Cooling tower fan
An ideal tower type, supplemented by a reasonable structure and advanced design of the air duct, can improve the uniformity of the tower air flow, reduce the tower air flow resistance, and ensure that the fan runs in the efficient working area. In this way, it has great social significance and high economic benefits for improving the cooling tower effect, reducing the cost and reducing the power consumption.
The MRT kinetic energy recovery type fiber reinforced plastic air duct is a new series of air duct updated and developed based on the design of the JBF energy-saving recovery air duct. The structure of the fan is reasonable and the design is advanced; it has the advantages of large amount of water treatment, good cooling effect and wide application range. It is an ideal fan for improving cooling effect, reducing cost and reducing power consumption.
There are 6 design models of MRT kinetic energy recovery glass fiber reinforced plastic fan:
MRT4.7, MRT6, MRT7.7, MRT8, MRT8.53, MRT9.14
Model description: (Take MRT4.7 as an example)
Design parameters (take MRT4.7 as an example)
30% of kinetic energy recovery maintains an air volume of 580,610,000 m3 / h
Water volume fluctuation range 500-1200T / h Water temperature difference 4-16 ℃
Suspended matter can be: 10-54PPM (short-term allowance is 100PPM) with a service life of more than 20-30 years

Installation, operation and maintenance precautions
First, the installation size of the air duct should be strict or close to φ4735 ± 5. And to ensure the overall sealing performance of the wind tube, including between the tube sheet and between the wind and the foundation. In order to reduce the kinetic energy recovery rate of the windshield
Second, pay attention to maintaining the sealing performance of the tower body and the air duct, the wall of the tower must not leak water or air, if there are leaks or gaps should be repaired in time.
Third, the connection between the air duct and the foundation requires the inner wall to be smooth and free of unevenness. Close holes and other door openings during operation.
