What is the reason that vibrating screen spring shakes violently
Shaking screen spring is a common phenomenon
In general, there are a variety of reasons that cause the vibration screen to shake violently, such as the vibration screen vibrator produced by the direction of the excitation force deflection, offset; The spring damping system and different parts of the linear vibrating screen fail; The discounted vibrating screen is not placed on a horizontal surface, the screen surface can not maintain the radial clearance of the horizontal bearing; Bearing geometric accuracy; Bearing friction and lubrication; The outer ring is matched with the supporting hole.
Specifically, when the vibration of the stainless steel shaker eccentric vibration, if it is the reason for the shaker, you can increase the weight of the eccentric block, adjust the amplitude; If it is a vibration motor, the amplitude regulation depends on the eccentric block Angle at both ends of the shaft to change the size of the exciting force, the Angle is small, the exciting force becomes larger, the amplitude becomes larger; On the contrary, the Angle becomes larger, the exciting force becomes smaller, and the amplitude becomes smaller. Eccentric shaft vibrator, can increase or decrease the counterweight flywheel and belt wheel on the counterweight block, to increase or decrease the vibration screen machine amplitude.
When the shaker works, the centrifugal force generated by the eccentric weight makes the eccentric shaft bend, leading to the relative deflection of the inner ring and outer ring of the bearing. The eccentric will produce vibration caused by the frequency of rotation and each order frequency, so the inertia force and inertia force couple generated in the operation will cause the dynamic reaction and vibration of the bearing, destroy the smooth working state of the bearing and other parts, and produce high frequency vibration.
If the vibration force of the stainless steel vibrating screen is too large, it will lead to the bearing bearing very large radial force, resulting in strong vibration. Vibrating screen experts said that the higher the bearing accuracy, the smaller the vibration. When the raceway, especially in the rolling body surface corrugation, has a great impact on the vibration of the bearing, the gap between the rolling body and the cage and the rolling surface of the inner and outer ring, its relative motion will cause the vibration of the bearing.
Solution:
Check that the shaker frame is a regular rectangle, not a parallelogram; Check whether the spring support of the screen machine in the process of design and manufacturing can be in a unified degree, whether the spring stiffness is the same.
In addition, check whether the self-synchronization between the two vibrators is normal. Whether the phase angles adjusted by the primary and secondary bias blocks of the vibrator on both sides of the plate on the unified shaft are consistent, because it affects whether the exciting force is consistent.
There are some tips to prevent the shaker from vibrating violently. For example, each time the adjustment of the vibration motor at both ends of the eccentric block Angle is equal, and to the same side of the vibration motor. Check the rubber spring, there is no height difference between the springs, if there is, can be replaced by damaged parts to solve.
In addition, you can also check the balance of the linear vibrating screen equipment, and the screen surface in a horizontal position. The lifting Angle of the equipment can also be recalculated to maintain the same lifting tension

Packaging & Shipping
After you place the order and pay the deposit, we will start to arrange the production and contact the ocean freight transportation agency to reserve the position. Two days before the end of production, you need to complete the final payment. Then, we inform the ocean cargo transportation agent company that it is ready to come to the factory to pull the goods to the port. On the day of delivery, we will send the customer the factory video and pictures, and mark the corresponding English name of each product and product parts with a marker to prevent the customer from not knowing what each part is after receiving the goods. At the same time, we will put the English version of the product instructions in the cargo box. We generally select freight forwarders with preferential prices for customers to deliver goods for you. The shipping method can be FOB or CIF. You can also choose EXW, and then contact the goods agent company yourself.
