Hydraulic equipment is everywhere and most of us never notice it. For example, there are many types of hydraulic pumps, brakes, and electric motors on a typical domestic vehicle. If you own a boat, the hydraulics will help steer it. Thanks to backhoes, hydraulic components on bulldozers, and many complex machinery in manufacturing sites, enterprises from construction sites to machine shops are operating efficiently. This articleZhongyou Heavy IndustryBrings signs that hydraulic equipment needs maintenance.
In today's world, we must inspect and maintain these systems because we rely on hydraulic equipment to keep them running smoothly. Know the signs tell us there's something wrong with them. Ignoring the symptoms of hydraulic problems can lead to equipment failure, expensive repairs or even total replacement.
To avoid potentially serious problems, pay attention to the following four common signs of hydraulic system failure:(1) abnormal noise;(2) reduced operating speed;(3) high operating temperature; and (4) leakage.
1) Loud or unusual sounds:
Abnormal noise from the hydraulic system is usually caused by inflation or cavitation. When air contaminates the hydraulic fluid, it can vent and degrade, damaging the components of the system.
Cavitation occurs when the fluid demand of the system exceeds its supply, resulting in the formation of bubbles and the formation of a vapor cavity. This can sometimes be mitigated by slowing the velocity of the fluid flowing through the system.
Remember that any mechanical parts will wear out and stop running at their best. Whenever you hear an unusually loud noise from hydraulic equipment, it is almost certain that this will require repair or replacement.
2) Operating speedDecrease：
If your hydraulic system slows down or has a long cycle time, it usually indicates a problem. One of the main reasons for this slowdown is leakage. You may have realized that the flow rate determines the speed and response of the actuators within the system. Therefore, it follows that the speed loss is usually caused by the flow loss.
In the event of an external or internal leak, the flow in the hydraulic circuit may escape. External leaks, such as a broken hose, are usually easy to find and repair. Internal leaks in pumps, actuators or valves are more challenging to diagnose.
3) High fluid temperature:
Hydraulic systems require a specific level of viscosity to function correctly. And because temperature is one of the factors that control viscosity, it needs to be kept within the limits recommended by the system manufacturer. Fluid temperatures above 180 degrees Fahrenheit (82 C) may be hazardous to the operation of the hydraulic system.
Higher fluid temperatures can damage the seals and accelerate fluid decomposition. If the system is not sufficiently cooled, it will be subjected to excessive strain, which may eventually lead to premature failure.
Since the heat is spread through the reservoir, it is important to check regularly and maintain the correct liquid level.
4) Leakage:
As mentioned earlier, leakage will adversely affect the hydraulic system by reducing the system pressure, thereby increasing the operating temperature. This increase, in turn, affects the viscosity of the fluid, further reducing the pressure.
Once you see liquid outside the pump, the problem has been resolved and you must take immediate measures, because leaks are usually a sign that the hydraulic system is about to die!
