我县排灌站过去绝大部分配柴油机,近来通了电,多数换上了电动机。由于两种动力机转速不同,用户缺乏机泵转速要合理配套的知识,导致不少水泵超速运转,结果出水少,能耗高,浪费惊人,有的泵站装置效率只有10～2096。 1.蒲西乡涛头村有一泵站,安装的是浙农12×12(英寸)透平式离心泵,总扬程为4.5米,流量126升/秒,额定转速500转/分,配套功率8.8千瓦。可配套的却是17千瓦电动机,还带不动,起动后只能
In the past, most drainage and pumping stations in our county were equipped with diesel engines. Recently, electricity has been passed and most of them have been replaced with electric motors. Due to the different speed of the two power machines, the user lack of knowledge of the reasonable speed of the pump speed, resulting in a lot of speeding operation of the pump, resulting in less water, high energy consumption, an astonishing waste, and some pumping station device efficiency is only 10 ~ 2096. 1. Pu Xixiang Tao Toucun a pumping station installed in Zhejiang agriculture 12 × 12 (inch) turbine centrifugal pump, with a total head of 4.5 meters, the flow rate of 126 l / s, rated speed of 500 rev / min, supporting power 8.8 kilowatts. But it is supporting the 17-kilowatt motor, but also with fixed, only after starting
