Controlling Hydraulic Oil Temperatures

Causes of Heat GenerationPressure-Compensating PumpsRelief ValvesHeat RemovalEvery hydraulic system generates a certain amount of heat. Approximately 25 percent of the input electrical horsepower will be used to overcome heat losses in the system. Whenever oil is ported back to the reservoir and no useful work is done, heat will be generated. The tolerances inside pumps and valves are normally in the ten-thousandths of an inch. These tolerances permit a small amount of oil to continuously bypass the internal components, causing the fluid temperature to rise. When oil...

Controlling Hydraulic Oil Temperatures Machinery

Pumps and hydraulic motors bypass more oil at high temperatures, causing the machine to operate at a slower speed. In some cases, high oil temperatures can waste electrical energy by making the pump drive motor pull more current to operate the system. O-rings also harden at higher temperatures, leading to more leaks in the system.

Controlling the Speed of a Hydraulic System

The fixed-orifice flow control (Figure 2) may or may not be a proper component in a machine. By definition, it is nothing more than a hole of a specific size that cannot be adjusted. It may be simply a drop in line size. Sometimes when a 2-inch hydraulic line is teed off to a 1/4-inch line, a draftsman may represent this as a fixed orifice.
