PP PE plastic pelletizing machine is one of the key pieces of equipment in plastic recycling, and its main motor is the core component that drives the whole granulation process. However, due to the long time high-load operation, the main motor has the possibility of excessive torque failure.
This article will analyze the reasons for the failure of the PP PE plastiki pelletizing mashine motor, and put forward measures to solve the problem, aiming to protect the stable operation and production efficiency of the PP PE plastic pelletizing machine.
PP PE plastic pelletizing machine main motor failure causes
- Oil lubrication system failure: the lubricating oil system of the main motor of the PP PE plastic pelletizing machine is the key to guaranteeing its normal operation. If the lubrication system fails, it may lead to a lack of lubrication of the motor bearings, thus damaging the motor.
- Poor alignment of the output shaft and gearbox access shaft: the output shaft of the main motor and the input shaft of the gearbox must be kept in good alignment, otherwise, it will lead to uneven force on the motor and accelerate the wear of bearings.
- Motor and clutch vibration: long-term high-load operation will easily lead to excessive vibration of the motor and clutch, increasing the degree of wear of the motor bearings.
- Excessive feeding load or poor melting of materials: if the feeding load of the PP PE plastic pelletizing machine is too large or the materials can not be fully melted, it will lead to excessive force on the main motor, making it overloaded and thus damaging the motor.
Measures to solve faults
In order to solve the problem of main motor failure of PP PE plastic pelletizing machine, the following measures should be implemented.
Regularly check the lubricating oil system
Regularly check the working condition of the lubricating oil system, including the quality of the lubricating oil, the oil level, the filter screen and so on. Replace and clean the lubricating oil in time to ensure that the motor bearings are well lubricated.
Measure the main motor bearings
Use the vibration measuring instrument and infrared thermometer to measure the main motor bearing of the plastic extruder pellets machine on a regular basis and form a trend graph. Once the trend value is found to be exceeded, the main motor idling current value or power value should be measured immediately to determine whether it is necessary to replace the bearings to prevent motor damage.
Control feeding load and material melting
Reasonably control the feeding load of the plastic extruder pellets machine to avoid overloading the main motor due to excessive load. At the same time, ensure that the material can be fully melted to reduce the main motor due to poor material melting and overload.
Regular maintenance and upkeep
Regular maintenance and repair of the PP PE plastic pelletizing machine, clean the inside and outside of the equipment, check the wear and tear of each part, and timely replacement of parts that are badly worn to ensure that the PP PE plastic pelletizing machine is always in good working condition.
The main motor of PP PE plastiki pelletizing mashine is the core component of the whole equipment, and its stable operation directly affects the production efficiency and product quality.
By regularly checking the lubricating oil system, measuring the main motor bearings, and reasonably controlling the feeding load and material melting, we can effectively prevent the occurrence of the main motor failure and guarantee the long-term stable operation of the plastic extruder pellets machine.
