Some common problems with hydraulic systems include aeration, reservoir damage and leakage. Carrying out routine maintenance practices is key to avoiding most problems associated with hydraulic systems, notes MachineryLubrication.com.
When a hydraulic system develops a problem, there are often symptoms that can be observed; this makes it possible for repair work to be initiated relatively quickly. Aeration or cavitation within the system usually causes an abnormal noise. Aeration is a term that describes the contamination of the hydraulic fluid by air, and this problem usually leads to faster degradation of the hydraulic fluid. As a result the system loses lubrication and starts to overheat. To remedy this situation, it may be necessary to replace inlet pumps. Check to see if all seals are in place and fill up the fluid to the correct level.
External or internal leakage at any part of the system may lead to slower operations. External leakages are usually traced to a burst hose, while internal leakages are normally attributed to parts such as actuators, valves or pumps. Checking these parts of the system can be a good way to establish the exact cause of leakage.
Another common hydraulic system problem takes the form of low levels of fluid in the reservoir. When fluid levels drop, the system is likely to start producing high temperatures. To correct this problem, check the fluid level and replenish it to the correct amount.
