In modern industrial production, in order to save raw materials, various equipment in various industries emerge in an endless stream. As an important equipment for processing residual materials, pressing and reusing, it is inevitable that various wear and aging will occur during use. Important working components in the briquetting machine the roller skin is often replaced after being worn out.
The roller skin is a cylindrical member with balls and sockets dug on the surface of the roller core of the briquetting machine. Normally, the pressing of materials depends on hydraulic drive rollers, which are formed by the balls of the roller skin, as a briquetting mechanism that is very easy to wear. Frequent replacement is unacceptable to the operators, but the worn out briquetting machine roll skin cannot meet the production requirements, and it is impossible to do it without replacement. Therefore, it is very important to maintain the roll skin during use. The specific briquetting machine What is the maintenance method of the roller skin?
1. The roller skin of the briquetting machine should be installed correctly
There are four ways to install the roller skin of the briquetting machine. Different briquetting machines use different methods, but the installation standards are the same. What’s more about production, the shape of the ball socket on the roller skin must be aligned, otherwise the briquetting machine will not produce the ball, loose balls, and the ball is not real; at the same time, because the roller skin and the ball socket are not aligned, the ball will still be the ball. The edges of the sockets wear out, and the rollers must be replaced after a long time.
2. Protect the briquetting machine before working
The commonly used steel for casting briquetting machine roll skin is 65 manganese alloy, and the commonly used steel for forging briquetting machine roll skin is 92 chromium molybdenum. Our company uses higher-level forgings—bearing steel. Casting roller skins are relatively non-wearing, but the advantage lies in their low cost. Some operators are not bad for money, and it’s not a big deal to replace the roller skins frequently, but for the operators who use forged roller skins, the more durable the roller skin is, the better. It is better not to be replaced, but the maintenance method of the roller skin of the briquetting machine is not allowed.
After the roller skin is installed correctly, if you want to reduce the degree of wear of the roller skin, you must take certain protective measures before the equipment is working. Magnets must be installed on the feeding belt conveyor to prevent the harder metal from entering the roller skin and causing the roller skin to stick. In the process of material transportation, the staff must pick out the stones in time, and ensure that the particle size of the material is below 3 mm, so that while ensuring the service life of the roller skin, it can also ensure that there will be no problems in the material forming; Previously, the staff had to check the briquetting machine rolls to see if there was any looseness or deviation. If this phenomenon occurs, continuing to work will easily cause the roll to break, and the loss is more than the roll skin.
3. Ensure the status of safe production equipment when briquetting machine is working
The hydraulic protection device is one of the cores of the briquetting machine. While providing the required production pressure for the rolls, it can also cause excessive feed between the rolls or metal blocks when the piston rod of the hydraulic cylinder is pressed and overloaded. The resulting hydraulic pump shutdown and pressure change make the accumulator play a buffer role, and at the same time the overflow valve opens to return the oil to move the piston rod, thereby increasing the gap between the two rolls. This series of actions makes the hard objects pass through the rolls to ensure the roll No more serious damage.
If you want the hydraulic protection device to play its due role, it is necessary to carry out normal maintenance work. During work, the pressure supply of the hydraulic device should be reasonable, the stroke should not be excessive, and the temperature of the hydraulic oil should not be too high or high. In normal times, the hydraulic oil should be filtered regularly. If there are impurities in the oil, it is easy to damage the seals. , Causing malfunction, and even scratches on the master cylinder.
4. Clean up in time after the work is completed
A clean production environment can ensure that employees have a positive working attitude at work. They must perform sanitary cleaning after daily work. In addition to cleaning the ground, cleaning the equipment is also one of the maintenance methods for the roller skin of the briquetting machine. There is too much dust. It is easy to cause dust to accumulate in the moving parts of the equipment and the exposed parts of the bearing. If it is not cleaned for a long time, it will affect the safety and normal production, and also cause damage to the equipment; some materials pressed by the briquetting machine are corrosive. When the equipment is cleaning, the remaining materials on the roller skin and in the ball socket should be cleaned to prevent the roller skin from being corroded for a long time, which will cause damage to the roller skin.
