A lot of machinery in different industries such as construction, mining and manufacturing depend upon hydraulics in order to function. Hydraulic operations depend upon fluid power to do everyday, routine work. In standard operation of machinery using hydraulic power, the fluids are dispensed throughout the motors and cylinders of the machine. The direction of these fluids is controlled by hydraulic control valves, which then moves the fluid through various hoses and tubes. Those of you who work with or around any machines in Illinois and are unsure if you need repairs of your Hydraulic Valves in Aurora, IL, consider these tips on detecting hydraulic-based issues.
- One of the problems that occur with hydraulic systems is the drift, of which there are two types: the constant actuator drift and the null drift. When a valve is what they call “out of null,” this indicates that the piston is moving and/or drifting very slowly when there is no known signal. An example would be when the electrical power has been disconnected. This issue becomes a serious problem when the drift rate is high or going in the wrong direction. If the process in which the hydraulic system is needed requires rapid movement, this drift problem will greatly hamper it. If the problem escalates into the null drift status, it is indicative of back-pressure issues, flow forces, or poor spool control where the valves are concerned.
- Another issue that arises with hydraulic systems is that of deadbands. For example, if a valve has a deadband region of 20 percent, the controller must now operate a control signal at 20 percent just to get to the point where the hydraulic oil will begin to flow.
Miller Hydraulic Service Inc. which started over 18 years ago, operates in the Aurora, IL, Manteno, IL, Chicago, IL, Joliet, IL and the Gary, IN areas. They repair hydraulic components for every kind of machine you can find them on. This includes cylinders, pumps, motors and valves. They weld and fabricate any part to meet your mechanical requirements. If you need them to weld or fabricate Hydraulic Valves in Aurora, IL and the surrounding areas.
