epoxy compound coatings used in power plant desulfurization system slurry recycle pump ceramic
rubber lining pipeline repairing and protecting
According to the requirements of the state environmental protection department,thermal power plant,chemical plants and other emission
substandard enterprises all need using desulfurization system to solve the emission problems.There is an important equipment in this
system--slurry circulating pump,its running state influences the whole system whether it is normal or not directly.At the same time,
the slurry circulating pump is also a large energy consumption,the power consumption per year for a slurry pump of a whole year
uninterrupted operation is up to 500 kw,in the process of long time running,the impeller surface suffers from wear,corrosion,cavitation etc.
damage,the blade will wear thin,indentation (corrosion),even appear gaps gradually.These indentation and gaps will gradually expand to
cause the structural damage,eventually led to the impeller scrap,at the same time,it will also reduce the efficiency of the pump seriously.
The indentation and rough of impeller surface increase the overflowing resistance.The impeller gaps will cause a large number of eddy,
the rate of flow reduced,consumes energy.The above reasons will consume more than 6-7% energy,500 Kw for example,it will consume
over 300,000 degrees power more than others,as the slurry pump's working condition is very bad,general the impeller will need to change
or repair for running a year or two.The material of impeller is special and cost expensive,it will cost more than 200 thousand for imported
pump changing the impeller,even though for domestic production pump, it will also cost about 100 thousand.
According to the previous repair methods--overlaying(easy to cause blowout),in the construction of energy-saving society today,
improve the efficiency of circulating pump,improve the maintenance technology for power plant,petrochemical and other enterprises to
reduce auxiliary power,save the maintenance cost both has great economic benefit and great social significance.
So these running slurry circulating pump impeller need repairing, energy conservation and renovation in time.
Solution: According to the slurry circulating pump working environment,using BD7053 desulfurization slurry circulating pump anti chemical
wear corrosion resistant repair compound epoxy coating can solve the mechanical abrasion, chemical corrosion and erosion problems
very effectively,restore the impeller surface quality,prolong service life, improve the pump running state,improve the pump efficiency.
Range of application for BD7053 slurry recycle pump absorption tower pipeline rubber lining wearing resistant
repair compound epoxy coating:
Special used in the preparation and repairing of anti wearing abrasion resistant coatings of power plant desulfuration system
equipment desulfurization absorption tower and slurry circulation pipeline ceramic rubber lining.
