Description

Technical Field

[0001] This utility model relates to the field of oil and gas detection technology, specifically to an oil and gas vacuum degassing detection device. Background Technology

[0002] "Oil moisture content" refers to the water content in greases (such as lubricating oil, gear oil, hydraulic oil, etc.), and is a key indicator for measuring the purity and performance of oil. Its effects on oil include: decreased lubrication performance: moisture disrupts oil film stability, leading to direct friction between metal parts and accelerating wear (such as gear pitting and bearing corrosion). Additive failure: moisture reacts with additives in the oil (such as anti-wear agents and antioxidants), accelerating oil deterioration. Metal corrosion: moisture triggers electrochemical corrosion, shortening equipment lifespan (especially noticeable in steel components). Deterioration of low-temperature fluidity: moisture freezes at low temperatures, clogging oil passages or filters (such as low-temperature failures in hydraulic systems). Regularly testing the moisture content of gear oil allows for timely detection of problems and appropriate measures, such as replacing or treating the gear oil, to avoid a series of mechanical failures caused by moisture. Generally, a vacuum is drawn from the testing chamber, followed by pumping in an oil sample for degassing, and the humidity is measured using a humidity sensor. Simply drawing a vacuum is insufficient for adequate degassing, affecting the test results. Utility Model Content

[0020] Embodiments of this utility model:

[0021] like Figure 1 As shown, an oil and gas vacuum degassing detection device includes a working chamber 1, a sample inlet pipe, a vacuum pumping pipe, a temperature control component, an air extraction pipe, and a humidity sensor. One end of the sample inlet pipe is connected to the working chamber 1 for stable and quantitative sample injection; one end of the vacuum pumping pipe is connected to the working chamber 1 for extracting gas from the chamber and adjusting the vacuum level; one end of the air extraction pipe is connected to the vacuum pumping pipe and is used for sampling and waste discharge after detection.

[0022] Working chamber 1 is made of commonly used stainless steel cylinder body, which has high strength and uniform heat conduction. The two sides of the chamber wall are sealed by flanges. The chamber can be quickly evacuated to the predetermined vacuum level using the vacuum pipeline, creating conditions for the degassing process.

[0023] The sample inlet pipeline includes an inlet 7, an inlet regulating valve 6, an inlet solenoid valve 4, and an oil volumetric flow meter 5. The inlet regulating valve 6 is located between the inlet 7 and the oil volumetric flow meter 5. The inlet 7 is equipped with the inlet regulating valve 6 and the oil volumetric flow meter 5, which can accurately control the oil inlet volume and monitor it in real time.

[0026] The temperature control assembly includes a temperature controller, a temperature sensor, and a heater. The heater, such as an electric heating element, is located inside the working chamber 1 and is installed in the working chamber 1 to heat the interior of the working chamber 1. The temperature sensor is connected to the working chamber 1 to monitor the temperature inside the working chamber 1; in this embodiment, a PT100 temperature sensor is used. The temperature controller obtains the temperature information inside the chamber in real time through the connection to the temperature sensor and controls the operation of the heating element. A control switch is also provided, which is a protective element used to prevent the chamber from overheating and burning dry; it can trigger circuit disconnection if abnormal temperature is detected. The temperature control assembly can precisely adjust the temperature of the working chamber 1 according to the characteristics of different oil and gas samples, optimizing the degassing process.

[0027] A humidity sensor is connected to the working chamber 1 to monitor the humidity inside the working chamber 1. The humidity sensor is a through-hole laser humidity sensor that is inserted deep into the vacuum working chamber 1. Utilizing the principle of laser scattering, it can quickly and accurately measure the humidity in the gas after oil and gas degassing, exhibiting extremely high sensitivity and accuracy.

[0028] The working chamber 1 is also connected to a dew point sensor, a pressure sensor, and a temperature sensor. The dew point sensor monitors the dew point of the gas inside the chamber in real time, providing crucial data for determining the degree of gas dryness and degassing effect. The pressure sensor, installed on the wall of the working chamber 1, monitors pressure changes inside the chamber in real time and is used to calculate the dew point values ​​under pressurized and unpressurized conditions, offering high measurement accuracy and fast response. A temperature sensor (18B20) monitors the external ambient temperature in real time, providing a reference for overall temperature compensation; for distinction, this is referred to as the external temperature sensor.

[0029] The oil and gas vacuum degassing detection device also includes an extraction pipeline, one end of which is connected to the vacuum pipeline. The extraction pipeline includes an external extraction solenoid valve 11 and an extraction port quick plug 12.

