Raptors, the authorized dealer of Cummins (China), established in 2015 by Mr. Jordan Wang who worked in Cummins for 8 years. Raptors do: Cummins, filters, turbocharger, and construction machinery parts from China. We have big advantages for almost all genuine Cummins generators, engine assembly and spare parts, especially for NTA855, KTA19, KTA38, KTA50, QSK60, QSX15 etc...Application of oil coolerOil coolers can be divided into air-cooled oil coolers and water-cooled oil coolers according to different heat exchange media, mainly used to cool hydraulic oil and lubricating oil; oil coolers are widely used in plastic machinery, construction machinery, mining machinery, Automobile, steel, wind power, aerospace and other industries.FunctionHydraulic system and lubricating system are important components of each mechanical equipment. The hydraulic system needs to maintain high pressure continuously when working, which will generate a lot of heat, and the oil temperature will rise after a long time of work. If the heat is not dissipated in time, the sealing components of the system will be aged and damaged, and the viscosity of the oil will decrease as the oil temperature increases, and the oil pressure will not meet the working requirements. In order to ensure the safe and reliable operation of the unit. The oil temperature must be controlled within the specified range. Although the main reason for the increase in oil temperature of the lubrication system is different from that of the hydraulic system, it is also necessary to control the oil temperature within the specified range.
