How Do Hydraulic Systems Work?
Hydraulic Systems are dynamic and function by using a fluid that is pressurized and acts upon every part of the system to create force or motion. The heavy-duty equipment that demands the use of a hydraulic system needs to ensure that it is working properly to remain efficient. There are a decent number of things that can go wrong, some easily identifiable and some that typically go unnoticed. Make sure to keep your eyes on any hydraulic equipment repair you may need. Always checking on the system and confirming all the pieces are working accurately is important, if you can catch it early enough, it may not be as costly.
These are some of the main issues that can go wrong with hydraulic equipment and how you can be made aware of the issue and its solution.
5 Most Popular Issues with Hydraulics
Contamination:
Hydraulic system failures can be caused by air, water, dirt, and metal contamination and can create considerable damage to the pump and its surrounding elements over time. The contaminants can get in the system during maintenance, from worn seals or an issue with filtration. You want to make sure that you are maintaining a clean environment while doing any kind of repair or work on the hydraulic system. In addition to your workspace, you will also want to make sure that all the pieces involved are properly cleaned and applied so that you can avoid any contaminants. The discovery of the issue can be discovered by looking at the fluid. The color will be abnormal, possibly milky which could prove it’s water, or dark. Make sure that you flush the system and replace the fluid, double-check the parts and that your space has been cleared of any contaminants, after this your system should function normally again.
Leaks:
Leaks can be a big issue for hydraulic performance, and unfortunately, so can finding where the leak is coming from. Leaks are usually the main cause of the pressure dropping and can result in poor performance and possible environmental hazards. Worn-down, loose, or damaged parts can reduce the pressure and effectiveness of the system’s capabilities. Make sure to check for spots or puddles as well as replace, tighten, and repair anything that requires it after checking over all the involved pieces. By making sure you check the fluid level as a regular practice, you are less likely to carry on with this issue for too long.
Cavitation:
Cavitation is when vaporizing occurs to the hydraulic fluid due to extreme pressure dropping. It can also be caused by several other reasons like poor plumbing from incorrect hose size or aeration and even excessive vacuum conditions. These issues can create tiny bubbles which can end up imploding by moving towards the discharge side of the pump. Damage can be caused to the whole system, especially metal surfaces which will result in friction and wear. Loud sounds, screeching, cracking, rumbling and vibrations can all be signs of cavitation so be sure to watch out for those.
Temperature:
Fluid Viscosity is a very important part of creating a well-conditioned and operating hydraulic system. Viscosity is influenced by both temperature and pressure so hydraulic systems need to have the correct conditions, so the fluid has the right environment. If the temperature is too cold it will cause damage to the system and will affect the fluid’s ability to flow through the system, which can react by having a sluggish performance. If the liquid is too hot, it will reduce its lubricating properties and increase the risk of a leak while slowing down the system. You want to make sure that the fluid level is correct, and that the cooling elements are working properly so that this problem doesn’t occur. You can also use a heat exchange that will aid in removing heat, though smaller systems may not need this because of the flow and transfer of the fluid.
Human Error:
There are a lot of different issues that can come into play with Hydraulic systems, but human error is another one that we sometimes forget about. Poor installation can cause a lot of issues and may lead to the pump being unable to build pressure. Wrong parts can make the system malfunction or not work at all, that’s why it’s important to talk to a professional during the process of installing and maintaining your equipment. Many things can easily be overlooked, so getting confirmation from someone that you are on the right track and following the correct steps can be helpful.
Hydraulic Issues Conclusion:
Understanding what kind of things can often go wrong with hydraulics will help you when working with them so you know what to look for and be aware of. When caught early a lot of these issues can be easily reversed. Although waiting or not catching them in time could result in a lot of damage to the system, as well as a more costly project.
