• Fan with advantages of being small volume, lightweight, angle adjustable, and convenient for installation and maintenance.
• Transportation gas temperature at -20℃ ~ 300℃.
• The fan performance is tested by airway or AMCA both available, and the fan performance data is true and reliable.
• Fan Material is optional according to your need.
• Customizable

Description:

The centrifugal fan is based on the principle of converting kinetic energy into potential energy, using a high-speed rotating impeller to accelerate the gas, and then decelerating and changing the flow direction to convert the kinetic energy into potential energy. In a single-stage centrifugal fan, the gas enters the impeller from the axial direction, the gas changes to the radial direction as it flows through the impeller, and then enters the diffuser. In the diffuser, the gas changes the direction of flow and the increase in the cross-sectional area of the duct slows down the gas flow, which converts kinetic energy into pressure energy. The pressure increase occurs mainly in the impeller, and secondly in the diffusion process. In a multi-stage centrifugal fan, a recirculation is used to move the airflow to the next impeller, creating higher pressure.

Precautions

• The centrifugal fan suddenly vibrated strongly and exceeded the trip value.
• There are scratches or abnormal friction sounds inside the body.
• There is smoke from any bearing or seal, or the temperature of a bearing rises sharply to the alarm value.
• When the oil pressure is lower than the alarm value and cannot return to normal.
• The oil tank level is low, and there is a phenomenon of suction.
• The shaft displacement value shows an obvious and continuous increase, when the alarm value is reached.
• Normal shutdown: The normal shutdown of the unit is performed according to the following procedures.
• Gradually open the vent valve (or outlet bypass valve) while gradually closing the exhaust valve.
• Gradually close the intake throttle to 20-25°.
• Press the stop button and pay attention to whether there is any abnormal phenomenon during the shutdown.
• The oil supply can be stopped after the unit stops for 5 to 10 minutes, or when the bearing temperature drops below 45°C. For units with floating ring seals, the seal oil pump must continue to supply oil until the body temperature is lower than 80°C.

Applications:

• For building ventilation systems, air-conditioning(HVAC), purification equipment, and a High-temperature system.
• For equipment or system of filtration & drying, fume hood & spray booth, painting room, food processing, kitchen room, and so on.
