BFDJ series diaphragm rupture alarm device sends a signal and shuts down the diaphragm pump as soon as the diaphragm ruptures, which can minimize the possibility of material leakage and eliminate the fault in the first time to ensure production.

Working Principle: The diaphragm pump equipped with a diaphragm rupture alam has two sets of diaphragms, namely the first diaphragm and the second diaphragm. The first diaphragm is in direct contact with the medium, and a closed cavity is fommed between the second diaphragm and the first diaphragm. During the working process, when the first diaphragm ruptures, the medium will enter the closed cavity 2. At the same time, the medium wil pass through the right-angle ferrule fittings, stainless steel pipe, Tee ferrule fittings, and finally flow out from the middle outlet of Tee ferule fittings. After the medium enters the medium induction cartridge, the sensor in the induction cartridge will send out a signal. which can be connected to control elements such as PLC to realize signal feedback. The user can perform the necessary logical operation processing according to the signal to realize the early waming, and ensure that the user is aware of the early warning information that the diaphragm of the diaphragm pump has ruptured. in addition, the sensor output signal can also realize the functions of sound and light alam, automatic shut down of the pump and other functions.
