摘要
System with two pumps (B1, B2) connected in parallel to a delivery manifold and respective electronic pressure switches (P1, P2) provided with a pressure sensor (S1, S2) connected to the delivery manifold and designed to alternate their operation between a first configuration with a first shut-down pressure (Pmax1) and a first start-up pressure (Pmin1) and a second configuration with a second shut-down pressure (Pmax2) and a second start-up pressure (Pmin2), the first shut-down pressure (Pmax1) being greater than the second shut-down pressure (Pmax2) and the first start-up pressure (Pmin1) greater than the second start-up pressure (Pmin2). Each of the pressure switches (P1, P2) is designed to alternate their operation between the two configurations according to a pressure reading (Pimp) at the delivery manifold by the pressure sensor(s) (S1, S2). The invention also relates to a pressure switch.
