(1) Purifying the method.
That is, some diesel is retained in the tank, and then 19.6 ~ 29.4 kPa compressed air is passed through the plastic tube into the bottom of the fuel tank, and the diesel is turning, and the position and direction of the lower end of the trachea are continuously cleaned to clean the entire fuel tank.
After purging, the diesel of the fuel tank was immediately discharged, and the Carter excavator repaired the impurities suspended in the oil flow out with diesel. If the diesel flowing is dirty, the method is cleaned again until the released oil does not contain impurities.
(2) Vapor method.
Return the diesel, remove the fuel tank, then add a large half of the water to the diesel tank, and introduce the vapor catheter into the water, so that the water in the diesel is about left. Thus, the glue and residual diesel molecules adhering to the inner wall of the box can be dissolved in water.
Light dirt is floating in the water and washed away. This is twice in turn, the diesel is rinsed.
(3) Solvent method.
Clean the Carter excavator diesel tank with hot water, and then dried with compressed air to remove the diesel vapor therebetween, and finally put the diesel tank into aqueous solution containing 10% sodium hydroxide. After immersing, rinse the interior and exterior of the diesel tank with water. If there is rust outside, brush it with a steel wire.
Clearance of cooling dirt in Hyundai excavator maintenance
The 15% sodium hydroxide solution was injected into the system. After 8 to 12 h, the diesel engine was operated. When the water temperature rose to 80 to 90'c, stop, immediately released the lotion, to prevent the scale of scale in the solution, and then used Wash the water cleaning system until it is washed.
If the Carterpillar excavator cylinder head is an aluminum alloy structure, it can be used in a ratio of 50 g of sodium silicate, a proportion of liquid soap, 10 kg of water, and a Carterpillar excavator repair and repair, in the cooling system, running at the working temperature of the Carterpillar excavator LH Left and right, then discharge the lotion, then use water to wash.
