Vacuum Helium Leak Detection System for New Energy Vehicle Air Conditioners: A Comprehensive Solution

Product Introduction

This system is a crucial part of the production process for new energy vehicle air conditioners. It is designed to accurately detect leaks in automotive air conditioning compressors, thereby guaranteeing product quality and performance. The system operates based on the principle of using helium as a tracer gas. Thanks to its advanced technology and reliable components, it can efficiently and accurately identify even the smallest leaks, ensuring the reliability and durability of air conditioning compressors.

Technical Parameters

System Function

Automated Leak Detection Process: Once the operator loads the workpiece into the vacuum chamber and closes the door, the system takes over. It automatically conducts a series of operations, including gross leak and strength tests, vacuuming, helium filling, fine leak detection, and helium recovery. This fully automated process not only improves production efficiency but also reduces the chance of human error, ensuring consistent and accurate test results.

High - Precision Leak Detection: With a sensitivity of up to 2g/y in helium leak detection, the system can accurately identify the slightest leaks in the air conditioning compressor. This high - precision detection ability helps to maintain the quality of the final product, preventing potential problems such as refrigerant leakage, which could affect the performance and lifespan of the air conditioner.

Efficient Helium Recovery: The system has an impressive helium recovery rate of ≥98%. This not only reduces the cost of using helium but also helps to protect the environment by minimizing gas waste.

Core Component Quality Assurance

Vacuum Chamber Unit: The vacuum chamber is made of high - quality stainless steel. Its vertical - opening door structure is equipped with a grating protection system, ensuring safety during the closing process. Additionally, 4 sets of fixtures are provided, making it convenient to install and test workpieces.

Vacuum and Leak Detection Unit: Key components such as the vacuum pump (BAOSI brand), vacuum gauge (AGILENT brand), and helium mass spectrometer (AGILENT brand) are used. These imported - brand components ensure high - precision vacuum generation and leak detection, enhancing the overall performance and reliability of the system.

Electrical Control Unit: Controlled by a PLC and with a 10 - inch color touch screen for easy operation and monitoring, the electrical components from well - known brands like FUJI and Schneider ensure system stability and durability.

Helium Concentration Monitoring and Automatic Refill Function: The system is equipped with a helium concentration meter. When the helium concentration drops below the set value, it can issue an audible and visual alarm and automatically refill helium, ensuring the normal operation of the leak detection process.

Calibration and Accuracy Assurance

The equipment is equipped with a 2.0 - gram/year helium standard leak hole, which has a calibration certificate issued by the National Institute of Metrology, China. This ensures the traceability of the equipment's accuracy and stability to a national - level metrology institution, guaranteeing third - party recognition of the leak hole. Regular online checks using a standard leak hole for daily inspection can maintain the system's accuracy and reliability.

Safety Assurance

Pressure Safety: The high - pressure containers used have valid certificates and are equipped with over - pressure safety valves and sensor over - pressure alarms to prevent potential pressure - related accidents.

Electrical Safety: All electrical components meet safety standards. The equipment is properly grounded and equipped with leakage protection devices to ensure operator safety.

Motor Safety: Motors are protected against current overload, extending their service life and ensuring stable operation.

On - site Safety: Emergency stop switches are installed at the operation area and maintenance points. The equipment is surrounded by a protective net, and there are clear safety operation instructions, maintenance guidelines, and safety training programs available.

Installation Conditions

Power Supply: A 380V - 3 - phase 5 - wire power supply at 50HZ with a power consumption of 10KW is required. The power supply should be connected to the terminal in the electrical cabinet by the customer.

Gases: Industrial helium (purity 99%, source within 2 meters of the equipment inlet, inlet pressure 0.1MPa with a customer - provided pressure reducer), industrial nitrogen (purity 99%, source within 2 meters of the equipment inlet, inlet pressure 3.0MPa with a customer - provided pressure reducer), pure nitrogen (purity 99.9%, source within 2 meters of the equipment inlet, inlet pressure 0.2MPa with a customer - provided pressure reducer), and clean and dry compressed air (pressure 0.5 - 0.7MPa) are needed for different purposes in the leak detection process.

Environment Temperature: The equipment should be installed in an environment with a temperature range of 5 - 40℃.
