Abstract
1. Циркуляционный насос центробежного типа, имеющий по меньшей мере одно рабочее колесо (32), кожух насоса и один электрический двигатель, причем насос имеет кривую насоса «напор-расход» (4), имеющую напор H(28) при нулевом расходе и напор H(30), соответствующий наибольшей гидравлической мощности, отличающийся тем, что H(30) больше, чем H(28).2. Циркуляционный насос по п.1, отличающийся тем, что по меньшей мере одно рабочее колесо (32) содержит лопасти рабочего колеса (34), которым придана такая форма, при которой H(30) больше, чем H(28).3. Циркуляционный насос по п.1 или 2, отличающийся тем, что первая часть (8) кривой «напор-расход» имеет возрастающую функцию относительно расхода (6).4. Циркуляционный насос по п.1, отличающийся тем, что последняя часть (10) кривой «напор-расход» (4) имеет понижающую функцию относительно расхода (6).5. Циркуляционный насос по п.1, отличающийся тем, что кожух насоса и/или рабочее колесо (32) приспособлены для размещения средств ограничения расхода, так что конечная часть кривой «напор-расход» (4) имеет понижающую функцию относительно расхода (6).6.

Циркуляционный насос по п.1, отличающийся тем, что двигатель является двигателем с постоянным магнитом с пуском от сети.10. Циркуляционный насос по п.1, отличающийся тем, что лопасти рабочего колеса (34) изогнуты дугой и симметрично располагаются вдоль периферии1. A centrifugal type circulation pump having at least one impeller (32), a pump casing and one electric motor, the pump having a head-flow curve (4) having a head H(28) at zero flow and a head H(30) corresponding to the highest hydraulic power, characterized in that H(30) is greater than H(28).2. Circulation pump according to claim 1, characterized in that at least one impeller (32) comprises impeller blades (34) shaped such that H(30) is greater than H(28). Circulation pump according to claim 1 or 2, characterized in that the first part (8) of the pressure-flow curve has an increasing function with respect to the flow (6). Circulation pump according to claim 1, characterized in that the last part (10) of the pressure-flow curve (4) has a decreasing function relative to the flow (6). Circulation pump according to claim 1, characterized in that the pump casing and/or the impeller (32) are adapted to accommodate flow limiting means, so that the end part of the head-flow curve (4) has a decreasing function relative to the flow (6). 6. Circulation pump according to claim 1, characterized in that the impeller (32) has saber-shaped blades (34). The circulation pump according to claim 1, characterized in that the motor is a synchronous motor. The circulation pump according to claim 1, characterized in that the centrifugal pump is a sealed (capable of working with lubricant) pump. The circulation pump according to claim 1, characterized in that the motor is a mains-started permanent magnet motor. The circulation pump according to claim 1, characterized in that the blades of the impeller (34) are curved in an arc and are symmetrically located along the periphery
