一、前言 当前,能源问题日益被人们所重视,煤、石油、核能……终将用尽,而新的能源还未开发出来,那么如何节能,便是摆在我们面前的重要问题。 液压传动装置作为一个用能设备,在工作中要进行三次能量转换(电能→机械能→液压能→机械能), I. Introduction At present, the issue of energy is increasingly valued by people. Coal, petroleum and nuclear energy will eventually be exhausted and new energy sources have not been developed yet. So how to save energy is an important issue before us. Hydraulic transmission as an energy device, in the work to be carried out three times the energy conversion (electrical → mechanical energy → hydraulic energy → mechanical energy)
