pumps
Instrukcja obsługi pompowni wyposażonej w pompę rozdrabniającą. Zastanawia mnie ten przedrostek "semi".
Environment One’s semi-positive displacement, progressing cavity pumps provide predictable flow over a wide variety of pressures.
Czy to będzie po prostu pompa wyporowa?

pompa wyporowa o wydajności niezależnej od ciśnienia pracy
Based on the definition:
Basic Characteristics of SPD Grinder Pumps
The signifi cance of a semi-positive displacement (SPD) pump is not immediately apparent except to those experienced and skilled in the art of pump design and application. The SPD characteristic means that the flow (Q) from the pump is very nearly constant, no matter what the back pressure (H). In practical terms, in a pressure sewer system, it means that when a pump is turned “on,” it will deliver a useful amount of fl ow into the system, no matter where it happens to be within its allowable range of operating pressure. The flow volume will be, for all practical purposes, independent of pressure in the system. The maximum pressure may temporarily exceed the steady state normal rating by up to 50 percent with no harm to the pump or piping.

ccccccccccccccccccccccccccccccccc
W teoretycznych (idealnych) warunkach wydajność pompy (przy stałych obrotach) powinna być niezależna od ciśnienia pracy.

pompa wyporowa oparta na zasadzie Moineau
Działanie pompy wyporowej jest oparte na zasadzie Moineau. Rotor obraca się wewnątrz statora, wytwarzając szereg zamkniętych, przesuwających się komór. Rotor, wykonany z dużą precyzją jako polerowany odlew ze stali nierdzewnej, pompuje ścieki przez te komory, wytwarzając niemal stały przepływ w każdych warunkach - od podciśnienia do ciśnień wyższych od normalnie spotykanych w kanalizacji niskociśnieniowej.

The geometry of the pump not only produces a near vertical pump curve, but also allows passage of ground solids without clogging. The progressing cavity pump itself is based on the Moineau principle. A rotor turns within a stator, creating a sequence of sealed chambers. The rotor moves wastewater through these chambers at a nearly constant flow, over a wide range of conditions-from negative to abnormally high heads.
