If you have noticed that your factory's hydraulic pump has become sluggish, you may wonder if there is an internal issue causing the trouble. If so, look for the following problems with the hydraulic fluid that may indicate a failure within the pump.
Fluid Has a Foamy Consistency
One indicator to look for when examining the hydraulic pump's fluid is the presence of foam. If the hydraulic fluid has a foamy consistency, air is leaking into the system and becoming trapped within the fluid.
When you find foam in the hydraulic fluid, there are two possible causes. First, a gasket may be broken and is allowing air into the system. Second, the pump may be pulling air inside of itself and contaminating the fluid.
If either of these scenarios happens, the increased pressure produced by the air can slow down the machine's pumping action. The increased pressure could also lead to more ruptured gaskets or damage to the pump itself.
If you are unable to easily examine the fluid for the presence of foam, listen carefully to the system while it is running. If you hear any loud banging or thumping noises, these indicate that the pump is fighting against air pockets while it attempts to operate.
Temperature Gauge Shows the Fluid Is Overheating
Another way to use the condition of the fluid to diagnose an issue with the hydraulic pump is to keep an eye on the temperature gauge. When the fluid and pressure within the pump stays below the red zone, the pump is likely working as it should.
However, if the gauge's needle continuously enters the red zone, this position means that the fluid is overheating. If the fluid overheats, areas become thinner than others, leading to unequal pressure within the hydraulic system.
As the pump operates, the inconsistencies in the thickness of the fluid create subtle differences in pressure as it pumps the fluid. Whenever the pump has to work harder to push the thicker fluid through the system, the sudden spikes in pressure could lead to broken gaskets or damage to the pump.
If you have noticed any of the problems above with the hydraulic fluid, there is a good possibility that there is an issue with the hydraulic pump itself. Contact a company for hydraulic system engineering services, including repair services, to have them inspect your pump and discuss with you options for fixing the problem.
