Two types of blade pumps: single-action blade pump and double-action blade pump

[Asian pump network] Squeegee pump is a kind of positive displacement pump, centrifugal pump on the high-power fire truck water diversion device is widely used in the structure is relatively compact, in the type, it has a single role Squeegee pump, double-action blade pump, the following on these two types for everyone to introduce. Two types of blade pump: Single-action blade pump and double-action blade pump Single-action blade pump Single-action blade pump is mainly composed of rotor, stator, blades and other components, of which the rotor is eccentrically installed in Pump housing, the rotor blade direction is also provided with slots, and leaves in this slot, it is worth mentioning that it is free to slide, the rotor rotation, under the action of centrifugal force, the blade will Tightly pressed against the inner surface of the stator, so that several sealed working chambers are formed by the combination of the inner surface of the stator, the blades, the outer surface of the rotor and the end cap. When the rotor rotates in the correct direction, due to the eccentric rotor installation, the right half of the blade will gradually protrude, the working chamber between the leaves will also continue to grow, in addition, the left half of the blade Will be as the rotor rotates gradually by the inner surface of the stator into the slot, the working chamber between the leaves will be gradually reduced under the action of the pump chamber gas will be out from the end cap out of the rotor per revolution A week, it will complete a suction and discharge fluid. Second, double-action blade pump For double-action blade pump, the stator and rotor are concentric assembly, rather than eccentric installation, which is a single action scraper pump a big difference, the inner surface of the stator is It consists of two sections of short radius, two sections of long radius cylindrical surface and four sections of transitional surface connecting them instead of the simple cylindrical surface, which is another big difference between the double action blade pump and single action blade pump Department. Double action blade pump has two suction port and two discharge ports, they are staggered with respect to each other, symmetrically arranged, and single-action scraper pump is different, double-action scraper pump rotor per revolution to complete two suction and drainage fluid .
