我国农用水泵量大面广,占水泵拥有量总动力的65％,每年耗电120—150亿度,耗油200多万吨。由于制造和使用上的原因,多数水泵使用效率较低,造成能源的很大浪费。为了提高农用水泵的使用效率,其节能方法:1.把好选型关,避免选泵过大。经常可以看到,在泵的效率问题上,斤斤计较于多或少1％,而由于保守的选泵思想,造成选泵过大,却浪费了5—10％甚至15％的动力。这是各种能源浪费中最大的 China’s large agricultural water pump, accounting for 65% of the total power pump, power consumption of 120-150 billion degrees per year, more than 200 million tons of fuel consumption. Due to the manufacturing and usage reasons, most pumps are less efficient to use, resulting in a great waste of energy. In order to improve the efficiency of agricultural water pumps, the energy-saving methods: 1. Selection of good type, to avoid pump too large. Often it can be seen that on pump efficiency problems, 1% is more or less preoccupied, and 5-10% or even 15% is wasted due to the conservative pump selection. This is the largest of all kinds of energy waste
