大家都知道流体传动遵循伯努利方程,包括:液动力、静压能、势能。其中的动力式传动和容积式传动是有区别。不管是液力传动还是液力输送,做液力变矩器还是做泵,都属于是无接触式的,在加工上与液压元件高精密配合多摩擦副有很大的差异,所以国内水泵、水阀厂家发展迅速,第一桶金来的很快。发展到现在这个阶段,大家又觉得咱们的水泵、水阀在质量上、在高附加值上差强人意,实际上就 We all know that fluid transmission follows the Bernoulli equation, including: hydrodynamic, hydrostatic, potential energy. One of the power transmission and volumetric transmission is different. Whether it is hydraulic transmission or hydraulic transmission, do torque converter or do the pump, are all non-contact, with the high precision hydraulic components in the processing of friction with a lot of differences, so the domestic pump, Valve manufacturers have developed rapidly, the first bucket of gold to come quickly. To this stage of development, we also feel that our pumps, valves in the quality, unsatisfactory high value-added, in fact,
