LPJL80 series plastic ampoule electronic microporous leak detector

Mainly engaged in the research and development of ceramic new material valves, with metal valves (gate valves, globe valves, ball valves, butterfly valves) as a secondary business. Ceramic valves have been successfully applied in many new energy battery material plants, thermal power plants, nuclear power plants, chemical plants, steel plants, coal chemical industry, polysilicon and other industries, and have been listed as special-purpose products, contributing to energy conservation and environmental protection for enterprises and society.

Main Use

This equipment comprehensively detects leaks in rows of plastic ampoules produced by a three-in-one blow-fill-seal production line. It can also detect similar packaged products such as rows of eye drops and rows of oral liquids.

Working Principle

Rows of plastic ampoules are manually or automatically fed onto the infeed conveyor belt. The accelerated conveyor belt separates and sends the ampoules to the inspection station. The conveying device transports the rows of plastic ampoules towards the inspection channel, passing through channels 1 and 2 in sequence. Channels 1 and 2 inspect the body, head, and tail of the rows of plastic ampoules. Then, through a turning wheel mechanism, they are transported to channels 3 and 4 in sequence. Channels 3 and 4 inspect the head, tail, and body of the other side of the rows of plastic ampoules. Finally, the reject mechanism separates the qualified and unqualified products. Qualified products are transported to the subsequent workstations via the qualified product conveyor belt, while unqualified products are collected in a waste bin (the waste bin is provided by the user and is not shown in Figure 1).

Detection Principle

The detection principle is shown in Figure 2-1. In the figure, V is a high-frequency high-voltage power supply, with its two ends connected to the emitter and receiver respectively. C1 and C2 are the capacitances between the emitter and receiver and the solution (due to the container wall separating the solution and the electrodes, there is no direct contact, hence the capacitance). R is the resistance of the solution.

When the row of plastic ampoules is not leaking, the simplified circuit of the entire loop is shown in Figure 2-2. In this case, the circuit will generate a microcurrent I1.

When the row of plastic ampoules leaks, the electrode and the solution will be directly connected, and the capacitance generated by the container wall will disappear. The simplified circuit of the entire loop is shown in Figure 2-3. In this case, the circuit will generate a current I2.

By comparing the magnitudes of I1 and I2, it is possible to determine whether the row of plastic ampoules has a leak.
