The Ingersoll Rand air compressor will not start, indicating a problem with the motor rotation direction (O_O)?
Thread Content
The Ingersoll Rand air compressor trips with an error indicating too low pressure before separation, and after restarting it shows an error asking to check the motor rotation direction? I need everyone’s help.
First, was there any movement of the electrical components after the machine stopped working? Could it be a wiring issue? Second, could the compressor have rotated in the reverse direction, or could there be a problem with the check valve on the outlet pipe, causing airflow to flow in the reverse direction and the compressor rotor to rotate backwards?~~
Which alarm indicates too low pressure before separation? Is there a vapor-liquid separator ahead? ~~
The motor fails to start at all, and then an alarm is displayed on the screen; check the motor’s rotation direction
It’s an alarm displayed on the screen; there is a vapor-liquid separator in front
Have the test results come in? Is it a failure of the outlet check valve that is causing the airflow to reverse? Also, what is the principle behind the component used to monitor the motor’s rotation direction, and has it been checked?
Ingersoll Rand’s machines are quite troublesome; they have a lot of self-protection features~~ The customer service is also rather rude~~ Hehe~~
We had an alarm indicating inertial motion; it could be turned on again after the high-voltage cabinet was reset
But the direction of the reversal is still correct~~ First, it needs to be reset; second, it’s necessary to wait until the reversal is complete (many compressor startup settings include a delay between two attempts to start)~~
As long as the motor does not start successfully within the specified time, an alarm will be triggered regarding the motor’s direction of rotation. I have encountered cases where such alarms were caused by faults in the solenoid coil, while low pressure before separation was due to the fact that the pressure in the unit had not been established yet
If the system cannot start properly within the specified time, a steering error alarm is triggered. The logic behind this is that once starting occurs, pressure should be established; if this does not happen, the direction should reverse. Therefore, it is not surprising to see a low pressure level before switching. I have encountered steering error alarms caused by faults in the solenoid coil
