The diaphragm pump equipment system is composed of one or more bilateral pumps, such as a pneumatic double diaphragm pump. The manifold on the pump is separated, so that one component of the multi-component material is pumped from each side of the pump, and an accumulator is connected with the output on both sides, so that the out of phase output of the pump becomes in phase. Diaphragm isolation valves can be selected at the outlet of each side of the pump to prevent backflow of mixed materials. If a mixing ratio other than 1:1 is required, more than one such pump can be used together to achieve multiple mixing ratios.

Diaphragm failure monitoring system is used to detect the leakage of diaphragm of diaphragm pump. The system comprises a pump, which is provided with a working chamber and is filled with working fluid; A pumping chamber for pumping materials into and out of the pump; And a diaphragm to isolate the working chamber from the pumping chamber. A first optical fiber is connected with the working chamber to transmit an optical signal through the working fluid. A second optical fiber is connected with the working chamber to receive the optical signal transmitted from the first optical fiber. An electrical signal establishing device establishes the first electrical signal when the optical signal is transmitted from the first optical fiber and passes through the uncontaminated working solution to the second optical fiber. The electric signal establishing device establishes a second electric signal when the optical signal is transmitted from the first optical fiber and passes through the polluted working solution to the second optical fiber. When the second electrical signal is established, according to this, leakage of contaminated material through the diaphragm into the chamber can be detected.

The internal diaphragm installation method of diaphragm pump is carried out on the geometric dimensions of the diaphragm without affecting the volume change requirements of the pump and taking full advantage of the excellent compression resistance of the diaphragm. It can greatly improve the service life of the diaphragm without increasing any cost and workload, ensure the normalization of production and improve the production quality. It can be applied to the installation of internal diaphragms of various diaphragm pumps.
