Factors affecting normal operation of PE pipe welding machine
Due to improper operation and environmental changes during the use of PE pipe welding machine , the quality of the fused interface may be affected. Reasonably avoiding these factors can prolong the service life of PE pipe welding machine.
电压波动对接口质量的影响 。 1. The impact of voltage fluctuations on interface quality . 给定的电熔管件内电阻丝电阻值一定，因此，电阻丝的发热功率完全取决于电源提供的电压，故焊口的质量会因电压波动影响加热功率而变坏。 The resistance value of the resistance wire in a given fused pipe in a PE pipe welding machine is constant. Therefore, the heating power of the resistance wire completely depends on the voltage provided by the power supply, so the quality of the welding joint will be deteriorated due to the voltage fluctuation affecting the heating power.
，减少对 PE管焊接机正常工作的影响。 2. The effect of welding time on the interface The heat range required for each specification of the fused pipe is fixed. Too much or too little heat will have a fatal impact on the welding quality, and the welding voltage and the resistance of the pipe are fixed. Under the premise that welding time is the only determinant of the heat generation of the pipe, it is necessary to accurately control the welding temperature and ambient temperature to reduce the impact on the normal operation of the PE pipe welding machine.
中环境温度的变化，直接影响到熔接区的热传递条件，进而影响熔接的质量，因此 PE管焊接机 必须能监控环境温度，并能自动根据偏差结果对输出参数作相应调整。 3. The change of the ambient temperature during the use of the PE pipe welding machine directly affects the heat transfer conditions in the welding zone and then affects the quality of the welding. Therefore, the PE pipe welding machine must be able to monitor the ambient temperature and automatically output parameters based on the deviation Make adjustments accordingly.
。 4. The influence of bad operation on the quality of the splice interface . 所谓不良操作，一方面指焊接时管材的清洗或刮削不符合规范（特别是承插口装配不到位，插口端部有较大斜度等），这就要求操作者必须具备一定的焊接知识。 The so-called poor operation of the PE pipe welding machine refers to the fact that the cleaning or scraping of the pipe material during welding does not meet the specifications (especially the socket is not assembled properly, and the end of the socket has a large slope, etc.), which requires the operator to have a certain Welding knowledge. PE管焊接机 本身的设置来避免 。 On the other hand, errors occurred when welding parameters are input. This aspect should be avoided by the setting of the PE pipe welding machine itself .
