During operation, it actively performs inspections while in use. The product runs pre-edited programs internally, which operate proactively. At the same time, data collection and display tasks are also automated, enabling the product to perform self-maintenance.

Informationization emerges. The product operates with a multitude of parameters, which can be displayed, such as the fire fan's rotational speed and cooling temperature. Additionally, it can also show the operational status and maintenance for low pressure, low speed, and more.

The high-temperature exhaust fan is primarily composed of components such as the impeller, housing, inlet collector, guide vanes, and motor. The impeller features 6 curved blades with meridional acceleration characteristics, which are welded to the housing. After dynamic balance and overspeed inspections, it boasts excellent aerodynamic performance. The high-temperature exhaust fan can be used for both high-temperature exhaust and ventilation air exchange. Its operating conditions are as follows.

Ensure to inspect and replace gaskets and sealing materials between all joints of the high-temperature exhaust fan. The manufacturer of high-temperature exhaust fans in Hebei can manually start the unit to check the indicator lights, as well as the ammeter and voltmeter, to confirm their normal operation. Additionally, they should verify if there are any unusual noises from the fan's components and whether the three-phase AC current values are balanced.

Some plans directly confirm values as specified by standards, often resulting in the selected fans having insufficient air volume and pressure to meet requirements; others opt for a combined ventilation and mechanical smoke exhaust system, but fail to use dual-speed fans as planned during construction; some construction units do not order fans according to the planned model, purchasing those with lower power standards, leading to severely inadequate air volume of the fans.
