Dry vacuum pumps (oil-free vacuum pumps) are widely used in leak
detection applications that demand high cleanliness, corrosion
resistance, and operational efficiency due to their oil-free
operation, corrosion resistance, and simple maintenance
requirements. The following outlines typical industries and
components where dry pumps are essential for leak testing:
1. Semiconductor and Electronics Industry
- Leak testing components:
- Wafer fabrication equipment (e.g., etching machines, CVD reaction
chambers)
- High-vacuum sealed devices (MEMS sensors, chip packaging)
Vacuum coating equipment
2. New Energy Industry (Lithium Batteries/Hydrogen Energy)
- Leak testing components:
- Lithium battery electrolyte filling chambers
- Fuel cell bipolar plates/stack sealing
- Hydrogen storage tank valves and pipelines
3. Medical and Pharmaceutical Industry
- Leak testing components:
- Sterile packaging (vials, prefilled syringes)
- Vacuum freeze dryers (lyophilizers)
- Medical catheters/implant device packaging
4. Automotive Industry
- Leak testing components:
- New energy vehicle battery pack sealing
- High-pressure fuel system pipelines (for hydrogen fuel cell
vehicles)
5. Scientific Research and High-End Manufacturing
- Leak testing components:
- Particle accelerator vacuum pipelines
- Spacecraft fuel tanks (satellites, rockets)
- Superconducting equipment cooling systems
