Routine maintenance and winterizing winterizing method measures the cooling tower time tower into the October, is already approaching winter. Temperature is gradually lowered, for frost protection of cooling towers and other large logical devices mentioned first agenda. Daily minimum temperature during the first 10 or less is usually referred to as the winter run of the cooling tower. Prevent the cooling system to produce damage, first from the design stage to grab the infrastructure installation, then the more important key lies in the maintenance of cooling towers together with the maintenance and operation from two aspects, the practical implementation of the measures. Operation and maintenance aspects of freezing measures: 1. Check before winter, maintenance and ready to run before the arrival of winter, but the actors deal with the cooling tower tower for inspection and maintenance, eliminate defects tend to form frost damage, and make the relevant preparatory work for? are: (1) the distribution channel of fracture, blockage, leakage, nozzle off, blocking, not the splash plate on the splash plate shedding, skew, pipe flanges, valves, leakage and other defects to conduct a more thorough treatment, (2) to take measures to block the seal for retaining canopies defects, (3) the deflector disabled persons be removed, and (4) of the antifreeze communication pipe, gate, cooling tower frost distribution channel, nozzles and other facilities inspect, test the water; (5) weather boards regulating water gate, playing ice bars and other facilities and tools for inspection, repair, filled. 2. The preparation and the correct implementation of the "cooling tower winter operation plan" cooling tower before running into the winter period, should prepare a "cooling tower winter operation plan" submitted to the examination and approval, and cooling towers to be implemented correctly. Winter run program should include: determining when to stop running which tower, which always run tower, which tower to adjust when running, to develop frost protection measures outage cooling system, developed and run "Peak Tower" of frost protection measures . 3. Cooling tower outage winter measures (1) cooling tower in the winter period should not be run at frequent starting and stopping manner "tune bee." (2) cooling tower winter outage should be selected to operate at relatively high temperatures, for example at noon and the like. (3) The generators stop and must stop tower operation, stop and stop the tower should be operated simultaneously, or to stop the tower Cooling tower after the shutdown. The lowest temperature in winter run winter cooling tower water temperature is generally not less than 15.0, we do have experience in and grasp the situation has not less than l000, 5. minimal watering in winter run density cooling tower design should be kept in Winter water spray density, and appropriate to increase. 6. The increased water spray apparatus outer shaft with water cooling tower with five stops in the middle of the shaft may be considered to run the cooling tower. The apparatus according to the specific circumstances, should be timely to the outer ring of the cooling tower with antifreeze dedicated sink with water pipes, nozzles and other inputs operation. 7. Suspension and adjust the windshield with weather conditions and thermal loads (power load) changes, timely adjust the suspension and windshield, controlling air flow into the cooling tower is one of the effective and reliable measures. The main standard cooling tower suspension and adjust the windshield is: watering device at a steam temperature measurement should be o 0C or more, the cooling water temperature should be not more than 10 -150C large number of ice. Adjust the windshield work should be "three Le" ground temperature, ground inspection, ground adjustment, both to avoid freezing of the cooling tower, and it helps the economy. 8. Clear the ice water spray cooling tower hanging means for generating a hanging ice, should be in time to prevent widening. Clear ice hanging methods are: increasing the local hang ice spraying consistency make ice melt. Increasing the cooling tower hanging ice windshield, reducing the amount of cold air into the ice to melt so artificial playing ice, three. Three methods, should give priority to the former two, as the artificial playing ice water spray apparatus for forming easy to damage, and by the tool length limit, can only hang on the perimeter to clear ice cooling tower water spray apparatus. Artificial playing ice tools are playing ice bar, the length of about four meters, made of bamboo or perennial small head diameter of 70-100 mm, high-strength lightweight wood, the bulk of the end of the safety lever has a cramp cooling tower to increase the strength of the material at the point of impact. 9. outage frost protection equipment (1) cooling tower in the winter stops running, outdoor water pipes should be vented or circulating hot water into the communication device. (2) the sump and circulation ditch cooling tower should be warm in the freezing season cycle maintenance and inspection of cooling towers cooling tower protection measures are those projects in order to make your tower best performance, long life, good inspection and maintenance measures are essential. Under normal circumstances, respond to the tower every day to conduct a comprehensive observation, to ensure it is working properly. Need to check the part of a lot, we have set: 1, check and clean the stain waste (film, sprinkler system) 2, abnormal noise and vibration (fans, motors, pulleys, gear box, structure) 3. Check base position and bolt (fans, motors, pulleys, gear box) 4 and lubricants (motor, gear box belt) 5, check the water level (chassis) 6, check leakage (belt gearbox, chassis, float valve combination) 7 overall Check (fans, motors, pulleys, belts, gearboxes, chassis, float valve combination, film, sprinkler systems, structures, housing, escalators 8, tighten the bolts (fans, motors, pulleys, belts, gear box) 9, clean (fans, motors, pulleys, belts, gearboxes, chassis, float valve combination, film, sprinkler system) 10, check repainting (fans, motors, pulleys, belts, gear box) 11, check the seal (Belt gearbox) 12, under the safe use Replacement (fan, belt gearbox)
