what is the difference between solenoid pump and diaphragm pump?

1. Working principle: The working principle of AC Solenoid Pump is to use the principle of electromagnetic induction to drive the motor of the water pump through alternating current, thereby driving the water pump to work. The DC Diaphragm Water Pump uses direct current to drive the motor, which rotates to drive the water pump to work.

2. Pump body structure: The pump body structure of AC electromagnetic water pump is relatively simple, mainly composed of electromagnetic coil, rotor, stator, and pump casing. The pump body structure of DC Water Pump is relatively complex, mainly composed of motor, diaphragm, pump casing, and controller.

3. Flow regulation: Micro DC diaphragm water pumps can usually adjust the flow by changing the motor speed or pulse frequency, thereby achieving better flow control. The flow regulation of micro AC electromagnetic water pumps is relatively simple, usually achieved by adjusting the size of the water inlet.

4. Control method: The flow and pressure of the micro electromagnetic pump can be achieved by adjusting the voltage and frequency of the power supply, while the Micro diaphragm pump needs to adjust the flow and pressure by controlling the air source pressure.
