正确地选择液压软管的直径,除需考虑强度外,最重要就是液压系统所能允许的压降值了。因为压力降能产生热能,因而造成能量损失,效率降低,因此必须避免在系统中产生过量的液体热能。有几个因素,包括该软管使用的频率,会影响设计者所考虑的软管管径值。例如:在连接拖拉机与牵引机具,如象犁之类的管路中,只有当被牵引的机具上升或下降时。管路才会受到加压,而且动作也不是经常 Correct choice of hydraulic hose diameter, in addition to the need to consider the strength, the most important is the hydraulic system can allow the pressure drop value. Because the pressure drop can generate heat energy, resulting in energy loss, the efficiency is reduced, so excessive liquid heat must be avoided in the system. Several factors, including how often the hose is used, affect the hose diameter that the designer is considering. For example, in a pipe that connects a tractor to a towing implement, such as a plow, only when the towed implement is raised or lowered. The pipeline will be pressurized, and the action is not often
