Hydraulic pumps are devices which are not just used in heavy industry, they are also found around the home. If you have a riding lawn mower or a log splitter it might use a motor-driven fluid pump. If you are experiencing problems with it you might need to call in hydraulic pump and motor repairs.
Here are a few of the common problems that might occur and cause you to need hydraulic pump and motor repairs:
There is a Strange Noise
When you hear an abnormal noise in your hydraulic system it is a good sign that you will need hydraulic pump and motor repairs. The noise is caused by aeration or cavitation. Aeration means that a small amount of air has gotten into the hydraulic fluid and is circulating through the system. Every time it compresses and decompresses it will make a banging or knocking sound.
Cavitation means that the fluid within a part of the hydraulic system is less than the volume of fluid demanded by that part. This will cause the absolute pressure to fall below the vapour pressure and form cavities of vapour within the fluid. These will implode when compressed and cause a noise.
Both of these problems can seriously damage the system, so be sure to seek hydraulic pump and motor repairs as soon as possible.
The Machine Has Slowed Down
If the hydraulic system is slowing down, it is a sure sign that something is wrong. It is likely caused by a lack of flow due to leakage, such as in the pump, valves, actuators or a burst hose. This causes the pressure to drop and the performance of the system to slow right down.
The Fluid is Very Hot
If the fluid temperatures in your system are above 82 degrees Celsius you should be looking into hydraulic pump and motor repairs. When the fluid is this hot it will damage the seals and ruin the machine. The fluid is likely overheating because something is reducing the ability to dissipate heat, so many sure that there are no obstructions to airflow around the important components.
These are just a few of the common problems which might require your system to need hydraulic pump and motor repairs.
Your system might require hydraulic pump and motor repairs if you are experiencing any of these common problems.
