In the huge system of the chemical industry, the engine is the core power source, and its stable and efficient performance is directly related to the smoothness of the entire production process. Inside the engine, the cylinder liner, as a key component, is like a layer of "invisible armor", silently guarding the stable operation of the engine and providing continuous power for chemical production.Chemical engine cylinder liner is a cylindrical part placed in the cylinder block hole of the engine body. It is pressed and fixed by the cylinder head. The piston reciprocates in its inner hole, and it is cooled by cooling water outside. Although it has a simple structure, it has many strict requirements.In terms of strength and rigidity, chemical engine cylinder liner must have sufficient strength. The chemical production environment is complex. The engine will be subjected to huge pressure and impact during operation. The cylinder liner needs to withstand the reciprocating impact of the piston and high temperature and high pressure to ensure that the engine can still operate stably under harsh working conditions. If the strength is insufficient, it is easy to deform or even break, causing engine failure and affecting the normal progress of chemical production.Wear resistance is also an important indicator of cylinder liner. When the chemical engine is working, there is frequent friction between the piston and the cylinder liner. If the wear resistance is poor, the cylinder liner will wear quickly, which will not only reduce the sealing performance of the engine, but also lead to problems such as increased oil consumption and reduced power. Therefore, the cylinder liner is generally made of wear-resistant alloy cast iron containing phosphorus or boron, such as HT25-47, HP-CuCrMo, etc., and some will also undergo surface treatments such as chrome plating, nitriding, and phosphating to improve its wear resistance.Good lubrication and cooling performance are also indispensable. The large amount of heat generated when the engine is working needs to be dissipated through the cooling system, and the cooling effect of the cylinder liner directly affects the temperature control of the engine. At the same time, good lubrication can reduce the friction between the piston and the cylinder liner, reduce wear, and extend the service life. If the lubrication is poor, it will cause dry friction between the cylinder liner and the piston, generate high temperature, accelerate wear, and even cause serious faults such as cylinder pulling.In addition, the chemical engine cylinder liner also needs to have reliable gas and water sealing performance to prevent gas and cooling water leakage and ensure the normal operation of the engine. Its inner surface should also have appropriate roughness, roundness and cylindricality accuracy, as well as a high position accuracy of the mounting support surface to the center of the inner hole to ensure the stability and sealing of the piston movement.Although the chemical engine cylinder liner is inconspicuous, it is an indispensable key component in chemical production. With its excellent performance, it protects the stable operation of chemical engines and contributes to the development of the chemical industry. In the future, with the continuous development of the chemical industry and the advancement of technology, cylinder liners will continue to innovate and upgrade to adapt to more stringent working conditions and continue to write their legend in the field of industrial power.
