Abstract
The invention belongs to the field of a centrifugal pump device, in particular to an integral impeller of a centrifugal pump and a processing method thereof. The integral impeller of the centrifugal pump is composed of a front cover board, a leaf blade and a rear cover board, and is characterized in that 3 to 12 protruding leaf blades are uniformly distributed on the rear cover board. The processing method comprises the following steps: molding 3 to 12 uniformly distributed and protruding leaf blades and a central shaft hole on the round rear cover board through all-in-once stamping and pressing to shape a whole leaf blade, and welding the whole leaf blade on the front cover board. The invention has the advantages of scientific and reasonable design, compact structure, the leaf blade molded through all-in-once stamping and pressing, convenient and rapid processing, high productivity, low production cost and smooth and even surface of the leaf blade; in addition, the operation of the centrifugal pump is steady and noiseless, thereby guaranteeing a better integral operation performance of the centrifugal pump.
Description
Technical field
The invention belongs to the centrifugal pump device field, particularly a kind of integral centrifugal pump impeller and processing method thereof.
Background technique
Centrifugal pump is widely used in the conveying of liquid material in industrial production, have the advantages such as conveying that simple in structure, processing ease, flow are easy to regulate and be applicable to multiple special nature material.The critical piece of centrifugal pump comprises impeller, pump case and pump shaft, wherein impeller is the core component of centrifugal pump, usually constitute by 3-12 sheet blade, can form a plurality of fluid passages between the blade, impeller drives high speed rotating to being positioned at interlobate fluid acting by pump shaft, fluid is thrown to the periphery by the impeller center under action of centrifugal force, discharge from exhaust port after pump case compiles.Existing impeller is by having or not cover plate can be divided into enclosed, half-closed and open type, and unshrouded impeller does not have cover plate in the blade both sides, and it is convenient to make simply, clean, and be applicable to and carry the material that contains relatively large suspended matter, but efficient is lower, and the fluid pressure of conveying is not high yet; Single shrouded wheel does not have cover plate in suction port one side, and at opposite side cover plate is arranged, and be applicable to that conveying easily precipitates or contain the material of particle, but efficient is also lower; General centrifugal pump impeller mostly is double shrouded wheel, double shrouded wheel is provided with cover plate in the blade both sides, and it has higher efficient for half-closed and unshrouded impeller, and liquid has elevated pressures, application area is also wider, and the centrifugal pump in the general industry production all adopts double shrouded wheel.At present, the blade of relatively large double shrouded wheel mostly is greatly and the moulding of back shroud integrally casting, and its blade surface is coarse, unsmooth, suffered resistance when having increased fluid and flowing reduces device efficiency thus, has increased energy consumption, and the casting process needed time is also longer, and manufacturing efficiency is low; More small-sized double shrouded wheel is welded on the back shroud after adopting the thin metal plate to curve blade one by one, the welding position of blade, angle etc. also are difficult to accomplish accurate assurance, cause the reduction of Impeller Machining accuracy of manufacturing, work efficiency is also extremely low, thereby has reduced the operations performance such as pressure, lift of centrifugal pump; Be easy to generate leakage between blade and the cover plate, cause unstable working condition, noise is higher.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of back shroud and blade once-through are provided, the course of working simple and fast, the work efficiency height, blade surface is smooth smooth, accurate integral centrifugal pump impeller of blade pitgh and angle and processing method thereof.
The present invention solves its technical problem and takes following technological scheme to realize:
This integral centrifugal pump impeller is made of front shroud, blade, back shroud, it is characterized in that: the blade of the uniform 3-12 of the being shaped on sheet of one projection on the back shroud.
And described blade water inlet end to water outlet end width increases gradually.
The integral centrifugal pump impeller processing method is characterized in that: adopt mould once to stamp out a uniform and protruding blade of 3-12 sheet and a central shaft hole on circular back shroud, become an integral blade, this integral blade is welded on the front shroud.
And, can stamp out stretchable holes simultaneously in blade water inlet end.
And described circular back shroud adopts the corrosion resistant plate of 0.5～1.0mm.
Advantage of the present invention and good effect are:
1. on back shroud, adopt mould once to stamp out the blade of 3-12 sheet projection, save blade with monolithic and be welded to loaded down with trivial details step on the back shroud one by one, easy to process, quick, adopt same mould can process a large amount of blades at short notice, the manufacturing efficiency height, be very suitable for producing in enormous quantities, greatly reduce cost of production.
2. adopt the one time punching molded method processing blade of stainless steel, the relative position between the blade and the angle of blade are accurate, the back shroud smooth surface of blade and one thereof is smooth, the precision of the whole manufacturing of impeller is higher, the steady noiseless of centrifugal pump running has guaranteed that centrifugal pump integral body has preferable operating characteristics.
3. blade and back shroud are the form of one, need not blade is welded on the back shroud one by one, can not produce because of between blade and the back shroud because of not prison welding or use for a long time and produce leakage, guarantee the stable working state that has of centrifugal pump.
4. design science of the present invention is reasonable, compact structure, and blade is one time punching molded, easy to process, quick, the manufacturing efficiency height, cost of production is low, blade surface is smooth smooth, and the steady noiseless of centrifugal pump running has guaranteed that centrifugal pump integral body has preferable operating characteristics.

Fig. 2 is the plan view of blade of the present invention;
Fig. 3 is that the A-A of Fig. 2 is to sectional drawing.
Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are further described:
This integral centrifugal pump impeller, constitute by front shroud 1, blade 2, back shroud 3, its inventive point is: the blade of the uniform 3-12 of the being shaped on sheet of one projection on the back shroud, in this fact Example 6 blades, individual blade has certain width, and blade water inlet end 4 to water outlet end 6 width increase gradually, have guaranteed can make liquid produce stronger centrifugal force by the stamping forming blade of corrosion resistant plate.The processing method of this integral centrifugal pump impeller is: adopt mould once to stamp out a uniform and protruding blade of 3-12 sheet and a central shaft hole 7 on circular back shroud, become an integral blade, this integral blade is welded on the front shroud, for be convenient to the drawing and forming of blade at stamping process, can stamp out stretchable holes 5 simultaneously at the water inlet end position, circular back shroud is the corrosion resistant plate of 0.5～1.0mm.Adopt process for stamping to produce this integral blade, convenient and swift, have higher production efficiency, impeller operates steadily, noise is low, has guaranteed that centrifugal pump integral body has preferable operating characteristics, has reduced cost of production, is suitable for applying.
