The louvers made oJ: rigid FRP t>revent external splashes of water drops and regulate the flow oJ: air. 1 :1.-4 lrilling The newly developed filling for the cross-flow type cooling tower is membrane filling having excellent performance, and can withstands many years of service because of the use of rigid PVC excelling in weather resistance. 1-5 Fait The alumioum-made axial fan has a variable structure whereby the angle can be freely adjusted. It is extremely lightweight, and excels in corrosion resistance. 'It is made with highly waterproof specifications 'for the cooling tower. :I. -5 Speed ",,,duoer The two-stage type designed and manufactured exclusively for the cooling tower has been adopted. All gears in use are helical gears and spiral bevel gears with hardened tooth flanks, heeding adequate strength and quiet operation. In addition, due to the original oil dam structure adopted at the top of the housing. the upper bearing is also lubricated with oil, requiring no grease filling, so that maintenance man-hour'! are reduced. 1-7 Drive shaft :rhe drive shaft that transmits rotations of the motor to the speed reducer has an extremely simple structure, in which two hubs, one center ring and two pairs of disk packs are coupled with several reamer bolts, requiring no lubrication because the components have no friction parts. Also, since each member is made of SUS, it withstands continuous use "vep in a lOot hUmidity atmosphere. 2 2.

Tower body Check that the inspection doors inside and outside of tne tower are closed. b. Drive section 1) Check to see if the lubricating oil of the speed reducer is at the regular oil level position,'and check the oil for contamination.

Fully open the air vent valve of each piping section to remove air having accumulated in the piping so that the whole circulating water system is adequately filled with water. b. After starting operation, gradually open the circulating water valve ana make adjustments so that the rated water flow is reached. c. Since the upper distribution basins available at four places per cell are provided with water level valves, open and close the butterfly valves and make adjustments so that the water levels of the upper distribution basins at the four places become uniform. (The water levels of the upper distribution basins should be approx. 70rnm at the. rated water flow.) 4-2 Priving the fan I /f\\ CAUTION When st:arting the fan, carafully check around the watsr inlet and outlet of the cooling towar for foreign macter. Be aware that if lIIatte.l: remains aroUnd the ontlet, it may drop in the tOlfer due to vibrations of the fan, etc./ and be shot by the fan, or the fan'lIIaY be damaged. Istart the fans one by one. When steady operation begins·, measure each phase current, and check to see i.f operation is performed within the range of the rated current value on the nameplate of the motor. 1 I , 5. Precautions in operation 5-1 Perfoxmance Since the performance of the cooling tower is affected by fluctuations in the circulating water flow, always keep the rated water flow. Be to prevent occurrences of algae r scales, in the tower. 5-2 E'unction Be extremely careful with vibrations, sounds, cooling water temperature and electrical current during operation, and always check that there is nO abnormality. Since vibration and noise sOurces are mainly a result of the drive section consisting of the speed reducer, motor aild fan, do not overlook even a triVial abnor,!,ality. 8 6. Maintenance and control 6 CAUTION 1. When inspecting the motor, be Suxe to turn off the power. Since . t:1l.e_ fan may start sUddenly dua to automatic operation oJ: the like even if it is stopped, be sure to check that the power i.s off. 2. If an antifree2:ing hellte:/: is. attached, ,, turn off the power of the heater when performing inspecti.on. 3. Fox work at high elevations use safety. equ.ipment such as a helmet. 6-1 DriVG section a. Check for the presence or absence of abnormal sounds and vibrations, . and the oil level every day. b. Replace all speed reducer oil 500 hours after starting operation, and then replace it again 2500 hours after that. Then, replace used oil with new oil every 5000 hours. When injecting oil, be extra careful not to mix impurities and foreign matter, and the like. c. HOW to replace oil i. Place an oil pan (to be prepared by you) under the oil discharge valve, and fully open the oil level check valve and oil discharge valve to drain the oil. ii. After that, close the 011 discharge valve, and remove the cap from the lubricating opening, and slowly fifl new oil. iii.

Perform cleaning by showering from, the outside. 6-7 Casing £rameii(ork Since the corrosion conditions of the casing framework vary depending on the check for the presence or absence of rust once a year.' 6-8 Circulating wAter a. Since the circula ting water should basically be pH6. 5 - 8.2, check Eor mixing of matter that adversely affects the water quality of the water once a month, and immediately remove it if any. b. Check every day to $ee if the amount of supply water is proper when also checking the water basin. 6-9 Water quality , Maintenance is indispensable in the ability of the cooling tower to perform water quality control, inclUding U$e of water treating agents in cooling water and blow-down as measures to prevent adhesion of scales and slime to the filling surface, which can be the main factors in performance deterioration of the cooling tower. Since the heat exchange in the cooling tower by direct contact between the air and hot water cleans the air conversely, the water quality of the circulating wateJ: is gJ:eatly affected by the air around the installed coolioq tower. For the cooling water system, total water treatment is required because problems of scales, slime and corrosion do not ocem: separately but occur in connection with each other. If the water contains iron, total hardness components, silica, organic substances, etc., hard scales of carbonate and silica adhere to the surface of the heat exchanger due to concentration, reSUlting in deterioration of the thermal efficiencies of the refrigerator and condenser. • 9-1 shows the proper water quality control standards of water. Fig. 9-2 shows the relationship between the rate of concentration, amount of supply water and amount of If the water is not treated with use of Chemical agents, control the blow-down in the'concentration range of 3 - 4 under general working conditions. 51--1----;-----+-----1---,.----;.-----;.------; f '.

The theoretical formula of a cooling tower All the intermediary quantity of heat accompanied by substance movement between the water and air in a cooling tower is proportional to an Enthalpy difference, and is expressed as follows. Gdh= Ka (hw-h) dY If movement of all intermediary quantity of heat shall be performed only in tbe evaporation latent heat of water -db/Cwo dtw=L/G=N The following formula is obtained from (l) and (2) formulas.

It asks for U/N or U. Next, the filler capacity of a cooling tower is decided arbitrarily, and if it substitutes for (8) formulas, a required Ka value can be found. Filler performance formula obtained by this required Ka value and experiment Kao is compared, and if set to Kao/Ka >= 1, specification will be satisfied on quantity-of-heat calculation.
