As a kind of equipment widely used in the pipeline processing industry, the main function of the elbow machine is to bend the pipe in order to facilitate the installation and connection in practical applications. Whether in construction, oil, gas and other industries, elbow machines play an extremely important role. However, with the increase of use time, the equipment will inevitably have various failures, affecting production efficiency and increasing maintenance costs. Therefore, mastering the troubleshooting method of the elbow machine is of great significance for improving the efficiency of the equipment and prolonging its service life.
1, the basic structure and working principle of the elbow machine
1.1 Basic structure
The main components of the elbow machine include:
- ** Rack ** : Bearing all components to ensure the stability and strength of the equipment.
- ** Power system ** : Usually composed of motor, reducer, etc., to provide the power required for equipment operation.
- ** Pipe bending device ** : including pipe bending wheel, support rod, etc., for the actual pipe bending operation.
- ** Control system ** : Generally controlled by PLC, responsible for equipment operating status monitoring and parameter setting.
- ** Cooling system ** : in high load operation, prevent equipment overheating, extend the service life.
### 1.2 Working principle
The working principle of the bending machine is mainly to bend the pipe under the action of the bending wheel by applying a certain force. The motor drives the reducer, which in turn drives the bending wheel to rotate. During the bending process of the pipe, the control system monitors the bending Angle and speed in real time to ensure the quality and accuracy of the elbow.
Second, the necessity of troubleshooting
Equipment failure will cause production line shutdown, but also lead to economic losses and stability risks. Therefore, regular troubleshooting is an important measure to maintain the normal operation of the equipment. The significance of troubleshooting is mainly reflected in the following aspects:
1. ** Improve production efficiency ** : Timely detection and handling of faults, reduce downtime, improve production efficiency.
2. ** Reduce maintenance costs ** : Through regular inspections, potential problems can be found early to avoid high costs caused by large-scale maintenance.
3. Ensure stability ** : Equipment failure may lead to stability accidents, regular investigation can effectively reduce risks and ensure the safety of workers.
4. ** Extend the life of the equipment ** : Reasonable maintenance and troubleshooting can extend the service life of the equipment and improve the return on investment.

2. ** Check program Settings ** : Confirm whether the program parameters are correctly set and whether there is an incorrect operation.
3. ** Cable connection Check ** : Check whether the cable connection of the control system is good, whether there is wear or short circuit phenomenon.
4. ** Replace the control module ** : If the fault cannot be rectified, consider replacing the control module for further testing.
3.3 The pipe bending device is faulty
#### 3.3.1 Fault Symptom
- The bending accuracy does not meet the requirements
- Stall occurs during pipe bending
- The bending wheel is badly worn
#### 3.3.2 Troubleshooting Method
1. ** Measuring bending Angle ** : Use Angle measuring instrument to confirm whether the actual bending Angle of the elbow meets the design requirements.
2. ** Check the bending wheel ** : Check the wear of the bending wheel and replace it if necessary.
3. ** Lubrication check ** : Check whether the bending device lacks lubrication and add lubricating oil in time.
4. ** Torque test ** : Measure the torque of the bending device to ensure that it is within the design range to avoid stalling due to insufficient torque.
3.4 Mechanical structure failure
#### 3.4.1 Fault Symptom
- The rack is deformed
- The connection is loose
- Abnormal vibration of elbow machine
#### 3.4.2 Troubleshooting Method
1. ** Appearance inspection ** : Regularly check the frame and the connecting parts to confirm that there is no obvious deformation or crack.
2. ** Fastener inspection ** : Check whether the fasteners are loose, and strengthen them if necessary.
3. ** Vibration test ** : Use vibration test instrument to detect the running state of the machine and determine whether there is abnormal vibration.
4. ** Balance check ** : Ensure the balance of the elbow machine to avoid damage caused by imbalance.
4. Precautions for troubleshooting
1. ** Regular maintenance and maintenance ** : Through regular maintenance and maintenance, you can reduce the probability of failure and improve the stability of the equipment.
2. ** Training operators ** : Operators should be trained to master the basic principle of the elbow machine and troubleshooting methods.
3. ** Use regular parts ** : When the equipment is repaired and replaced, the regular parts provided by the manufacturer should be used to ensure the stability of the equipment performance.
4. ** Record fault data ** : Establish fault files to record the phenomenon, processing process and results of each fault, which is convenient for subsequent analysis and improvement.
## Five, summary
