Abstract

DC60 (11/01/43) Impeller or compressor centrifugal pump including fixed housing, cam ring on the surface. The outside of the It's with a cam face and mounted in a fixed housing, pair of wall structures. Together with opposite ends Of the cam ring to make the pump cavity in the eccentric ring, a rotatable drive shaft built into the The housing that is fixed and extends into the inside of the pump cavity through a single wall structure, a rotator assembled into a cam ring and attached. Set on the drive shaft Moving for rotation is built into the body. Rotated to move within the radial from the rotor and work with the cam face of the cam ring to form a number One of the extendable cylinders Which one of the barrier structures is located on the inside of it With a suction inlet to the part of the cylinder Extended pump While the propeller travels radially outside Occurring on the inside of it, with a vent that exits at the The pump cylinder is in contact as the impeller travels in a radial direction. And the groove was tapered From the front end of the outlet in the direction In contrast to the direction of rotation of the rotator; Impeller centrifugal pumps with the above characteristics The groove is with the leading part. Into and the surface which is sloping inward In the vent Impeller or compressor centrifugal pumps including fixed housings, cam rings on the surface The outside of the It's with a cam face and mounted in a fixed housing, pair of wall structures.

Claims (3)

1.The impeller centrifugal pump consists of: fixed housing; A cam ring, which is built on its inner edge to the cam surface and attached to a fixed dial; A pair of retaining wall structures fit on opposite ends of the ball ring. Deform to make Formed a pump chamber inside a rotating camshaft mounted drive shaft inside a fixed housing. And extending into the engine room Through one of the wall structures together; The rotors are contained within the cam ring and are mounted on the drive shaft for rotating together; A certain number of impellers that are equal to the circumferential flux that slide. Is assembled in the body of the rotator To move vertically outside The radius from the rotor and together with the cam surface of the cam ring to form a certain number of extensible pump cylinders, at least one suction channel, which is built on the inner surface of one of the retaining walls. Channel Where the pump chamber extends as the impeller travels radially externally, and at least one outlet channel is created on the inner surface of the chamber. The pump touches as the impeller moves inward radially, the outlet port is structured so that it is Built with at least one hair-like groove tapered from the fore end of the vent. Exit in the opposite direction to the rotation direction of the rotor, where at least one such hairlike groove has been created with the import surface which Was sloping into the inside of the outlet channel, the such input part consists of At least one part of the frame is different. And the second, which are connected to each other 2. Impeller centrifugal pump, as requested, holds the right in Clause 1, where at least The first and the second funnels were created respectively with a curved and smooth surface where it was made. Let a gradual slope go into the inside of the outlet channel. 3. Impeller centrifugal pump as requested holds the right in Clause 1, where at least The first and second funnels were built with a number of flat surfaces that were sloped to Little by little into the inside of the discharge channel.
