Air compressor oil uses

Air compressor oil uses

The movement of screw is pineaple-sharpened, therefore it's nescessary to use lubricating oil with theaim to reduce the corrosion and softly operate. The bearing is completely stay in air end so it is also lubricated with air compressor oil.

Compressors equipment maintenance

Each compressor requires well-timed service. Under the service means change the oil, replacement of the oil and air filter, separator, check the belt tension (if it is not the compressor with direct drive), lubrication of the bearings, different type of the valve checking, replacement of the valves if necessary. Also according to the operational manual it is necessary to replace inlet valve repairing kit, minimum pressure valve, thermostat valve and return valve.

Maintenance of Handsome II air compressor

Compressed air system in factory plays an important role. In order to ensure the stable operation during the manufacturing process, the regulary maintenance is nescessary . However, there are many different problems in fact such as: Air compressors, dusty air dryers, high engine room temperatures, unsecured wind convection ... lead to reduce using time of compressor accessories (air filter, oil filter, oil separator ...). On the other hand, the recommended maintenance in some factories is not seriously followed and there are deviations.

Troubleshooting of Handsome II

Step 1: Check the condition of the LED lamps and find out the cause of      emergency shutdown by refering to the table below:

RUNNING lamp FAULT
  lamp
Fault detected 

Operation of air compressor

OFF  ON

Compressor motor overcurrent or motor coil high temperature.

Emergency shutdown.
OFF Blinking
(1.2 sec./cycle)
Discharge temperature higher than 110ºC(230ºF) or sensor short circuit.
OFF High pitched blinking.
(0,4 sec./cycle)
Sensor failure or poor connector contact.
BLINKING  ON  Dryer failure. Emergency shutdown unless the conditiuous operation is selected.


  Step 2: Eliminate  the cause of the fault.
  Step 3: Press the START button (green) to restart and the FAULT lamp will go  out.
  Caution:

  • The dryer safety machanism is activated when the START and STOP buttons are pressed frequently.
  • Keep 3 minute interval between stop and restart.
  • Countermeasure for motor overcurrent/ motor coil high temperature.

                                                                                            Meter panel:

LED lamps on the meter panel Reset
Power  Running Fault Reset thermal relay
  1.  When excessive curent passed in the motor, the thermal switch trips and the compressor shuts down. Remove the cause of overcurrent and press the thermal relay reset (blue) button. The lamp will go out when the START button (green) is pressed to restart.
  1. Reduced  cooling air volume for the motor may increase motor temperature, activating the motor protector and stopping the compressor. Eliminate the cause, i.e clogged dust filter or the like. Press the START button ( green) to restart, and the FAULT lamp will go out.

When the motor of Handsome II does not starts.

Step 1:  Turn off the earth leakage breaker.
Step 2:  Interchange two of the three phases in the power unit and connect again.
 Step 3:  Return the breaker on and see if the motor starts.
