Almost every hydraulic system will pressurize the fluid stored in the reservoir with a hydraulic pump and will pass it towards other hydraulic system components. This is true regardless of the size of the hydraulic system, so the pump is a very important component as it converts mechanical energy to hydraulic energy. Damage to a hydraulic pump can affect the performance of your hydraulic system and can impact its efficiency as well. To prevent this from happening, regular maintenance of your hydraulic pump is a must, as this will eliminate the possibility of costly and irreparable damage.
It is important to spot minor damages early on so that they can be easily fixed. If you detect damage of any kind, you need to first inspect your system so that you understand the root cause of that failure and must check the pump type and its specifications, any symptoms the pump indicated before the failure and when the oil was refilled last. You should also consider the type of oil that was used and whether or not it is compatible with your system. These aspects need to be considered before dismantling or repairing your pump because you will be able to apply the proper solution accordingly.
Loud noises, high oil temperature and a slow or inefficient pump are all common signs of hydraulic pump failure, and the following guide will go into more detail regarding the different types of repairs:
Noisy Hydraulic Pump
Cavitation, aeration, coupling misalignment and a worn or damaged pump can all cause a hydraulic pump to be noisy. The formation of gas bubbles is known as cavitation, and you can eliminate this issue by cleaning or repairing the filtration components or by replacing the hydraulic fluid. Aeration is similar and occurs whenever air is entrapped in the hydraulic fluid. This issue can be fixed by tightening any leaky connections, replacing seals and filling fluid to the required level. Properly aligning the seals, couplings and bearings will help efficiently remove coupling misalignment issues, and if you have a worn or damaged pump, you will have to replace it.
Cavitation, aeration, excessive load and a damaged pump can all cause a pump to overheat, and this will affect the fluid viscosity and will also cause wear to system components. The remedies for cavitation, aeration and a damaged pump are the same as listed above but to tackle an excessive load, you need to first understand the working load capacity of that pump. Installing a pressure gauge and adjusting the pressure settings will help remove excessive heat.
Slow or inefficient pump
The pump plays a very important role in converting mechanical energy to hydraulic energy, so pump efficiency is very important. In addition to the issues mentioned above, low oil level, stuck inner components and low oil viscosity can also cause a pump to be slow and inefficient, so try replacing hydraulic oil or filling it to the required level.
