What are the applications of air tightness testers in the automotive manufacturing industry?   Power system Engine: Detect the air tightness of key components such as cylinders, pistons, and valves to discover and repair manufacturing defects, prevent and diagnose faults, and ensure the power output and fuel efficiency of the engine.     Automobile motor: As the core component of the automotive power system, air tightness testing can ensure the sealing performance of the motor, prevent safety accidents caused by motor leakage, and improve the overall quality of the automotive motor. Fuel system: It can quickly detect tiny leaks in the fuel system, repair them in time, ensure the sealing of the fuel system, avoid fuel waste and reduce safety risks such as fire. Braking system: Strictly test the master brake cylinder, slave cylinder, and brake pipeline to ensure that the braking system can work stably and reliably under various working conditions, avoid weakening or even failure of the braking effect, and ensure driving safety. Air conditioning system: It can quickly and accurately detect the leakage location of the air conditioning system, perform repairs and sealing in time, prevent refrigerant loss, improve the performance and service life of the air conditioning system, and ensure driving comfort. Cooling system: Effectively detect the sealing of components such as radiators, water pumps, and water pipes in the cooling system to ensure normal heat dissipation of the engine and prevent coolant leakage from causing engine overheating. Power battery: In new energy vehicles, detect the sealing performance of the battery, improve the safety and reliability of the battery, promote the improvement of production efficiency and the optimization of quality control.     Wheel Accurately detect whether there is a leakage problem in the wheel hub, ensure the quality of the wheel hub, ensure the stability of the internal air pressure of the tire, improve the adhesion between the tire and the ground, make the vehicle more stable and more maneuverable, and reduce the rolling resistance of the tire and reduce the fuel consumption of the vehicle. Other parts Such as gearboxes, cameras, motors, wiring harnesses, die castings, headlights, water tanks, fuel tanks, controllers, shock absorbers, nozzles, radiators and other key components for air tightness testing to ensure the safety and stable operation of the car.
