Car Fuel Pipe Connectors How To Do Airtightness Test

Car fuel pipe connectors are a kind of airtight joints that can be quickly plugged in, connected, and disconnected and are mainly used for sealing and connecting, and ventilating when testing the tightness of fuel pipes. The following is an introduction to how car fuel pipe connectors are tested for tightness.

1. The basic principle of car fuel pipe connectors airtightness test

The role of the fuel pipe in the car is very important. To ensure the safe operation of the fuel supply system, it needs to be very strict in production and quality inspection. Strict inspection is required before leaving the factory, and leak detection are one of them.

The way to test the tightness of the fuel pipe is generally to use the method of ventilating leak detection. The principle is very simple: block all the outer nozzles of the fuel pipe, and then ventilate (or other test media) from one of the joints, ventilate to Certain pressure. Then plugging is carried out, and the change of air pressure inside the pipeline is observed within a certain period of time. Connect leak detector equipment or other methods, if the test result is within the specified range, it is qualified, otherwise, it is unqualified.

Here you need to use a quick connector to seal the nozzle of the fuel pipe and connect it to the air. The purpose of choosing quick connectors is to improve work efficiency and replace the previous method of hand-tightening nuts. The sealing connection has good stability, and the quick plug can be easily removed after the test is completed to continue the test of the next workpiece.
