凡是包含有压液体的系统,在系统中的不同元件连接在一起的分界处都有潜在的泄漏点,而且随着系统压力的升高,泄漏的危险也增加。因此,对于粘度较低而使用压力较高的液压油来说,泄漏可能给用户带来问题。这样损失系统油液是肮脏而昂贵的,但如果系统能正确地设计与维护,它不一定构成一个大问题。然而某些液压系统的确漏油这一事实在公众中给液压造成很坏的形象,并给倾向于其他传动形式的竞争者一个有用的口实。 In systems containing pressurized fluid, there are potential leaks at the boundaries where different components in the system are connected together and the risk of leakage increases as system pressure increases. Therefore, for lower viscosity and the use of higher pressure hydraulic oil, the leak may give users problems. This loss of system oil is dirty and expensive, but it does not necessarily pose a big issue if the system is properly designed and maintained. However, the fact that some hydraulic systems actually leak oil creates a bad image of the hydraulic pressure in the public and provides a useful excuse for competitors who prefer other forms of transmission.
