Now, vibratory separator has been widely used in all walks of life, industrial production and people's life are inseparable from vibratory separator.However, the vibratory separator may be threatened by various potential damages during its operation.Below we simply understand the vibratory separator of a few common failures and processing methods. 1. If the vibratory separator cannot be started or the amplitude is too small, electricity should be considered first
There is no barrier on the air, motor damage, or circuit components are not damaged, but also
If there is no problem in these three respects, then it must be mechanical
Check, whether the material on the screen piled up too much, if so, should be removed immediately.Because the heap
Too much material will directly affect the amplitude of the vibratory separator.If the coupling bolt on the vibrator falls off and the grease thickens and agglomerates, then the vibrator can be cleaned and repaired, and the position of the weight block or the auxiliary eccentricity block of the eccentric shaft can be adjusted appropriately.
2. The material flow on the screen surface is abnormal. This problem may be due to insufficient rigidity of the screen box and the existence of critical frequency, indicating that the connection bolt has loosened or even reached the degree of overall loosening and needs to be tightened immediately.The second is the screen box horizontal did not find the correct, from the support foot spring itself to find the problem, the spring or the pad or change the size of the support, there may be screen mesh damage, as long as the replacement screen can be.If the screen box is not rigid enough and the horizontal level is not properly determined, the beam will break, and the material flow will be abnormal if it is still in operation.There may be improper operation, that is, the uneven feeding is one of the reasons.
3. Poor screening quality. The reason for this problem is that there are many responsibilities for improper operation.
Uneven feeding, the responsibility of the machine may not be tight on both sides of the screen, such as mechanical problems are solved, can come for a period of time to reverse rotation, in order to improve the screening quality.
4. In normal operation, the rotation of the vibratory separator is relatively slow, and the bearing is hot, which indicates that the usual maintenance is not up to date, and the bearing is short of grease;So the daily maintenance of the vibratory separator is also very important.If the bearing is newly added grease, it may be due to grease quality or overfilling. The poor quality of grease causes the bearing to block the labyrinth seal plug, so the quality of the grease is very important.
5. If the noise of vibratory separator is too large during the working period, it may be the bearing damage, bolts loose, spring damage, except the bolts can be tightened, the other two conditions should be replaced parts.
It is difficult to screen the materials with static electricity Causes of motor burning of vibratory separator
In fact, there are many reasons for motor burning: loose anchor bolts, improper installation, eccentricity
The adjustment of the block, the sealing of the protective cover is not strict, the ambient temperature, the ambient temperature and so on are all the reasons that cause the vibratory separator motor to burn down easily.How can you avoid it?Here I have summarized a few points that I hope will be helpful to you if you use a vibratory separator.
As for the reason of loose anchor bolts, we can often strengthen the anchor bolts;
(2) Increase the anti-loose device;
(3) to ensure the good contact between the foot and the motor floor, so that a few anchor bolts uniform stress;During installation, because both ends of the vibration motor are equipped with heavy eccentric blocks, such as vertical or inclined installation, the bearing axial bearing should bear the gravity of eccentric blocks.If there is no special device in the vibration motor, it will have a bad effect on the bearing, thus shortening the service life. Therefore, we should try to avoid vertical or oblique installation;The adjustment of the eccentric block, sometimes we will mistakenly adjust the direction of the eccentric block at both ends, so that the vibration motor produces a space torque, so that the vibration motor in the abnormal state of work, and then cause the burn out.Therefore, when adjusting the eccentric block, it is necessary to pay attention to its symmetry. The center of gravity connection line of the eccentric block at both ends should be parallel to the axis of rotation, and should not be in a different plane state.The sealing problem of the protective cover, the working environment of the vibration motor is very bad, and the dust is big. If the protective cover is not tightly sealed, it is easy to enter the dust, causing the friction of the eccentric block, thus burning the motor.So in the poor working environment, to increase the sealing of the protective cover, but also often clean the dust inside the protective cover;Ambient temperature The temperature of conveying materials should not be too high.Because the vibration motor and equipment are an integral whole, if the temperature of materials transported by the equipment is too high, it is easy to cause the temperature of the ground and chassis of the vibration motor to increase, causing heat dissipation difficulties and thus burning the motor.Therefore, on the premise of not affecting the vibratory separator work, the vibration motor should be kept away from high temperature materials as far as possible;And try to reduce the temperature of the material.In fact, the causes of the vibratory separator vibration motor is easy to burn out are more than these, but as long as we know, usually should pay attention to what aspects to avoid wrong operation, will extend the service life of the vibratory separator vibration motor.
We EXCT production vibration separator in front of the factory will be through a series of product quality detection, including temperature, amplitude, screening efficiency, screen hook, motor, spring, and will give a series of random fragile parts and installation kit, containing spring, sealing strip, bounce the ball, spring seat, hammers, wrenches, etc., can let you after the receipt of the goods according to the need for installation and commissioning.Our vibratory separator has the advantages of high screening efficiency, low noise, low failure rate, simple operation, stable operation, safety and reliability.
