style="text-indent:25px">變頻泵對流量進行調節(jié)的方式：通過對泵轉速的改變來對流量進行調節(jié)。這種方法需要在泵的平均流量與轉速成正比的情況下進行，而往復泵正好有這個特性，所以，可以通過這種方式來看對流量進行調節(jié)；此外，通過改變轉速調節(jié)流量的方法還需要對裝置或電動機進行調速，但是，在小流量的時候，沖程數(shù)太小而導致排液時間過長，這對于某些化學反應是不允許的，所以還需要多多的注意。通過對泵活塞(柱塞)的行程長度的調節(jié)來對流量進行調節(jié)，這種方法的一大優(yōu)點是計量精度高，而且即使是在小流量的情況下，仍然可以滿足線性要求，可以說是比較有效的一種方法。</p><p style="text-indent:25px">變頻泵流量：轉輪（葉輪）公稱直徑為1m，在1m水頭（揚程）下的水力機械過流量，由流量相似關系導出，用Q11表示，單位為m3/s。變頻泵功率：功率是指物體在單位時間內所做的功的多少，即功率是描述做功快慢的物理量。功的數(shù)量一定，時間越短，功率值就越大。求功率的公式為功率=功/時間。功率表征作功快慢程度的物理量。單位時間內所作的功稱為功率，用P表示。故功率等于作用力與物體受力點速度的標量積。變頻水泵正確啟動主要有三個步驟，包括了起動前準備、起動、停車。變頻水泵技術創(chuàng)新點：把交流變頻調速技術應用于城鄉(xiāng)供水及農(nóng)業(yè)灌溉中，達到節(jié)水節(jié)能效果。</p><div
