To achieve continuous control of synchronous lifting and lowering of the 1200T high tonnage hydraulic cylinder, our company has matched it with a PLC single-point variable frequency speed control hydraulic system. Based on advanced computer control technology and a user-friendly interactive interface, parameters can be flexibly adjusted on-site, making the usage process more convenient.
Detailed Explanation of PLC Single Point Variable Frequency Speed Control Scheme:
This system is composed of one high pressure pump station, control valve group, hydraulic cylinder, pressure detection device and one set of variable frequency speed regulation device, etc. The system adopts a variable frequency speed regulator to control the oil pump motor. By adjusting the frequency of power supply, the motor speed is changed to achieve the purpose of continuously adjustable flow of the oil pump. With appropriate electrical control and detection devices, the loading control of the cylinder can be realized. The system adopts imported on-off valve groups to control the pressure relief of the oil cylinder. Relying on pulse width modulation control, the opening and closing frequency of the on-off valve groups is changed to achieve the purpose of slowly adjusting the flow rate of the oil pump. With appropriate electrical control and detection devices, the pressure relief control of the cylinder can be realized.
Parameters of PLC single point variable frequency speed control hydraulic system:
Control mode: Variable frequency speed regulation control
In recent years, KIET has been committed to the research and development of solutions and market expansion in the three major fields of lifting, hoisting and pushing. It has been widely applied in numerous fields such as multi-point synchronous pushing, skidding, lifting and tensioning of large components, weighing, tensioning, spatial attitude adjustment and intelligent walking of asymmetrical large components. Provide customers with safe and efficient equipment and services.
