[0002] In modern engine systems, the oil-gas separator is a key component, mainly used to separate gas from oil in lubricating oil to ensure the purity and lubrication effect of the lubricating oil, while reducing emissions. The working efficiency of the oil-gas separator is directly related to engine performance, fuel economy and environmental protection.

[0003] If there is a blockage or design defect inside the oil-gas separator, the airflow through it will be obstructed, resulting in abnormal pressure loss. This will not only affect its separation efficiency, but may also cause the lubricating oil to not circulate normally, thereby affecting the lubrication effect and operating stability of the engine. Therefore, pressure loss testing is required before leaving the factory to ensure that the product meets the design requirements and quality standards. Utility Model Content

The testing mechanism controls the input of the external air source. The placement seat is positioned above the testing platform 1 and is used to place the workpiece 2. The pressing mechanism includes a mounting bracket mounted on the testing platform 1. Mounting bracket 12, on which a pressing cylinder 13 is provided, the output shaft of which is connected to a pressure block 14 for abutting against the workpiece 2; the pressure acquisition mechanism is set on the placement seat and includes a first pressure sensor 35, a second pressure sensor 36 and a third pressure sensor 37, the first pressure sensor 35 is connected to the air pipe 11 of the air inlet 21 of the workpiece 2, the second pressure sensor 36 is connected to the air pipe 11 of the manifold 22 of the workpiece 2, and the third pressure sensor 37 is connected to the air pipe 11 of the air filter 23 of the workpiece 2.

[0021] By employing the above technical solution, workpiece 2 is positioned using a placement seat, and a pressing mechanism keeps workpiece 2 static, ensuring its stability during testing and avoiding measurement errors caused by external factors. An external air source supplies air to different ports of workpiece 2. The pressure changes at the air inlet 21, manifold port 22, and air filter port 23 are monitored by the first pressure sensor 35, the second pressure sensor 36, and the third pressure sensor 37, respectively. This allows for the calculation of the corresponding pressure differential values ​​required for testing, facilitating accurate evaluation of the oil-gas separator's performance, timely detection of potential blockages or design flaws, ensuring product quality, and providing data support for subsequent improvements. The overall system provides reliable assurance for quality control before shipment, ensuring the efficiency and reliability of the oil-gas separator while helping to reduce emissions and meet stringent environmental protection requirements.

[0023] As a preferred embodiment, the testing mechanism includes a pressure reducing valve 4, a solenoid valve 41, an air storage tank 42, and an air vent valve installed within the testing platform 1. The external air source is connected to the air storage tank 42 via the pressure reducing valve 4. The air vent valve includes an inlet air vent valve 43, a manifold air vent valve 44, and an air filter air vent valve 45. The inlet air vent valve 43 is connected between the air storage tank 42 and the air inlet 21 of the workpiece 2 via a pipe. The manifold air vent valve 44 is located at the end of the air pipe 11 at the manifold port 22, and the air filter air vent valve 45 is located at the end of the air pipe 11 at the air filter port 23.
