ATEQ is Available to Provide Consulting and Leak and Flow Testers For Automotive Shock Absorber Leak Testing Applications.
A shock absorber is an oil-filled cylinder with a piston inside of it used to dampen the excessive movement of the springs and suspension of a vehicle. They use valving of oil and gasses to absorb excess energy from the springs. Because these cylinders are filled with fluid, it is important that they are leak tested during the manufacturing process. A leaky shock absorber can be dangerous because if it is leaking hydraulic fluid, it will provide less viscous friction over time. This leads not only to an undesirable bumpy ride and costly wear on your tires, it also means that any bump, railroad track, speed bump or pothole could cause the car to fall off balance and cause an accident.
First, the main cylinder should be leak tested to make sure it will be able to contain the hydraulic fluid. This could be done by capping off one end an attaching it to an ATEQ differential pressure decay leak testers like the F620, along with a reference part to pressurize the test and reference parts with air and look for a pressure drop in the test part. Once the manufacturer is confident the main body cylinder of the shock absorber is airtight, it is important to test the welding of the the metal ring that intersects the body of the tube to ensure there are no welds that could cause leaks. To test the final assembly of the shock absorber, an indirect leak test method can be used. The process can be automated into a production line at a fast rate using a PLC by putting the shock absorbers in a custom test chamber fixture so look for a pressure rise in the chamber if there is a leak in the weld.
ATEQ has developed solutions for hundreds of different automotive leak testing applications for well known OEM manufacturers over the last 40 years. Whether you are leak testing shock absorbers, manifolds, full engines, EV battery packs, catheters, pacemakers, or a smartphone, ATEQ can work with you to provide efficient leak testers and develop integrated shock absorber production leak and flow testing solutions.
