Introduction to Hydraulic Transmission Oil
Hydraulic transmission oil, also known as hydraulic fluid, is a crucial medium in hydraulic systems. It serves multiple important functions. Firstly, it transfers power within the hydraulic system. By converting mechanical energy into hydraulic energy and then back to mechanical energy, it enables the smooth operation of various hydraulic components such as hydraulic pumps, cylinders, and motors. Secondly, it lubricates the moving parts in the hydraulic system, reducing friction and wear, thereby extending the service life of the equipment. Thirdly, it helps in dissipating heat generated during the operation of the hydraulic system, maintaining a stable working temperature. Additionally, it also has anti - corrosion and sealing functions, protecting the hydraulic system from rust and preventing leakage.
