Rotary blade meshing pump core and rotary blade meshing pump

Abstract

The invention discloses a rotary blade meshing pump core. The rotary blade meshing pump core comprises a flow guide cone and supporting plates; the flow guide cone is axially provided with a through rotating shaft hole; rotary plate grooves are radially formed in the rear portion of the supporting plate and the side wall, corresponding to the position of the supporting plate, of the flow guide cone, and a rotary plate is arranged in the rotary plate groove; three or more than three inclined rotating blade meshing grooves are formed in the rotary plate in the radial direction; a rotating part comprises a shell body and a rotating shaft; and a rotary blade can be meshed with the rotary blade meshing groove through rotation, and a rotary part water inlet is formed in the shell body at the rear part of the rotary blade. The rotary blade meshing pump core has the beneficial effects that the principle that the rotary blades and the rotary plates are meshed with each other is utilized, so that the rotating movement of the rotating blades is more converted into the axial movement of a liquid. The rotary blade meshing pump comprises the rotary blade meshing pump core, a front pump shell anda rear pump shell, wherein a pump water inlet is formed in the front end of the front pump shell, and a pump water outlet is formed in the side wall of the rear pump shell. The rotary vane mesh pumphas the beneficial effects that under the condition that the size is not increased, the rotary vane mesh pump has the advantages of being larger in flow and higher in lift.

Description

Technical field [0001] The invention relates to the technical field of pumps, in particular to a rotary vane meshing pump core and a rotary vane meshing pump. Background technique [0002] Pumps are general-purpose mechanical equipment that transport fluids or pressurize liquids, and are a major product in the machinery industry. The application markets of pumps mainly include sewage treatment, petrochemical, power industry, agriculture and domestic pumps. [0003] At present, there are many types of pumps on the market, mainly including positive displacement pumps, centrifugal pumps, axial flow pumps and mixed flow pumps. Positive displacement pumps rely on working parts such as pistons, plungers, diaphragms, gears or vanes to reciprocate or rotate in the pump body to increase and decrease the volume of several working chambers in the pump body to realize the suction and discharge of liquid. The change in the volume of its working chamber is used to transfer energy, and its flow...

Problems solved by technology

If the size is too large, it will be inconvenient to use, install, maintain, and transport. Not only will the operation and maintenance cost be high, but the comfort experienced by users during use will also be poor.

If the size is reduced, the direct cost is the reduction of the flow rate, which means that it will take longer to pump the same amount of liquid, that is, the time cost is higher. From an engineering point of view, the cost of time cost is difficult to predict
