摘要
给出了PP-R热水管沿程阻力损失的理论计算公式,并对其进行了实验研究。结果表明,计算值与实验值基本吻合,实际工程中可应用本文的计算公式。针对PP-R管件的连接特点,对局部阻力损失进行了测试,通过分析给出了一个合理的取值范围。
Presents the theoretical calculation formula and performs experiments of frictional resistance loss for PP-R hot water pipes. As a result, the values from calculation are basically consistent with those measured from the experiments, and the formula can be applied to actual project. Based on the connecting characteristics of the PP-R pipes, tests the local pressure loss and presents a reasonable value range through an analysis.
