Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, and specifically relates to an airtightness detection device for an oil-gas separator. Background Technology

[0002] Considering the working environment of oil-gas separators, which are typically subjected to high temperature and high pressure, leaks of high-temperature, high-pressure gases or oil mists can occur if the seal is not tight, leading to decreased efficiency or dangerous situations. Furthermore, modern environmental regulations have strict emission requirements; leaks can cause emissions to exceed standards, preventing the equipment from passing environmental certification and affecting market access. Therefore, sealing tests are necessary during the production of oil-gas separators. Current technology often uses the water immersion method (bubble method) to test the airtightness of oil-gas separators. This involves immersing the product in water or applying soapy water, applying pressure, and observing for bubbles to determine if there is a leak. However, this method has drawbacks: low sensitivity, only suitable for detecting large leaks; water or soapy water may seep into the product during testing, contaminating it; and bubble observation relies on human judgment, easily affected by operator experience, fatigue, and lighting conditions, resulting in poor efficiency and consistency. Utility Model Content

[0003] The purpose of this invention is to provide an airtightness testing device for oil-gas separators, which has a simple structure, a high degree of automation and good stability, and can effectively test the airtightness of oil-gas separators.

The vertical quick clamp is used to fix the oil-gas separator on the base. The oil-gas separator includes an oil return port, an air inlet connector, and an air outlet connector. An air inlet is provided on the outer side of the base, and an air passage is opened inside. The air inlet connector is connected to the oil return port through the air passage. The plug drive is used to drive the plug assembly to move closer to or away from the oil-gas separator to block or open the air inlet connector and the air outlet connector.

[0005] In use, the oil-gas separator is placed on the base and secured to it using vertical quick clamps, ensuring the oil return port is tightly against the air outlet.

[0017] like Figure 1-2 As shown, an oil-gas separator airtightness testing device includes a base 1, a vertical quick clamp 2, a plug assembly 9, and a plug drive 10. The vertical quick clamp 2 is used to fix the oil-gas separator 3 onto the base 1. The oil-gas separator 3 includes an oil return port, an air inlet connector 301, and an air outlet connector 302. An air inlet 101 is provided on the front side of the base 1, and an air passage 102 is provided inside. The output end of the air inlet 101 is connected to the oil return port through the air passage 102, and the input end of the air inlet 101 is connected to a three-way connector. The other two ports of the three-way connector are connected to the air inlet pipe and the air outlet pipe, respectively. The air inlet pipe is connected to an air source. The system is equipped with a connection, and the air outlet pipe is connected to the pressure sensor and the exhaust valve. The plug drive 10 is used to drive the plug assembly 9 to move closer to or away from the oil-gas separator 3 to block or open the air inlet 301 and the air outlet 302. The vertical quick clamp 2 is set on the base 1 and located on the left side of the oil-gas separator 3. The base 1 and the plug drive 10 are set on the workbench 4. The front side of the workbench 4 is equipped with a display screen 5, a start / stop button 1 6, a start / stop button 2 7 and an emergency stop button 8. The display screen 5 is electrically connected to the pressure sensor, the start / stop button 1 6 is electrically connected to the air source equipment, and the start / stop button 2 7 is electrically connected to the plug drive 10.

[0018] Specifically, the plug assembly 9 includes a first plug 901 and a second plug 902, which are respectively located on the same axial direction as the air inlet connector 301 and the air outlet connector 302. To improve the sealing effect of the plug, the first plug 901 and the second plug 902 are designed as cylindrical structures. The outer diameter of the first plug 901 is adapted to the inner diameter of the air inlet connector 301, and the outer diameter of the second plug 902 is adapted to the inner diameter of the air outlet connector 302. The first plug 901 and the second plug 902, made of rubber material, are elastic and can fit tightly to the interface to form a good seal, prevent leakage, and reduce vibration transmission during the sealing process, thus protecting the oil-gas separator 3. The plug drive component 10 includes a first cylinder 1001 and a second cylinder 1002. The first plug 901 is coaxially connected to the piston rod end of the first cylinder 1001, and the second plug 902 is coaxially connected to the piston rod end of the second cylinder 1002.

[0019] like Figure 3 As shown, a fixing groove 103 is provided on the base 1, and the oil-gas separator 3 is set in the fixing groove 103. An outwardly protruding elastic sealing gasket 11 is provided on the upper surface of the fixing groove 103 corresponding to the outer periphery of the air outlet of the air passage 102.

[0020] In use, the oil-gas separator 3 is placed in the fixed groove 103, and the vertical quick clamp 2 is used to press the oil-gas separator 3 onto the base 1. Press the start / stop button 7, and the piston rods of the first cylinder 1001 and the second cylinder 1002 extend, driving the first plug 901 and the second plug 902 to approach the oil-gas separator 3 until they respectively block the air inlet 301 and the air outlet 302. Press the start / stop button 6, and the gas source equipment works. Gas enters the oil-gas separator 3 through the air inlet pipe, the three-way connector, the air inlet 101, the air passage 102, and the oil return port. After pressurizing for a few seconds, press the start / stop button 6 again to shut off the gas source equipment. Continuously observe the pressure value on the display screen 5. If it is stable within the specified range, it is determined that the oil-gas separator 3 has no leakage. If the pressure value continues to drop, it is determined that the oil-gas separator 3 has a leakage. After the test is completed, open the exhaust valve. The advantages of this utility model are as follows: the oil-gas separator 3 can be quickly positioned by the fixing groove 103, avoiding leakage caused by position deviation and affecting the test results; when the vertical quick clamp 2 is used to fix the oil-gas separator 3, the sealing gasket 11 can automatically seal the gap between the oil return port and the gas outlet when it is pressed and rebounds, thereby preventing leakage from affecting the test results; this air tightness testing fixture has a simple structure, is easy to operate, saves layout space, and significantly improves the air tightness testing efficiency.
