The manufacturer of the stranding machine stated that any equipment has a rated operating range, and if it exceeds the rated range, the equipment will experience abnormalities. Under the influence of excessive fluctuations in the power grid, the controller, frequency converter, and sensors of the stranding machine will experience abnormalities, mainly manifested as the controller not outputting signals and the frequency converter emitting overvoltage or undervoltage alarms. For power grid inspection, an oscilloscope can be used to check the voltage waveform of the power grid. If excessive fluctuations in the power grid are found, corresponding measures should be taken to avoid equipment abnormalities. The conventional processing method is to add an AC voltage regulator to the power input of the stranding machine.
The manufacturer of the stranding machine stated that after the winding machine controller is powered on, a system self check will be conducted to check whether the peripheral sensor signal is normal. Whether it can start normally depends on the signal input of the winding machine system position sensor and the buttons on the operation panel. When the sensor signal is abnormal, the controller will display an error code and need to use detection tools to determine the signal of the external button. After troubleshooting, the controller can start normally.
The manufacturer of the stranding machine stated that the stranding machine is an electrical equipment that integrates electrical control and precision machinery, therefore it has high requirements for the environment and supporting power supply. Due to the load characteristics of factory power supply, there are a series of impacts and interferences, among which electromagnetic interference is a common type. The stranding machine often shuts down frequently due to its interference, and the set parameters are not saved or confused, which has no impact on the equipment in a short period of time. However, the winch has been subjected to excessive power grid interference pulses for a long time, leading to premature aging and failure of internal components in the controller. Generally speaking, this problem can be solved by separately supplying power to the stranding machine or adding capacitance.
Technical maintenance of the stranding machine:
1. The host adopts oil lubrication and natural circulation cooling, effectively extending the service life of the spindle bearings. The wire passing system adopts a new structure, where the wire passes directly from the guide wheel of the spindle to the bow belt, reducing scratches and strand jumping caused by the failure of the corner guide wheel on the aluminum plate- Stranding machine
2. The manufacturer of the stranding machine stated that the entire machine adopts synchronous belt transmission, and there are no lubrication points inside the machine to keep the machine clean. The stranding wire is oil-free and suitable for conductor stranding of various wires with high surface cleanliness requirements.
3. Simply replace one take-up wheel to adjust the twisting distance, and simply pull the reversing lever to adjust the twisting direction. The operation is simple and clear, reducing the operator's error rate and work intensity. The bearings of the entire machine are made of well-known Japanese brands, and the bow belt is made of new materials with good flexibility. It can avoid jumping due to vibration during high-speed operation. Frequency converters, PLCs, magnetic particle clutches, electromagnetic brakes, and hydraulic jacks are all imported products to reduce failure rates and maintenance costs.
4. The speed of the spindle can reach 3000 revolutions per minute.
5. Automatic tension control: When winding, after the wire is fully wound from the bottom of the drum, the winding tension needs to be continuously increased. This machine can automatically track and adjust the take-up tension; Make the tension of the entire winding line uniform, and at the same time, this machine can adjust the tension without stopping the machine- Stranding machine
6. This machine is equipped with three compression devices to ensure the roundness of stranded wires and reduce the loss of insulation materials.
