Brief discussion on common electrical faults of winding machine manufacturers

Faults caused by the quality problems of electrical components themselves often appear after the equipment has been used for a period of time without any early warning. These faults are often caused by the quality of the products of the winding machine manufacturers. During the normal use of winding machine, users should pay close attention to all kinds of operating conditions of the equipment, whether there is abnormal noise, smell and other abnormal conditions, and if problems are found early, the faults can be controlled in a smaller range.

Winding machine manufacturer's winding machine is an electrical equipment integrating electrical control and precision machinery, so it requires high 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 common. The winding machine often stops frequently due to its interference, and the set parameters are not saved or confused, which has no influence on the equipment in a short time. However, the winding machine has been subjected to excessive power grid interference pulse for a long time, which makes the components inside the controller prematurely age and fail.

In general, this problem can be solved by supplying power to the winding machine alone or installing capacitors.

Common electrical executive components in winding machine include controller, frequency converter, spindle motor, stepping motor, electromagnetic brake, solenoid valve, etc. These are also the core electrical components of winding machine manufacturers, and they play an important role. At the same time, the performance of these components also determines the working performance of winding machine. The controller is the brain of winding machine, which is responsible for controlling power, arranging wires, etc. At present, there are two kinds of common controllers of winding machine. One is the general controller provided by the integrated supplier, and the other is the controller developed by the manufacturer. The common faults of the controller are the high-voltage control part and buttons. These problems cannot be solved by the general users themselves, and the manufacturer needs to be informed to repair them. The fault of frequency converter is also common, and the fault can be judged by looking at the display interface of frequency converter; Users with motor faults should pay attention to whether the motor has abnormal sound and normal temperature rise during use to judge whether the equipment is overloaded during use; Brake is a wearing part, which should be adjusted in time after the winding machine is used for a period of time, and replaced if necessary.

Among the reasons why the main motor can't start normally due to differential protection of the protection device, most cases are caused by the differential protection circuit except the fault of the motor itself. In the actual production process, due to the large vibration of the vertical mill and other reasons, it is easy to trip the differential protection caused by the loosening of the terminal of the current transformer at the motor side. Therefore, the fastening of the terminal of the current transformer at the motor side should be regarded as an important maintenance content in the usual equipment maintenance. ----
