Description

Technical Field

[0001] This utility model relates to the field of oil monitoring technology, and in particular to an online oil monitoring device capable of defoaming. Background Technology

[0002] During operation, the hydraulic circuits of mechanical equipment experience rapid pressure drops and oil falls from heights, causing air and air bubbles to mix in due to damage to the oil pump inlet pipe and other factors. The presence of these bubbles poses a risk to the normal lubrication lifespan of the mechanical equipment and also affects the detection of oil quality and particulate matter purity by monitoring equipment. Since bubbles frequently appear in the hydraulic circuit, their presence directly impacts the accuracy of contamination sensors. Therefore, eliminating the impact of bubbles in the hydraulic circuit on contamination sensor detection is crucial. Existing defoaming devices on the market include vibration and ultrasonic defoaming devices. However, these devices are relatively complex to use or require specialized equipment, resulting in high application costs.

[0003] Therefore, existing technologies have shortcomings and need to be improved. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an online oil monitoring device that can defoam, thereby solving the problem that the presence of air bubbles in the oil circuit affects the detection accuracy of the oil sensor.

[0005] The technical solution of this utility model is as follows: An online oil monitoring device capable of defoaming is provided, comprising: a chassis, an oil inlet, an oil outlet, and several pipes, with a defoaming box, an oil sensor, a booster pump, and a first one-way regulating valve respectively installed within the chassis; the two ends of the booster pump are connected to the oil inlet and the defoaming box respectively via pipes, and the two ends of the oil sensor are connected to the defoaming box and one end of the first one-way regulating valve respectively via pipes, with the other end of the first one-way regulating valve connected to the oil outlet; the defoaming box includes: a top bubble retention area and a lower oil containing area, with a pipe connecting the defoaming box and the oil sensor extending into the lower oil containing area. Preferably, the oil inlet and oil outlet are installed on the outer surface of the chassis, and the oil sensor is at least one of commonly used oil sensors such as: abrasive particle sensors, viscosity sensors, trace moisture sensors, dielectric constant sensors, temperature sensors, PPM value sensors, and contamination sensors.

[0006] The oil flows into the booster pump through the inlet, which then draws the oil into the defoaming box. Since the defoaming box is divided into a top bubble retention area and a lower oil receiving area, bubbles tend to move towards the bubble retention area, while the oil is stored in the lower oil receiving area. The booster pump continuously pumps in oil, increasing the pressure within the defoaming box. The oil in the lower oil receiving area then flows through a pipe to the oil sensor and the first one-way regulating valve. When the oil pressure exceeds the threshold pressure of the first one-way regulating valve, the oil overflows the valve and flows to the outlet, allowing the oil sensor to detect the oil. Because the bubble retention area in the defoaming box retains bubbles, preventing them from entering the oil sensor, it avoids the influence of bubbles on the oil sensor's detection accuracy, thus improving detection precision.

[0007] Furthermore, the top bubble retention area is provided with a slope. The slope allows bubbles to be retained better in the top bubble retention area.

[0008] Furthermore, the online oil monitoring device capable of defoaming also includes: a second one-way regulating valve, the two ends of which are connected to the top bubble retention area and the oil outlet respectively via pipelines; the conduction pressure of the second one-way regulating valve is greater than the conduction pressure of the first one-way regulating valve. When a blockage occurs in the pipeline where the first one-way regulating valve is located, the booster pump will continue to pump oil into the defoaming box. To avoid damage to the booster pump due to excessive pressure, when the pressure inside the defoaming box is greater than the conduction pressure of the second one-way regulating valve, the second one-way regulating valve will open, and bubbles and oil will flow into the oil outlet through the second one-way regulating valve, reducing the pressure inside the defoaming box and preventing damage to the booster pump.

[0009] Furthermore, the pipe connecting the second one-way regulating valve and the top bubble retention area is installed at the top of the top bubble retention area.

[0010] Furthermore, the online oil monitoring device capable of defoaming also includes a three-way valve, wherein the oil outlet is connected to the first one-way regulating valve and the second one-way regulating valve respectively via the three-way valve.

[0011] Furthermore, the online oil monitoring device capable of defoaming also includes: a third one-way regulating valve and an overflow port. The two ends of the third one-way regulating valve are connected to the top bubble retention area and the overflow port respectively via pipes. The conduction pressure of the third one-way regulating valve is greater than the conduction pressure of the second one-way regulating valve. Similarly, when the pipes containing the first and second one-way regulating valves experience blockage, the booster pump will continue to pump oil into the defoaming box. To avoid damage to the booster pump due to excessive pressure, when the pressure inside the defoaming box exceeds the conduction pressure of the third one-way regulating valve, the third one-way regulating valve will open, allowing bubbles and oil to flow into the overflow port through the third one-way regulating valve, reducing the pressure inside the defoaming box and preventing damage to the booster pump.

[0012] Furthermore, the pipe connecting the third one-way regulating valve and the top bubble retention area is installed at the top of the top bubble retention area.

