Hydraulic pumps are vital pieces of equipment, and if they malfunction, you will find yourself in dangerous and tricky situations. To prevent this from happening, you need to check your hydraulic pump regularly to ensure it is in good condition, and if you notice any of the following signs, it may be time for a replacement:
If you hear strange or loud noises coming from your hydraulic pump, it is a big sign that there is a problem. While there are a lot of fluids that course through the system at high speeds, hydraulic pumps are specially designed to muffle these types of sounds, so you should not be hearing these types of noises.
If you do hear them, it is an indication that some part of your hydraulic pump is in need of a repair or a replacement.
Leaks On The Inside
Liquids should only be found in the tubes where they belong, so if you see liquids anywhere else inside the pump, it is a sign that something is wrong. It can be a minor issue and can be a simple case of a seal or valve being loose, but it can also be more serious, and there may be a break in the line.
Whatever the case, inside leaks need to be addressed because this issue can cause a drop in pressure and can cause the entire system to malfunction. This is a tricky problem to detect because leaks occur inside of the pump, but if you examine it carefully, you will be able to spot the problem before it is too late.
Leaks On The Outside
If your leaking problem progresses, you will notice liquid on the outside of the pump, and this is very problematic, so you need to take action right away.
This type of leak is an indication that the pump is sure to fail, so you need to address this issue immediately as it can cause a chain reaction. A leak will reduce the pressure, which will then increase the temperature of the system, and this will affect the viscosity of the oil and will further reduce the pressure in your system, so you need to fix this problem right away.
High Working Temperatures
You need to keep a certain level of fluid viscosity for your hydraulic pump to function properly, and because the viscosity of a fluid depends on the temperature and pressure, both of these aspects must be within the limits recommended by the pump’s manufacturer.
If one of these aspects is incorrect, it will place unnecessary strain on your pump, which can lead to premature failure. High temperatures will have a negative effect on the performance of your pump and must be avoided.
