With more and more applications of the pipe bending machine, we have to think about the next question, which is about the energy consumption of the pipe bending machine. As an important part of its production cost, it is possible to reduce the overall cost and enhance the competitiveness of the product in the market only by reducing the energy consumption of the pipe bending machine. After the test, it is found that the energy consumption of the pipe bending machine is mainly the energy consumption of the hydraulic system oil pump, and the energy saving should start from here.

From this point of view, the installation of frequency conversion speed regulation device is an effective way, it can through the rectification link will be ac electric energy through rectification, filtering for dc electric energy, and through the inverter link into different frequency AC electric energy output to the motor, in order to achieve the purpose of energy saving. In the process of reforming the hydraulic pipe bending machine, the form of double circuit with power frequency and frequency conversion is generally adopted. At the same time, the use of environmental conditions, grid voltage, load and other factors should be fully considered; Also try to separate the power line and control line of the hydraulic energy saving speed regulating device, control line as far as possible to use shielded line; Don't forget to strengthen the anti-interference ability of frequency conversion energy-saving speed regulating device.
