UAVs are engaged in outdoor monitoring, sample sampling, film and television shooting, etc. Due to the complex working environment, the performance requirements of the drone itself are relatively high and the service life is extended to avoid damage to the drone in harsh operating environments.Among them, sealing is its standard function, and sealing testing has become an indispensable link in production.Therefore, after the drone was launched on the market, Hirays Technology's drone sealing tester was officially launched and put into use for drone production testing.

This UAV sealing tester uses compressed air as the testing medium, and the pressure drop test method is used for sealing testing.By introducing a certain pressure and a certain volume of gas into the sealed workpiece cavity, then cutting off the compressed air supply to the component (closing the valve), allowing the pressure to stabilize for a period of time, and then measuring the pressure change after a predetermined measurement time.If a leak is present, the sensing pressure will drop.This method has the advantages of good executability, easier identification of sealing properties, no damage to contaminated workpieces, and easy automation of the test process.Its principle and detection method are shown in the figure below:

Hirays Technology UAV sealing detector can support leakage testing methods such as leakage testing, obstruction testing, positive pressure testing, and negative pressure testing. Because drones of different application categories have different detection needs, the leakage test range of this detector is -80kpa~1000kpa. Within this range, users can choose according to their own needs. It is also equipped with a product detection alarm function, which can eliminate detection errors caused by manual misjudgment and misdetection.The following are the relevant parameters of the detector:

In terms of realizing automatic detection of drone sealing, Hirays Technology has equipped it with"positive, negative&"Two pressure forms and 8 basic test modes, which can be selected individually or combined.It uses 24-bit A/D conversion, 32-bit CPU operation, and a completely independently developed industrial control operating system, combined with a full-touch human-computer interaction interface.Built-in RS232 serial port, RJ45 network port, USB communication interface, LTP external I/O control port, supports multiple communication protocols, enhances the operability of the equipment and improves the efficiency of the manufacturer's detection.

The above content is a detailed explanation of the operating principle of the Hirays UAV sealing tester. This tester has been widely used in civil and commercial UAV sealing testing.
