Compressed air injection sewerage pump - has air sluice controlled by mini-float micro valve and impulse generator obtaining greater capacity

摘要

The aero-ejector for lifting waste water to a higher level, facilitates the handling of solid debris, has increased capacity, and incorporates a three-way valve which is actuated via mini-float, micro-valve and impulsion deriving from micro-valve operation. The unit comprises a chamber with resp. valved inlet and outlet conduits, a compressed air sluice which effects chamber communication with the atmosphere or an external compressed air supply, the above float and micro-valve, and an impulse generator which emits pneumatic impulsions of specific duration and which in turn control the position of the sluice. Pref. the float is sheathed in supply waterproof material attached to the chamber, the micro-valve and the generator are in a sealed housing and the housing with the sheathed float form a mono-bloc fixed to the chamber floor.
