Description
Technical Field
The utility model relates to a sensor specifically is an oil-water separation sensor.
Background
At present, the leakage detection of the double-layer oil tank mostly adopts a pressure (vacuum) detection method, which is a method of adopting compressed gas (vacuumizing) in a completely sealed annular gap space to generate certain pressure (vacuum degree) in the gap space, and then the integrity of the oil tank is detected by monitoring the change of the pressure (vacuum degree) in the gap space, thereby realizing the detection of the leakage at any position of the inner wall and the outer wall of the double-layer oil tank and ensuring that the oil product is found before leaking to the environment.
The detection method has the greatest advantages that the detection method has high safety and can ensure that the leakage accident can be detected before the oil product enters the environment. However, the detection system is complex, the sealing performance of the system is high, the applied pressure or vacuum is easy to escape or attenuate through a connecting part, and when the attenuation reaches an alarm point, an alarm device gives false alarm.

Detailed Description
The technical solution of the present patent will be described in further detail with reference to the following embodiments.
Example 1
Referring to fig. 1-3, the present embodiment provides an oil-water separation sensor, which includes a cable 2, a filler 3, a metal shell 4 and an inductive probe 5; an induction probe 5 is arranged on the outer side of the metal shell 4, and a sensor and a controller which are electrically connected are arranged in the metal shell 4; the cable 2 electrically connected with the controller comprises four wires 1; a filler 3 is filled between the cable 2 and the metal shell 4; the four wires 1 are respectively red, black, green and yellow, and the red, black, green and yellow are respectively connected with +5V, GND, output and reserve.
Further, the material of the filler 3 is not limited, and in this embodiment, the filler 3 is preferably epoxy resin.
Further, the material of the cable 2 is not limited, and in this embodiment, preferably, the cable 2 is a TRVV oil-resistant bending-resistant cable.
Furthermore, the material of the metal shell 4 and the inductive probe 5 is not limited, and in this embodiment, the material of the metal shell 4 and the material of the inductive probe 5 are preferably SS304 and PA12, respectively.
The working principle of the embodiment is as follows: the different characteristics of three different media of oil, water, air are utilized, corresponding materials are effectively distinguished, different signals are correspondingly output, and the controller can distinguish the state of the medium detected by the current position sensor. The method is realized by arranging a detection vertical pipe which is communicated with a space from a longitudinal central line at the top of the oil tank, installing the sensor at the lower part of the vertical pipe and is used for detecting the medium change in the space so as to detect the integrity of the oil tank, and by matching with a vacuum detection method, the detection of leakage of the inner tank and the outer tank of the double-layer oil tank can be realized, and the state of the medium (air, water and oil) at the bottom of the tank can be monitored in real time.
It should be noted that, as is obvious to a person skilled in the art, the invention is not limited to details of the above-described exemplary embodiments, but can be embodied in other specific forms without departing from the spirit or essential characteristics thereof.
