工程車(chē)輛在高溫天氣下行駛和使用會(huì )使隱患上升，很多不的因素都是源自于持續的高溫。小型混凝土攪拌車(chē)車(chē)輛系統過(guò)熱的原因之一便是液壓油導致的，下面來(lái)講解一番。

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.

油液粘度過(guò)高，引起液流壓力丟失過(guò)大，轉化為熱能，會(huì )引起溫升過(guò)高；油液粘度過(guò)低，也會(huì )引起作業(yè)液壓泵及液壓元件內走漏大，發(fā)生熱量；

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，一些殘次油液，粘溫功能差，易乳化和生產(chǎn)氣蝕，折出氣泡等，會(huì )在液壓油高壓發(fā)生部分高溫并加劇元件的磨損，因而根據體系的負載及正常作業(yè)溫度要求，挑選適宜粘度的液壓油。

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.

合理挑選液壓油，特別是油液粘度，在條件答應的情況下，盡量選用低一點(diǎn)的粘度以削減粘度沖突丟失。

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.

長(cháng)期使用液壓油形成液壓油中存在雜質(zhì)，液壓油污染使馬達、多路換向閥、液壓油缸等液壓元件內部零件或密封件加快磨損，然后形成液壓油溫升高。辦法定時(shí)更換液壓油。

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.

定時(shí)查看液壓油箱中的液壓油高度，長(cháng)期作業(yè)有部分，始終保持液壓油油面高度在正常油位范圍內，然后確保油箱的散熱作用。

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.

攪拌車(chē)液壓油選用不妥或油質(zhì)差引起油溫過(guò)高這一內容的了解就到這里了，您對此有什么想咨詢(xún)的就來(lái)我們網(wǎng)站http://www.v811.cn進(jìn)行了解吧！
