Engine field solutionsThe engine is the heart of a car, and its complex oil, water, and gas systems have almost stringent requirements for sealing.Small leaks not only lead to the loss of engine oil and coolant, causing performance degradation and excessive emissions, but are also potential threats to vehicle reliability, safety and brand reputation.
Hairis engine sealing testing solution is specially designed to meet this core challenge.Based on advanced tracer gas mass spectrometry analysis technology, we provide full-process, high-precision leakage detection from laboratory research and development to large-scale mass production for key components such as engine blocks, cylinder heads, oil pans, and intake manifolds.This program aims to help engine manufacturers build a solid quality defense line to ensure that every factory engine has a perfectly sealed "healthy heart".
Build a full-process, automated quality fortress
Our solution implementation covers all scenarios from offline sampling inspection to online full inspection, ensuring seamless connection between inspection and production rhythm.
Inspection preparation and workpiece processing:
According to the structure and testing requirements of engine components (such as cylinder block and cylinder head), special tooling fixtures and sealing plugs are designed and customized to achieve rapid and precise positioning and sealing.
At the appropriate interface of the engine assembly or component, connect the HiRes detection system and fill its sealed inner cavity with a safe tracer gas (such as helium or hydrogen-nitrogen mixture) of a specific pressure.
High-precision detection process:
The workpiece filled with tracer gas is sent into a closed detection chamber or scanned by a detection probe.
As the core of the system, Hairisi's high-sensitivity leak detector continuously monitors and analyzes trace trace gases escaping from potential leak points in the workpiece.
The system can accurately calculate the leakage rate of the workpiece within a few seconds to tens of seconds, with a resolution up to 10⁻¹¹ mb·L/s, far exceeding the accuracy of the traditional pressure decay method.
Data analysis and intelligent decision-making:
The test results (OK/NG) and specific leakage rate data are displayed on the HMI human-machine interface in real time.
All data are automatically uploaded to the MES/QMS system to generate detailed quality reports and statistical process control (SPC) charts to achieve complete quality traceability and process optimization guidance.
When you choose Harisi, you get not only an instrument, but also a value system that enhances your core competitiveness.
Quality jump: Detection accuracy with almost zero missed or misjudged results fundamentally eliminates leakage risks, significantly reduces the risk of market recalls, and safeguards brand reputation.
Cost control: Achieve rapid online full inspection, replace some inefficient and destructive water inspection methods, greatly improve inspection efficiency, and save spare parts and rework costs caused by misjudgment.
Efficiency improvement: The automated inspection process is seamlessly integrated into the high-speed production line, and the single inspection cycle can be controlled within the production cycle, effectively ensuring production efficiency.
Data-driven: Obtain quality data assets throughout the life cycle to provide scientific and quantitative decision-making basis for design improvement, process parameter optimization and supply chain management.
