Key Components: Hydraulic System

We have been looking at the key components that make up a piece of drilling equipment. We talked about tracks as a propulsion system and what to look for when inspecting them for wear. Moving up the ladder, so to speak, is the hydraulic system. They hydraulic system is made up of many different components and driving the tracks is generally a set of hydraulic motors. Basically a hydraulic motor is utilized to turn the tracks through fluid power. The system works like this, a pump provides pressurized fluid to the motor through a series of valves. Drive motors are generally of a variable displacement configuration allowing the speed of output to be regulated.

All About The Fluid

dreamstime_xxl_17475168Unlike the drive motors, the main hydraulic pump is generally of a fixed displacement and has a set GPM, (gallons per minute). The pressure of the hydraulic fluid is generally regulated by relief valves and components that provide a certain amount of leakage. There can be literally hundreds of small orifices and check valves to regulate pressure and if one of these passages are compromised, the entire system will not function correctly. This being the case, the most important thing to remember when inspecting the hydraulic system is that the fluid must be in good shape. Checking the hydraulic fluid is as easy as popping the cap and putting some of the fluid onto a white rag or paper towel. Fluid in good shape (depending on the brand) will smell sort of like plastic and be tan in color. Fluid that should be suspect will have a brown tint and maybe small flakes of metal floating in it. This could indicate an issue in the pump, the motors or anywhere inbetween.
