Because the vibrating screen is affected by various environments and materials on site, coupled with the characteristics of the mechanical product itself (limited service life), it is inevitable to repair the vibrating screen. More importantly, the maintenance of the vibrating screen has a direct impact The quality of the products screened out, therefore, the accurate maintenance and maintenance of the vibrating screen is particularly important. Vibrating screen manufacturer Guosheng Machinery, teach you how to maintain and maintain the vibrating screen!
1. Maintenance of the vibrating screen before starting up:
① Check the vibrating screen and remove all kinds of debris that hinder the movement of the vibrating screen.
②Check whether there is enough lubricating oil at the lubrication points of the electric idea and the vibrating screen transmission mechanism. The movable bearing is lubricated with butter, and the oil is injected into the bearing, not more than two-thirds.
③The screen has sufficient tension and fixing force. The loose or uneven tension of the screen and the fluctuation of the screen surface will cause adverse effects and shorten the life of the screen.
④ All bolt connection parts must be screwed in place.
⑤Check the tension of the vibrating screen's drive belt to prevent slippage and affect the normal operation of the vibrating screen.
⑥Check the sealing strip and replace it if it is worn or defective.
⑦Check whether the connection of the feed box is loose, if the gap becomes larger, causing a collision, the equipment will be broken.
⑧ Check whether the wires, fuses and starting devices are normal. Start the vibrating screen to run for 2 to 3 minutes without load. During this period, it should be determined whether the vibrating screen is normal and whether the screen is jumping.
⑨Inspect the sieve support device, and replace it in time if the rubber pad or spring is damaged or excessively compressed.
2. Maintenance of vibrating screen during startup:
①The material should be fed to the screen surface along the moving direction of the material, and the material should be distributed evenly on the entire screen surface as far as possible, and overloading is not allowed.
②Check the fever degree of the main bearing, and the temperature rise is generally higher than the room temperature by 45~50℃.
③Check whether the vibration of the vibrating screen is stable. If there is abnormal vibration, impact or shaking of the fixed frame, it should be stopped in time and adjusted appropriately.
3. Maintenance of vibrating screen after work:
① The vibrating screen can only stop working after the feeder has finished feeding.
②Remove the dirt and oil on the vibrating screen, clean and repair the screen in time. When the screen is blocked, you can only hook it up with a hook, not a hammer.
4. Service life and inspection of vulnerable parts:
① The screen is a part of the vibrating screen that is easy to wear, and its service life varies with the structure type. The strip sieve is generally 5 to 6 months, the plate sieve is generally 2 to 3 months, and the screen is 3 to 4 weeks, while the fine mesh screen can only be used for a few days. The main feed end of the screen is worn. In order to extend the life of the screen, a protective device is first installed to prevent the falling material from impacting the screen.
②The bearings of the vibrating screen are usually replaced every 8 to 12 months, and the transmission belt is replaced every 2 to 3 months. The life of the spring is about 3 to 6 months, and the life of the screen frame is two years.
③Users should check regularly during use, find problems early, and maintain and deal with them in a timely manner. Only in this way can the vibrating screen have a long life, high efficiency, and high-quality work, so as to avoid big losses due to small mistakes, and achieve "spend small money to do big things", and reduce costs. Real place.
