How to distinguish the quality of screw air compressor?

We can distinguish through the following methods:

1. Set the operation mode of the screw compressor to automatic mode. When the dryer supplies air to the air storage tank normally, observe the pressure value displayed on the control panel of the screw compressor and the increase of the air pressure value of the air storage tank. . When the screw compressor is unloading, observe whether the pressure value displayed on the control panel is consistent with the pressure upper limit setting value.

2. When the exhaust valve of the compressed air system is closed, pay attention to the drop rate of the air pressure in the system to see if there is any air leakage in the system. Keep the system compressed air pressure at the lower limit, and observe whether the time interval from the unloading of the screw compressor to the shutdown of the motor is consistent with the set time.

3. Let the cut-off valve under the air storage tank vent to the air, and observe the pressure value displayed on the control panel of the screw compressor and the drop of the air pressure value of the air storage tank. When the screw compressor restarts the load, observe whether the pressure value displayed on the control panel is consistent with the set value.

4. During the process of boosting and reducing the pressure of the machine, pay attention to whether the temperature value of the ventilation fan of the screw compressor is consistent with the set value when it is started and stopped.

5. When the power is turned on, use the operation setting value menu program to change the adopted automatic control mode to continuous control mode. After the program starts, the control mode should be changed to continuous control mode. After setting the operation mode of the screw compressor to the continuous mode, take the same content as the automatic mode to test the screw compressor, and pay attention to whether the drive motor is automatically shut down after the screw compressor is idle for a certain period of time, and when the compressed air main pipe Whether the machine can be started at any time within the set pressure range.
