Description

Technical Field

[0001] The utility model relates to the technical field of oscillating degassing, and particularly relates to an oil product oscillating degassing detection device. Background Art

[0002] The oil product oscillating degassing device, also known as a degassing oscillator or a multi-functional oscillator, can meet the requirements of constant temperature and timed oscillation operations, and is used for constant temperature and timed heating, oscillation, and degassing of various liquids in the laboratory. In oil product analysis, such a device can effectively help analyze the combined content of dissolved gases in the oil. For example, a degassing device, a degassing method, and a gas detection system for transformer oil disclosed in the invention patent with the authorization announcement number CN115235855B respectively provide a first gas and transformer oil to a degassing container through a gas source storage module and an oil inlet unit, and realize the mixing of the transformer oil and the first gas through the vibration generated when the gas source driving element works, improve the mixing efficiency of the transformer oil and the first gas, and then pump the gas to be measured in the degassing container into a collection container for subsequent analysis of the gas to be measured. This degassing device mainly realizes the degassing of transformer oil and is used to detect the gas component situation contained therein.

[0003] In addition to the above detection requirements for transformer oil, for some other oil products, the humidity of the oil products needs to be detected.

Excessive water content in the oil product may cause problems such as oil oxidation and corrosion, thereby affecting the normal operation and service life of the equipment. At present, there is no complete device for detecting the humidity of oil product oscillating degassing.

The inner and outer housings 41 are nested and detachably installed to form a box structure.

[0040] The oscillator 45 is located below the inner housing 42. An oscillation plate 43 is provided in the inner housing 42. The oscillation plate 43 is connected to the oscillator 45. The degassing unit 22 and the air inlet unit 11 are located on the oscillation plate 43.

The flow controller 5 controls the total gas flow. After passing through the three-way joint 6, the gas is divided into two branches. One branch passes through the first intake valve 7, the drying port 8, and the first exhaust valve 10 and enters the right side of the intake unit 11, that is, the intake cavity, to dry the internal cavity and then is discharged through the first exhaust valve 10 and the exhaust port 9. The other branch passes through the pressurizing solenoid valve 25 and the second intake valve 23 and enters the right side of the degassing unit 22 to dry the internal cavity of the degassing unit 22 and then is discharged through the second exhaust valve 24 and the exhaust port 9. After the intake unit 11 and the degassing unit 22 are dried, a certain amount of dry gas enters the right side of the intake unit 11. After the humidity value is measured and recorded by the humidity sensor 14, it enters the left side of the degassing unit 22 through the second stop valve 15, the four-way joint 16, the intake flowmeter 18, and the intake valve 21, and is measured and recorded by the intake flowmeter 18. The oil sample to be measured enters the left side of the degassing unit 22 through the oil sample container 34, the oil inlet 33, the oil inlet valve 32, the oil sample pump 31, the liquid flowmeter 30, the oil sample inlet valve 29, and the first stop valve 28. The oscillator 45 works, and after high-temperature oscillation, the oil sample is discharged through the oil discharge valve 27 and the oil discharge port 26. The gas to be measured enters the right side of the intake unit 11 through the outlet valve, the outlet flowmeter 19, the four-way joint 16, and the second stop valve 15, and is measured and recorded by the outlet flowmeter 19. Then, the humidity value is measured and recorded by the humidity sensor 14, and then is discharged through the first exhaust valve 10 and the exhaust port 9. By calculating the two humidity values and the volume, the humidity of the oil sample to be measured can be obtained.
