Although the operation and maintenance of the excavator are relatively simple, the operation performance of your machine will be affected if you do not use and maintain the machine according to the correct operation and maintenance methods. It will even accelerate the wear of the machine and shorten the periodic maintenance cycle of the machine. The extensive application of second-hand excavators is now very high. As second-hand excavators are used less frequently in summer, they should be cleaned. The oil tank cleaning of the excavator is related to the quality of diesel oil. If the fuel tank is not clean, diesel may be mixed with many impurities, which will affect the quality of diesel, and eventually lead to engine damage. The methods for cleaning the oil tank include steam method, solvent method and purging method. This article will introduce the steps of purging method to clean the oil tank dirt. For reference only.
First, retain some diesel in the fuel tank. Then, the compressed air of 19.6~29.4KPa is introduced into the bottom of the oil tank with plastic pipes to make the diesel oil churn and clean. And constantly change the position and direction of the lower end of the gas pipe so that the entire oil tank can be cleaned. Drain the diesel oil from the oil tank immediately after purging. Make the impurities suspended in the oil flow out with the diesel oil. If the discharged diesel oil is dirty, clean it again with the same method until the discharged diesel oil contains no impurities.
