By observing the bubbles or foams in the detection liquid, it can be more intuitive to judge whether there is a leak in the oil cylinder. This method can reduce the misjudgment caused by visual errors or misjudgments. Immersing the oil cylinder in the detection liquid for detection can shorten the detection time. Compared with detection in the air, the detection liquid can reflect the leakage more quickly, thereby improving the detection efficiency. By using the detection liquid for detection, the detection cost can be reduced. The detection liquid can be reused and only needs to be replenished regularly, thereby reducing the consumption and purchase cost of the detection liquid. BRIEF DESCRIPTION OF THE DRAWINGS
