Common desulphurization pump is horizontal cantilever type single-stage single-suction centrifugal pump, is designed to transport corrosive medium containing fine particles and design development, desulphurization pump common material for plastic pump (such as common material for uhmw-pe) and metal pump (common material for Cr30, 2507, etc.), material flow requirements for abrasion resistance, corrosion resistance, impact resistance, because the desulfurization pump discharge valve, in order to prevent the huge water hammer effect of liquid, so the pump body impact resistance), heat resistance (generally is minus 20 degrees to 90 degrees c), the northern request machine without external cooling water system, provide the cooling pump body inside.
Desulphurization pump is a pump, can adapt to different work conditions such as acid, alkaline cleaning liquid or slurry transportation; Smelting industry all kinds of corrosive slurry; Sulfuric acid industry of dilute acid; The environmental protection industry wastewater, etc. This pump is corrosion resistance and wear resistance, use very extensive. Has the following features:
1) strong wear resistance, flow components are all made of steel lining ultra-high molecular weight polyethylene (uhmw-pe) manufacturing, ultra-high molecular weight polyethylene (uhmw-pe) wear resistance among the top of the plastic, than nylon 66 (PA66), polytetrafluoroethylene (PTFE) 4 times, is carbon steel, stainless steel wear resistance of 7 to 10 times.
2) a strong resistance to impact, the impact strength of ultra-high molecular weight polyethylene first on the list of general engineering plastics is (acrylonitrile/butadiene/styrene copolymer (ABS) five times, and can maintain stability under 196 ℃ below zero, it is not by any other plastic feature.
3) excellent corrosion resistance: the pump in a certain temperature and the concentration range can all kinds of corrosive medium (acid), alkali, salt and organic solvents, at 20 ℃ and 90 ℃ for 80 kinds of organic solvent impregnated 30 d. Appearance without any abnormal phenomenon, and other physical properties are almost no change.
4) no noise: ultra-high molecular weight polyethylene impact energy absorbing peak for plastic, censored sex good, thus maximum limit reduced in the process of conveying liquid flow noise.
5) safe and reliable, no toxin decomposition: the pump USES ultra-high molecular weight polyethylene (uhmw-pe) chemical performance is extremely stable, so is suitable for use in the food industry.
6) low coefficient of friction, friction within the pump system for only 0.07 to 0.07, it has self lubrication. Under the condition of the water lubrication, the kinetic friction coefficient than half PA66 and lower polyformaldehyde (POM). When in the form of sliding or rotating job, than steel and brass after add the lubricating oil lubrication.
7) anti adhesion: ultra-high molecular weight polyethylene (uhmw-pe) viscous resistance is extremely good, adhesion resistance of PTFE and therefore when some high viscosity medium also performed very well.
