  • Hydraulic oil: The life of the hydraulic system

    2020-1-28 · Suffice to say, the life of the hydraulic system is primarily tied directly to the life of the oil. When oil is kept clean and below 140° F the entire system benefits. Viscosity . Because the oil in hydraulic systems does a dual purpose of lubrication and transmission of power, it’s important to take viscosity into account.

    A simple hydraulic pump starts out with a pipe that brings the water from the source. At the very end of the pipe is a valve, called the waste valve.When under pressure, the waste valve closes, backing up water pressure against another valve further back, called the delivery check valve.This valve leads to the outlet or delivery pipe.
