Desulfurization pump features and materials
[Asia Pump Network News] Desulfurization pump is a pump with strong corrosion resistance, widely used in corrosive liquid transportation industry, is a kind of universal equipment pump. Why desulfurization pump will have such a good corrosion resistance it? We have to understand the surface of desulfurization pump material and characteristics. Desulfurization pump production material: desulfurization pump is a cantilever single-stage single suction centrifugal pump, is designed for the delivery of corrosive media containing fine particles and design and development, the pump is made of steel-lined ultra-high molecular weight polyethylene (UHMW-PE) , The material is the latest generation of pump corrosion resistant engineering plastics, the most prominent advantage is that it has the most excellent wear resistance in all plastics, impact resistance (especially low temperature impact). Degeneration (resistance to environmental stress cracking) and excellent corrosion resistance. Features: Desulfurization pump is a pump that can adapt to a variety of working conditions, such as conveying acid, alkaline liquid or slurry; smelting industry, a variety of corrosive pulp; sulfuric acid various types of acid industry; the environmental protection industry Such as sewage. The pump is both resistant to corrosion and wear, the use of a very wide range. Has the following characteristics: 1) strong wear resistance: the flow of parts are made of steel-lined ultra-high molecular weight polyethylene (UHMW-PE) manufacturing, UHMW-PE wear resistance of plastic first, 4 times higher than nylon 66 (PA66) and polytetrafluoroethylene (PTFE), which is 7-10 times of that of carbon steel and stainless steel. 2) Strong impact resistance: The impact strength of UHMWPE is the first among general engineering plastics, which is 5 times of ABS (ABS) and can work under minus 196 ℃ stable, which is not the characteristics of any other plastic. 3) Excellent corrosion resistance: The pump can withstand a variety of corrosive media (acids, alkalis, salts) and organic solvents at a certain temperature and concentration range, and soak in 80 kinds of organic solvents at 20 ℃ and 90 ℃ for 30 days. Appearance without any abnormalities, other physical properties almost no change. 4) no noise: UHMW polyethylene impact energy absorption of the highest value in the plastic, good sound-deadening, thus minimizing the transmission of liquid generated during the noise. 5) Safe and reliable, toxin-free decomposition: Ultra-high molecular weight polyethylene (UHMW-PE) used in this pump has extremely stable chemical properties and is therefore also suitable for use in the food industry. 6) low coefficient of friction: the pump's internal friction system is only 0.07-0.11, it is self-lubricating. Under water-lubricated conditions, it has a lower coefficient of kinetic friction than PA66 and POM. When working in a sliding or turning form, lubricity is better than when steel and brass are lubricated. 7) good anti-sticking: Ultra-high molecular weight polyethylene (UHMW-PE) excellent anti-sticking, anti-adhesion capacity and PTFE equivalent, it is conveying some high viscosity medium also outstanding.
