Through the analysis of the principle of the existing methods for determination the water content in oil and the components of gear oil

as well as monitoring needs of water content in gear oil

it is found that the existing methods can not accurately and quickly detect the water content in gear oil. the new gear oil and running gear oil for wind power was selected as experiment object

through study of selection of test conditions and the accuracy of the results

it is found a method that can accurately and quickly detect the water content in the gear oil.This method is a combination of the Karl Fischer coulometry water analyzer and the heating furnace. With compressed nitrogen or air as the carrier gas

after the carrier gas is dried through the molecular sieve

it cross the sealed test bottle containing 1g oil sample and 1mL n-heptane by the sleeve air needle

Heat the bottle at 150 ℃

and transfer the water in the oil sample to enter the Karl Fischer water analyzer for detection.
