The impeller of the cyclone pump designed by the design method can replace different blades according to the particle condition, so that the aim of changing the height and the length of the blades is fulfilled. The impeller of the vortex pump designed according to the design method well ensures the trafficability of the vortex pump, improves the flow condition in the pump, and improves the lift and efficiency of the vortex pump.
Description
Technical Field
The invention relates to the technical field of vortex pump impellers, in particular to a vortex pump impeller with guide rails and fixed blades.
Background
A vortex pump is a device that is named because of the swirling motion of the fluid inside it. The vortex pump is often used to pump complex media or fluids containing impurities, such as two-phase fluids containing trash, short fiber material, or feces. The working process of the cyclone pump is extremely complex three-dimensional, turbulent flow and two-phase flow, the excellent through-flow capacity of the cyclone pump is widely applied to sewage and dirt conveying, particularly a multiphase medium containing a certain proportion of gas can be conveyed, and the cyclone pump has excellent performance in mixed conveying of rural methane tanks, chemical gas-containing materials and the like.
The impeller of the vortex pump retracts in the chamber of the volute, so that no blade cavity has a spacious space, and because a large gap exists between the impeller and the volute, when the impeller rotates, the energy of liquid under the action of centrifugal force is increased, and the liquid entering between the blades moves together with the impeller under the pushing of the blades. The liquid near the top of the impeller outlet forms a through flow due to the larger centrifugal force, and the liquid in the middle of the impeller forms a circulating flow due to the smaller centrifugal force. Because the whole water pressing chamber of the cyclone pump is filled with circulating flow and through flow, and the circulating flow does not work on the fluid in a certain sense, the efficiency of the cyclone pump is reduced.

Compared with the traditional impeller vortex pump, the vortex pump blade can be replaced as required, so that the position, the height and the length of the blade can be changed, and the purpose of improving the lift and the efficiency is achieved.
In order to solve the problems in the prior art, the invention provides a semi-open impeller with guide rails and fixed blades, which comprises a rear cover plate, a hub, a guide rail and blades, wherein the guide rail is provided with a guide rail mounting groove, bolt holes, counter bores and steps, the counter bores are formed in the mounting groove, the steps are arranged on the side edges of the counter bores, the bolt holes are formed in the steps, and the blades are provided with blade mounting grooves.
Furthermore, the number of the guide rails is 8, and the guide rails are uniformly distributed on the rear cover plate.
Preferably, the bolt hole diameter is 5 mm.
Further, the guide rail is fixed on the rear cover plate through bolt connection.
Further, the guide rail and the blade are provided with mounting grooves.
Furthermore, the guide rail is a contained surface, the blade is a contained surface, and the guide rail and the blade are in clearance fit.
Furthermore, the position of the blade is adjustable, and the blade is detachably arranged on the guide rail.
The further technical scheme of the invention is as follows: the position of the blade can be adjusted according to different particles; meanwhile, the length of the blade can be adjusted by replacing the blade, so that the purposes of improving the flowing condition in the pump and improving the lift and efficiency of the swirl pump are achieved.
