LKN series addition of counterflow type cooling tower
Characteristics and technical data is introduced
A, LKN series square cooling tower design conditions:
1: water temperature 43 ℃ to 33 ℃ temperature. Water
Wet bulb temperature 28 ℃ dry bulb temperature 10 ℃ to 31.8 ℃ temperature drop
2: the atmospheric pressure P = 9.94 X 104 pa
3: the anti wind design < 14 m/s
4: the earthquake resistance design < 8 basic earthquake intensity
Second, LKN square cooling tower series features:
1, the structure of the system
Tower body metal artifacts: a tower body of the metal material adopt high strength high quality steel, hot-dip zinc treatment, light weight, good rigidity, materials comply with relevant national standards, the indicators parts interchangeability, convenient assembly, good stability, under the harsh environment can run normally for a long time.
Framework for metal parts are hot-dip zinc treatment, hot-dip zinc thickness 0.3 0.5 mm, corrosion resistance, oxidation resistance; All metal components are based on theoretical mechanics, mechanics of materials check design, novel structure, firm connection, convenient assembly, has a long service life.
Tower body surface artifacts: the reinforced glass fiber reinforced plastic composite materials (F.R.P) made of glass fiber reinforced plastic products, color uniformity, ageing resistance, not easily fade, is especially luster. Gloss surface gloss, 95-95 units, surface surface glue with world famous corporations' - the Netherlands, DSM company DSM 'import unsaturated polyester resin. Color imported Japan DIC ink "of a product, the color of embedded U.V.S. light stabilizer, can absorb ultraviolet (uv), gel layer containing light powder imported from the United States (DEGUSSA/AEROSIL 200/321293) thickness 0.3 0.5 mm. 4 -- 10 mm, the thickness of glass fiber reinforced plastic products bending strength by the national glass fiber reinforced plastic products quality supervision and inspection and test center testing more than 250 mpa, and convex arc stiffener board structure, modular design, glass fiber reinforced plastic products assembly of flexible, durable without deformation. The unique appearance design, combined with modern architecture.
2, heat exchange system
Flame retardant heat packing:
1, by the ultraviolet light resistance, chemical resistance, high quality modified P.V.C sheet by fully automatic vacuum blister, the performance indicators meet NDG88-89 plastic water spray packing technical regulations. Unique intersection double twill slot (CROSS DOUBLEFLUTED) corrugated design, good hydrophilicity, make the hot water flows through the filler surface to form thin water film, water and air contact more fully, so as to enhance the heat transfer performance, improve the cooling efficiency of cooling towers.
2, packing good flame retardant performance, via detecting oxygen index of the packing material is 38, the acuity of 28 is far higher than the national standard requirements.
3, water spray packing inverted "V" shape design, into pieces to assemble in the installation of the tower mode, to avoid the packing compression deformation caused by fouling; After assembly packing has had the effect of the heat, water, large distance don't jam the packing structure, both to reduce the wind resistance, and reduce the chance of a biological derivative.
4, design of the "hive structure" has guide effect, have good uniform ventilation effect, improve and stabilize the water heat exchange intensity, precise positioning spacing combination, easy to form with water flow through the surface of the large flow of water film, water exchange.
Unique closed water structure, choose high quality PVC material hot forming, in the domestic same industry leading level, effective return hot water vapor in the air out of the tower, greatly reduces the loss of drifting water, reduced the supply water of the water. LKN series cooling tower floating water loss rate is less than 0.001%.
Variable diameter sizing nozzle: planting water system USES the introduction of the latest technology production of nozzle as main components, the modified impunity nozzle selection of quality plastic injection forming, inside have no moving parts, corrosion resistance, ageing resistance. Work with low energy consumption, large caliber is not easy to jam, scaling, convenient disassembly, installation, and maintenance. Unique taper type design, make continuous uniform water distribution, formation and reliable "hollow" umbrella "solid cone" by water model, no water no dead Angle. Hot water evenly spread on the filler surface, effectively improve the heat exchange efficiency. Within the circle of foreign design, not easy jam, without cleaning, reducing the workload of maintenance.
4, drive system
Fan: for low speed space warp forward type aluminum alloy cooling tower dedicated fan. Fan is made of aluminum alloy sheet roll forming machine, blower fan are all adjustable Angle, can satisfy the customer different requirement of ventilation technology. Fan balance before shipment are through strict and positioning, to ensure its reliable performance. Four leaf type forward plate design, to make every piece of blade force is small, which has low noise, big air volume, high efficiency, power consumption province, the advantage of smooth operation.
Motor: fully enclosed self-cooling type &low noise cooling tower dedicated motor. Protection grade IP44, insulation class B, 380 (V) / 3 bits / 50 (HZ). Small volume, light weight, simple vertical installation, positioning and good starting performance, reliable operation, convenient maintenance. AD hoc motor shaft under the hot and humid environment of aprons, junction box, waterproof rubber gasket, installing special drain, ensure the motor from the wet, long running condition.
Electric machine frame: adopt international advanced design idea, the last position in the tower body steel structure frame, less bulk, convenient installation, good rigidity, small vibration, stable performance is high, is not affected by the glass fiber aging, not easy to damage the transmission parts.
Reducer: equipped with high-precision bearings, three layers of insurance oil seal, waterproof properties is good, bearing erosion to avoid moisture. Disc-shaped steel bracket and cast iron plate pulley design, compact structure, match with static balance checking, smooth operation, low noise. Unique upside-down installation, convenient maintenance, noise and service life are superior to similar products, maintenance nozzle is designed reducer, then
