为确保液压系统工作正常、可靠、减少故障和延长寿命,必须采取有效措施控制油的污染。1.控制油温油温过高往往会给液压系统带来以下不利影响:(1)油液黏度下降,使活动部位的油膜破坏、摩擦阻力增大,引起系统发热、执行元件(例如液压缸)爬行。油液黏度下降可导致泄漏增加,系统工作效率显著降低。 In order to ensure that the hydraulic system is working properly, reliably, reducing faults and prolonging the life, effective measures must be taken to control the oil pollution. 1. Control the oil temperature Oil temperature is often too high will bring the following adverse effects on the hydraulic system: (1) the viscosity of the oil decreased, the active site of the film damage, increased frictional resistance, causing the system fever, the implementation of components (such as hydraulic cylinder )crawl. Decreasing fluid viscosity can lead to increased leakage and significantly lower system efficiency.
