There are many methods for repairing metal centrifugal pump impellers, such as ARC polymer composite coating, powder coating (welding), epoxy resin coating, and rubber and nylon composite repair. There are also stainless steel inlays, surfacing and so on.


Common repair methods:


1, copper wire repair method

For pinhole-shaped cavitation, as long as the holes are not connected into a piece, the pinhole can be punched with a copper wire, and the trowel can be used to smear. Before processing, the surface of the blade should be cleaned with rust and dirt, then the oxygen in the pores should be blown off with the oxygen-acetylene flame, and then the appropriate thickness of the copper wire is filled into the hole, and the copper is tapped with a pointed hammer. The wire is squeezed and squeezed into the hole and flattened with a file.


2, gas welding repair method

The impeller is placed on a charcoal fire and heated to 400-500 ° C. The tin is hung at the repaired joint, and then the brass filament is melted into the groove or hole to be repaired with an oxygen-acetylene flame. After the welding, the charcoal fire is removed, and asbestos is removed. The board is covered with insulation to allow the blades to cool slowly to avoid cracking. After welding, the boring tool is used to finish the machining according to the original contour.


3, epoxy resin repair method

According to the mixing ratio and order, take appropriate amount of epoxy resin, ethylenediamine, dibutyl phthalate and acetone in a glassware and mix well. Pay attention to the viscosity of the adhesive when mixing, and add the amount of acetone in an appropriate amount. The prepared epoxy resin is used up within 20-30 minutes. Use a wool brush to pick up the epoxy resin, brush the surface of the blade with the blisters and pores. When brushing, use a sharp cone to gently squeeze out the blisters and the bubbles in the middle of the pores. Apply as much as possible and gently scrape with a scraper. real. After the epoxy resin is cured for 1-2 hours, brush it again for 2 to 3 times. When applying the brush once, be sure to make the surface of the blade smooth and smooth. After the painting is finished, the impeller is placed in an environment of 20-30 ° C and a relatively low relative humidity, and is slowly maintained for 48 hours. After the epoxy resin is completely cured, the contour of the impeller and the protrusion on the surface layer are trimmed with a file or a sander.


4, accelerated steel repair method

Quick-formed steel is a cement-like adhesive repair agent before curing. It has high strength, high hardness, no shrinkage and no rust after curing. It is suitable for filling pores, cracks, blisters, etc. in steel, iron and other metal materials. Repaired with a strong bonding effect. Before repairing, clean the rough rust and dirt around the repaired area and roughen it. The colloid in the plastic tube of the quick-form steel is taken out, and the materials of the two different colors of the core and the outer skin of the gel are quickly and fully smashed into one color (about 1 to 2 min) to achieve heat generation and softness. Before the colloidal steel colloid is to be solidified, it is firmly adhered to the repairing place, and is compacted with force (hand or tool) multiple times during the solidification process of the colloid to enhance the adhesion of the adhesive to the blade. After the fusible steel is hardened, it is flattened with a file.


5, surfacing repair method

Before surfacing, grind the cavitation part with a grinder, and clean the surface of the rust and debris until the bright metal body is exposed, so that the surfacing layer and the blade are more firmly combined. After cleaning, the impeller is placed in a charcoal fire for preheating. Use the same electrode or stainless steel electrode as the blade material, without peeling, damage, keep dry, remove moisture, so as to avoid air holes in the weld. When surfacing, it is necessary to adopt round-trip welding, or stratified cross-welding can be adopted, and the amount of welding should be less at each time to prevent the blade from being concentrated by heat and causing stress deformation. After repair welding, the blade is trimmed with a sander. The repaired impeller must be subjected to a static balance test. In order to prevent the impeller from rotating at a high speed, the centrifugal force is generated due to the imbalance of the additional weight to cause the water pump to vibrate.





1. The distinct characteristic of our FGD engineering pump is double - casing and rubber lined technology. Double - casing structure refers that the pump body is divided into outer pump shell and inner lining. The former bears pressure and insulates slurry. The latter contact abrasive and corrosive slurry. We only need to replace the worn out inner liner.


2. FGD engineering pump is mainly used to transport limestone and gypsum slurry. This requires the wet part performance will not only in anti - abrasive but also in anti - corrosive. Therefore, the wet parts ( such as impeller , volute liner and frame plate insert, etc . ) adopt A49 combined with rubber material.


3. The engineering practice shows that the service life of components made by ours is triple or even higher than the traditional Cr30A product or duplex stainless steel pump.





Fuel gas Desulphurization Pump/FGD system Pump

TDT series axial inhalation single stage single suction centrifugal desulphurization pump can be widely

used to deliver limestone or gypsum grout for fas desulphurization systems of heat-engine plants,

aluminium manufacturers and oil refines. In the grout , the acceptable content of chlorine ion is

60000ppm ,and the acceotable Ph value is between 2.5-13 .
