1.油温过高的原因工程机械液压系统油温过高的原因主要是液压系统产生热量过大,且散热不充分。具体表现在液压系统存在设计缺陷,以及使用和保养等方面存在问题。(1)设计有缺陷液压系统存在的设计缺陷可能有以下几个方面:一是功率过剩。液压系统在工作过程中若有大量的能量损失,将使油温过高。对于柱塞泵-柱塞马达系统或柱塞泵
1. The reasons for the oil temperature is too high Hydraulic system engineering machinery oil temperature is mainly due to heat generated by the hydraulic system is too large, and the heat is not sufficient. Specific performance in the existence of hydraulic system design flaws, as well as the use and maintenance problems. (1) the design of defective hydraulic system design flaws may have the following aspects: First, excess power. Hydraulic system in the course of a large number of energy loss, will make the oil temperature is too high. For plunger pump - plunger motor system or plunger pump
