How to connect medium frequency pipe bender

Medium frequency pipe bending machine is a kind of equipment used for processing metal pipes, it uses the principle of medium frequency induction heating, by heating the pipe to soften it, and then bending it into the desired shape by bending the mold. In connection, the main components of the medium frequency pipe bender include power supply, capacitor, induction coil and control system. The following will introduce the connection method of the medium frequency pipe bender in detail.

1. First, determine the power demand of the medium frequency pipe bender. Select the corresponding power supply according to the rated voltage and frequency of the device to ensure that the voltage and frequency of the power supply match the device. Under normal circumstances, the medium frequency pipe bender usually uses a three-phase AC power supply with a rated voltage of 380V and a frequency of 50Hz.

2. Connect the power input terminal. Connect the three phase lines of the power supply (L1, L2, L3) to the electrical phase lines of the medium frequency pipe bender correctly to avoid reverse phase line connection.

3. Connect capacitors. The capacitor of the medium frequency pipe bender is used to store electrical energy, which is provided to the induction coil for heating. Before connecting the capacitor, it is first necessary to check whether the rated voltage and capacity of the capacitor are consistent with the equipment requirements. Then, the positive and negative terminals of the capacitor are respectively connected to the capacitor input terminal of the medium frequency pipe bender.

4. Connect the induction coil. The induction coil is a key component in the medium frequency pipe bender, which is used to generate a high frequency electromagnetic field to heat the pipe. Induction coils are usually composed of multiple coils, which need to be connected according to the specific equipment structure and requirements. Under normal circumstances, the connection method of induction coil includes series and parallel two kinds.

- Series connection: Connect one terminal of the induction coil to the negative terminal of the capacitor, and then connect the other terminal of the induction coil to the positive terminal of the capacitor. This connection method is suitable for medium frequency pipe bender with low power.

- Parallel connection: The two terminals of the induction coil are respectively connected to the two terminals of the capacitor. This connection method is suitable for medium frequency pipe bending machines with high power.

5. Connect the control system. The control system of the medium frequency pipe bender is used to control the operation and parameter setting of the equipment, which is usually composed of PLC (programmable logic controller) or numerical control system. According to the requirements of specific equipment, the control system is connected with the relevant parts of the medium frequency pipe bender to ensure its normal operation.

6. Connect the device. According to the actual needs, the medium frequency pipe bender may need to connect some equipment, such as water cooling system, air source system, etc. According to the interface requirements of the device, the device is connected to the medium frequency pipe bender.

After the wiring is completed, it is necessary to conduct a comprehensive inspection and test to ensure that the connection of each component is solid and reliable, and carry out related safety checks, such as grounding protection. In addition, the correct operation and maintenance should be carried out according to the operation manual and operation manual of the equipment to ensure the stable operation and efficient work of the medium frequency pipe bender.

Summary: The wiring method of the medium frequency pipe bender includes the steps of connecting the power supply, connecting the capacitor, connecting the induction coil, connecting the control system and connecting the equipment. During the wiring process, carefully check the device requirements and wiring diagram to ensure that each component is correctly connected. In addition, comprehensive inspections and tests are needed to ensure the stable operation and efficient work of the equipment.
