The role of the cooling tower
Release date：2014/10/30
Cooling tower fan is the core of the circulating water system, the water circulation device management situation, no matter from which side the amount of equipment, maintenance work, in terms of power consumption, etc., cooling tower fans have occupied a large proportion. Fan units accounted for 57% of total workshop equipment, accounting for 60% of the total maintenance man, power consumption accounts for 22% of the total. How to ensure the long-cycle operation of the device in saving energy, reducing labor situation down, following a brief talk about measures:
1, the cross-flow cooling tower should be controlled to the lower edge of the upper packing fan suction segment height is equal to or greater than 0.2 times the fan diameter.
2, counterflow cooling tower fill the top surface to a height of between airflow duct import contraction section shall comply with the following provisions:
1) When the cover is flat-topped tower, the top surface of the packing date from the airflow constriction apex angle should be less than 90 °; when provided diversion ring (umbrella) under the flat top cover when the water heater from the top to close surface flow constriction counting vertex can be 90 ° ~ 110 °.
2) When the water tower is more than self-closing lid for contraction type, contraction section cover corners should adopt the 90 ° ~ 110 °.
3, the cross-flow cooling tower water spray filler from the top to the bottom of the tower due to the contraction of the vertical inclination of the axis. Drenching shrink packing trickle inclination appropriate for the 9 ° ~ 11 °; membrane-type water spray filler contraction inclination appropriate for the 5 ° ~ 6 °.
4, bilateral air intake counterflow cooling tower should be located in central wind baffle, the baffle packing support beam bottom margin from 200 ~ 300mm, extending into the lower edge of the tower sump below the surface.
5, cross-flow cooling tower should set measures the air from the bottom to the surface between the filler to prevent short-circuit circulation.
