The main function of the screw conveyor
is to convey materials. The planning of the screw conveyor
depends on the parameters of the screw conveyor
, and these parameters depend on the materials to be transported. The spiral conveyor designed in this way is the most suitable for the transportation of materials. To achieve the maximum benefit of the screw conveyor
. The conveying capacity of the conveying equipment is one of the most important targets for measuring the production efficiency of the screw conveyor
. It is usually formulated according to the operating requirements, but it is closely related to its parameters. When conveying materials, the cross section occupied by the shaft diameter of the screw conveyor
etc. Both have a great impact, and the rotation of the spiral has a very large impact on the amount of transport. Generally speaking, the screw shaft rotates at a high speed so that the production of the conveyor can be improved. If the rotation speed is too small, the conveyor capacity is reduced, but the rotation speed should not be too high. When the speed exceeds a certain level limit, the material will If it is too large, it will be thrown outward, making it impossible to transport. The speed of the screw conveyor must be set to a limited amount, and it cannot exceed a certain limit. Solenoid pulse valve
Common faults during screw conveyor
The layout of the screw conveyor
is simple, and there are fewer problems during the normal production process. There are two main aspects:
(1) Reason for the suspension of rotation of the screw shaft: The amount of material to be transported is too large, and the material cannot pass through the central hanging bearing smoothly. The resistance of the material at the central bearing is too large, which will cause the motor to be overloaded and the motor will be burned in severe cases. Therefore, the material accumulated in the conveyor must be sorted, and the viscosity of the material to be conveyed must not be too large.
(2) The temperature of the reducer bearing rises too fast after driving, there is abnormal noise, and it is accompanied by the vibration of the motor and the reducer. In this case, you should stop in time and find the reasons in the following aspects:
a. The bearing temperature at the output shaft of the reducer is high, and the temperature at the input shaft is normal. This is because the centerline of the spiral shaft is deviated or the bearing at the output shaft of the reducer is burned, and the fixing of the first and last bearing seats is loose. Need to loosen the coupling between the reducer output shaft and the screw shaft, and calibrate the device from scratch.
b. The temperature of the reducer output bearing is normal, and the temperature at the shaft of the shaft is high. This is because the motor fixing bolts are loose or the bearing at the reducer output shaft is burned. You need to loosen the coupling between the reducer shaft and the motor, and calibrate the device from scratch.
c. The temperature at the output and input bearings of the reducer is high. This is because the reducer fixing bolts are loose or the bearings on both ends of the reducer are burned. It is necessary to loosen the couplings on both sides of the reducer and calibrate the device from scratch.
d. There is a cause of abnormal noise at the open gear transmission: the first and last bearing seats are loosened or shifted, which causes the transmission gear distance to change, which needs to be adjusted from the beginning; the transmission or bracket has loosened or shifted to make the transmission Gear distance seizure changes.
