High-Temperature Application Site
In mid-June 2014, a wastewater treatment plant in Jiaxing, Zhejiang Province, invited our company to participate in its effluent quality upgrade project and reported that several brands of blowers—some of which were even imported from overseas—that had previously operated normally at the site had been frequently damaged by overheating and burnout following the upgrade.
Our company’s technical team conducted a detailed on-site investigation and found that the water tank at the facility had been raised by 3 meters. To prevent an increase in the fan motor power—since such an increase would necessitate the replacement of the entire on-site control cabinet, variable-frequency drive, and motor—we adopted a solution of reducing the fan frequency to 15 Hz and operating the three fans in parallel. Although the motor current remained within normal limits after this adjustment, the fan itself experienced excessively high body temperatures due to operation at high pressure and low frequency, ultimately leading to bearing failure. Subsequently, our technicians leveraged the HT series’ unique dual air–water cooling design, which facilitates easy retrofitting for high-temperature, high-pressure applications, to convert the existing on-site fans to water-cooled operation. This ensured stable fan performance and earned high praise from the customer.
(As shown in the figure) After modification, the fan operates normally at a high ambient temperature of 175°C.
