Description
Technical field
The invention belongs to centrifugal pump impeller cover board burnishing device, especially a kind of centrifugal pump impeller cover board efficiently polishes dress
It sets.
Background technique
Currently, most domestic centrifugal pump impeller still uses traditional sand casting process, impeller cover surface usually compared with
It is coarse.And core component of the impeller as centrifugal pump, roughness have large effect to the performance of unit.Reduce impeller cover
Hydraulic loss and mechanical loss of the roughness of plate surface to reducing in impeller improve unit efficiency and play an important roll.To mention
The credit rating on high flow passage components surface, needs to polish impeller cover.Impeller is beaten using traditional-handwork technique
When grinding and polishing light, dynamics and direction are not easy to control, and more demanding to Benchwork, polishing efficiency is relatively low.
Abrasive flow machining is to flow through workpiece surface under a certain pressure repeatedly by carrying the liquid of viscoelastic matrix medium
The special process of polishing, the chemical property of abrasive material is highly stable in abrasive Flow Machining, and part material is flowed repeatedly by abrasive grain
Removal, after grinding, surface stress substantially reduces.Abrasive Flow removal material is very clean, and workpiece surface is defective
Place will not leave behind other impurity to fill and lead up, and same abrasive material can be used to process, from a workpiece in the workpiece of unlike material
The material of upper removal will not leave on other surfaces.But existing centrifugal pump impeller cover board burnishing device, it needs
Abrasive grain mixing plant, piping connection is also more, and apparatus structure is complicated, volume is larger, higher cost.
Summary of the invention

Technical concept of the invention are as follows: an a total of motor of whole device, a transmission shaft, motor by shaft coupling with
It is driven axis connection.The motor of described device is rotated by bottom driving axis impeller, and impeller passes through key and impeller nut and biography
Moving axis connection, the centrifugal force generated when wheel rotation can drive the fluid in impeller to flow out from impeller outlet, reach certain and turn
Speed, abrasive material are subject to centrifugal forces, and are flowed out from abrasive material case, into runner case, polish workpiece, then by abrasive material case entrance stream
It returns.Fluid used in device is a kind of abrasive Flow, i.e., some abrasive medias are had in fluid, when abrasive material moves, impeller cover
The fluid on surface can polish to impeller surface, polished, remove burr.To avoid choma gap from crossing little particle to impeller port ring
Locate excessive polishing, impeller port ring gap is 3~5mm；Due to using one to shunt abrasive material into three formula current dividers at tunnel inlets, and
Runner height is very low, and be thus effectively controlled abrasive material is influenced by gravity decline, so that the abrasive grain in fluid enters stream
Road is evenly distributed substantially.
Beneficial effects of the present invention are mainly manifested in: 1, the present invention provides a kind of centrifugal pump impeller cover board burnishing device,
Self-loopa can be achieved in device, save sanding and polishing cost, reduce manpower and material resources.2, the present invention devises a kind of very efficient
Runner can make abrasive grain in the bottom of impeller cover, keep the polishing of impeller, polishing more efficient.3, apparatus of the present invention structure letter
Single, compact, easy to operate, long service life, and polishing effect is good, reduces manufacturing cost and use cost.
