Operating instructions for PE pipe welding machine

PE管焊接 各部件的电源接通,必须使用 220V、50Hz的交流电,电压变化在±10%以内,电源应有接地线。 1. Connect the power supply of each part of the PE pipe welding machine , you must use 220V, 50Hz AC, the voltage change is within ± 10%, the power supply should have a ground wire. At the same time, ensure that the surface of the heating plate is clean and free of scratches.

When welding large-diameter pipes, it is best to flatten them with discarded pipe joints or brackets to protect the pipe and reduce friction during welding. The distance between the two ends of the welding must meet the requirements of the installation of the milling cutter, and the two ends of the welding to be fully contacted when the clamp is closed, and the hydraulic cylinder does not reach the maximum stroke.

4. Start the milling cutter, close the fixture, and cut both ends of the pipe (pipe fitting).

5. When continuous cutting is formed, open the clamp and close the milling cutter. This process must be performed in the order of reducing the pressure, then opening the fixture, and finally closing the milling cutter.

6. Remove the milling cutter, close the fixture, and check the gap between the two ends of the pipe (the gap must not be greater than 0.3mm). When removing the milling cutter from the frame, avoid collision between the milling cutter and the end surface. If it has occurred, remilling and milling Do not touch the good end surface or contaminate it with oil.

7. Check the coaxiality of the pipe (the maximum amount of distorted edges is 10% of the thickness of the tube wall). When the gap and the amount of dislocated edges at the two end surfaces cannot meet the requirements, the weldment should be re-clamped and milled. Proceed to the next step.

8. Check whether the temperature of the heating plate is appropriate (210 degrees ± 10 degrees). The red indicator light on the heating plate should be on or flashing. When the red light on the heating plate lights up for the first time, it is best to wait another 10 minutes to use it so that the temperature of the entire heating plate is uniform.

10. When the protrusions between the pipes (pipe fittings) are uniform and the height reaches the requirements, press the endothermic timekeeping button at the same time to start recording the endothermic time.

11. After the heat absorption time is reached, quickly open the clamp and remove the hot plate. When taking the heating plate, avoid collision with the molten end. If it has occurred, the entire welding process should be restarted after the molten end surface is completely cooled.

12. Close the fixture quickly, and adjust the pressure at a constant speed within the specified time, and simultaneously press the register to record the cooling time. After the clamp is closed, the pressure should be uniformly increased, not too fast or too slow, and it should be completed within the specified time to avoid the formation of false or virtual welding. This pressure should be maintained until the weld is completely cooled.

13. After the cooling time is reached, reduce the pressure to zero, open the clamp, and remove the welded pipe (pipe fitting). PE管焊接机 ,应拆下液压导线,并及时做好接头处的防尘工作。 Before unloading the pipe, the system pressure must be reduced to zero. If the PE pipe welding machine needs to be moved , the hydraulic wires should be removed and the joints must be protected from dust in time.

14. In order to ensure the quality of the interface, after the welding is completed, the quality of the interface should be checked.
