How to deal with the failure of air suspension blower in use?

When the air suspension blower fails, it can be handled according to the following steps:

First, the fault preliminary judgment

Observe the operation status indicator and alarm information.

Modern air suspension blowers are usually equipped with a control panel with various operating status indicators. When a fault occurs, the indicator light will flash or change color, indicating the fault type. For example, if the power indicator goes out, it may indicate that there is a problem with the power supply, while if the over-temperature indicator goes on, it may indicate that the internal temperature of the machine is abnormal.

At the same time, pay attention to the alarm information displayed on the control panel. These alarm messages may be simple codes, and you need to consult the equipment manual to determine the specific cause of the failure. For example, "E-001" may represent motor failure, "E-002" may represent sensor abnormality, etc.

Listen to the sound of equipment running.

The sound of air suspension blower in normal operation is stable and regular. If you hear abnormal noise, such as sharp friction sound, impact sound or irregular vibration sound, it may be that the bearing is damaged, the impeller is unbalanced or foreign objects enter the fan. For example, when the bearing is worn, it will emit a continuous "buzzing" sound, and the collision between the impeller and the shell will produce a crisp impact sound.

Check the status of air outlet and air inlet.

Check whether the air volume and pressure at the air outlet are normal. If the air volume is obviously reduced or the pressure is unstable, it may be that the impeller inside the fan is blocked, the pipeline leaks or the air filter is blocked. Check whether the air inlet is blocked by foreign objects and whether the air filter is clean, because the blocked filter will limit the air entry and lead to the performance degradation of the fan.

Second, the common faults and treatment methods

power problem

Fault symptom: the fan can't start, and the power indicator light doesn't light up.

Solution: First, check whether the power plug is plugged in and whether the socket has electricity. You can use an electric pen or multimeter to check whether the socket voltage is normal. If the power supply is normal, check whether the fuse inside the fan is blown. If the fuse is blown, replace the fuse with the same specification, but pay attention to find out the cause of the fuse, which may be short circuit or overload.

Motor failure

Fault symptom: the motor is not running or abnormal, which may be accompanied by burning smell, and the motor fault indicator light is on.

Solution: Stop the operation of the fan immediately to avoid further damage. Check whether the wiring of the motor is loose or disconnected, and reconnect it firmly. If the motor is overheated, it may be due to excessive load or poor heat dissipation. After waiting for the motor to cool down, check whether the impeller of the fan is stuck, clean up foreign matter or adjust the position of the impeller. If the motor is seriously damaged, such as winding burning, it needs to be replaced.

Overheat fault

Fault symptom: the indicator light is on when the temperature is too high, and the fan may stop running automatically.

Solution: Check the cooling system of the fan. Air suspension blower usually dissipates heat by air cooling or water cooling. If it is air-cooled, check whether the cooling fan is operating normally and whether the vent is blocked. Clean up the sundries around the vents to ensure smooth air circulation. If it is water-cooled, check whether the cooling water pipeline is leaking, blocked or the water temperature is too high, check whether the cooling water pump works normally, and repair or replace the damaged parts.

Impeller failure

Fault phenomenon: the vibration of the fan is intensified during operation, with abnormal noise and unstable air volume and pressure.

Solution: Stop the operation of the fan and open the fan housing to check the impeller. If there are foreign objects on the impeller, clean them carefully. If the impeller is damaged or unbalanced, it needs to be repaired or replaced. Impeller imbalance may be caused by long-term operation wear, corrosion or incorrect calibration during installation. Professional impeller balancing equipment can be used to check and adjust the impeller balance.

Sensor failure

Fault phenomenon: the fault indicator light related to the sensor lights up, and the operating parameters of the fan (such as speed, temperature, pressure, etc.) are abnormal.

Solution: First, check whether the wiring of the sensor is loose or damaged. Reconnect or replace the damaged connecting cable. If the sensor itself is damaged, it needs to be replaced with a sensor of the same model. After replacing the sensor, it may be necessary to recalibrate the control system of the fan to ensure that the sensor can accurately monitor and feed back the operating parameters.

Third, the inspection and testing after troubleshooting

Component installation inspection

After troubleshooting and reinstalling or replacing components, carefully check whether all components are installed securely. Check whether the fan casing is well sealed, whether the screws are tightened and whether the pipes are tightly connected to avoid leakage.

Running test

Restart the fan for no-load operation test. Observe whether the start-up process of the fan is smooth, whether the running sound is normal, and whether the indicator lights show normal status. Then load it gradually to check whether the performance of the fan under different loads, such as air volume, pressure, temperature and other parameters meet the technical specifications of the equipment. During the operation test, keep observing for a period of time to ensure that the fault has been completely eliminated and the fan can run stably.

Record the failure and treatment.

Record the fault phenomenon, treatment process and results of the fan in detail. This is very helpful for future equipment maintenance, fault prevention and warranty. The recorded contents may include information such as the time when the fault occurred, the fault code, the inspection and handling steps, and the replaced parts.
