Hydraulic systems are used to power a variety of applications, especially in industrial settings. Ignoring easily detectable symptoms of hydraulic issues can lead to equipment failure and a need for a hydraulic repair services. To avoid potential issues, pay attention to the following three common signs of hydraulic system problems: (1) abnormal noises, (2) decrease in operation speed and (3) high fluid temperature.
Abnormal noises in hydraulic systems are often caused by aeration or cavitation.
Cavitation occurs when the volume of fluid demanded in a hydraulic system exceeds the volume of fluid supplied, resulting in the formation of gas bubbles that create vapor cavities. This can be addressed by slowing the fluid flowing through the system.
Aeration occurs when air contaminates the hydraulic fluid. The degradation of fluid is accelerated by aeration and can cause severe damage to system components.
If your hydraulic system is making a banging or screeching noise, it is most likely due to aeration or cavitation.
Decreased Operational Speed
A decrease in operational speed is usually one of the first indications that there is something wrong with a hydraulic system. This usually occurs when there is external or internal leakage, resulting in a loss of flow, and flow controls speed and response.
High Fluid Temperature
Fluid temperatures above 180 degrees (82 C) are detrimental to a hydraulic systems’ operations. High fluid temperatures can damage seals and accelerate the degradation of the fluid. Anything that reduces the systems’ capacity to dissipate or increases its heat load may cause fluid temperatures to rise. The reservoir fluid level should be monitored and maintained at appropriate levels since heat is dissipated through the reservoir.
By listening for abnormal noises, noticing decreased operational speed or detecting a high fluid temperature, you will can likely catch the issue before it turns into a major repair.
