First, the application introduction LP-type pump vertical drainage pump, the pump covers an area of ​​small, easy to use, the basic low cost. Pump impeller immersed in the fluid being drawn, start without irrigation. The pump is suitable for pumping non-corrosive, the temperature is below 60 ℃, suspended solids (non-fiber, non-abrasive) content of less than 150mg / t of sewage or wastewater. LPT pump is based on the LP-type pump, an increase of shaft sleeve. The casing is filled with lubricating water, this pump can be pumping sewage temperature below 60 ℃, containing a certain amount of solid particles (such as iron filings, fine sand, pulverized coal and other abrasive particles), the maximum particle size of 2mm, impurities up to 2g / T liter. The two-stage pump lubrication water pressure should not be less than half the working pressure. LP-type, LPT-type pump can be widely used in municipal engineering, metallurgical steel, mining, water, power plants and farmland water conservancy projects. Both performance parameters, installation dimensions exactly the same, impeller, guide instead switch to wear-resistant materials, shaft 45 steel. Clockwise rotation from the motor to the pump, the pump outlet diameter is equal to or greater than 250 with anti-reversing device. Second, the model meaning 4LP-20 × 2 40 --- outlet diameter 40mm LP --- vertical drainage sewage pump 20 --- single-stage or more than the speed divided by 10 integer 2 ---- series Third, the performance range Flow: 3-2000m3 / h Head: 10-70m Fourth, the product structure Pump structure consists of 4 parts: (1) transmission part (2) energy conversion part (3) water transport section (4) Shaft seal part Transmission parts include: motor bracket, coupling parts, drive shaft, the intermediate shaft, pump shaft, coupling, coupling nut A, coupling nut B, the semi-circular snap ring and bearing components. Bearing components from the drive sleeve, bearing housing, tapered roller bearings and single row radial ball bearings and other components. Energy conversion section includes: pump cover, impeller, pressure chamber (volute casing or vane) and impeller. Water part includes: Yang pipe, bearing bracket. Pump shaft seal: The pump shaft seal packing or skeleton rubber seal to seal the liquid does not leak to foreign exchange. As the name implies, Round Molded Graphiteis a cylindrical product of graphite electrode, which is made of graphite block materials by crushing, screening, batching, shaping, cooling, roasting, dipping and graphitization of post section petroleum coke and medium temperature coal tar pitch. It has the advantages of high temperature resistance, corrosion resistance, good conductivity and light weight. It is mainly used for large DC resistance furnaces, blast furnace bricks, conductive electrodes, lining anti-corrosion and other purposes.
