Pumping unit and ventilation device
2012
A pump unit (1) comprising: a plurality of micropumps (500) arranged in a grid with rows (m1-m5) and columns (n1-n5) design, transferring the micropump (500) a fluid in a direction along the columns (n); a discharge port integrated (50) which directly connects a discharge port (542) of at least one micropump (500) disposed in a bottom row (m1), receiving the port integrated discharge (50) fluid transferred by micropumps (500) to finally be discharged through the discharge port integrated (50); characterized by further comprising: a discharge mechanism of direct connection (70) is adapted to connect discharge ports (542) respective of the plurality of micropumps (500) in an intermediate row (m2-m5) directly to the discharge port integrated (50); a mechanism for admission of direct connection (80) adapted for connecting inlets (544) respective of the plurality of micropumps (500) in the middle row (m1-m4) directly to a port integrated intake (60); a connecting mechanism in series (90) that it is adapted to connect a discharge port (542) of micropump (500) in one row up (m2-m5) directly to an intake port (544) of a micropump ( 500) in one row down (m1-m4); and a controller (10) for controlling the discharge mechanism of direct connection (70), the admission mechanism direct connection (80), and the connecting mechanism in series (90), wherein the controller (10) adapted to control the serial connection mechanism (90) for connecting the discharge port (542) of micropump (500) in the row up (m2- m5) directly to the intake port (544) of micropump (500 ) in the row below (m1-m4) via the mechanism serial connection (90) to form a connection in a column direction (n1-n5), thus putting the plurality of micropumps (500) in a state pressure transfer preferred (Figure 5B), and for controlling the discharge mechanism of direct connection (70) for connecting the discharge ports (542) of micropump (500) in a plurality of rows (m1-m5) directly to integrated discharge orifice (50) through the discharge mechanism direct connection (70), and to control the admission mechanism direct connection (80) for connecting inlets (544) of micropumps in the plurality of rows (m1-m5) directly to port integrated intake opening (60) through the admission mechanism direct connection (80), thus putting the plurality of micropumps (500) in a state transfer preferred flow (Figure 5A).
