Common faults and solutions of vibrating feeder

Vibrating feeder is an essential equipment in the production of crushing sand It can evenly, regularly and continuously feed the massive and granular materials to the receiving device to avoid the blockage of the feeding port Electromagnetic vibration feeder and electric motor vibration feeder are common types of feeding equipment, they will inevitably encounter various problems in production Today, Xiaobian will tell you how to quickly resume production in case of the following common faults I failure analysis of the exciter bearing of the motor vibration feeder: the exciter will appear the phenomenon of bearing smoking and reddening in use As the eccentric block continuously impacts the bearing in the process of rotation and the site working environment is poor, the service life of the bearing is shorter than the normal service life Fault suggestion: it is suggested to use high-quality or imported bearings to extend service life In addition, bearing lubrication is particularly critical At ordinary times, it is necessary to strengthen lubrication or add automatic lubrication device II The vibration gap between the exciter core and armature of the electromagnetic vibration feeder is blocked Fault phenomenon: the power switch of the vibration feeder will trip during the use of the built-in electromagnetic feeder of the vibrator After the power is re supplied, the feeder will work with the phenomenon of fuse heating The current exceeds the standard, and the fuse will blow in a short time Check that the feeder control system and the contactor are all normal, but the power switch still trips frequently The vibration feeder The amplitude is basically zero during operation Fault analysis: according to the phenomenon analysis, it is mainly due to the material entering into the exciter, resulting in the vibration gap of the exciter being blocked If the sealing cover is opened for inspection, it will be found that the sealing silicone rubber is damaged, and sometimes the cooling hose of the vibration exciter is damaged, which will also cause this problem 3 Analysis of the leakage of the shell body of the electromagnetic vibration feeder: there are many connecting bolts for the sealing shell of the built-in vibration feeder of the vibrator, especially after the disassembly and maintenance, the sealing is difficult Fault suggestion: it can be solved by bolt fastening and pressure regulation at discharge IV leakage analysis of sealing silicone rubber plate of motor vibration feeder: there are many reasons for leakage of sealing silicone rubber plate, which are common at the bolt sealing connection In the process of vibration, bolt looseness, increase of bolt hole of rubber plate or increase of pressure at the discharge may lead to leakage of sealing connection of silicone rubber plate Fault suggestion: it can be solved by bolt fastening and pressure regulation at discharge The vibration head external electromagnetic vibration feeder is basically in maintenance free state in daily use Generally, the vibration coil temperature is checked regularly, and the rotary sealing valve is opened to check whether the inner plate of the material groove falls off during regular repair During the daily use of the motor type vibrating feeder, it is necessary to pay attention to the temperature change of the exciter bearing, strengthen the bearing lubrication, add an automatic oil filling device, and regularly conduct quantitative lubrication At ordinary times, it is necessary to pay attention to whether the seal at the rubber plate connection is good When conducting regular repair, it is necessary to open the upper port of the rotary seal valve to check the inner lining of the material groove and the vibration spring.
