What is the cause of vibrating screen burning motor
In the process of using the vibrating screen, the motor burn is a more common problem, what are the reasons that can lead to the occurrence of such failures?
First, loose bolts cause motor burn. Loose bolts are one of the main reasons for motor burnout. The vibration force generated by the vibration motor at work will impact the anchor bolt two thousand times per minute. Moreover, the motor itself also takes part in vibration, most of which make the anchor bolt very easy to loosen. If one of the bolts is loose, it will cause the other bolts to loosen, which will cause breakage, thus burning the motor.
Method:
1, ensure the good contact of the motor floor in the floor area, so that several anchor bolts are evenly stressed;
2, often reinforce the anchor bolts;
3. Increase the anti-loose picking device. On material selection, the manager uses a vibration motor with shell and seat. Such a motor is processed in one time, so it can ensure the level. Shell seat allogeneic motor is processed and then assembled, so it is not easy to ensure the level, so that the force of the anchor bolt is not easy to be uniform, easy to cause the loosening and fracture of the anchor bolt.
Two, improper installation caused by motor burn; The upper and lower ends of the vibration motor are equipped with eccentric block, vertical or inclined installation requires the bearing axial bearing eccentric block gravity, if there is no plane bearing on the facade of the vibration motor will have an adverse effect on the bearing and shorten its service life.
Method:
1, choose vertical vibration motor (i.e. add plane bearing inside)
2, try to avoid vertical or inclined installation.
3. Improper adjustment of eccentric block causes motor burn; When adjusting the eccentric block, we must pay attention to its symmetry, that is to say, the eccentric block at both ends should correspond in pairs, if the wrong direction of the eccentric block at both ends is reversed, so that the vibration motor produces a space distortion, so that it works in an abnormal state, it will cause the motor to burn. Therefore, the center of gravity connection line of the eccentric block at both ends of the motor should be parallel to the rotating shaft, and can not be in a state.
Four, the protective cover seal is not strict, resulting in motor burn; Vibration motor mostly works in a large dust environment, in this case, if the protective cover seal is not strong enough, it is easy to enter the dust, causing the friction operation of the eccentric block, and then burn the motor. Therefore, we must strengthen the sealing of the protective cover and clean the dust inside the protective cover regularly

Technical parameters of linear vibrating screen
Guidance on use and maintenance of linear vibrating screen
1. The machine shall be equipped with electrical protection device.
2. At the initial operation stage of the machine, the anchor bolts shall be checked at least once a day to prevent looseness.
3. When the motor rotation direction does not meet the requirements, adjust the power supply phase sequence.
4. The motor shall be well lubricated, and lithium base grease (ZL-3) shall be added once every two weeks of operation. When refueling, an appropriate amount of lithium base grease shall be added through the oil cup. When sealed bearings are used, the motor is not equipped with oil cups.
5. After the machine has been running for 1500 hours, check the bearing and replace it immediately in case of serious damage.
6. When the machine is used again after being stopped for a long time, the insulation resistance should be measured, which should be greater than 0.5 megohm for 500 volt megger measurement.
Daily maintenance of linear vibrating screen
1. Before starting:
(1) Check whether the coarse mesh and fine mesh are damaged;
(2) Check whether the transportation support is removed.
2. At startup:
(1) Pay attention to whether there is abnormal noise;
(2) Whether the current is stable;
(3) Whether the vibration is abnormal.
3. After use: clean up after each use.
Regular maintenance of linear vibrating screen
Regularly check the coarse screen, fine screen and spring for fatigue and damage, and check whether all parts of the machine body are damaged due to vibration. The parts that need to be lubricated must be lubricated.
About Transportation
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.
