Hydraulic machinery is used extensively across a wide variety of industries. Like any equipment, it requires routine maintenance and occasional repairs. The easiest way to keep associated repair costs low is the early detection of any issues with a machine’s Hydraulic Parts in Joliet Illinois. Those responsible for maintaining expensive machinery should keep an eye out for the following early warning signs of impending mechanical failure.
Abnormal Noises
When hydraulic systems begin to make alarming noises, usually in the form of loud banging or knocking, it’s usually a sign of either aeration or cavitation. When air is allowed to contaminate the hydraulic fluid, it is bad news for the machine, as it causes more rapid degradation of the fluid and damage to various hydraulic components. The associated loss of lubrication and overheating can cause seals to give out and the system to break down. Check the pump intake lines and shaft seals, as they are the most common culprits for air intake.
Cavitation refers to an inadequate fluid supply in any part of the hydraulic circuit. The resulting fall in vapor pressure causes cavities to form in the fluid, causing erosion and subsequent fluid contamination. Check the pump filters and ensure the intake line is fully open. Replace parts as needed.
High Fluid Temperature
The temperature of the hydraulic fluid should not be allowed to exceed 180 degrees Fahrenheit. Higher temperatures can accelerate fluid degradation and damage the seals. Ensure that the equipment is well ventilated, particularly around the reservoir. It is also possible that the heat exchanger may need to be replaced.
Slow Operation
Reduced machine performance is usually one of the first signs of impending hydraulic failure. It indicates a lessened flow of fluid, usually due to internal leaking. The most common areas for internal leaks are the valves, actuators, and pumps, but it can be difficult to pinpoint the source of the leak. In some cases, a hydraulic flow tester will need to be used.
Don’t let these warning signs go until the machine has reached complete system failure.
