液压油温度是工程机械液压系统稳定性的重要指标,本文针对我公司履带式起重机液压油温度过高问题,从液压系统的基本原理出发,分析了油温过高原因,查找出故障部位,并提出改进措施。1.故障现象我们在对1台新型履带起重机进行热平衡试验时,发现该机液压油温度上升过快。试验时环境温度为28℃,该机带载直线行走过程中,监测器测得其液压
Hydraulic oil temperature is an important indicator of hydraulic system stability of construction machinery. In this paper, according to the problem of high temperature of hydraulic oil of crawler cranes in our company, starting from the basic principle of hydraulic system, the reason of oil temperature is analyzed, Put forward improvement measures. 1. Symptom When we carried out a heat balance test on a new crawler crane, we found that the temperature of the hydraulic oil of the machine rose too fast. Test environment temperature is 28 ℃, the aircraft carrying a straight line during walking, the monitor measured the hydraulic
