Product Description Application JLYZ Syringe Electronic Micropore Leak Detector is mainly used for the sealing integrity testing of containers such as pre-filled syringes, plastic syringes and the coverage testing of the bottle body and bottle tail.Working PrincipleJLYZ Syringe Electronic Micropore Leak Detector adopts high-voltage discharge detection technology, the actual proof of the industry and the use effect of customers, the high-voltage discharge detection method has higher detection accuracy and faster detection speed than the color water method, and the high-voltage discharge the detection technology is currently recommended by FDA and EU GMP. Detecting principleThe detection principle is shown in the following figure:In Figure: V high-frequency high-voltage power supply, C1: capacitance between emitter and liquid; C2: capacitance between receiver and liquid; R: resistance of liquid. V is the high-frequency high-voltage detection power supply, the two ends are connected to the emitter and the receiver, respectively, C1 and C2 are the capacitance values between the electrodes and the capacitors (due to the partition of the bottle wall, the electrodes cannot be in contact with the liquid, so the capacitance is generated), R is the resistance value of the liquid medicine. When the ampoule bottle does not leak, an induced microcurrent I1 is generated. When the bottle leaks, the capacitance between the insulating bottle wall and the electrode disappears, the capacitive reactance generated by the capacitance is zero, and the circuit generates a relatively small amount of capacitance. Large microcurrent I2. As long as the size of the microcurrent is compared, it can be judged whether the bottle is leaking.Reasons why capacitance exists and disappears: According to the definition of capacitance, there is capacitance between two conductors that are insulated from each other and spaced very close together. Among the equipment, the emitter is a metal product, which is a conductor; the liquid medicine is also a conductor, and the two are separated by an insulating container wall; therefore, there is a capacitance. When there are cracks and micropores in the container wall, the high-voltage electricity will break down the container wall, the emitter and the liquid medicine will form a path, and the capacitor C1 will disappear.The basis for judging waste products: the device collects the current value of each drug at high speed (the speed is extremely fast, and the interval between each acquisition is at the ms level), and then compares the maximum value of the current value of each drug with the set upper limit, if it is greater than or equal to the set upper limit , the system judges it as a waste product, otherwise it is a qualified product. Technical parameters:Main application: It is used to detect defects such as cylinder body and cracks emerging from the tip.Scope of application: 0.5~20mL SyringesDetection accuracy: 0.1umDetection station: 2Adjustable range of high voltage power : 0~30KVDetection speed: 4000X (1±10%) PCS / min.Electric capacity: 3.5kW, 380(1±5%)V, three-phase AC, 50 Hz.Workbench height: 900mm.Device size (frame): 1500x850x1650 (length X width X height) AdvantagesIt can be linked with the production line to automatically inspect the inspected containers one by one onlineIt can detect ultra-fine cracks and pores that cannot be detected by traditional methodsDue to the low energy and short time loaded on the container to be inspected, qualified drugs are in an insulated state when they pass through the detection area. And the detection voltage has no bad effects on the inner liquid of the drug which realize non-destructive inspection of the container and the drugThere is no direct contact between the detection electrode and the medicine, and it will not pollute the medicine.A piece of equipment can be adapted to the production of containers of various specifications by changing specifications, and changing specifications is quick and convenientHuman-machine friendly touch screen with powerful functions such as control, display, data collection and printingProvide a full set of verification standards that meet GMP requirementsAt present, the leak detection series products have obtained a number of patents and rich technical support
