used in refurbishment repairing Baogang Baiyun Ebo iron mine slurry pump.
In June,2016.The eliminated & waste slurry pump and guard plate of Baogang Group Baiyun Ebo iron mine warehouse were stored up for too many,
the company devote itself to save resources and reduce waste,thus they entrust Xiangyang City Hundred Shield Coating Material Co.,Ltd to do the
rebuilding & refurbishment repairing and recycling for the partial slurry pump volute casing and guard plate.We found that,if passing rebuilding
& refurbishment treatment,the partial stock & eliminated pumping element can at least replace even exceed the service life of new pumps by inspecting,
if overall elimination,buy the new pumps again,the costs will increase too much,the Baogang Group chooses BD7045 slurry pump repair anti corrosion
abrasion resistant coating from Xiangyang City Hundred Shield Coating Material Co.,Ltd as the rebuilding & refurbishment materials.
Slurry pump materials: high chromium alloy
The workpiece before repairing: guard plate,volute casing is serious abrasion,partial volute casing has already worn through,
the feed inlet part is serious deletion.
Maintenance difficulties:There is no sealing ring between the front & back guard plate of this pump and volute casing,it depends on taper for sealing
completely,the accuracy requirement is high.
Material selection: BD7045 slurry pump repair wear corrosion resistant coating
Construction tools: Angle grinder,wire brush,grinding wheel,troweling knife,plastic knife,rubber hammer,special rounding tools,hair brush,
electronic scale,drying oven.
Auxiliary materials:Cleaning agent,duster cloth,gloves.
Construction procedure:
1.Do the sand blasting treatment for the surface of pumping element,clean it with cleaning agent and dry it by airing,obtains clean,dry and
coarse surface.
2.According to the specified ratio,weigh the weight of high strength special prime coat and mix it uniformly,and wait for the prime coat curing,when the
temperature is low,can heat it up to promote the prime coat curing.
3.According to the specified ratio,weigh the weight of BD7045 slurry pump repair anti abrasion corrosion resistant coating and mix it uniformly,
make the mixed uniformly materials be coating on the pending-repair parts,and use the special rounding tools to trim the coating surface to be smooth,
achieve the surface mooth and flat.
4.BD7045 slurry pump repair wear & corrosion resistant coating can be initial curing at room temperature,after initial curing,heat it up to the temperature of
80 degree slowly and keep this temperature for 2-3 hours,only in this way,it can improve 30% combination property,generally it can exceed the service life
of new pumps(if the condition is allowed,try to use the way of heating for curing).
5.Trim the matching parts to reach to the assembly size.
