If you’ve ever stepped in an elevator, landed somewhere in a plane, or ridden an amusement park ride, you’ve experienced the work of a hydraulic pump. And in all these scenarios, you would probably shudder to think of what would happen if the hydraulics suddenly gave out. That’s why being aware of the common symptoms of hydraulic pump problems is so important.
Sounds
The first indication that something is going wrong in a hydraulic system is unusual noises such as banging, clanking, rattling, whirring, or grinding. These sounds occur when air contaminates the hydraulic fluid. It may also be caused by the fluid not being evenly distributed throughout the motor, causing the pressure levels to drop in parts of the system.
Temperature
Hydraulic systems are designed to be self-cooling. So, when the temperature of the system or the fluid gets unexpectedly high, this can indicate an issue with the filters or the hydraulic fuel reservoir. This excess heat can cause even greater problems in your hydraulic pumps, such as deterioration of surfaces, damage to rubber seals, and a loss of fluid viscosity.
Leaks
If your pump begins leaking any type of fluid, this is typically a sign of a problem. If you see external leaking, it may point to a problem with the seals or tubing of a system. However, not all leaks are visible from the exterior. Most hydraulic pump leaks occur inside and will be indicated by a sudden drop in the system’s pressure.
Hydraulic pumps and motors power a wide variety of everyday technology. So, the last thing anyone wants to do is ignore signs that a hydraulic system is failing. Recognizing the signs of hydraulic pump problems so operators and owners can
locate a hydraulic repair shop will help protect those working and living in and around hydraulic pumps.
