自来水管道流量一览表 市政给水管管径 市政给水管管径，一般用PE，口径从20mm -620mm 。一般是按水泵出口口径选配水管的管径；水泵连接的出水管不是管径越大越好，选的管径能满足流量的要求而且阻力损失又合理时为好。 HYPERLINK '/s?wd=%E9%95%80%E9%94%8C%E7%AE%A1&tncpr&fenlei=mv6quAkxTZn0IZRqIHckPjm4nH00T1dBuhFBrHbzuj-hmHcvnyDs0ZwV5Hcvrjm3rH6sPfKWUMw85HfYnjn4nH6sgvPsT6KdThsqpZwYTjCEQLGCpyw9Uz4Bmy-bIi4WUvYETgN-TLwGUv3EnW6sP1c3nHcz' \t '/question/_blank' 镀锌管是按 HYPERLINK '/s?wd=%E5%86%85%E5%BE%84&tncpr&fenlei=mv6quAkxTZn0IZRqIHckPjm4nH00T1dBuhFBrHbzuj-hmHcvnyDs0ZwV5Hcvrjm3rH6sPfKWUMw85HfYnjn4nH6sgvPsT6KdThsqpZwYTjCEQLGCpyw9Uz4Bmy-bIi4WUvYETgN-TLwGUv3EnW6sP1c3nHcz' \t '/question/_blank' 内径计算的, HYPERLINK '/s?wd=%E5%86%85%E5%BE%84&tncpr&fenlei=mv6quAkxTZn0IZRqIHckPjm4nH00T1dBuhFBrHbzuj-hmHcvnyDs0ZwV5Hcvrjm3rH6sPfKWUMw85HfYnjn4nH6sgvP |
