In the mining industry, the work task of the vibrating screen is still very important. It is necessary to screen the materials on the entire production line, and its processing capacity is large, and the screening effect is good. It is also indispensable screening equipment in many other industries. When we use vibrating screen equipment, of course we hope that the equipment can be used for a long time. This is also inseparable from the service life of the equipment, so how to extend the service life of the vibrating screen? Below, the vibrating screen manufacturer gave us the following specific introduction on how to extend the service life of the vibrating screen.
1. Install the vibrating screen correctly
The correct installation of the vibrating screen will help to extend the service life of the equipment. Before, we also specifically talked about how to install and debug the vibrating screen. One of the more important is the installation of the vibration motor. Heavier eccentric blocks are installed at both ends of the vibrating motor. During operation, we can control the excitation force by adjusting the number of eccentric blocks of the vibrating screen. However, due to the heavier eccentric blocks, such as vertical or inclined installation, The bearing has to bear the weight of the eccentric block in the axial direction, which will greatly affect the service life of the bearing. Therefore, when we do not require it, we generally recommend to choose a vertical vibration motor and try to avoid vertical or inclined installation.
2. Keep the vibrating screen stable
Maintain the stability of the vibrating screen equipment during use. Because the proportion of materials handled by the vibrating screen equipment is relatively large, and the work intensity is relatively high, various failure problems may occur during operation. If a failure problem occurs, it must be consuming the life of the vibrating screen. Therefore, the stability of the equipment must be maintained, which is also conducive to prolonging the service life.
3. Maintain the symmetrical balance of the eccentric block
When adjusting the eccentric blocks on both sides of the vibration motor, pay attention to the symmetry as much as possible, that is, the eccentric blocks at both ends should correspond to each other, or the connecting line of the eccentric blocks at both ends should be parallel to the axis of rotation and cannot be different planes. Otherwise, it is easy to make the vibrating screen unstable during operation, which may cause damage or burnout of the vibrating motor.
4. Dust the vibrating screen
Since the working environment of the vibrating screen is mostly harsh and dusty, if the vibrating screen equipment is operated in an open-air environment or in an environment where the protective cover is not tightly sealed, it is easy to get dust and cause the eccentric block to run by friction, thereby burning the motor. Therefore, in places where the working environment is harsh, firstly, increase the sealing of the protective cover, and secondly, frequently clean the dust inside the protective cover. This can also extend the service life of the vibrating screen.
5. Heat dissipation of the vibration motor
The bearing or main parts of the vibration motor are easily burned or burned when the temperature is too high under operation or abnormal operation. We can often vibrate the surface of the motor by vibrating the dust on the motor surface to make it work in good conditions. When working in a large environment, consider subtracting the heat dissipation ribs on the surface of the case. In addition, the equipment can be shut down to dissipate heat after operation.
6. The vibrating screen feeds uniformly
The vibrating screen is a continuous operation equipment, so the vibrating screen equipment needs continuous feeding. If you use too much during feeding, materials will accumulate on the vibrating screen, which will cause the vibrating screen to loosen and reduce fatigue. Due to the high screening efficiency, the equipment itself also increases the work load and damages the vibrating motor, so it is uniform Ground conveying vibrating screen is very important.
7. The material on the sieve surface is sieved cleanly
When the equipment stops production, the material on the screen surface should be sieved clean. After the production is completed, the screen surface materials should be completely screened before the shutdown is performed. This is because the residual materials in the screen surface and the screen body will corrode the linear screen frame and the screen and affect the service life.
8. Regular maintenance of the vibrating screen
Regular maintenance and maintenance of the vibrating screen is also very conducive to prolonging the service life of the vibrating screen. General maintenance is divided into weekly inspection, monthly inspection and annual inspection. The annual inspection is to overhaul the vibrating screen and disassemble the vibrating screen for cleaning. Maintenance also includes regular maintenance and daily maintenance. Regularly check whether the coarse mesh, fine mesh and spring are fatigued and damaged, and whether various parts of the fuselage are damaged due to vibration, and the parts that need to be lubricated must be lubricated.
9. Choose high-quality vibrating screen
The quality of the vibrating screen directly determines the service life of the screen. Many people buy poor quality vibrating screens at increasingly cheaper prices. This is not conducive to production. It is also possible that some unconscionable manufacturers will install bad parts on other vibrating screen equipment and sell them at a low price. This will not only have a low equipment life, but also affect production and safety. There are great negative effects.
10. Handover work must be in place
The production of some enterprises is assembly line operation, and the screening machine works 24 hours a day. This requires the operator to make a record of the shift during the shift, record the output of the screening machine during use, the problems encountered during use and the solutions Wait. This can provide a good review for the next shift and targeted maintenance and observation.
The above is the answer to how to extend the service life of the vibrating screen. In general, there are correct installation of the vibrating screen, maintaining the stability of the vibrating screen, maintaining the symmetrical balance of the eccentric mass, and removing dust from the vibrating screen. The ten measures introduced can effectively extend the service life of the vibrating screen.
