The counterflow glass cooling tower is an energy-saving new product designed by the Fourth Design Institute of the Ministry of Machinery Industry. This product applies the energy-saving fiberglass cooling tower patent obtained by the Fourth Institute. In particular, the cooling tower fan is equipped with a variable torque off-pole two-speed motor. When the temperature is low (such as at night), the motor runs at low speed and the cooling tower noise can be reduced. In addition, using two-speed motors saves significant energy. According to calculations, when multiple cooling towers are equipped with single-speed motors, although some of the motors can be stopped when the air wet-bulb humidity is low to save energy, it still consumes more power (in years) than using two-speed motors. ). This product also uses the oblique trapezoidal wave filler sheets for square counter-flow cooling towers that were nationally patented by the Fourth Institute. Tested by Beijing Academy of Water Sciences and Foshan Real Tower, its thermal and resistance characteristics are better than other fillers.
Square counterflow cooling towers have three series, nine models, and ninety products:

Design parameters
The industrial tower is: air wet bulb temperature ℃, cooling tower temperature Drop: ~℃.
Civil tower is: air wet bulb temperature ℃, cooling tower temperature drop: ~ ℃.
When selecting a tower, you need to know the cooling water volume, the water temperature entering the tower, the water temperature leaving the tower, and the wet bulb temperature of the air.
The material of the cooling tower can withstand low temperatures of -℃, but when ordering in areas where the average temperature of the coldest month is lower than -℃, it should be stated so that anti-icing measures can be taken.
The turbidity of circulating water should not be greater than mg/L, and should not be greater than mg/L in the short term. It should not contain oil stains and mechanical impurities. Measures to eliminate algae and stabilize water quality should be taken when necessary.
The direction of the inlet and outlet pipes of the cooling tower can be rotated according to, and.
The water distribution system is designed according to the nominal water flow. If the actual water volume differs from the nominal water volume by more than the above, it should be stated when ordering so that some data can be modified.
The inlet water temperature of the cooling tower shall not exceed ℃. If it exceeds ℃, it should be stated when ordering.
The installation angle of the fan blades is adjustable, but the angle must be kept consistent. And the current of the motor does not exceed the rated current of the motor.
The fan can be reversed at low speed for a short period of time to eliminate ice.
When using the water pan of the cooling tower as a pool, additional automatic water supply pipes, rapid water supply pipes, sewage pipes, and overflow pipes must be installed. This must be specifically mentioned when ordering, and the cost will be charged separately.
, motors and fans are all supplied in complete sets, and the factory needs to send employees to the site for installation or technical guidance.
Fiberglass cooling tower structure:
Filling: It adopts the oblique trapezoidal wave filler sheet patented by the Fourth Institute, with convex ribs added laterally. It has large water redistribution ability, small resistance, good thermal performance, and high temperature resistance. Resistant to low temperature - ℃, good flame retardancy.
Motor: Designed by the Department of Electrical Engineering of Tsinghua University and manufactured by the Yingmengjin Motor Factory, the patented product of the Fourth Institute is a variable torque variable extremely low-noise energy-saving motor. It has good sealing and waterproof performance, high temperature resistance, high efficiency and low noise.
Deceleration device: The deceleration device with a power of /. adopts polyester fiber reinforced neoprene power belt transmission, which is high temperature resistant, high efficiency, does not stretch when exposed to water, overcomes the slipping phenomenon, and makes very little noise. The power reduction device adopts gear reduction method, and the motor is installed outside the hair dryer.
Fan: Low-noise, high-efficiency, airfoil-shaped fiberglass blades designed by the Department of Engineering Mechanics of Tsinghua University based on the parameters of this series of products. They have low noise, high efficiency, and adjustable blade angles.
Water collection and water distribution device: Use reflective low-pressure nozzles. For small towers, single swirl nozzles are used to achieve uniform water distribution and low water pressure. The water collecting device can reduce the loss of floating water to... Sound-absorbing facilities: The ultra-low-noise cooling tower is equipped with a shield and sound-absorbing grille with sound-absorbing materials on the air outlet of the upper tower body to achieve the maximum noise reduction effect. (
) Sound-absorbing facilities: The ultra-low-noise cooling tower is equipped with a shield and sound-absorbing grille with sound-absorbing materials on the air outlet of the upper tower body to reduce the noise of the fan and motor. For small towers, mushroom-shaped sound-absorbing grilles are installed.
Dripping noise reduction pad: For low-noise and ultra-low-noise cooling towers, specially designed sound-absorbing pads with good water permeability are equipped with a layer of ramp plates underneath, which greatly reduces dripping noise.
Inspection platform: The checkered steel plate inspection platform on the top of the tower is convenient for maintenance and installation.
Lower tray: Cooling towers with shallow water trays and deep water trays are equipped with lower trays for water storage. According to ordering requirements, it can be equipped with overflow, sewage, automatic and manual water supply pipes, and can directly absorb water from the lower tray.
Bracket: Cooling tower steel bracket, galvanized and coated with epoxy asphalt paint to prevent corrosion, and fasteners are galvanized bolts.
