Operation of electromagnetic water pump system

The operation of Solenoidcoil pumping systems

The initial state (non-energized)

1 is set to the left end of the iron core of the vacuum chamber 1, which is the volume V1, the pressure Pl.

2 is set to the right end of the vacuum chamber 2 cores, its volume V2, pressure is P2.

3. Set the outside air pressure is P.

4. In the initial state is not energized, the spring is fixed to the iron core leftmost pump? Air pressure inside the vacuum chamber P1 = P2 = P (strong consistent with the external atmospheric pressure), the vacuum chamber is at a minimum volume V1 1 .

Pressure: is the pressure per unit area, in a sealed container, the air inside the container or fluid pressure in the unit of surface area is the pressure when the volume increases or decreases, the pressure will be smaller or inverse relationship becomes large.

Common pressure units Bar, 1Bar = 0.1M Pa = 14.5Psi = 0.98kg / cm²;

1 atm = 101.325KPa = 10.336 m water column;

Start energized

When energized, the electromagnetic field, the core moves to the right, the volume inside the pump chamber 1 V1 becomes large, that is, its pressure P1 becomes smaller, the volume inside the pump chamber 2 V2 becomes smaller, that is, it increases the pressure P2 In this case P1

Continuing rightward movement of the core, the vacuum chamber 1 becomes the minimum pressure Pl, the vacuum chamber pressure P2 becomes a maximum of two, one-way valve B is opened, the air from the vacuum chamber 2 to the vacuum chamber 1, and the equilibrium P2 = P1.

Just off state (truncated half-wave diode)

The electromagnetic force disappears, the rebound force generated by the compression spring will push the core movement to the left, resulting in the volume V1 of the vacuum chamber 1 becomes smaller, larger pressure P1 (P1> P) A one-way valve is opened, air from the vacuum chamber 1 to the outside.

When the power is continuously on / off, repeat the above steps, when the air in the pump body 2 of the vacuum chamber is completely left to form a row of negative pressure vacuum, atmospheric pressure outside the body strong through the pump pressure, the atmospheric pressure in the presence of water entering the pump, which pumps a steady stream being pumped from the right to the left.
