使用往复泵能否节约能源,目前还有争议。为了说明这一问题,首先来看往复泵在两次世界“能源危机”前后的发展情况。日本学者神田直在“最近往复泵”一文中,根据《机械工学年鉴》对1972～1981年的各类泵产量、产值及增长率进行了一次统计。统计结果表明:各类泵总产量在十年期间约增长了一倍半,而往复泵在经过两次世界“能源 The use of reciprocating pumps can save energy, there are still controversial. To illustrate this issue, let’s begin by looking at the development of reciprocating pumps around the two “energy crises” of the world. Japanese scholar Kanda straight in the “recent reciprocating pump,” a article, according to “Mechanical Engineering Yearbook” of various types of pumps from 1972 to 1981, the output value and growth rate of a statistics. The statistical results show that the total output of various types of pumps has increased by about one and a half times during the ten-year period, while the reciprocating pumps have experienced two times of "energy
