Although the vibrating hopper is safe to operate, reliable to use, easy to operate and simple to maintain, practice has shown that once a fault occurs, it will be damaged in a short period of time if it is shut down and eliminated in time. Therefore, operators and maintenance personnel need to master the performance of the vibrating hopper, strictly implement operating procedures, and perform timely maintenance to ensure long-term normal operation of the vibrating hopper.
. Precautions before starting up the vibrating hopper
. Check whether there are factors affecting vibration around the vibrating hopper. Once found, they should be eliminated immediately.
b. Check whether the condition of the vibrating feed hopper itself is normal: whether all nuts are tightened (for important components, such as the eccentric block group, adjustable eccentric block fastening nut, vibrator base fastening nut, spring fastening nut, etc. , is particularly important) Whether the bearing lubrication is good, whether the vibration isolation hanging device or supporting device is normal, whether the sealing device (should not be filled with material) is sealed and can move freely, whether the welds, etc. are cracked, etc.
Check the integrity, sensitivity and reliability of various control devices.
. Check whether the conditions in the discharge port and silo meet the requirements.
. Things to note when starting up the vibrating hopper
. Whether the startup is normal. Sometimes an ammeter is used to check whether the starting current is within the allowable range.
b. If there is any abnormal noise or vibration after turning on the machine, observe the amplitude indicator to see if the amplitude is normal and stable.
Whether the feeding state is uniform, continuous, loose and accurate.
3. Precautions when operating the vibrating hopper
Observe whether the vibration is normal.
b. Observe whether the feeding is stable.
Check whether the nut is loose and whether there is any abnormal noise.
. Check whether the motor and bearings exceed the allowable temperature rise.
.Check the temperature rise of the rubber spring to see if it is too high.
.Check the sealing effect of the sealing device of the vibrating hopper, whether there is overflow and material plugging, and whether it affects the vibration
