This seemingly good measure has buried a very big hidden danger for the safety of the whole hydraulic system.

自動上料攪拌車排氣管會將油箱里的熱氣排出，在瓶子里凝結成水，平時沖洗水和雨水也會順著氣管流進瓶子里，油箱冷卻時會將水分通過排氣管倒吸進油箱。參進水分的液壓油很快就會變質，成為乳白色，通常被稱為油液乳化。

The exhaust pipe of the automatic feeding mixer truck will discharge the hot gas in the oil tank and condense into water in the bottle. Usually, the flushing water and rainwater will also flow into the bottle along the air pipe. When the oil tank is cooled, the water will be sucked back into the oil tank through the exhaust pipe. The hydraulic oil with water will soon deteriorate into milky white, which is usually called oil emulsion.

乳化后的液壓油潤滑性能和壓縮性能會嚴重下降，引起一系列的問題，輕則泵馬達內泄工作無力，各膠圈和油封磨損漏油。泵軸端油封漏油，控制閥膠圈磨損漏油，重則會使液壓泵和馬達柱塞滑靴和配油盤磨損甚至報廢。

The lubricating performance and compression performance of emulsified hydraulic oil will be seriously reduced, resulting in a series of problems. At least, the internal leakage of pump Mada is weak, and each rubber ring and oil seal are worn and leaked. The oil seal at the pump shaft end leaks oil, the rubber ring of the control valve is worn and leaks oil, which will seriously wear and even scrap the plunger slippers and oil distribution discs of the hydraulic pump and motor.

自動上料攪拌車泵內部嚴重磨損更好的解決辦法就是將排氣管垂直伸到車底下，讓排出的油自然滴到地上。不要將排氣管打結和纏繞。還掛著水瓶的朋友們，趕緊把瓶子去掉吧！！

The pump of the automatic feeding mixer truck is seriously worn. The better solution is to extend the exhaust pipe vertically under the truck and let the discharged oil drip naturally to the ground. Do not knot or wind the exhaust pipe. Friends who still hang water bottles, get rid of the bottles quickly!!

好在現在的自動上料攪拌車散熱器都進行了改良，在油箱側面加裝了一個油液回收盒，可以有效解決污染的問題，盒子容量有限，大伙可要記得經常檢擦，及時將里面積存的油放掉，尤其是新車剛使用和換完油后的幾天是更容易溢油的。

Fortunately, the radiator of the automatic feeding mixer truck has been improved. An oil recovery box has been installed on the side of the oil tank, which can effectively solve the problem of pollution. The box capacity is limited. Everyone should remember to check and wipe it frequently and drain the accumulated oil in time, especially in the days after the new car has just been used and changed.
