There is no resistance either in front of or behind the fan – will the motor burn out? !
Thread Content
The technician from the fan manufacturer told me. If there are no pipes at either the inlet or outlet of the fan, the resistance is zero; in this case, the current flowing through the fan’s motor becomes too high, causing the motor to burn out. Is this statement correct? It must be that both the front and back are under pressure for it to burn, right? Please give me some advice!
The pump can be damaged either by running idle or by having too much load; some fans may experience the same issue as well. Ordinary electric fans don’t have pipes connected at the front or back either; they can keep running without getting damaged no matter how they are used. Some fans may operate at a relatively high speed; if there are no restrictions on either the inlet or outlet, the air flow volume will be very high, which can lead to overloading and damage to the motor. By reducing the inlet size, the air flow volume can be kept within a reasonable range so that the fan can function properly. Vane vacuum pumps cannot pump air for long periods of time
Does “load” here refer to “current load”?
Low forward and backward resistance, high flow rate, overload.
Cold air has high density; before starting the fan, the inlet valve should be closed while the outlet valve should be fully opened
The traffic is too high, and the current is too high.
There is no resistance either in front of or behind the fan; the fan is under excessive load, which may cause the motor to burn out.
When the fan operates outside its flow range, it is prone to damaging the motor. Operating outside the pressure range can easily damage the fan. Therefore, both the flow rate and pressure must remain within the specified ranges for the fan and motor to operate properly
It is best for the fan not to exceed its flow rate, regardless of the level of resistance. If the flow rate exceeds the limit, it can easily cause the motor to burn out, or the motor may suffer significant wear and tear – it depends on your process design
