热熔机接 PPR 管教程:设备操作全流程演示​

2025-09-23

在家庭装修或管道安装工程中,PPR管的连接是一项关键任务。热熔机作为连接PPR管的常用设备,其操作流程需要严格遵循规范,以确保连接质量。下面为大家详细介绍热熔机接PPR管的设备操作全流程。

首先,准备工作至关重要。检查热熔机是否通电正常,温度显示是否准确。一般来说,PPR管的热熔温度在260℃左右。同时,准备好切割工具,将PPR管切割成所需长度,切口要平整,无毛刺。

接着,进行管材和管件的清洁。用干净的布擦拭管材和管件的连接部位,去除灰尘和油污,以保证热熔连接的密封性。

然后,开始热熔操作。将热熔机的模头安装好,等待温度达到设定值。当温度稳定后,将管材插入模头的一端,管件插入模头的另一端,插入深度要符合规定要求。一般插入时间为3-5秒,具体时间根据管材和管件的规格而定。

插入完成后,迅速将管材和管件从模头中取出,并立即进行连接。将管材垂直插入管件中,保持一定的压力,确保连接紧密。连接过程中,要注意保持管材和管件的同心度,避免倾斜。

连接完成后,进入冷却阶段。让连接好的PPR管静置一段时间,自然冷却。在冷却过程中,不要对管道施加外力,以免影响连接质量。冷却时间根据环境温度和管材规格而定,一般为10-15分钟。

最后,进行质量检查。检查连接部位是否有缝隙、变形等缺陷。可以通过水压试验来检测连接的密封性,确保管道系统的正常运行。

总之,掌握热熔机接PPR管的设备操作全流程,是保证PPR管连接质量的关键。通过以上步骤的详细演示,希望能帮助大家在实际操作中熟练运用,顺利完成PPR管的连接工作。
