Need for proper care and maintenance is much important for every hydraulic system. Either it is a simple or complex hydraulic system, better performance can be achieved only with regular system inspection and maintenance. In a fluid power system, there are many factors that need to be monitored regularly and this will include fluid quality, fluid level, component malfunctions, hydraulic pressure, fluid flow, system temperature and more. Identifying hydraulic system failures as early as possible and rectifying them will increase the service life of the system.
The key consideration for hydraulic system troubleshooting is identifying the primary reason for failure. Detecting the exact reason for hydraulic failure is difficult because there are various hydraulic problems that indicate common symptoms. Noise, vibration, and overheating are the common symptoms of hydraulic system damage that can be recognized easily. But, these symptoms occur because of various problems like hydraulic leakages, contamination, component failure, etc…
Also, every troubleshooter or service technician needs to have complete knowledge about the hydraulic system on which they are working before beginning the procedure. A hydraulic system schematic is required for analyzing the system design and specifications. A troubleshooter, who is capable of reading and analyzing hydraulic schematics can identify the desired value for each parameter for the circuit with their experience after reviewing the circuit schematics.
For inspection, a reliability checklist needs to be prepared first. This checklist will note the status of different factors like hose & clamp conditions, fluid level, electric motor reading, temperature reading, pressure reading, breather condition, oil cleanliness, etc… These factors will help troubleshooters to make preventive maintenance by predicting the possibilities of failure and to identify which part of the system is not working.
Different accidents may occur if the troubleshooting is not handled properly by following safety practices. So, every troubleshooter needs to give primary consideration for their safety and they need to be aware of hydraulic risks. Wearing safety glasses, hand gloves, insulating mats, and hard hats while inspecting or repairing hydraulic systems will protect the user from serious safety hazards.
To ensure safety, every operator needs to make sure that all power lines to the system are turned off. The operator can check the voltmeter to verify that no power is supplied to the machine. The next is to carefully examine the problems mentioned by the system operator. With these symptoms, the troubleshooter can make certain assumptions and perform diagnosis. The damaged components can be either replaced or repaired based on inspection results.
To conclude, the important factors that a troubleshooter needs to consider are function of the component, troubleshooting knowledge, ability to read hydraulic symbols, and experience for adjusting systems based on requirements. Also, following the safety guidelines while troubleshooting will prevent jobsite hazards to a greater extent.
