After customers purchase PE pipe fittings, the most important thing is the construction. Due to the changeable construction environment, special equipment for PE pipes such as electric fusion welding machine and hot fusion butt jointing machine may fail. Today, the editor summarizes some common problems. , Can help you solve the pipeline equipment problem as soon as possible, and ensure the safety of pipeline welding.
| Electric Fusion Welding Machine | Failure phenomenon | Possible Causes | elimination method |
| No power | Fuse burned out, power interface problem | Replace parts, reconnect | |
| After power on, the display does not show, the screen is blurred, and the machine beeps | The display screen is damaged (moisture, heat, impact, aging, disconnection of wiring) | Rewiring, replacing the display | |
| The current cannot rise | The external power supply is undervoltage, the power cord is laid too long | Check external power connection and re-lay | |
| Can not work normally according to the set parameters when the power is connected | The first stage current parameter setting is too low | Increase the first section of current parameters, the time is less than 30S, and then continue to perform normal parameter welding | |
| Display welding abnormality | PE pipe fitting heating element short circuit | Stop welding, wait until it cools down before welding | |
| Display output open circuit, resistance value exceeds the lower limit | Abnormal PE pipe fittings | Check the PE pipe fittings and replace the pipe fittings for welding | |
| Abnormal welding process, hot terminal | The copper cap of the output wire is aging | Correct the copper cap or replace with new accessories | |
| Display overcurrent, overvoltage | External power supply problem | Check the external power supply and rewire | |
| Butt Fusion Machine | The motor works but the hydraulic drive is invalid | The hydraulic oil is not enough at the nominal position | Check the hydraulic oil and select the specified hydraulic oil to supplement |
| Electric control box meter does not display | Damaged accessories or disconnected wires | Check accessories and lines for replacement or repair | |
| The heating plate does not heat or the temperature is not controlled | The line is off or the temperature controller is damaged | Check the wiring and replace the accessories | |
| Oil leakage at the high pressure pipe interface | Damaged quick plug | Replace the quick plug | |
| Component is not working | Poor contact of aviation plugs and sockets | Check and replace accessories | |
| The motor does not work | Wiring is off, motor is damaged | Check and repair |
The above is the fault reason and repair method of PE pipe electric fusion and hot fusion butt joint machine summarized by the editor. I hope to help everyone and have more PE pipe problems.
