Pneumatic diaphragm troubleshooting methods

The Shanghai allmarine wilden pump Laboratory analysis of pneumatic diaphragm pumps troubleshooting steps.

A. Before the demolition of the pneumatic diaphragm pump chamber and liquid chamber in the left and right, respectively, marked with a mark to contribute to the subsequent re-assembly action.

Two. Use a wrench to loosen the small clamp to connect the outlet pipe and the liquid chamber, remove the outlet tube to see the ball and seat, took out the ball and seat and check the pump spare parts for wear, chemical corrosion, cracks and other phenomena.

3. Use a wrench to connect the inlet tube and the liquid chamber, a small clamp to loosen and remove the outlet tube to see the ball and seat, to come up with the ball and seat and check the pump spare parts for wear, chemical corrosion, cracks and other phenomena.

4. Use the wrench to separate the intermediate fluid chamber and pump to remove the liquid chamber to see the diaphragm and the diaphragm plywood.

5.The use of tools or wrench diaphragm outside the plywood around the edge of the diaphragm device with intermediate separately. Clockwise rotation then release the diaphragm device. Out of the patch outside the plywood, the shaft removed from the intermediate.

6. Clamp (padded wood) shaft separated from the diaphragm device, check the shaft, plywood, and the diaphragm for damage and corrosion phenomena.
