AI Technical Summary
Technical Problem
The control solenoid valves of existing diaphragm pumps have complex flow channels and/or pipelines, and fluctuations in working gas pressure affect the stability and control accuracy of the diaphragm pumps.
Method used
An air passage chamber and an isolation chamber are provided inside the pump control housing, and connected to the control valve through the first and second housing channels. This simplifies the structure, stabilizes gas flow, buffers pressure fluctuations, protects the control valve, and ensures stable liquid intake and discharge of the diaphragm pump.
Benefits of technology
This achieves controllability and stability of the diaphragm pump's suction and discharge volumes, reduces flow fluctuations, and improves control stability and valve lifespan.
