In order to ensure the normal and stable operation of the screw air compressor,the operator of the air compressor should strictly follow the correct switch-on procedure.What are the precautions for the operation of the screw machine on and off? Let us tell you!

▶ Precautions before starting

1.Check the three-phase power supply and confirm that it is normal.

2.Open the door lock of the machine and observe the oil level of the air compressor.At this time,the oil level cannot be lower than the lowest level,otherwise the coolant needs to be added to the normal position.

3.Turn on the power of the controller and observe whether there is any abnormal display on the LCD screen."The equipment has been shut down" is displayed,indicating that it is normal.

4.Open the outlet valve of the air compressor.

5.After the above checks are correct,you can press the air compressor start button,and the air compressor can work normally.

▶ Notes for operation

1.After starting up,observe the air compressor running for 3 to 5 minutes.Observe whether there is abnormal sound and vibration,whether there is oil leakage,air leakage, etc., if there are any such phenomena,immediately stop the machine for inspection.

2.There is pressure in the moving pipeline and container.It is strictly forbidden to loosen the pipeline or plug,and open unnecessary valves.

3.Pay attention to the oil level during operation.When the machine is running,the oil level is lower than that after stopping,which is a normal phenomenon.When the oil level is not visible and the exhaust temperature reaches 100 degrees,the machine should be shut down immediately.Observe the oil level after stopping for 10 seconds.If the oil is insufficient,wait for the system to replenish the lubricating oil when there is no pressure in the system.

4.After the gas is cooled by the cooler,a certain amount of condensed water will be generated,which should be discharged regularly,otherwise the water will be carried into the rear system by the gas;according to the weather,the discharge time can be flexibly adjusted,and it is usually more frequent in summer.

5.During operation,record the voltage,current,outlet gas pressure,outlet exhaust temperature,oil level and other parameters every day for reference for future maintenance.

▶ Precautions for shutdown

1.Press the OFF button first,and the intelligent controller will stop according to the pre-programmed program after 10-15 seconds.The motor will stop.Avoid direct shutdown of the air compressor under heavy load.

2.When necessary,press the emergency stop switch to cut off the power supply of the main controller and contactor.

3.After the air compressor is stopped,it cannot be started immediately.You need to wait about 1 to 2 minutes for the system to automatically drain the internal pressure to prevent the motor from being damaged by the heavy load.

4.After the air compressor is debugged,adjust the pressure and other parameters according to the actual situation and set it to fully automatic control mode.Under normal circumstances,users do not need to adjust by themselves.
