and 5 grams of grease for each bearing pad. High-temperature materials should use ZNZ sodium-based grease (GB192-77). Self-lubricating bearing pads should be added. grease.
      Operating procedures
      1. All operators of screw conveyors and related personnel should be familiar with and abide by this regulation.
      2. Each screw conveyor should be designated by a special person for operation and maintenance. Other personnel must not start the screw conveyor without authorization.
      3. Preparations before driving:
      (1) Check the wiring and the switch is intact.
      (2) Check whether each fastener is loose.
      (3) Check whether each lubrication point is fully lubricated as specified.
      (4) Whether the screw is stuck.
      4. In order to prevent overload during starting, the screw conveyor must ensure no-load starting, that is, start when there is no material to be conveyed in the casing, and materials can be added after starting.
      5. The screw must stop after the unloading is clean, that is, stop the feeding first, and stop the operation after the material in the casing has been transported. To ensure the next no-load start.
      6. The feeding of the screw conveyor should be uniform, so as not to cause the material to accumulate at the hanging bearings.
      7. Do not mix hard large materials into the conveyed materials, so as to prevent the screw from being jammed during the feeding, which will cause the screw conveyor to be damaged.
      8. In use, always check the working status of each part of the screw conveyor, pay attention to whether the fasteners are loose.
      9. Special attention should be paid to whether the pin head of the screw shaft and the pin of the coupling shaft are loose, dropped or cut off. If this phenomenon is found, it should be stopped immediately to correct it.
      10. It is strictly prohibited to invert the tubular screw conveyor during use.
