Circular counter current fiberglass cooling tower

Overview of Circular Counterflow Fiberglass Cooling Tower Products

All cooling towers produced by the company are energy-saving because the installation capacity of the motor is relatively low compared to similar cooling towers at home and abroad. The water temperature drop of low-noise and ultra-low noise cooling towers is generally3-8℃, suitable for cooling general water temperature drops such as air conditioning.

The ultra-low noise cooling tower adopts a series of noise control measures on the basis of the low-noise cooling tower, and the standard point noise value is lower than the corresponding low-noise type5dB（A）. It is suitable for places with stricter noise requirements. For example, in places such as hotels, hospitals, public buildings, and residential areas, their basic piping, motor power, cooling water volume, and air volume are the same as those of corresponding low-noise cooling towers.

Industrial type, also known as medium high temperature cooling tower, generally has a water humidity drop of10～25℃, this type of tower has added a series of measures such as tower diameter, air volume, air pressure, power, and packing height. It is suitable for cooling industrial water with high temperature drop. The thermal performance of the industrial tower designed in this project is surplus, so please do not leave any room for selection. The code meaning is as follows:

Selection and use of circular counter current cooling tower

When selecting, it is necessary to know the amount of waterQInlet water temperaturet1, outlet water temperaturet2And design wet bulb temperaturet,Determine the model based on the thermodynamic performance curve. If it exceeds the curve, the requirements can be submitted to the Fourth Institute for research on the tower type by computer.

In terms of the cold resistance of the material, it can be applied to-50Regions with a temperature of ℃, but the average coldest month is lower than-10In areas with a temperature of ℃, anti icing measures should be requested when placing an order. Before leaving the factory, a sprinkler guide ring can be installed to prevent water from flowing onto the louvers.

The turbidity of the circulating water is not greater than50mg/Rising, not exceeding in the short term100mg/Sheng should not contain oil stains or mechanical impurities. If necessary, measures should be taken to eliminate algae and stabilize water quality.

The basic diagram is for reference during installation. The direction of the inlet and outlet pipes of the large tower is shown in the diagram. The water tower can be set at any horizontal position, but it must not touch the foundation. If there is a foundation in the middle, its load should be heavy during operation25%The rest75%The additional pressure caused by wind load should be considered on the roof, as it is evenly borne by the peripheral rectangular foundation.

less than125A type of cooling tower should have supports installed at the connection between the inlet and outlet pipes and the cooling tower to prevent excessive weight from pressing on the tower wall.

The water pipe is perforated according to the nominal flow rate. If the actual water volume differs from the nominal flow rate by ±15%Above, it is stated at the time of ordering that if the manufacturer changes the opening size, the water pressure of the tower's inlet pipe will be approximately2Mi to5The pressure should not be too high during design, otherwise excessive flow will cause water to float.

This product is suitable for water temperatures not exceeding60℃, if exceeded60℃, please specify when placing an order that our company can meet the requirements.

80Cooling tower fans of type and above can adjust the blade angle, but it is necessary to ensure that the blade angles are consistent and the current does not exceed the rated current of the motor. Various types of fans can be reversed for a short period of time to remove ice. Therefore, in areas with severe ice formation, reversible magnetic starters should be installed, and buttons should be installed near the cooling tower.<The method of adjusting the blades can be found in the description of the transverse flow fiberglass cooling tower>

When starting the cooling tower, be sure to turn on the water pump first, and then turn on the fan. It is not allowed to operate the fan without watering. Therefore, there is an inclined water collection plate on the water distribution pipe. If the fan is turned on without spraying water, the water distributor will reverse and the water collection plate will scrape the packing, causing it to be blown away by the wind or damaging the water distribution pipe. Therefore, when starting the cooling tower, the water pump must be turned on first, followed by the fan. When stopping the operation, the fan should be stopped first, followed by the water pump.

When users need to directly absorb water inside the cooling tower, they need to install "automatic water supply pipe", "rapid water supply pipe", "sewage pipe", which need to be specifically mentioned when ordering. The price list does not include this part of the price.
