LG-type pump main parts are: pump base, middle, rear section, impeller, guide vane sets, guide vane, guide vane, bearings, motor base, shaft, bearings, bushings, seal rings, balance drum, drum balance sets. (25LG, 32LG and 40LG three pumps do not balance and balance drum drum sets, but with a seal ring, mounted on the bottom of the packing chamber). Pump base, middle, rear section, impeller, guide vane sets, guide vane, guide vane, bearing, motor housing, bushings B, sealing rings are made of cast iron. The shaft is a high-quality alloy steel, the middle of the impeller, bushings B, balance drum, with the key and small round nut on the shaft of the rotor component composition, the lower end of the shaft and the sliding sleeve fitted sleeve A match, the upper end of the shaft with two angular contact ball bearings, thereby supporting the rotor assembly, the shaft of the upper and lower ends of the motor shaft coupling connection through the claw. Sealing means soft packing seal and mechanical seal. When soft packing seal, sleeve friction therewith prop is made of carbon steel, and after quenching multistage pumps, in order to increase the surface wear resistance. The impeller is made of cast iron, due to the unequal pressure on the front and rear wheel, there must be an axial force, the axial force to bear most of the balance drum. (25LG, 32LG and 40LG balanced by the seal rings pipeline bear) 32LG6.5-15x4 fire pump, a small portion of the remaining residual axial force by the end of the two-axis angular contact ball bearings to withstand the vertical multi 25LG3-10x8 stage pump, balance device consists of a balance drum and balanced drum sets composed can be replaced after wear. In the pump housing, respectively, on the middle of the ring with sealing ring and mouth to reduce water leakage back to the inlet portion of the high-pressure multi-stage pump 32LG6.5-15x3 can replace the sealing ring worn. Pump top of angular contact ball bearing calcium-based grease lubrication, the lower end of the sliding bearing (bush) with pumping of liquid lubrication, the rotational direction of the pump from the motor to rotate counterclockwise Anguo Shi Yuan Pump Co., Ltd. is set design, development, manufacturing, sales and service in one, Main: slurry pump, filter feed pump, filter pumps, filter pump, filter feed pump, D-type multi-stage pump, DG-type multi-stage pump, LG-type multi-stage pump, pipeline pumps, chemical pumps, slurry pumps, corrosion resistance, fluorine plastic chemical pumps and another mechanical seals, pump mechanical seal, WB2 type mechanical seals 20 series 64LG stand multistage centrifugal pumps Product Overview LG line vertical, single suction it. Domestic water for high-rise buildings, high-rise building fire water, factories, enterprises water, drainage, low-pressure boiler water recycling. Medium temperature pumping clean water or physical at 0 ℃ ~ 80 ℃ properties similar to liquid water. LG vertical multistage centrifugal pump model significance 25LG3-10x8 vertical multistage pump multistage pump _ _ high-rise buildings to pump provided by the Anguo City Pump Co., Ltd. Shi Yuan.
