Structure description
The series cooling fan is composed of a fan hood, fan motor, blade support frame, etc. The standard hood is made of steel plates stretched and formed by a hydraulic press, and the extended hood is made of steel plate rolls. The plates are welded to form. The air inlet is composed of the smallest holes. The fan motor adopts a special design method that sacrifices the level of protection. This series of fans has the characteristics of simple installation, low noise, low vibration and reliable operation.
The voltage and frequency used by the series fans
The rated frequency can be
the rated voltage is single phase.
Three are equal.
Environmental conditions for use
The altitude does not exceed meters. The ambient temperature is ℃℃
Air relative temperature ≦
Working mode protection level or.
Maintenance
The fan should be connected to an independent power supply, and variable frequency power supply cannot be used. After the fan is powered on, check whether the direction of rotation is consistent with the direction marked. The fan is packed in cartons and should be handled with care during transportation to avoid collisions and knocks. It should be transported strictly together with corrosive substances such as acids and alkalis. The fan should be stored in a clean and well-ventilated warehouse with an ambient temperature of ℃ and relative temperature, and the air should not contain corrosive gases.
