The ampoule injection electronic microporous leak detector is mainly used for leak detection of ampoules, penicillin bottles, and oral liquid bottles. Including the detection of cracks in the micropores, seals, body, bottom, and other areas of the bottle.

The working principle of electronic microporous leak detection machine for ampoule injection:

The bottle feeding conveyor belt sends the container to be tested to the bottle feeding wheel for equidistant separation, and then the container is sent to the conveying screw for flipping through the bottle feeding torsion track. After being flipped 90 degrees, the container reaches different detection stations in a horizontal state. The detection is composed of multiple workstations, which can detect different positions according to user requirements. Finally, the qualified and unqualified products are automatically separated by the waste removal mechanism.

For high-frequency and high-voltage detection power supply, the two ends are connected to the emitter and receiver respectively. C1 and C2 are the capacitance values between the electrode and the solution (due to the partition of the insulating bottle wall, the electrode cannot come into contact with the solution, resulting in capacitance), and R is the resistance value of the solution. When the container does not leak, an induced microcurrent I1 is generated. When the container leaks, the capacitance between the bottle wall and the electrode disappears, and the capacitance generated by the capacitance is zero, resulting in a larger microcurrent I2 in the circuit. By comparing the magnitude of the microcurrent, it is determined whether the container is leaking.

The main advantages of electronic microporous leak detection machine for ampoule injection are:

1. High efficiency: It can be produced independently or linked with the production line, achieving automatic online inspection of each container being tested one by one;

2. High accuracy: It can detect ultrafine microcracks and micropores that cannot be detected by traditional methods, with high leak detection accuracy and high repeatability accuracy;

3. High safety: Due to the low energy and short time loaded on the tested container, qualified drugs pass through the testing area in an insulated state, and the detection voltage has no side effects on the liquid inside the drug, achieving non-destructive inspection of the container and drug;

4. Low pollution: There is no direct contact between the detection electrode and the drug, so there will be no pollution to the drug;

5. Strong universality: One device can adapt to the production of various specifications and containers by changing the mold. Containers such as ampoules, antibiotic bottles, oral liquid bottles, etc. can be produced on one device, improving the utilization rate of the equipment;

6. Advanced Control: A user-friendly touch screen interface with powerful functions such as control, display, data acquisition, and printing.
