Description

Technical Field

[0001] This utility model relates to the detection of oil contamination levels, specifically to an auxiliary defoaming device for detecting oil contamination levels. Background Technology

[0002] Oil contamination detection is widely used in the industrial field and is an important means of fault detection and prevention for many industrial machines during use. Common contamination detectors mainly use the principles of light shielding, light scattering, or laser imaging technology. During contamination detection, the oil sample to be tested comes into contact with air during shaking. A large amount of gas mixes with the oil sample, generating bubbles. Because the light transmittance of the bubbles differs from that of the oil, the bubbles are counted as solid particulate contaminants during the detection process, causing errors in the detection results.

[0003] Based on the timing of their formation, bubble formation can be mainly categorized into two types: The first type is suspended bubbles formed during the oil sample mixing process, where gas mixes with the oil sample and remains suspended in the middle of the sample. The second type is mainly formed during the oil sample shaking process, where dissolved gases in the oil sample precipitate out due to the negative pressure in the sample inlet tube of the detection device. In conventional oil contamination testing, the defoaming and degassing devices typically use ultrasonic degassing to eliminate bubbles. That is, during testing, an ultrasonic cleaner is first used to vibrate the oil sample under water to eliminate bubbles. This method is effective at eliminating the first type of bubbles but is less effective at eliminating the second type. Utility Model Content

[0004] In view of the above problems, this utility model proposes an auxiliary defoaming and degassing device for detecting oil contamination.

[0005] The technical solution of this utility model:

[0006] An auxiliary defoaming and degassing device for oil contamination detection includes a pressure tank, an air filling pump, an air extraction pump, and a conduit. The pressure tank has an air filling port and an air extraction port. The air filling pump is connected to the air filling port, and the air extraction pump is connected to the air extraction port. A purification bottle is placed inside the pressure tank, and the conduit is inserted into the pressure tank. An air filling valve is installed at the air filling port, and an air extraction valve is installed at the air extraction port. A valve is installed on the conduit. The conduit is connected to the sample inlet tube of an oil contamination detector. The auxiliary defoaming and degassing device also includes a purification bottle with an opening. The purification bottle is placed inside the pressure tank and filled with the oil to be tested. The conduit extends from the opening of the purification bottle into the purification bottle and to the bottom of the purification bottle.

[0007] To further refine the above technical solution, the auxiliary defoaming and degassing device also includes a pressure gauge, which is installed on the pressure tank to monitor the pressure in the pressure tank in real time.

[0008] To further refine the above technical solution, the pressure gauge is a pressure gauge with a safety valve.

[0009] To further refine the above technical solution, the pressure tank is provided with an exhaust port; the exhaust port is equipped with an exhaust valve.

[0010] To further refine the above technical solution, the pressure tank is a pressure tank with a quick-release lock; the conduit is located on the pressure tank opening cover and passes through the pressure tank opening cover.

[0011] Further refining the above technical solution, the opening of the purification bottle is located at the top; the air filling port and air extraction port are located at the lower part of the side wall of the pressure tank; thus, when pressure is supplied to the pressure tank, the gas being filled does not blow directly into the purification bottle.

[0012] The advantages of this invention are its reasonable design and simple structure. The air pump and the vacuum pump work together to create a vacuum before oil contamination detection, forming a negative pressure in the pressure tank. This causes the (first type) bubbles in the oil to be tested to expand and burst. During oil contamination detection, pressure is supplied to the pressure tank, changing the negative pressure state in the sample inlet tube of the oil contamination detector to a pressurized state. This effectively suppresses the generation of (second type) bubbles in the oil to be tested, resulting in good defoaming effect and improved accuracy of oil contamination detection.

[0016] Inject the oil to be tested, liquid 2, into purification bottle 1-10, shake well, and place it into pressure tank 1-1 (with the pressure tank cap open). Insert tubing 1-4 from the top opening of purification bottle 1-10 into the bottom (of the oil to be tested, liquid 2). Connect tubing 1-4 to the inlet tube 3-1 of the contamination detector. Close the inflation valve 1-6, exhaust valve 1-8, and valve 1-9. Open the suction valve 1-7 and start the suction pump 1-3 to create a vacuum, forming a negative pressure inside pressure tank 1-1.

Close the suction valve 1-7 and open the inflation valve 1-6 and valve 1-9 (while the exhaust valve 1-8 remains closed).
