Energy-saving Control System of Bubble Film Machine

发布日期:[2019-05-14]     点击率:

At present, most of the bubble film machines belong to the hydraulic transmission bubble film machine, and the power in the hydraulic transmission system is provided by the motor-driven oil pump. In the process of extrusion cycle, the flow and pressure of bubble film machine are different in different processes. Flow and pressure of different processes must be regulated by flow valve and pressure valve. Because the output power of quantitative pump can not be adjusted, excess energy can only be consumed in baffle, oil leakage and oil temperature rise, which aggravates the wear of various valves and causes oil. Excessive temperature, excessive motor noise, and shortened mechanical life and other phenomena. In addition, the capacity of the designed motor is much higher than the actual needs, and there is a phenomenon of "big horse car", resulting in a large amount of waste of electricity.

In the extrusion process, each action is completed with the elaborate coordination of several parameters, such as time, pressure, speed and position. That is to say, the displacement at a certain position has the corresponding pressure and speed, and the pressure and speed are variable in different positions and time. At the same time, after each action is completed, the termination signal is sent to the program controller, and the program controller receives the signal before issuing the instruction to execute the next action.

Energy Saving Principle of Bubble Film Machine

The traditional bubble film machine uses a quantitative pump to supply oil. The requirements of speed and pressure for each action in the manufacturing process are different. It uses the proportional valve of the bubble film machine to adjust the excess oil bypass to the tank by overflow. In the whole process, the speed of the motor is unchanged, so the fuel supply is fixed, and the execution action is gaps, and also parallels. It can't be full load, so there is a lot of waste space for quantitative oil supply.
