The development of piston for defoamer
After extensive market research and according to the actual needs of different manufacturers, Shantui Komatsu Lubricating Oil Company has developed a new type of cleaning agent based on the original metal cleaning agent. This product is mainly composed of high-quality surfactants, combined with a variety of inorganic additives, and scientifically formulated through special processes. It has the advantages of strong degreasing and decontamination capabilities and easy rinsing. It can replace organic solvents such as gasoline, kerosene, diesel, trichloroethylene, and carbon tetrachloride, and is used as a defoaming agent to clean oil, butter, and carbon deposits on metal bodies and parts. This product is non-toxic, harmless, non-explosive, non-burning, and easy to use. Various types of engines generate more or less carbon deposits during operation due to the influence of relevant factors. Carbon deposits are products formed by fuel or lubricating oil under the action of high temperature and oxygen. When the engine is working, the fuel or the lubricating oil that enters the combustion chamber cannot be 100% burned. Under the catalytic action of high temperature and oxygen, the unburned part of the oil forms hydroxy acid and resinous colloid, which adheres to the surface of the parts and further shrinks into a complex mixture of asphaltene and oil coke through high temperature, which is the so-called carbon deposit. Carbon deposits in the cylinder head will reduce the cooling effect of the engine. Since the thermal conductivity of carbon deposits is extremely poor, its thermal conductivity coefficient is only one-fiftieth of that of cast iron or steel, which will cause the engine to overheat and greatly reduce the power and economy of the engine. Carbon deposits on the top of the piston will form many hot surfaces, causing premature combustion and deflagration, detonation, knocking and abnormal wear, shortening the service life of the engine. Carbon deposits on the working surface of the valve and its seat ring will cause the valve to close loosely and leak, resulting in undesirable phenomena such as difficulty in starting the engine, inability to work, and easy ablation of the valve. Carbon deposits and glue on the valve guide and valve stem will accelerate the wear of the valve stem and valve guide, and even cause the valve stem to move awkwardly and get stuck in the valve guide. Carbon deposits in the piston ring groove will reduce the side clearance and back clearance of the piston ring, or even eliminate them. The end clearance is affected by carbon deposits and has no shrinkage clearance. At this time, it is very easy to cause the piston ring to lose elasticity, the cylinder to be loosely sealed, and even break the piston ring and pull the cylinder. Carbon deposits on the fuel injector can easily get the injector stuck, causing the engine to run without a cylinder or suddenly flame out. Carbon deposits on the starting spray hole of the pre-combustion chamber will block the spray hole and make it difficult to start the engine. Too much carbon deposits on the spark plug, when the fuel is wet, is equivalent to a parallel shunt resistor between the spark plug electrodes, causing the spark plug to leak electricity and the spark is too weak. In severe cases, the spark plug cannot work.
