15 years of professional reform experience create brilliant in market

In the production line of iron and steel plant, the hydraulic system is the main source of its operation power. The improvement of hydraulic system efficiency can play a key role in energy saving and emission reduction of enterprises

1. Servo energy saving retrofitting project of Iron and steel machinery

1) According to the nature of the hydraulic station and the number of main pumps, working principle and characteristics, combined with the process requirements of each region, as well as the load of the equipment, the servo upgrading improvement scheme of the system is determined.

根据实际反馈需求按需输出,避免系统做无用功,达到节能效果.

2) According to the actual feedback demand, output on demand to avoid the system to do idle work, to achieve energy-saving effect.

采用高分辨率的位置传感器及压力传感器进行反馈控制,可以进行轧辊的位置闭环控制以实现髙精度的棍缝调整.

Using high-resolution position sensor and pressure sensor for feedback control, the closed-loop control of roll position can be realized to achieve high-precision gap adjustment.

对原有的连轧管机进行改造,加强生产工艺过程的调控管理,以改善产品质量以及优化整个机组设备的使用.

3) In order to improve the quality of products and optimize the use of the whole plant, the original pipe rolling mill was reformed and the control and management of the production process was strengthened.

Servo control system supply pressure and flux according to the machine’s demand
4) PLC outputs the corresponding signals according to each action to control the output frequency of the driver, so that the output flow of pump is precisely matched with the requird
5) the external HMI is used to set up all the running parameters, showing the system running status and abnormal alarm information
6) Don't change the original control system and hydraulic system

Equipment projects that can be retrofitted for servo energy saving
1) Hydraulic station
2) Punching machine
3) Tube expander
4) Shearing machine
5) Ring furnace
6) Electrohydraulic hammer

2. Advantage

1) Super energy saving: energy saving rate 45%-80%
2) Super stability: Widely speed rang and strong overload capacity
3) Excellent voltage range: 330V-600V
4) Both have motor KTY and PTC overheating protection function
5) Many additional green values: Extend the using life, Low noise, Reduce the use of cooling water
6) We supply the whole completed servo system:Including servo driver, servo motor, SUMITOMO gear pump, electric cabinet, electric resistance, pressure sensor, magnet ring, press-flow shields semaphore wire, power cable, oil flange, oil suction pipe, semaphore converts board, U-steel and so on
