在生产中,人们往往对于一些水泵(或白水泵)失去工作特性标牌无法了解基本技术参数而头疼。为此可以用下面的几个经验公式估算它的流量、扬程及轴功率。 1.根据水泵口径估算流量: 流量=[水泵口径(英寸)]~2×5(m~3/h) 如4英寸泵的流量大致为多少? 答:其流量=4~2×5=80(m~3/h) 注:对于多级泵,按此公式计算的流量 In production, people often have a headache when some pumps (or white water pumps) lose their working characteristics and their signage can not understand the basic technical parameters. To this end can use the following empirical formula to estimate its flow, head and shaft power. 1. According to the pump caliber to estimate the flow: flow = [pump diameter (inch)] ~ 2 × 5 (m ~ 3 / h), such as 4 inch pump flow is roughly how much? A: The flow = 4 ~ 2 × 5 = 80 (m ~ 3 / h) Note: For multi-stage pump, according to the formula to calculate the flow
