DP-35 miniature electric diaphragm pump

Product Overview of the Type Micro Diaphragm Pump
The Type Micro Electric Diaphragm Pump produced by Yongjia Jicheng Pump Industry uses a micro DC motor (motor with a voltage of ) as the power drive device to drive the internal mechanical eccentric device for eccentricity Movement, the eccentric movement drives the internal diaphragm to reciprocate. Thereby, the air in the fixed volume pump chamber is compressed (the exhaust port is closed during compression, and the exhaust port is opened to form a slight positive pressure), and stretched (the exhaust port is closed during compression, and the exhaust port is opened to form a negative pressure at the pump exhaust port. There is a pressure difference with the outside atmospheric pressure. Under the action of the pressure difference, the gas is pressured (suctioned) into the pump chamber and then discharged from the exhaust port.

Working principle of miniature electric diaphragm pump
The first working mode of the micro diaphragm pump is the circular motion of the motor. The diaphragm inside the pump is reciprocated through a mechanical device, thereby compressing and stretching the air in the pump chamber to form a negative pressure, which is generated at the air suction port with the external atmospheric pressure. The pressure difference, under the action of the pressure difference, draws the gas into the pump chamber and then discharges it from the exhaust port.
Micro diaphragm pump The second working mode of the micro diaphragm pump uses the rotation of the screw to suck and discharge liquid. Micro diaphragm pump The middle screw of the diaphragm pump is the driving screw, and the screws on both sides are driven screws, which rotate in reverse direction with the driving screw. The threads of the main and driven screws are double-headed threads. Due to the mutual meshing of the screws and the contact between the screw and the inner wall of the liner, With a tight fit, the suction inlet and discharge port of the micro diaphragm pump will be separated into one or more sealed spaces. As the screw rotates and engages, these sealed spaces are continuously formed at the suction end of the pump, dividing the suction chamber into The liquid in it is sealed in it, and is continuously pushed from the suction chamber to the discharge end along the axial direction of the screw, and the liquid enclosed in each space is continuously discharged, just like a nut being continuously pushed forward when the thread rotates. This is The basic working principle of micro diaphragm pump.
