I. Scope of Application
The pneumatic quick connector air tightness testing machine developed and manufactured by Jinan Siminte is used for the air tightness test of quick connectors.
It allows setting of holding pressure, pressure stabilization time, pressure holding time, and pressure drop value for air tightness and pressure testing of the tested products.
The power source of this testing machine is compressed air. The driving air pressure is proportional to the output pressure, and the corresponding boosted pressure can be obtained by adjusting the driving pressure.
When testing with the pneumatic quick connector air tightness testing machine, users must operate in accordance with the operating procedures to ensure a safe and reliable testing process.
At the same time, regular maintenance of the testing machine is very important to ensure its performance and accuracy.
 
II. Equipment Features
Equipped with a low-pressure air regulating valve, which adjusts pressure through a low-pressure proportional valve.
Advanced technology and reasonable structural design. The equipment features small size, light weight and elegant appearance.
Stepless pressure adjustment is available. Technical parameters such as pressure holding value and pressure holding time can be set.

It is suitable for the pressure and air tightness performance test of various valves, and used for the air tightness detection of various types of valves.
It is widely used in quality inspection institutions, auto parts manufacturers, product quality inspection stations, scientific research institutes and other fields involving the production, development and research of hoses.
The pressure test system consists of a pressurization system and a control & display system.
The system adopts Siminte gas booster pumps. The pressurization system is mainly composed of gas booster pumps, which is mainly responsible for system pressurization and pressure holding, ensuring long‑term test pressurization and pressure maintenance.
The control and display system mainly controls the pressure of driving gas, controls pressure relief, displays pressure in real time, and controls the pressurization process.
