7.配管 (1)配管材料与方法中央式真空清扫设备的配管材料,一般建筑物为炭素钢管(镀锌)和螺纹形排水管接头组合使用,住宅则使用硬聚氯乙烯管(一般管)及排水用的同质管接头。在使用硬聚氯乙烯管时,由于空气流动,在管道上产生静电,所以,在住宅以外,应考虑安装铜地线。特别是混有合成树脂等的粉尘、碎屑的除尘时,应使用钢管。管接头的使用方法及扫除口的安装方法与排水管道相同。吸尘管道内可能吸入别针、针、橡胶圈等,所
7. Piping (1) Piping Materials and Methods The piping materials for the central vacuum cleaning equipment are generally used in combination with carbon steel pipe (galvanized) and screw-type drain pipe joints, while residential houses use rigid polyvinyl chloride pipe (general pipe) And drainage with the same pipe fittings. When using PVC pipes, static electricity is generated in the pipes due to air flow. Therefore, outside the house, consideration should be given to installing copper ground wire. In particular, mixed with synthetic resin dust, debris dedusting, the use of steel. The use of pipe joints and cleaning methods to install the mouth and drain the same. Vacuum pipe may be inhaled pins, needles, rubber rings, etc.
