Description

Technical Field

[0001] This utility model relates to the field of lubricating oil performance testing technology, and is particularly applicable to testing devices for the demulsification performance of vacuum pump oil in industries such as food and pharmaceuticals. Background Technology

[0002] Poor demulsification properties of vacuum pump oil can trigger a series of chain reactions. Emulsification reduces the sealing performance of the oil, leading to a drop in vacuum levels; it also reduces the oil film's load-bearing capacity, causing wear on the pump body and bearings. In the food industry, especially in food packaging and pharmaceuticals, some moisture in the system is continuously drawn into the vacuum pump chamber along with the gas. Emulsified pump oil is prone to bacterial growth, contaminating the production environment and posing serious food safety risks. Therefore, the demulsification properties of vacuum pump oil are particularly important.

[0003] Currently, demulsibility testing mainly relies on the ASTM D1401 standard, which uses a static observation method. This test uses a 1:1 oil-to-water ratio, which does not match actual working conditions. Furthermore, after the test, the oil layer is usually opaque, indicating water-in-oil (W / O) emulsification. In this case, the water content in different oil layers can only be compared visually.

[0004] Moreover, there is currently no dedicated testing equipment for the demulsification properties of oils, making it impossible to achieve a continuous and dynamic testing effect. Utility Model Content

Detailed Implementation

[0038] This embodiment aims to provide a fast and effective device for dynamically testing the demulsibility of vacuum pump oil, which includes an oil emulsification unit A, an oil detection unit B, and a fluid delivery mechanism C.

[0039] The oil emulsification unit A emulsifies the oil and then sends the emulsified oil to the oil testing unit B via the fluid conveying mechanism C. The oil testing unit B tests the oil and then sends the tested oil back to the oil emulsification unit A.

[0040] The specific structure is as follows:

[0041] Oil emulsification unit A includes a first oil tank 1, an emulsification mechanism and a water inlet pipe 7;

[0042] Oil testing unit B includes a second oil tank 2 and a light transmittance tester 10;

[0043] The first oil tank 1 is a cylindrical glass oil tank, a visible oil tank with a heater, and a temperature control range of room temperature to 120℃; the opening is equipped with a cover to prevent dust and moisture loss from the system, and it contains industrial fluid 6.

[0044] The second oil tank 2 is a rectangular glass oil tank with graduations on the outer surface of the shell; the opening on it can also be equipped with a cover to prevent dust and moisture loss from the system.

[0045] The emulsifying mechanism is fixed in the center of the dust cover and installed in the first oil tank 1. It is a traditional mixer structure with an adjustable speed (1000-3000rpm). After installation, the stirring paddle 3 is close to the bottom surface of the first oil tank 1 to achieve a better stirring effect. The motor 8 that controls the stirring paddle 3 to stir is located outside the upper surface of the first oil tank 1 and is powered by the power line 12.

[0046] The water inlet pipe 7 is a glass tube. One end of it passes through the top surface of the first oil tank 1 and enters the interior of the first oil tank 1, while the other end is connected to the water supply equipment, thereby achieving the effect of filling the first oil tank 1 with water.

[0047] Considering the requirements for the oil / water ratio during the testing process, a flow meter can also be installed on the water inlet pipe 7 to monitor and control the amount of water entering the system.

[0048] Furthermore, considering that the oil content may be adjusted during the testing process, the oil emulsification unit also includes an oil inlet pipe; one end of the oil inlet pipe passes through the top surface of the first oil tank and enters the interior of the first oil tank, while the other end is connected to the oil supply container. Similarly, a flow meter can also be installed on the oil inlet pipe.

[0049] The fluid delivery mechanism 3 includes a fluid delivery pipe 5 and a fluid pump 4;

[0050] The fluid delivery pipe 5 is a polyethylene pipe, one end of which penetrates the top surface of the first oil tank and enters the interior of the first oil tank 1 near the bottom surface, and the other end penetrates the top surface of the second oil tank 2 and enters the interior of the second oil tank 2 near the bottom surface.

[0051] The fluid pump 4 is installed on the fluid delivery pipe 5 and directionally delivers the fluid in the first oil tank 1 to the second oil tank 2, thereby realizing the preparation of inputting the 6-1 to be tested into the second oil tank 2 for testing.

[0052] The second oil tank 2 is connected to the first oil tank 1 through the return channel 9;

[0053] The return channel 9 is a polyethylene pipe, with the fluid inlet located on one side of the second oil tank 2 and the fluid outlet located on the other side of the first oil tank 1.

[0054] In this experimental example, the second oil tank 2 has a capacity of 300 ml and an outlet at the 200 mark. Fluid flows back to the first oil tank 1 from the outlet of the second oil tank 2 through a polyethylene pipe due to the pressure difference.

[0055] The transmittance tester 10 is installed at the fluid inlet to detect the transmittance of the fluid and transmits the data to the device end via the transmission line 11.

[0056] The function and effect of this embodiment:

[0057] 1. The water content and water quality of the oil can be controlled according to the on-site working conditions; water can also be added continuously to test the maximum water content of the oil when it fails.

[0058] 2. The oil's anti-emulsification ability can be evaluated online, that is, the oil becomes cloudy after emulsification and gradually becomes transparent after standing. By testing the transparency, the water separation ability of the oil can be determined.
