工程车辆在高温天气下行驶和使用会使隐患上升，很多不的因素都是源自于持续的高温。小型混凝土搅拌车车辆系统过热的原因之一便是液压油导致的，下面来讲解一番。
Driving and using engineering vehicles in hot weather will increase the potential safety hazards. Many unsafe factors are derived from the continuous high temperature. One of the reasons for the overheating of the vehicle system of the small concrete mixer is the hydraulic oil. Let's explain it.
油液粘度过高，引起液流压力丢失过大，转化为热能，会引起温升过高；油液粘度过低，也会引起作业液压泵及液压元件内走漏大，发生热量；
If the viscosity of oil is too high, the loss of fluid pressure will be too large, which will be converted into heat energy, and the temperature rise will be too high; Too low oil viscosity will also cause large leakage and heat in the operating hydraulic pump and hydraulic components;
此外，一些残次油液，粘温功能差，易乳化和生产气蚀，折出气泡等，会在液压油高压发生部分高温并加剧元件的磨损，因而根据体系的负载及正常作业温度要求，挑选适宜粘度的液压油。
In addition, some defective oil fluids have poor viscosity temperature function, are easy to emulsify and produce cavitation, break bubbles, etc., which will cause partial high temperature at the high pressure of hydraulic oil and aggravate the wear of components. Therefore, hydraulic oil with appropriate viscosity is selected according to the load of the system and the requirements of normal operating temperature.
合理挑选液压油，特别是油液粘度，在条件答应的情况下，尽量选用低一点的粘度以削减粘度冲突丢失。
Select the hydraulic oil reasonably, especially the oil viscosity. If conditions permit, try to select a lower viscosity to reduce the loss of viscosity conflict.
长期使用液压油形成液压油中存在杂质，液压油污染使马达、多路换向阀、液压油缸等液压元件内部零件或密封件加快磨损，然后形成液压油温升高。办法定时更换液压油。
There are impurities in the hydraulic oil caused by long-term use of hydraulic oil. The pollution of hydraulic oil accelerates the wear of internal parts or seals of hydraulic components such as motors, multiple directional valves, hydraulic cylinders, etc., and then causes the rise of hydraulic oil temperature. Solution Replace the hydraulic oil regularly.
定时查看液压油箱中的液压油高度，长期作业有部分，始终保持液压油油面高度在正常油位范围内，然后确保油箱的散热作用。
Regularly check the hydraulic oil level in the hydraulic oil tank. Long term operation is partial. Always keep the hydraulic oil level within the normal oil level range, and then ensure the heat dissipation effect of the oil tank.
