The bundle puller, as a kind of precision equipment, inevitably encounters various problems during the long-term use process. In order to ensure the normal operation of the equipment and extend its service life, it is very necessary to detect and troubleshoot faults in time. This article will introduce in detail from multiple perspectives how to determine whether the bundle puller is damaged.

1. Visual inspection
   · Hydraulic oil leakage: Check whether there is oil leakage in the hydraulic system, and the parts such as the hydraulic cylinder and pipe joint are the key inspection objects.
   · Wear marks: Check whether the traction device, guide device and other components have obvious wear marks, such as scratches and deformations.
   · Cracks and deformations: Check whether the equipment body has cracks, deformations, etc.
   · Loose connections: Check whether each connection part is loose, including pipeline connections and electrical connections.
2. Function check
   · Driving device: Check whether the driving device can start and stop normally, whether the operation is stable, and whether there is an abnormal sound.
   · Traction force: Check whether the extractor can generate sufficient traction force to smoothly extract the bundle tube.
   · Control system: Check whether the control system can accurately control the extraction speed, pressure and other parameters.
   · Guide device: Check whether the guide device can ensure that the bundle tube maintains the correct direction during the extraction process.
3. Performance index check
   · Extraction force: By measuring the extraction force of the equipment and comparing it with the rated extraction force of the equipment, judge whether its performance has declined.
   · Extraction speed: Measure the extraction speed of the equipment and compare it with the rated speed of the equipment, judge whether its performance has declined.
   · Hydraulic oil pressure: Measure the pressure of the hydraulic system and compare it with the rated pressure of the equipment, judge whether the hydraulic system is normal.
4. Abnormal sound
   · Abnormal noise: Pay attention to whether there is an abnormal noise during the operation of the equipment, such as metal rubbing sound, abnormal noise of the pump, etc., which may all be signs of faults.

Fault code
· Display screen: If the equipment is equipped with a display screen, pay attention to whether there is a fault code display.
Common faults and cause analysis
· Hydraulic system faults: Hydraulic oil leakage, hydraulic pump damage, hydraulic valve faults, etc.
· Mechanical faults: Traction device wear, guide device deformation, transmission component damage, etc.
· Electrical faults: Motor burnout, control system faults, etc.
How to prevent faults
· Regular maintenance: Regularly check, clean and lubricate the equipment, and replace worn parts.
· Reasonable use: Operate according to the requirements of the equipment manual, and avoid overloading operation.
· Environmental protection: Keep the environment around the equipment clean to avoid dust and debris from entering the equipment interior.
Summary

By inspecting the appearance, function, performance index and other aspects of the bundle puller, faults existing in the equipment can be discovered in time, and corresponding measures can be taken for maintenance or replacement. Regular maintenance of the equipment can effectively extend the service life of the equipment and reduce the probability of faults.
