液压机器使用的是液压油,需要根据设备要求选定粘度(32、46、68等)和规格(HL、HM、HV等),一般使用HM类(抗磨液压油)。液压油引就是利用液体压力能的液压系统使用的液压介质,在液压系统中起着能量传递、抗磨液压油、系统润滑、防腐、防锈、冷却等作用。
500吨液压机对液压油有什么要求?
1、 Quality requirements for hydraulic oil: The service life of excavators is directly related to the quality of hydraulic oil. It is necessary to choose hydraulic oil that meets the quality standards certified by the American Society of Engineers. This type of hydraulic oil has a 40& deg; ~100& deg; The viscosity index remains stable at C. When replacing, the same brand of hydraulic oil must be used.
二、对液压油粘度要求:液压油有N32HL,N46HL和N68HL等3种型号的抗磨液压油。其使用寿命为1,000h小时的液压机应使用N46HL+N68HL抗磨液压油(各占50%)。为15,000h小时以上的液压机应用N68HL抗磨液压油。
三、动力粘度是一个反应液压油流动性的指标。
Dynamic viscosity: It is the force required to produce a unit flow rate using a unit area of liquid layer per unit distance.
单位:pa.s(帕每秒)。
运动粘度:即动力粘度与密度的比值.
The customary unit is: Li Si. The lower the dynamic viscosity, the better the low-temperature fluidity. L-HM32, L-HM46, and L-HM68 are commonly used anti-wear hydraulic oils.
