Why Log Book is important in Electric Screw Air Compressor?

Whenever you carried out any Maintaince in Screw Air Compressor,it must be note down in Log Book.This will help to all people who are concern with the

Machine.This will work as Record of the Compressor.

Prepare an Operational Diary and keep the Record of Periodical Inspection of Various Parts.This will help to find the Abnormality of the Air Compressor

Functioning prior to any Trouble.

In the Log Book,record the Discharge Pressure,Oil Pressure,Discharge Air Temperature,Incoming Voltage,Load and Unload Ampereage etc..,as well as

Operating Hours along with type of Servicing done and amount of Oil Replenished,which will become a precious record.

For your Reference,typical form of the Log Book is as below.

01)By keeping daily operation records,check the variation of Discharge Temperature.In case the Temperature differential between Atmospheric and

Discharge Air Temperature is gradually becoming greater,the cause may be,the soiled Oil Coler or sticked sludge.Clean the Oil Cooler in this case.

02)The reason for the Oil Filter Bowl to become tight is that much Sludge and Rust mixed in the Oil are sticking to the Oil Filter.In this case,Replace the

Oil and clean the oil Filter and Oil Cooler.

03)Take Sample of Lubricating Oil and Check for any abnormal smell.The Compressor Oil has basically no smell.Abnormal odour is due to deterioration

of the Oil with Oxidized Substance.Replace the Oil.If the Condition is extremely bad,an Overhaul of Air End may be required.

04)When the Sample of Oil is unclear and whitish in colour,water is mixed in.Replace the Oil and try to keep the Lubrication Oil constantly in good condition.

05)Check if the Oil is green in colour,if so,replace the oil.

06)As a rule,Oil should be replaced every 1500 working hours.However,replace totally when it is extremely dirty or it contains much of impurities even before

1500 working hours.

07)Take Oil Sample periodically.First sampling should be made at 250 working hours of start of the air Compressor and thereafter,every 500 working hours.

During summer or in tropical area,sampling should be made once a month or every 250 working hours of Operation.

You will find all this data,if you record it in Log Book.I hope,this information will help you to increase performance and life of Screw Air Compressor.
