① Oil temperature is one of the main factors that affect oil pressure
當自動上料車發動機油溫過高時，不光使耗油量增加(滲漏、蒸騰、燃燒)，而且影響機油質量，使自動上料車發動機各機件衝突外表的油膜不易構成和保持，形成主油道油壓不能建立，然後加重機件磨損。而水溫對油壓的影響必須經過油溫才幹完成。所以具有必定的間接性，需要必定的時間。
When the engine oil temperature is too high, it will not only increase the fuel consumption (leakage, transpiration, combustion), but also affect the quality of the engine oil, which will make it difficult to form and maintain the oil film on the surface of the conflict parts of the automatic loading car engine, and the oil pressure in the main oil channel can not be established, and then the parts will be worn. The effect of water temperature on oil pressure must be completed by oil temperature. Therefore, it has certain indirectness and needs certain time.
②自動上料車油溫過高直接損害發動機
② The high oil temperature of the automatic loader directly damages the engine
自動上料車發動機的溫度過高是指發動機的油溫、水溫超過90℃。因為熱脹冷縮的原理，在溫度提升後容易照成發動機空隙縮小，構成嚴重磨損或“拉缸”。
The high temperature of the engine of the automatic loading car means that the oil temperature and water temperature of the engine exceed 90 ℃. Because of the principle of thermal expansion and cold contraction, it is easy to reduce the gap of the engine after the temperature is increased, resulting in serious wear or "cylinder pulling".
當過度磨損產熱量超過散熱量時，軸瓦溫度就會上升，部分溫度到達鉛的熔點，軸瓦中的鉛和銅就會熔化，最終導致曲軸與軸承嚴重燒蝕或發生“瓦抱軸”，後果不堪設想。因此，當自動上料車油和水的溫度一起過高時，應當先降油溫。
When the heat produced by excessive wear exceeds the heat dissipation capacity, the temperature of Bearing Bush will rise, and part of the temperature will reach the melting point of lead, and lead and copper in the bearing bush will melt, which will eventually lead to serious ablation of crankshaft and bearing or "Bush shaft holding", and the consequences are unimaginable. Therefore, when the temperature of oil and water is too high, the oil temperature should be reduced first.
③ 先降水溫對自動上料車發動機主軸油道油壓建立影響大
③ First cooling water temperature has a great influence on the establishment of oil pressure in the main shaft oil channel of the engine of automatic loading vehicle
眾所周知，降水溫一般是采取“降負荷，高轉速”的辦法。當轉速過高時，就會增大活塞連軒組的慣性力和離心力，使曲軸軸承的負荷加大。一起，軸頸與軸瓦的相對衝突速度也會增大，使單位時間內發生的熱量增加，機油泵油量下降，許多的機油從主油道內被甩出，然後導致各機件衝突外表因無滿足的潤滑油而加重磨損，油溫進一步上升。
As we all know, precipitation temperature is generally adopted "load reduction, high speed" approach. When the speed is too high, the inertia force and centrifugal force of the piston Lianxuan group will be increased, and the load of the crankshaft bearing will be increased. At the same time, the relative collision speed between the journal and the bearing bush will also increase, resulting in the increase of heat per unit time, the oil volume of the oil pump will decrease, and a lot of oil will be thrown out from the main oil duct, which will lead to the collision of various parts, and the wear of the surface will be aggravated due to the lack of satisfied lubricating oil, and the oil temperature will further rise.
④ 自動上料車降油溫可減緩水溫升高的速度
④ Lowering the oil temperature of the automatic loading car can slow down the speed of water temperature rising
自動上料車水箱存在的作用，就是下降發動機的油溫。降油溫一般采用“降負荷，低轉速”的辦法。這時，冷卻液雖然在高溫零件處熱交換的時間長，但水流速度減緩了，延長了散熱時間。一起，又因為負荷削減、轉速下降，各運動機件衝突發生的熱量也相應削減。
The function of the water tank of the automatic loading car is to reduce the oil temperature of the engine. The method of "reducing load and low speed" is generally used to reduce oil temperature. At this time, although the heat exchange time of coolant at the high temperature parts is long, the water flow speed slows down and the heat dissipation time is prolonged. At the same time, due to the load reduction and speed drop, the heat generated by the conflict of the moving parts is also reduced accordingly.
