Axial Fan The Flexibility

Jun 16, 2017

1. After the installation of the fan, Axial Fan before starting the fan should check the flexibility of rotation, hand toggle the blade is jamming phenomenon. Check whether there are any tools and other debris in the fan and adjacent pipes.

2. Check that the damper in the pipe is open.

3, personnel should be away from the fan.

4, the point of the fan, Axial Fan to see whether the fan steering with the rotation mark, after passing the test, the test run after 10-30 minutes to stop, check the leaves with or without loose phenomenon, vibration and the base of the coupling bolts loose, all normal, Was officially launched, put into operation.

Fan in the normal operation, Axial Fan the main monitoring motor current, current is not only a sign of fan load, but also some abnormal accident forecast. Second, we must always check the motor and fan vibration is normal and whether the friction, abnormal sound. The parallel operation of the fan should pay attention to monitor whether the fan is running in the case of surge state.

In normal operation, in case of the following circumstances should immediately stop inspection:

1, the fan has a strong vibration or rubbing sound.

2, the motor current suddenly rises and exceeds the rated current of the motor.

3, the motor bearing temperature rose sharply.

1, without fault operation, only in the case of complete normal fan equipment can run.

2, regularly check the fan blade is loose, Axial Fan leaves and the balloon clearance is normal.

3, regularly check the motor and chassis connection bolt fastening, check the vibration seat and the base connection is intact.

4, regular removal of leaf surface dust, dirt.

5, regular replacement of grease for the motor bearings, usually three months plus an oil, but also according to the actual situation to change the grease.

When the axial fan is started, the motor current will be 5-6 times higher than the rated value, which will not only affect the service life of the motor but also consume more power. Axial Fan The system will leave a certain margin in the design of the motor , The speed of the motor is fixed, but in the actual use of the process, sometimes to lower or higher speed operation, so the frequency conversion is very necessary. Inverter can achieve the motor soft start, by changing the device input voltage frequency to achieve the purpose of energy saving, Axial Fan but also to provide equipment over-current, overvoltage, overload and other protection.
