The detection data of the liquid level meter 2 and the flow meter 4 are transmitted to the control device, and the control device judges the detection data of the liquid level meter 2 and the flow meter 4, that is, judges whether the liquid level detected by the liquid level meter 2 reaches the set liquid level, and whether the gas flow detected by the flow meter 4 reaches the set flow. When the liquid level detected by the liquid level meter 2 reaches the set liquid level, and the gas flow detected by the flow meter 4 reaches the set flow, the oil cylinder is controlled to stop, so as to facilitate the replacement of the seal of the oil cylinder.

[0032] Optionally, the probe of the liquid level meter 2 extends into the oil recovery tank 1 and is close to the bottom surface of the oil recovery tank 1. Thus, the liquid level meter 2 can detect the oil leakage even when the oil leakage is very small.

The liquid level gauge 2 is connected to the oil recovery tank 1 through a thread, and a first combined sealing gasket is provided between the liquid level gauge 2 and the oil recovery tank 1, which can prevent oil from flowing out of the gap between the oil recovery tank 1 and the liquid level gauge 2, and can also prevent external liquid or gas from flowing into the oil recovery tank 1.

The one-way valve 7 can allow gas to flow from the recovery oil tank 1 to the atmosphere. When gas enters the recovery oil tank 1 from the oil cylinder end cover through the pipeline, the pressure in the recovery oil tank 1 increases, thereby opening the one-way valve 7, and the gas flows out from the discharge main pipe 3. The one-way valve 7 is opened when there is a lower ejection pressure, and the excess gas in the recovery oil tank 1 can be discharged to the atmosphere at any time, and the external gas is prevented from being blown back into the recovery oil tank 1 through the discharge main pipe 3.

[0038] Optionally, the oil cylinder leakage recovery detection device further comprises a plug 6, and the recovery oil tank 1 is provided with an oil drain port, and the plug 6 can close or open the oil drain port.

[0039] Optionally, the recovery oil tank 1 is made of 304 stainless steel. The processing technology of the recovery oil tank 1 is folding and welding, and it is required that the recovery oil tank 1 has no leakage after welding.

[0040] Optionally, the float of the liquid level gauge 2 is made of plastic material. When gas flows into the recovery oil tank 1, there is a pressure difference between the pressure in the recovery oil tank 1 and the atmospheric pressure. The float of the liquid level gauge 2 will float up and down according to the pressure difference. The gas flow rate can be converted according to the position of the float, thereby obtaining the leakage amount.
