The engine uses water that is not completely softened, and scale is formed in the cooling system. Scale is not easy to heat transfer, accumulation of more, it will cause the engine to overheat; uneven accumulation, will cause mechanical crack due to uneven heat transfer. Therefore, the amount of scale deposits in the cooling system should be considered, or the scale should be cleaned every 500 to 1500 h of the engine cycle. The following describes two cleaning methods. 1, let go of the cooling water, add 25? hydrochloric acid solution, park for 10min, the scale will fall off, dissolve, release the cleaning solution, and then rinse with water. Sometimes the released cleaning liquid is mixed with a scale block to block the drain valve. At this time, the water pipe below can be directly removed to release the cleaning solution. The cleaning solution is corrosive and care must be taken not to splash on the skin or clothing. In case of splashing, rinse immediately with clean water. Note that when preparing an aqueous solution of hydrochloric acid, the hydrochloric acid should be slowly poured into water, and can be used after mixing. Do not pour water into hydrochloric acid. 2. Drain the cooling water and inject a mixture of 6 hot water, 0.5% caustic soda (caustic soda) and 0.1? kerosene into the water tank, let stand for 2 hours, and run the engine for 10 minutes. This interval runs 5 to 6 times or the engine load is continuous. After 10 to 12 hours of operation, the cleaning fluid was released. After the engine is slightly cold, clean the water tank and water channel with clean water. If it is found that the scale has not been removed, use the method described above and clean it again.
Oxygen Cylinder Filling System
With PSA principles, ETR Oxygen Cylinder Filling system can produce 93%±3% purity oxygen gas from compressed air directly. ETR oxygen cylinder filling system is consisted of Atlas screw air compressor, refrigerated air dryer, compressed air filter, air buffer tank, ETR Oxygen Plant, oxygen buffer tank, oxygen booster, cylinder filling station and HMI control cabinet.
Compressed air is purified through the air dryer and filters to a certain level for main plant to work with. Air buffer is incorporated for smooth supply of compressed air thus to reduce fluctuation of compressed air source. The plant produces oxygen with PSA (pressure swing adsorption) technology, which is a time proven oxygen generation method. Oxygen of desired purity at 93%±3% is delivered to oxygen buffer tank for smooth supply of product gas. Oxygen in buffer tank is maintained at 4bar pressure. With an oxygen booster, the oxygen pressure can be to 150bar and fill in cylinders.
