The linear vibrating screen is driven by double exciters. When the two exciters are rotated synchronously and in opposite directions, the exciting forces generated by the eccentric blocks cancel each other in the direction parallel to the motor axis, and in the direction perpendicular to the motor axis The stack is a resultant force, so the motion trajectory of the screen machine is a straight line. The two motor shafts have an inclination angle relative to the screen surface. Under the combined force of the exciting force and the self-gravity of the material, the material is thrown up on the screen surface and moves forward in a straight line, so as to achieve the purpose of screening and grading the material.
Can be used to automate operations in the assembly line. It has the characteristics of low energy consumption, high efficiency, simple structure, easy maintenance, and fully enclosed structure without dust spillage. The high sieving mesh number is 400 meshes, which can screen out 7 kinds of materials with different particle sizes. In the daily use of the linear vibrating screen, it is inevitable that some damage will not occur. The following vibrating screen manufacturers will introduce the common faults and solutions of the linear vibrating screen in detail.
1. Pipe beam fracture
If the wall of the tube beam is too thin, it may cause fracture. In this case, the same type of thick-walled tube or a larger type of tube beam should be used. But it should not be too large or too thick, because this will increase the vibration quality of the sieve and bring about many problems; the connection of each sieve plate of the dehydration and de-intermediation screen must have horizontal and vertical layers. If there is no vertical layer, water The pipe beam will leak from the gap between the screens and the pipe beam will be easily broken at the flushing place; the wider the screen, the easier the pipe beam will be broken.
2. Beam fracture
The fracture of the beam is mostly due to the long working time at the critical frequency, the relaxation of a large number of high-strength bolts that fasten the side plates, the severe deformation of the spring, and the difference between the left and right heights. The beam is broken. At this time, the damaged structural parts and beams should be replaced, the bolts should be tightened, and the quality of the eccentric block should be adjusted.
3. The screen frame is broken
The screen frame is prone to breakage due to trembling. The best way to solve this problem is to thicken the side plate, or add an additional plate to the local area of the side plate near the exciter to enhance the rigidity of the entire screen frame.
4. The discharge port is broken
Since the vibrating screen is generally made of non-standard products, the size required by different customers is different, and some require the discharge port to be extended forward or downward, so that the discharge port will be broken relatively slightly more. If it is the initial design, the plate thickness or ribs can be strengthened. In case of accidental breakage, the material quality can be checked.
In addition, check whether the parameters of the vibrating screen are correct. In addition, in the feeding process, it is necessary to avoid excessive feeding of the vibrating screen at one time, and the screen can be basically used completely. The outlet of the vibrating screen is discharged, and the excessive weight backlog will also cause the breakage of the discharge port of the vibrating screen.
If the linear vibrating screen fails, you can refer to the above methods to solve it, but if your problem has not been solved, please contact the manufacturer in time for after-sales service, and ask professionals to repair it in time, so as not to reduce your work efficiency.
