油液中气泡还能引起系统振动和噪声的增加,以及泵的容积效率减低等不良影响。二、防治措施1.注重检查和维护防止外部气体进入系统,使用中应经常检查油箱油量情况是否正常,避免发生吸空现象,同时及时检查油液情况,避免油液变质;经常检查滤油器是否堵塞,以免油口压力过低而吸入空气; Bubbles in the oil can also cause system vibration and noise increases, as well as the pump to reduce the volumetric efficiency and other adverse effects. Second, prevention and treatment measures 1. Focus on inspection and maintenance to prevent external gases into the system, the use of fuel tank should always check the situation is normal, to avoid the phenomenon of suction, and timely inspection of oil situation, to avoid oil deterioration; frequent inspection of oil filter Whether the device is clogged, so as to avoid the oil pressure is too low and inhale the air;
