Dalian Leak Testing Machine for Automotive Parts: Suitable for Engine/Fuel Tank, Exclusive Sealing Testing Solution
In the quality control process of automobile manufacturing, the sealing of the engine and fuel tank is directly related to driving safety and performance stability. Traditional testing methods are susceptible to human factors and have difficulty ensuring accuracy. However, automotive parts leak testing machines have developed customized testing solutions based on the characteristics of these two core components, becoming the "core defense line" for car companies to maintain sealing quality.
As the "heart" of a car, the engine has strict sealing requirements for its multi chamber structure such as cylinder block, oil passage, and air duct. Even small leaks can lead to problems such as oil leakage and power loss. The leak testing machine adopts multi-channel synchronous detection technology for the complex structure of the engine. It precisely connects with each cavity through customized sealed joints and uses negative pressure or differential pressure methods to achieve simultaneous detection of multiple parts. During detection, the device draws the engine chamber to the set pressure and monitors pressure changes in real time through sensors. Even small fluctuations of 0.1 Pa can be accurately captured and the leakage point can be quickly located. For engines of different displacements and models, the equipment can switch detection parameters with one click, with strong adaptability and a 60% increase in detection efficiency compared to traditional methods.

As the core component of fuel storage, the fuel tank of Dalian leak testing machine not only needs to withstand high-pressure impact, but also needs to eliminate safety hazards caused by fuel evaporation and leakage. The leak testing machine has customized specialized fixtures for fuel tank testing, and designed a fitting sealing module based on the irregular structure of the fuel tank to ensure airtightness during testing. When using the positive pressure detection principle, the equipment fills the inside of the fuel tank with dry nitrogen gas to the rated pressure, maintains a stable state, and monitors the gas leakage through a high-precision flowmeter. The lower limit of leakage rate detection can reach 0.01ml/min, far exceeding industry standards. For fuel tanks made of different materials such as plastic and metal, the equipment can automatically adjust the pressure parameters and detection time, avoiding damage to components caused by excessive pressure while ensuring detection accuracy, perfectly adapting to diverse needs.
The core advantage of exclusive solutions is reflected in the intelligence and dataization of the entire process. The industrial control system equipped with the leak testing machine can store thousands of detection parameter templates for engines and fuel tanks, and there is no need for repeated debugging when changing models; Real time upload of detection data to MES system, automatic generation of detection reports, and implementation of quality traceability. After a certain car company introduced this solution, the engine leakage failure rate decreased from 1.2% to 0.3%, and the fuel tank inspection pass rate increased to 99.8%, significantly reducing after-sales risks and rework costs.
The Dalian leak testing machine accurately detects the multi chamber of the engine and adapts to the irregular structure of the fuel tank. The automotive parts leak testing machine solves the sealing detection problem of core components with customized solutions. It is not a simple modification of general equipment, but a deep research and development based on component characteristics, providing reliable guarantees for the sealing quality of automotive manufacturing with professional adaptability and precise detection capabilities.
