What is the eccentric
wheel in the micro dc air pump for?
1. Connect the motor shaft and
connecting rod assembly: the eccentric is used to transmit the
rotational motion of the motor shaft to the connecting rod
assembly.
2. Control the vibration of the
connecting rod assembly: By driving the rotation of the eccentric
wheel by the motor, the connecting rod assembly can be driven to
vibrate.
3. Drive the diaphragm to reciprocate: the connecting rod assembly
is connected to the diaphragm, and the vibration of the eccentric
will cause the diaphragm to reciprocate.
4. Control the valve plate for the air inlet and outlet: The
reciprocating motion of the diaphragm cooperates with the valve
plate for the air inlet and outlet to complete the process of air
extraction and deflation.
Through the cooperation of the eccentric wheel and the connecting
rod assembly, the micro air pump can realize the function of
pumping fluid.
How does the eccentric in the small diaphragm air pump
control the vibration of the connecting rod assembly?
The eccentric wheel in the micro air pump controls the vibration of
the connecting rod assembly in the following ways:
1. Rotation of the eccentric: The rotation of the eccentric is
driven by the motor. When the motor shaft rotates, the eccentric
will also rotate.
2. Connection of the connecting rod assembly: One end of the
connecting rod assembly is connected to the eccentric, usually
through elastic elements such as sliding bearings or springs.
3. Vibration transmission: When the eccentric rotates, the
centrifugal force generated by it acts on the connecting rod
assembly, causing the connecting rod assembly to vibrate. Due to
the connection stiffness between the connecting rod assembly and
the eccentric, the vibration frequency and amplitude of the
connecting rod assembly will be limited.
4. Reciprocating motion of the diaphragm: The vibration of the
connecting rod assembly will cause the diaphragm to reciprocate at
the same frequency. The diaphragm is a closed elastic element whose
shape and size are designed according to the design requirements of
the small dc air pump.
5. Valve opening and closing: The reciprocating movement of the
diaphragm cooperates with the valve opening of the air inlet and
outlet to complete the process of pumping and deflating. When the
diaphragm moves toward the air inlet, the air inlet opens and air
is sucked into the pump; when the diaphragm moves toward the
exhaust port, the exhaust port opens and the air is discharged out
of the pump.
