style="text-indent:25px">變頻泵流量：轉(zhuǎn)輪（葉輪）公稱直徑為1m，在1m水頭（揚(yáng)程）下的水力機(jī)械過流量，由流量相似關(guān)系導(dǎo)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(nèi)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(nèi)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(diǎn)速度的標(biāo)量積。變頻水泵正確啟動主要有三個步驟，包括了起動前準(zhǔn)備、起動、停車。</p><p
