The torque of main motor of bio organic fertilizer extruder is too high
Fault analysis: oil lubrication system failure, poor alignment between output shaft and gearbox shaft of main motor of drum granulator, vibration of motor and clutch will damage main motor bearing, causing excessive torque. In addition, too much feed load or poor material melting can cause the main motor torque too high.
Troubleshooting measures: regularly check and clean the lubricating oil system of fertilizer extrusion granulator, measure the bearing of main motor with vibration measuring instrument and infrared thermometer to form trend diagram. If the trend value is exceeded, judge whether the idle current value or power value of the main motor exceeds the specified value and whether the bearing should be replaced.
Check the alignment of the output shaft of main motor and the input shaft of gearbox regularly. Alignment must be checked after the first drive or three months after the bearing is replaced. Conduct electrical test and inspection to determine the causes of rotor unbalance; Test the vibration speed of clutch, if it exceeds the specified value, readjust the dynamic balance.
Regularly check the heating and cooling system of the cylinder to ensure that the material is heated evenly and fully melted. If the power curve and melt pressure curve of main motor increase at the start-up of extruder, it means that the feeding quantity of the feeding system is too large in a moment, and the feeding quantity should be reduced.
The development and application of bio organic fertilizer can not only create conditions for the development of green agriculture and organic agriculture, but also "turn waste into treasure", and realize the utilization of resources. It has higher economic, ecological and social benefits.
It is a powerful guarantee for the sustainable development of agriculture. In the future, bio organic fertilizer will become a hot spot in the production and consumption of agricultural resources in fertilizer industry, and it has a broad development prospect.
