The control method is used for controlling the oil-water separator 10 by obtaining a first height signal indicative of the height of the water level outputted by the first liquid level sensor 133 disposed in the second chamber 122, and controlling the first valve 131 to close according to the first height signal.
The oil-water separation system provided by the embodiment is further described as follows:
referring to fig. 1, in the present embodiment, a body 100 of an oil-water separator 10 includes a housing 120 and a filter element 110 disposed in the housing 120. Specifically, a separation chamber for accommodating the filter element 110 and an oil-water chamber arranged on the lower side of the separation chamber are arranged in the housing 120, the separation chamber is communicated with the oil-water chamber, an oil inlet 123 and an oil outlet 124 are formed in the housing 120, and the oil inlet 123 and the oil outlet 124 are communicated through the separation chamber.

The level sensor is electrically connected to the controller, which is electrically connected to the first valve 131. The liquid level sensor transmits a signal representing the detected height of the water level to the controller, and the controller controls the first valve 131 to open and close according to the signal.
Specifically, when the water level reaches the first preset height, the controller controls the first valve 131 to close, so as to effectively prevent the water in the second chamber 122 from affecting the fuel system, and enable the oil-water separator 10 to perform the drainage operation without stopping the engine. Meanwhile, the controller is electrically connected to the second valve 132 to control the second valve 132 to open, so that the water in the second chamber 122 is discharged through the second valve 132, thereby achieving automatic water discharge of the oil-water separator 10. When the water level reaches the second preset height, the water discharge is completed, and the controller controls the first valve 131 to be opened and simultaneously controls the second valve 132 to be closed.
Further, the liquid level sensor includes a first liquid level sensor 133 and a second liquid level sensor 134 disposed within the second chamber 122, and both the first liquid level sensor 133 and the second liquid level sensor 134 are electrically connected to the controller.
