A few days ago, a customer who had been working with our company for 3 years said that the linear vibrating screen he bought before suddenly appeared that the material transportation was not smooth, and the material was biased in a certain direction. problem.
In fact, this problem can be said to be a relatively good solution to the "old fault" compared to the linear vibrating screen. Next, I will use this opportunity to tell all the new and old customers about the cause of this problem, and to painstakingly sum up the 8 big gangs to help you solve this problem:
1. Insufficient linear vibrating screen feed = vibration motor installation problem
In a nutshell, the linear vibrating screen transports the material by the vibration source motor-vibration motor to push the material in a fixed direction of fixed-size excitation force. Therefore, if there is a poor material delivery situation. Basically, it can be judged that there is a problem in the installation angle of the vibration motor.
Under normal circumstances, as long as you are buying a linear vibrating screen with good design and consumables purchased by regular manufacturers, this problem will not occur in new machines, because regular manufacturers have professional technicians to carry out precise installation, test and adjustment. Service to avoid deviations in the direction of the excitation force, causing any unexpected situation such as abnormal operation of the linear vibrating screen;
2. Linear vibrating screen workload and working years are too long
Compared with the large linear vibrating screen, due to its heavy weight, if combined with large-scale screening labor for many years, some components of the linear vibrating screen body will appear due to such long-term repeated vibration and strong inertia. In the case of looseness, the loosening of these parts is likely to cause the change of the angle of the vibration motor at the same time, so that various problems have arisen, and it is necessary to mention the problem of regular linear vibration screen maintenance. At this time, as mentioned above, the angle of the vibration motor is carefully designed, so Jinjiashun does not recommend that the customer disassemble the machine to adjust it. This may be counterproductive. The correct method should be the manufacturer who purchased the linear vibrating screen. Regular manufacturers have professional post-maintenance personnel to go to the door for adjustment and maintenance;
3. Failure to feed evenly according to the instructions
If you have read the instructions of the linear vibrating screen in detail, you should know that there is a repeated requirement that the uniform feeding is because if the feeding is too much, it is easy to cause the screening accuracy to be unstable. And the material deviation caused by the material is large, and the problem of the material being biased to one side occurs;
4. The damper springs and other components of the linear vibrating screen body appear aging loose
In addition to the vibration motor to provide the main source of screening power for the linear vibrating screen, the linear vibrating screen damping spring, bouncing ball, sealing rubber ring, etc., which are present due to vibration damping, affect the vibrating force and straight line more or less. The water of the vibrating screen body is stable and stable. If there is a problem such as aging of a certain component, the unbalanced screen of the linear vibrating screen will be unstable, which will cause the problem of the deviation of the discharge direction. In severe cases, even sudden abnormal noise and straight lines will appear. The serious life of the vibrating screen is greatly reduced, so regular inspection and maintenance are particularly important;
5. The position of the center of gravity of the linear vibrating screen itself is unstable
Under normal circumstances, this problem does not exist in regular manufacturers, but now the market is chaotic, some customers think that price is everything, it is inevitable that some black-hearted manufacturers will take advantage of the inferior imitation linear vibrating screen at abnormal market prices, although the appearance is not the same. Second, but there is no technical content, so please keep your eyes open when you choose.
6. Vibration motor eccentric block position imbalance
The reason for this problem is consistent with the reasons stated in the previous point. The normal linear vibrating screen manufacturers who rely on technology to talk about quality will not only make these low-level mistakes, but Jinjiashun Company has unanimously promised to be single-time, lifetime maintenance, and important for large-scale machinery. It is a professional and stable after-sales service.
7. Damping springs have different materials and different stiffness
The same is the quality problem that is often talked about. The importance of the shock-absorbing spring to the linear vibrating screen is no less than that of the vibrating motor. He plays an important role in maintaining the stability of the linear vibrating screen and prolonging the life of the linear vibrating screen. Many prices are much lower than the price. Manufacturers with normal sales prices rely on accessories and consumables to cut corners to attract customers, and Zui eventually causes some customers to suffer heavy losses;
8. Screen box deformation
The screen box refers to a sieve surface that is fixed above the vibration motor and below the feed port and fixed by the screen frame and its surroundings. Under the normal operation of the linear vibrating screen, especially the large-scale, high-frequency linear vibrating screen, the screen frame needs the strong excitation force of the gravity and vibration motor from the large-scale screening material at the same time. If the strength is not enough, it is easy to be deformed. The problem of damage, large mining vibrating screens, especially need to pay attention to this problem. The strength of the screen box not only requires the high quality of the consumables, but also requires a unique welding process and additional stable design to be foolproof, and these are related to the manufacturer's strength and quality problems described in this article, and the small series is not lost.
In short, the linear vibrating screen is a general-purpose equipment for production. Buying it is to improve efficiency and create higher value. It is equivalent to an investment. It is really to polish your eyes, not be confused by appearance, and not be induced by low prices. I hope that this 8 large è¯€çª è§£å†³ 解决 直线 直线 直线 直线 直线 直线 直线 直线 直线 直线 直线 直线 直线 直线 直线 直线 直线!