[0013] Furthermore, the online oil monitoring device capable of defoaming also includes: a middle partition installed within the defoaming box, with a through hole in the middle of the partition. The middle partition divides the lower oil receiving area into a first oil area and a second oil area, and the first oil area and the second oil area are connected. A pipe connecting to the oil sensor extends into the first oil area, and a pipe connecting to the booster pump is connected to the second oil area. The through hole allows oil to flow from the second oil area to the first oil area, and the middle partition prevents air bubbles from flowing into the first oil area.

[0014] Furthermore, the online oil monitoring device capable of defoaming also includes a main control board, which is electrically connected to the booster pump and the oil sensor.

[0015] Furthermore, the online oil monitoring device capable of defoaming also includes: a signal interface installed on the surface of the chassis, and the main control board is electrically connected to the signal interface.

[0016] By adopting the above solution, this utility model provides an online oil monitoring device that can eliminate bubbles. By eliminating bubbles in the oil circuit through the defoaming box, the influence of bubbles on the detection of oil sensors can be avoided, thereby improving the accuracy of online oil monitoring for oil quality detection.

Preferably, the oil inlet 11 and oil outlet 12 are installed on the outer surface of the housing 10, and the oil sensor 14 is a commonly used oil sensor such as at least one of the following: metal abrasive sensor, viscosity sensor, trace moisture sensor, dielectric constant sensor, temperature sensor, PPM value sensor, and contamination sensor.

[0020] Oil flows into booster pump 15 through inlet 11. Booster pump 15 draws the oil into defoaming box 13. Since defoaming box 13 is divided into a top bubble retention area 17 and a lower oil receiving area, bubbles tend to move towards the bubble retention area, while the oil is stored in the lower oil receiving area. The booster pump continuously pumps in oil, increasing the pressure within defoaming box 13. The oil in the lower oil receiving area then flows through a pipe to oil sensor 14 and first one-way regulating valve 16. When the oil pressure exceeds the threshold pressure of the first one-way regulating valve 16, the oil overflows the valve and flows to outlet 12, allowing oil sensor 14 to detect the oil. Because the bubble retention area in defoaming box 13 can retain bubbles, preventing them from entering oil sensor 14, the influence of bubbles on oil detection by oil sensor 14 is avoided, thus improving detection accuracy.

[0021] In this embodiment, the top bubble retention area 17 is provided with a slope 18. The slope 18 allows bubbles to be better retained in the top bubble retention area 17.

When a blockage occurs in the pipeline where the first one-way regulating valve 16 is located, the booster pump 15 will continue to pump oil into the defoaming box 13. To avoid damage to the booster pump 15 due to excessive pressure, when the pressure in the defoaming box 13 is greater than the conduction pressure of the second one-way regulating valve 19, the second one-way regulating valve 19 will open, and the bubbles and oil will flow into the oil outlet 12 through the second one-way regulating valve 19, reducing the pressure in the defoaming box 13 and preventing damage to the booster pump 15.

[0023] In this embodiment, the pipe connecting the second one-way regulating valve 19 and the top bubble retention area 17 is installed at the top of the top bubble retention area 17.

[0025] In this embodiment, the online oil monitoring device capable of defoaming further includes: a third one-way regulating valve 21 and an overflow port 30. The two ends of the third one-way regulating valve 21 are connected to the top bubble retention area 17 and the overflow port 30 respectively via pipes. The conduction pressure of the third one-way regulating valve 21 is greater than the conduction pressure of the second one-way regulating valve 19. Similarly, when the pipes containing the first one-way regulating valve 16 and the second one-way regulating valve experience blockage, the booster pump 15 will continue to pump oil into the defoaming box 13. To avoid damage to the booster pump 15 due to excessive pressure, when the pressure inside the defoaming box 13 exceeds the conduction pressure of the third one-way regulating valve 21, the third one-way regulating valve 21 will open, allowing bubbles and oil to flow into the overflow port 30 through the third one-way regulating valve 21, reducing the pressure inside the defoaming box 13 and preventing damage to the booster pump 15. In this embodiment, the overflow port 30 and the oil outlet 12 are located above the oil inlet 11.

[0026] In this embodiment, the pipe connecting the third one-way regulating valve 21 and the top bubble retention area 17 is installed at the top of the top bubble retention area 17.

[0027] In this embodiment, the online oil monitoring device capable of defoaming further includes: a middle partition 22 installed within the defoaming box 13, with a through hole 23 in the middle of the middle partition 22. The middle partition 22 divides the lower oil receiving area into a first oil area 24 and a second oil area 25, and the first oil area 24 and the second oil area 25 are connected. A pipe connecting the oil sensor 14 extends into the first oil area 24, and a pipe connecting the booster pump 15 is connected to the second oil area 25. The through hole 23 allows oil to flow from the second oil area 25 to the first oil area 24, and the middle partition 22 prevents air bubbles from flowing into the first oil area 24.

[0028] In this embodiment, the online oil monitoring device capable of defoaming further includes a main control board 26, which is electrically connected to the booster pump 15 and the oil sensor 14.

[0029] In this embodiment, the online oil monitoring device capable of defoaming further includes: a signal interface 27 installed on the surface of the chassis 10, and the main control board 26 is electrically connected to the signal interface 27.
