As the application range of the pipe bender becomes wider and wider, we have to think about the next question, which is about the energy consumption of the pipe bender. As an important part of its production cost, only by reducing the energy consumption of the hydraulic pipe bender can it be possible to reduce the overall cost and enhance the competitiveness of the product in the market. After the test, it was found that the power consumption of the pipe bender is mainly the power consumption of the oil pump of the hydraulic system, and energy saving starts here.

From this point of view, the installation of a variable frequency speed control device is an effective way. It can rectify and filter AC power into DC power through the rectification link, and then convert it into AC power of different frequencies through the inverter link and output to the motor to achieve energy saving. purpose. In the process of reforming the hydraulic pipe bender machine, the form of dual-circuit with power frequency and frequency conversion is generally adopted; at the same time, the influence of environmental conditions, grid voltage, load size and other factors must be fully considered; the hydraulic energy-saving speed regulation should also be used as much as possible The power line of the device and the control line are routed separately, and the control line should be shielded as much as possible; don't forget to strengthen the anti-interference ability of the frequency conversion energy-saving speed control device.
