Welcome to the topic 9 Ways To Make Sure Your Hydraulic System Works Properly.
Many jobs that can be too challenging to complete manually are assisted by hydraulic devices. The hydraulic pumps, motors, cylinders, and other parts all cooperate to make sure the machinery functions properly.
To keep them operating as planned, hydraulic systems do need routine maintenance and inspections. Most of the time, proper maintenance and inspections can aid in identifying issues and preventing system failures.The following hydraulic system inspections should be performed routinely before, during, and after using the system.
Several industries use hydraulic systems for a wide variety of tasks. Hydraulic systems speed up work completion by saving time, enhancing worker safety, and pressing or lifting big weights. Maintenance of the hydraulic system is essential for it to continue functioning as intended. Learn what has to be monitored and checked each time the machinery is used.
1. Verify fluid levels
Check the amount of hydraulic fluid in the tank or reservoir before each operation of the machinery. The hydraulics must have the right amount of fluid in them in order to create the full pressure they require to perform the task you need them to.
If the oil level in the tank is low, you might start to draw air into the system, which could cause the pump to cavitate and drastically lower system pressure. Whenever you add oil to the tank, be sure to use the same viscosity and grade of oil as is currently in the system.
2. Verify the Filter Indicators.
The majority of hydraulic systems use filters with indication windows so you can see when the filter needs to be changed. Before starting the machine, check the filter indications since contaminated filters can pollute the entire system and harm the pump, servos, and hydraulic cylinders.
3. Inspect the Aeration in the Tank.
Checking for air bubbles in the hydraulic oil in the tank is the quickest and easiest technique to determine whether your system contains air. When the system is operating, the oil shouldn’t be foamy on the surface. Examine inside the oil tank through the fill hole using a flashlight. There may be an air leak in the system if you notice air bubbles on the oil’s surface.
Inadequate cylinder seals, cold hydraulic oil, and oil that is too viscous for the system are additional sources of aeration. Pay attention to the hydraulic pump to see whether there is air in the system. Because it is cavitating and unable to pressurize, it frequently makes noise.
4. Examine the system’s temperature.
Check the temperature of the lines, the servos, and the pump frequently using an infrared thermometer. High system temperatures have the potential to harm the parts, necessitating an early replacement. When fully heated, most hydraulic systems should operate at or below 180 degrees Fahrenheit.
5. Verify the hydraulic fittings and lines
Spend a moment visually inspecting the hydraulic fittings and lines throughout the system. Check for cracks in the hoses, leaking fittings, or leaks in the lines. Before using the machine, make repairs if you see any of these.While the system is not in use, leaks may go undetected. When there is pressure in the lines and warm fluid in the system, turn on the equipment and perform your examination. This is when a leak or drip in the system is most likely to be seen.
6. Examine the Hoses
Hose damage is the most frequent reason for hydraulic fluid leakage. When the system is running or after you shut it down, clear off any muck that has accumulated on the hoses and look for leaks. Just use caution, as hydraulic fluid can get rather warm.
You should also verify the hose’s length, route, and quality as part of your examination. Hoses stiffen and become more challenging to bend as they age. If the hose wall is failing, you can also see scorching or bubbling in different areas of the hose.
7. Observe the Sounds the Hydraulic System Makes
When in use, all hydraulic machinery and systems emit noise. You ought to be familiar with the noises that denote proper operation. When the sounds alter, it typically means that a hydraulic repair is required. For instance, if you hear a whining noise, it may indicate that the pump is cavitating and fluid flow is restricted. This can be a sign of an obstruction at the pump’s inlet, an empty reservoir, a broken pump inlet fitting, or a clogged intake filter.
8. Examine the Breathable Caps
When doing inspections, maintenance, and repair work on a hydraulic system, the breather caps or breather filters are frequently one of the most neglected components. The breather cap aids in preventing external sources from introducing fluid pollutants into the fluid reservoir.
9. Check the system pressure routinely.
To keep fluid power going, the system pressure needs to be just right. Keep track of the pressures in your system taken when it is working properly to serve as reference pressures.
You need to be aware of how hydraulic accumulators and cylinders affect system pressures. A malfunctioning pressure control valve, accumulator, or air leak in a hose or pipe could also be the cause of unexpected pressure decreases or spikes.
