【摘要】 论述提水灌溉的泵站监测特别是流量监测的必要性、重要性,列举秦淮新河泵站监测相关规程、规范和条例的规定,分析适用泵站监测的流量测量方法。介绍适用泵站测流的绕流管差压式流速流量计,该流量计具有突出优点,流速流量系数可准确标定,并不随雷诺数大小及使用年限而变化,取压管可方便地"插入"被测管道(或水泵吸水室),安装、维修方便,是包括南水北调等无直管段条件的低扬程大泵站及其它各类泵站简单、可信、准确度高的理想现场测流设备。更多还原

【Abstract】 The necessity and importance of pumping station monitoring,especially flow monitoring for irrigation were discussed. The regulations,codes and regulations of the new Qinhuai River Pumping Station were listed,and the flow measurement methods for pumping station monitoring were analyzed. The circumferential flow pipe differential pressure flow velocity of the applicable pump station were introduced,which had outstanding advantages. The flow velocity coefficient could be accurately calibrated,which was not changing with the Reynolds number size and the service life. The suction pipe could be conveniently inserted into the pipe( or water pump suction chamber),convenient for installation and maintenance,which was an ideal field measurement equipment with low lift pump station and other kinds of pump stations with the characteristics of simple,reliable and high accuracy.更多还原
