Agricultural Diaphragm Pump (DAFENGDA): Features large flow rate, corrosion resistance and wear resistance. It can achieve rough proportional control by adjusting pressure/flow rate. Suitable for field irrigation and extensive fertilizer distribution.
A reliable selection process can refer to the following steps:
- Clarify Requirements: Determine the maximum injection flow rate, system working pressure, fertilizer type (liquid or dissolved solid), and control mode (manual/auto/intelligent linkage).
- Calculate Parameters:
- Required Flow Rate = Maximum Flow Rate of Irrigation System × Fertilizer Injection Ratio
- Required Pressure = Working Pressure of Irrigation System + Pipeline Loss + Safety Margin
- Match Products: Screen various diaphragm pumps according to the calculation results and budget.
- Confirm Details: Be sure to verify the pump material compatibility list, interface size, power supply requirements and signal protocol to see if they match the existing control system.
Important Notes
- Installation: It is recommended to install pressure switches and back pressure valves at the inlet and outlet of the pump, and install a filter at the front end to prevent fertilizer solution crystallization or impurities from damaging the pump valve.
- Maintenance: Regularly inspect and replace vulnerable parts such as diaphragm sheets and inlet and outlet water diaphragms according to the usage condition, which is the key to maintaining accuracy.
