Modern Monitoring and Control Systems for Hydraulic Power Units
Journal Title: Održavanje - Year 2016, Vol 4, Issue 1
Abstract
The modern hydraulic power unit is not just the tank, pump, drive motor, the basic armature and components for ensuring the cleanliness level of the media and security as well. They need to be equipped with multiple sensors that provide not only safe operation of the power unit, but also help reduce operating and maintenance costs, extend the life of the entire hydraulic system and provide the full control over the operation. Sensors themselves, like pressure sensors, temperature and liquid level, filter blockage,... unfortunately are not sufficient enough for reliable operation of the hydraulic system. Available signals from the sensors need to be reasonably used in the context of an appropriate control and supervisory of the power unit and measured parameters should appear on a suitable interface for visualization (HMI). As an upgrade of the system it is also desirable to the record signals and accesses their history via the Internet with a wired or wireless connection. This type of interaction with appropriate number of modern sensors and designed control system is the only way to provide reliable operation of complete hydraulic power unit and control system. The implementation of such system, including the condition monitoring of the built-in hydraulic fluid is addressing this paper.
