car fuel tank capInspection is an important link in the production and manufacturing process of fuel tank caps.Before the car fuel tank cap is ready to leave the factory, it will undergo a waterproof test to check the quality of the product.The long hours of operation and quality inspection personnel, coupled with the influence of other factors, make it difficult to effectively guarantee the waterproofing effect of automobile fuel tank caps.

Product to be tested: car fuel tank cap

The traditional detection method of soaking in water is mainly performed by the operator's eyes. This method is inefficient, prone to misjudgment, and takes a long time.Hiraysi automobile fuel tank cap special testing instrumentUse compressed air to test the air tightness of the product. The parts that need to be tested this time are:Whether the entire fuel tank cap and the connection between the fuel inlet and the edge are completely sealed.

In order to keep up with the production capacity and combine the needs of customers, Hirays customized a dual-channelfuel tank capAir tightness testingequipment.It can not only increase production but also save costs, and can independently start independent judgments.Not affected by the other party’s test results, very cost-effective.

Car fuel tank cap air tightness testing

The following is an introduction to the testing process of the dedicated testing instrument used by Hirays fuel tank caps:

The parts that need to be tested this time areWhether the entire fuel tank cap and the connection between the fuel inlet and the edge are completely sealed。

For leakage detection of the fuel tank cap, the fuel leakage rate of the fuel tank cap should first be detected. When the pressure is7500Paconditions should not exceed60mL/min.The pressure loss test has a1LThe space between the left and right, the initial pressure is7000Pa, in the next10seconds, the pressure loss should not exceed1500Pa。

Fuel tank caps are specially designed for testing instruments

Testers need to pay attention to the following points when using the instrument.Before starting the test every day, we need to reset the test instrument to zero, then block our hose to check whether the inlet pressure of the instrument is what we need.43KPA，If the intake pressure changes, the pressure regulating valve needs to be adjusted to achieve the required pressure value.Before proceeding with pipeline testing, we need to test aOK Taste oneNGIf there is no abnormal reaction of the test instrument before testing other products.

Since its establishment, Hiraysi has been“Revitalize national industry”For the mission, focus on the fields of production automation and inspection automation;Actively explore, conduct in-depth research, and boldly innovate.We use our professional knowledge and rich practical experience to provide customers with high-efficiency, high-quality, and high-reliability products and services.