[0030] The oil and gas vacuum degassing detection device also includes a sampling pipeline. One end of the sampling pipeline is connected to the bottom of the working chamber 1. The sampling pipeline includes a sampling regulating valve 17 and a sampling port 16. The sampling port 16 can be connected to the sampling bottle 15 for sampling. Two tubes can be connected to the cap of the sampling bottle 15. One tube is connected to the sampling port 16, and the other tube is indirectly connected to the suction pipeline, which provides the suction power.

[0031] The other pipe mentioned above is connected to the air extraction pipe through the waste extraction pipe. The waste extraction pipe includes an external air extraction solenoid valve 11, an air extraction port quick connector 12, a waste liquid collection bottle 13, and an external isolation valve 14.

[0032] The oil and gas vacuum degassing detection device also includes a sampling pipeline. One end of the sampling pipeline is connected to the working chamber 1. The sampling pipeline includes a sampling regulating valve 17 and a sampling port 16. The sampling port 16 is connected to the sampling bottle 15 for sampling. The quick-connect plug 12 of the gas extraction port is connected to a waste liquid collection bottle 13. The waste liquid collection bottle 13 is connected to a waste extraction pipeline. The waste extraction pipeline can be connected to the sampling bottle 15. An external isolation valve 14 is provided on the waste extraction pipeline.

[0033] The working chamber 1 is connected to an air inlet pipe, including an air inlet 18 and an air inlet regulating valve 19. The air inlet regulating valve 19 can be used to precisely control the air inlet flow rate. During the waste discharge operation after the test is completed, the air inlet pipe can be used to introduce outside air into the working chamber 1, which is conducive to the discharge of waste liquid in the working chamber 1.

[0034] All of the above-mentioned solenoid valves, vacuum pumps, sensors, and temperature controllers are connected to the control host.

[0035] The working principle of the oil and gas vacuum degassing detection device of this utility model is as follows:

[0036] (1) Degassing

[0037] Heating of the working chamber 1 is initiated, and the vacuum pump is started. Air is extracted from the working chamber 1 via the suction regulating valves 10 and 9 to create a dry vacuum environment. The vacuum pump automatically stops when the preset vacuum level and humidity are reached. The sample injection solenoid valve 4 opens, and the oil sample is quantitatively introduced into the working chamber 1 by atmospheric pressure through the oil sample bottle 8, the sample inlet 7, the sample injection regulating valve 6, and the oil volumetric flow meter 5. Simultaneously, other unrelated valves are closed. Under the action of the temperature controller, the heating band temperature is adjusted according to the characteristics of the oil and gas sample, allowing dissolved water in the oil and gas to escape under vacuum and suitable temperature conditions. During this process, the dew point sensor monitors the gas dew point in real time. When the dew point reaches a stable value and meets the expected value, degassing is basically complete, and heating of the working chamber 1 is stopped. The oil sample bottle 8 is 1L.

[0038] (2) Detection

[0039] After degassing is complete, a humidity sensor measures the gas humidity, and a pressure sensor monitors the pressure inside the chamber in real time. The control unit collects data from each sensor, analyzes and processes it, and displays the measurement results on the screen in real time. For further analysis, a sample can be collected from the sampling port 16 by opening the sampling regulating valve 17.

[0040] (3) Sampling

[0041] The vacuum pump and external suction solenoid valve 11 are opened, and samples are drawn into the sampling bottle 15 through the suction regulating valve 9, external suction solenoid valve 11, waste liquid suction port, external isolation valve 14, sampling port 16, and sampling regulating valve 17. As described earlier, the two tubes of the sampling bottle 15 have one inlet and one outlet for sampling. The function of the external isolation valve 14 is to quickly stop the sampling process by closing it after it is completed. The sampling bottle 15 uses 10ml bottles.

[0042] In other embodiments, the quick-connect plug 12 of the suction port can be directly connected to another tube of the sampling bottle 15 for direct suction, without passing through the waste liquid collection bottle 13 and the external isolation valve 14.

[0043] (4)Drainage

[0044] Open the inlet regulating valve 19, the vacuum pump, and the external suction solenoid valve 11. Waste liquid is discharged into the waste liquid collection bottle 13 through the suction regulating valve 9, the external suction solenoid valve 11, the quick-connect fitting 12, the external isolation valve 14, the sampling port 16, and the sampling regulating valve 17. At this time, the sampling bottle 15 has been removed, and the waste extraction pipeline can be directly connected to the sampling port 16. The waste liquid collection bottle 13 is 1L.
