一、选择液压油的原则 1.选择工程机械用液压油的依据 (1)液压件。不同的液压元件对所用液压油都有一个最低的配置要求,因此选择液压油时,应注意液压件种类及其使用的材质、密封件和涂料或油漆等与液压油的相容性。保证各运动副润滑良好,使元件达到设计寿命,满足使用性能的要求。 液压泵是对液压油的黏度和黏温性能最敏感的元件之一,因此,常将系统中泵对液压油的要求作为选
First, the principle of choice of hydraulic oil 1. Select the basis for hydraulic machinery for construction machinery (1) hydraulic parts. Different hydraulic components have a minimum configuration requirements for the hydraulic fluid used. Therefore, when selecting the hydraulic fluid, you should pay attention to the type of hydraulic components and materials used, seals and paint or paint compatibility with hydraulic oil. Lubrication of the movement to ensure that good, so that components to achieve the design life, to meet the performance requirements. Hydraulic pump is the viscosity of oil and viscosity-temperature performance of the most sensitive components, therefore, often the system of hydraulic pump oil requirements as a selection
