The quality stand or fall of oily fluid, whether to accord with a requirement, very big to the locomotive quality influence of equipment, to assure the normal movement of equipment, must ask strictly of of; of oily fluid quality (the viscosity that the working requirement that 1) books according to equipment chooses oily fluid reachs concerned function, contrast again the name that oily watch decides oil and affirmatory and concrete shop sign. (Before 2) is installed, should do 2 times to housing, pipeline clean, use for the first time of 20% vitriolic or hydrochloric acid cleans 30 ～ 40min, counteract 15min with the mineral of 10% next, clean with warm water finally, dry and oiled hind install in order to have, pass after cleaning, remaining metal pink is not gotten in housing, pipeline not, rust, sealed material, silk thread, paint and coating. (After 3) has been installed, undertake to hydraulic pressure system interior is cleaned, clean use oil of hydraulic pressure job or test-drive oil, the temperature when cleaning is in 80 ℃ of 50 ～ , begin to want clearance movement, run for long next 4 ～ 12h, when cleaning, lube filter oily machine is installed on loop, clean lube filter till oily machine has foreign matter no longer. (When 4) discovers to there is mechanical foreign matter in oily fluid, should instantly oil change is cleaned. Usually, should inspect oily breed, the metabolic circumstance of the temperature in working process and pressure, filter measure and precision, the particular case such as working environment is affirmatory, work in its change inside limits of 4000 ～ 8000h, but 2000h does not exceed at most after be being cheered for the first time, answer to change entirely. (5) should prevent oily fluid to get in working process environmental pollution, because the blowhole of this gasoline tank wants to install efficient filter, prevent dirt to invade, the oily juice that buys newly wants the quiet day that put number, adopt system of hydraulic pressure of infuse of lube filter oily machine or lubricant system next, want to often be checked to seal unit, change regularly. When use oil is tasted, want to accomplish correctly choice oil to taste only, undertake oil is tasted reasonably change, strengthen the management that lubricant equipment works at the same time, can get apparent energy-saving effect and considerable economic benefits.
