[0032] The present invention will be described in detail below with reference to specific embodiments. The following embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any form. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several changes and improvements can be made. These all belong to the protection scope of the present invention.

[0033] The present invention is a device for accurately monitoring liquid parameters in the case of mixed liquid with bubbles and the need to eliminate the interference of bubbles on the sensor after sampling.

[0034] This device uses the buoyancy principle and the basic principles of fluid mechanics. According to pressure and flow rate, the bubbles in the oil liquid are skillfully separated, with the pure liquid on one side for detection, the bubbles collected on the other side, and automatically discharged back to the original pipeline.

[0035] An oil - gas separation detection device mainly includes three parts: a box body, a cover, and a gas recovery and discharge device, namely a cavity.

[0036] An oil-gas separation monitoring device provided according to the present invention includes: a box body 1, a box cover 2, a T-shaped partition 3, an L-shaped partition 4, a cavity 5, an inlet 6, an outlet 7, a floating ball 8, a cavity inlet 9, and a cavity air outlet 10;

[0037] A sensor is installed on the box cover 2 to detect the oil liquid;

[0038] The inlet 6 is located on the first side surface of the box body 1;

[0039] The outlet 7 is located on the third side surface of the box body 1;

[0040] The first inner side surface of the box body 1 is connected to the T-shaped partition 3; the T-shaped partition 3 is located above the inlet 6; the a surface of the T-shaped partition 3 is connected in a curved surface, so that the oil liquid enters the box body 1 through the inlet 6, and the flow rate of the oil liquid passing through the T-shaped partition 3 gradually slows down; as the oil liquid flows in, the bubbles in the oil liquid accumulate at the c1 position;

[0041] The second inner side surface of the box body 1 is connected to the cavity 5; the cavity 5 is connected to the L-shaped partition 4; the b surface of the L-shaped partition 4 is connected in a curved surface; the L-shaped partition 4 is located above the T-shaped partition and is placed crosswise, forming two oil liquid channels, and the oil liquid flows through the two channels to the detection channel e;

[0042] The cavity 5 has a cavity inlet 9 and a cavity air outlet 10, and there is the floating ball 8 in the cavity 5. When there is gas in the cavity 5, the gas is normally discharged from the air outlet. When there is a preset amount of oil liquid in the cavity 5, that is, when the gas amount is relatively small and in a closed state, the floating ball 8 in the cavity 5 closes the cavity air outlet 10. Therefore, the normal oil liquid without bubbles flows from the c2 channel to the d channel, and the d channel to the e detection channel. It is exactly the detection area without the influence of bubbles.

[0043] Specifically, the cavity inlet surface of the cavity 5 is connected by a horizontal surface and an inclined surface.

[0044] Specifically, the included angle between the horizontal plane and the vertical plane of the L-shaped partition 4 is a preset value.

[0045] Specifically, a sensor is installed on the box cover 2, and there are 3 sensors. The sensors include: an oil temperature and humidity sensor 1a, an oil product quality sensor 2a, and a viscosity sensor 3a.

[0046] Specifically, the oil temperature and humidity sensor 1a is located in the b area;

[0047] The oil product quality sensor 2a is used to measure impurities in the oil and is located in the 3 area at the detection channel e; there will be a slight influence from bubbles.

[0048] The viscosity sensor 3a is used for measuring the viscosity of lubricating oil and is located in area 2 at the detection channel e. The influence of this bubble is relatively large, so the measurement is carried out in an environment with as few bubbles as possible.

[0049] At the outlet, through the simulation of three-dimensional design of fluid mechanics and multiple structure optimization design simulations, a relatively stable medium is finally formed in areas 2 and 3. After passing through the filtering effect of the front cavity, various bubbles in the pure oil liquid have been removed.

[0050] Specifically, the floating ball 8 is made of a stainless steel hollow ball. By calculating that the average density of the floating ball 8 is lower than the density of the oil liquid, it can float in the oil liquid to achieve the purpose of automatically opening and closing for exhaust.

[0051] Specifically, the material of the oil-gas separation detection device is aluminum alloy. This is mainly to facilitate precision machining so that various curved shapes can be conveniently machined.

[0052] Specifically, a precision-machined sealing strip is used to seal between the box cover 2 and the box body 1, and secondary stress points are preset and fixed dispersedly, making the equipment more airtight and safer.

[0053] In summary, for the oil liquid containing bubbles passing through this device, the bubbles and the pure oil liquid can pass through two channels respectively, thus avoiding the influence of bubbles on the detection accuracy of the sensor, and finally automatically returning the gas to the main channel without subsequent maintenance or harmful exhaust gas and other adverse consequences.
