working principle:

Taking a single tank as an example, the natural pressure of the high-level feeding bin 1 is used to press the slurry into the interior of the diaphragm 5 in the diaphragm tank 6 through the inlet check valve 8. At the same time, the return water clear water valve 2 is in the open state and the inlet water clear water valve 3 is in the closed state. The clean water outside the diaphragm returns to the circulating water tank 10 through the return water valve 2, completing the slurry inlet process; After the slurry inlet is completed, close the return water clean water valve 2 and open the inlet clean water valve 3. High pressure clean water is provided by the multi-stage clean water pump 9 and enters the interlayer between the diaphragm tank 6 and the diaphragm 5 through the inlet clean water valve 3. The diaphragm is compressed and deformed, and the slurry inside the diaphragm is discharged to the discharge pipeline through the discharge check valve 7. Three diaphragm tanks alternate suction and discharge of slurry, with a phase angle difference of 120 ° in operation. Achieve the goal of continuous slurry discharge.

The movement state of the diaphragm is achieved by a detection device installed on the isolation tank, and the adjustment of flow matching and flow fluctuations is achieved through data acquisition from displacement sensors in the silo and water tank, controlled by a microcomputer through frequency conversion. Fault detection is carried out by the clear water valve, and its faults are judged and processed by the microcomputer.

Intelligent diaphragm pump is a highly intelligent device, with all work operations randomly adjusted and fault diagnosis and emergency handling implemented by a microcomputer.
