  三、本公司可以提供该设备的拆卸、装车、安装、调试、培训等技术服务。

  四、 四柱压力机表面是否漏油的检查方法:

    1.物理隔离方法增加了四柱油压机受扰回路或装置与干扰源之间的距离。由于干扰强度与距离的平方成反比,建议大家采用稳定的电源。为了抑制四柱油压机电源噪声和电源与接地电缆之间的干扰,可以在电源与数控装置之间连接隔离

    2.屏蔽方法。为了防止四柱油压机和部件受到外部电磁场的影响,通常采用隔离屏蔽措施,通过反射或吸收进行电磁屏蔽或放电。

    3.接地方式:四柱油压机将其外壳与大地相连。对于保护接地,如果四柱油压机的系统接地作为系统接地与大地相连,也可以通过保护接地或系统接地等形式实现抗干扰。

    4.滤波器可以暂停输入干扰和信号传输线路上诱发的干扰。常用的是低通滤波器和DC滤波器,它们一般安装在四柱油压机的电源和数控装置之间。

First, the company sells cheap second-hand press, second-hand electric screw press, second-hand friction press, second-hand hydraulic press and other second-hand press, equipment more than 80% new, contact number: 86-13676907460

Second, the company sells used rotary kiln, used two-stage gas generator, used electric coke trap, used electric tar trap, used desulfurization denitrification equipment and other used equipment, equipment is more than 80% new, electrical accessories are complete.

3. The company can provide technical services such as disassembly, loading, installation, debugging and training of the equipment.

Iv. Inspection method for oil leakage on the surface of four-column press:

1. Physical isolation method increases the distance between the affected circuit or device of the four-column hydraulic press and the interference source.Since the intensity of interference is inversely proportional to the square of the distance, it is recommended to use a stable power source.In order to suppress the noise of the power supply of the four-column hydraulic press and the interference between the power supply and the ground cable, the power supply and the CNC device can be connected and isolated

2. Shielding method.In order to prevent the four - column hydraulic press and components from being affected by external electromagnetic field, isolation shielding measures are usually adopted, electromagnetic shielding or discharge by reflection or absorption.

3. Grounding mode: The four-column oil press connects its enclosure with the earth.For protection grounding, if the system grounding of a four-column hydraulic press is connected to the earth as a system grounding, anti-interference can also be achieved by means of protection grounding or system grounding.

4. The filter can suspend input interference and interference induced by signal transmission line.The low-pass filter and DC filter are commonly used. They are generally installed between the power supply of the four-column hydraulic press and the NUMERICAL control device.
