裝載機液壓油箱往外噴油的主要原因是油液中含有大量氣泡，使油液的可壓縮性增加。由于油液流回油箱時，從高壓突然降為低壓，混入油液中的空氣在油箱內急劇膨脹，油箱內的壓力高于大氣壓力，使油液混同空氣一起從油箱通氣孔排出，形成噴油現象。山東裝載機出現噴油現象時，應重點檢查油液油箱至工作泵或轉向泵管路的密封性，以及油泵本身是否漏氣。
The main reason that the hydraulic oil tank of the hydraulic oil tank in Shandong is the oil is a large number of bubbles in the oil liquid, so that the compressibility of the oil can be increased. Because of the oil liquid flows back to the tank, from the high pressure suddenly drop for low voltage, mixed with oil in the air in the tank in the rapid expansion of, the tank pressure higher than atmospheric pressure, oil pooling air together from the tank vent discharge,the formation of the phenomenon of injection. When the fuel injection phenomenon occurs in Shandong loader, it should be focused on checking the sealing performance of the oil tank to the working pump or the steering pump line, and whether the pump itself is leaking.

裝載機在回油油路中，通常裝有濾油器，如果濾油器脫落，也可能出現噴油現象，這種噴油現象中噴出的油，泡沫不多，這是與工作液壓系統中混入空氣的區別。
Shandong loader in the oil return path, usually equipped with oil filter, if expulsion of oil filter may also appear the phenomenon of oil injection, ejected from the injection phenomena in oil, foam is not much. This is working hydraulic system mixed with air, and difference.
