The key technologies of bundle puller cover many aspects such as mechanical design, hydraulic control, automation technology and safety protection. Understanding these key technologies is critical to selecting the right equipment, optimizing operating procedures, and ensuring safety.
1. Clamping technology:
Clamping force calculation and control: Accurate calculation of the required clamping force is key. If the clamping force is too small, the tube bundle may slip, and if the clamping force is too large, the tube bundle may be damaged. The advanced extraction machine is equipped with force sensors and a closed-loop control system that can monitor and adjust the clamping force in real time to ensure safe and reliable operation.
Clamp design and material: The shape, size and material of the clamp jaw need to be selected according to the specifications and material of the tube bundle. Common clamping jaw materials include high-strength alloy steel, stainless steel, etc. Some special application scenarios may require the use of high temperature resistant, corrosion resistant or anti-slip materials.
Multi-point synchronous clamping: For large or heavy tube bundles, the use of multi-point synchronous clamping technology can ensure that the tube bundle is stressed evenly and prevent deformation or damage.
2. Walking and Guidance Technology:
The accuracy and stability of the traveling mechanism: The accuracy and stability of the traveling mechanism directly affect the smoothness and efficiency of the tube bundle extraction. The high-precision traveling mechanism ensures that the tube bundle moves along the correct trajectory to avoid collisions and jamming.
Reliability of the guide system: The function of the guide system is to guide the movement trajectory of the tube bundle and prevent collision or friction between the tube bundle and the shell. Reliable guidance systems are essential to protect tube bundles and housings.
Automatic alignment technology: Some advanced extraction machines are equipped with automatic alignment systems that can automatically identify and align the position of the tube bundle, simplifying the operating process and improving efficiency.
3. Hydraulic control technology:
Stability and response speed of the hydraulic system: The stability and response speed of the hydraulic system directly affect the speed and accuracy of the tube bundle extraction. The high-performance hydraulic system can provide smooth power output and respond quickly to operating instructions.
Proportional valve control: The proportional valve can accurately control the movement speed and pressure of the hydraulic cylinder to achieve more precise operation.
Pressure and flow control: Real-time monitoring and control of the pressure and flow of the hydraulic system can ensure safe operation and optimal performance of the system.
4. Automation and control technology:
PLC control system: PLC control system can automate operations, improve efficiency and reduce the risk of human error.
Human-machine interface (HMI): A friendly HMI allows operators to monitor equipment status, set parameters and perform operations.
Remote control: Some advanced extraction machines support remote control functions, allowing remote operation and monitoring.
5. Safety protection technology:
Emergency stop device: In an emergency, the operation of the equipment can be quickly stopped to prevent accidents.
Overload protection: When the clamping force or traveling force exceeds the set value, the overload protection device will automatically activate to protect the equipment and pipe bundles.
Safety interlock: The safety interlock device can ensure the correctness of the operation sequence and prevent accidents caused by misoperation.
Warning System: An audible and visual alarm system can alert operators to potential dangers.
Future development trends:
Intelligent: Combining artificial intelligence and machine learning technology to achieve more intelligent operation and maintenance.
Digitalization: Integrate sensors and data analysis technology to achieve real-time monitoring and predictive maintenance of equipment status.
Integration: Integrate the bundle puller with other heat exchanger maintenance equipment to form an integrated solution.
An in-depth understanding of these key technologies will help to better select, use and maintain bundle pullers, maximize their effectiveness, and ensure safe and efficient heat exchanger maintenance operations.
