Motor industry solutionsAs the global penetration rate of new energy vehicles exceeds 45% (2025 data), motors, as the core power component,Its sealing performance directly affects the safety and reliability of the vehicle.Leakage in the motor's internal cooling circuit may lead to coolant penetration, insulation performance degradation, efficiency loss, and even serious failures such as system short circuits.Hairis provides a complete sealing verification solution based on tracer gas detection technology for key components such as motor assembly, casing, cooling water channels and end covers to ensure that each drive motor meets the stringent sealing requirements of the electric vehicle industry.
Build a comprehensive testing system
Our solutions cover the entire manufacturing process from components to assembly:
Precision inspection of shell and end cover
For motor housings and end cover components, the requirements for leakage are low, and the Hairis air tightness detector can meet the needs and is suitable for rapid testing in large quantities.If the test accuracy exceeds air tightness and the leakage point needs to be accurately located, the Hairis HQ series hydrogen and nitrogen leak detector can be used with a specially designed testing tool to complete high-precision testing by filling the component with tracer gas (5% hydrogen + 95% nitrogen) at a specific pressure.This method accurately identifies micron-level casting defects and welding defects to ensure the sealing reliability of basic structural parts.
Cooling circuit integrity verification
During the motor assembly process, to detect the cooling circuit of the motor, different solutions can be selected according to different leakage rate requirements. If the leakage volume is required to be low, within 10^⁻4, the Hairis HC and HP series air tightness detectors can be used, which are low cost and suitable for rapid screening of large-scale production lines; if the accuracy exceeds the air tightness requirements，Then you can choose Heris hydrogen and nitrogen leak detectors and helium mass spectrometer leak detectors, which can accurately locate leak points, such as tiny cracks and welding defects.
Assembly final inspection solution
At the end of the motor assembly line,Deploy the Heris online helium mass spectrometry leak detection system, equipped with special docking tooling and automated transmission system, to achieve 100% online detection of the motor assembly.
