Defensive Measures and Starting Methods for High-Temperature Fire-Rated Axial Fans
Depending on operating conditions, the bearings of high-temperature fire-rated axial fans may require grease replenishment or replacement (motor-mounted bearings need not be replaced within their service life).
To ensure adequate lubrication during operation, grease replenishment must occur at intervals of no more than 1000 hours. Both inner and outer bearing races must be filled with lithium-based grease.
Dry-running is strictly prohibited. To prevent motor moisture ingress, axial fans must be stored in dry conditions.
Outdoor high-temperature fire-rated axial fans require protective measures. To prevent fan damage, avoid impacts during storage and transportation.
Low noise, economical pricing, extended service life, robust construction, high stability, and versatile applications. Notable advantages include superior performance metrics—airflow, pressure, and noise levels—compared to comparable products on the market.
This series of high-temperature fire-rated axial fans offers explosion-proof, corrosion-resistant, and single-phase variants to meet diverse user requirements.
Operation of the high-temperature fire-rated axial fan is driven by a motor. Fundamentally, all machinery shares this common requirement for an "engine" during execution.
When selecting motors for high-temperature fire-fighting axial fans, it is typically expected that the motor will rapidly drive the propeller to its rated speed and maintain normal operation.
Motor start-up involves the start-up power supply and the acceleration process. Start-up modes are categorised as full-voltage start-up and reduced-voltage start-up.
To rationally select the motor start-up mode, specific analysis must be conducted based on the capacity of the power supply network, the start-up torque requirements of the mechanical load, and the characteristics of the motor itself. This analysis determines the specified start-up method.
For instance, where the power grid capacity is substantial and the motor's starting current will not cause significant voltage drops in the grid, and where the grid's control lines and machinery can briefly handle sufficiently large starting currents, full-voltage starting may be employed.
When the torque required by the fan during start-up is not excessive, and the grid capacity is comparable to the motor's requirements, the primary consideration becomes minimising the starting current, necessitating reduced-voltage starting.
