Whether you’re looking for help finding the right product from our range of hydraulic pumps, or simply want to learn more, we’ve got you covered. Below, we’ve compiled a list of questions and answers to impart some knowledge on these vital components.
How does a hydraulic pump work?
Hydraulic pumps can be found at the heart of any hydraulic system, turning mechanical power into hydraulic energy. And whilst there is a variety of different types of pumps, gear pumps stand out for their simplicity and efficiency. These pumps work by meshing interlocking gears within a tight enclosure. As the gears rotate, they create a vacuum that draws fluid into the pump, the subsequent displacement chosen, and the calculated KW power of the electric motor then creates the fluid pressure that is needed to operate the system.
How to tell if a hydraulic pump is bad?
As mentioned previously, since hydraulic pumps are integral to the operation of hydraulic systems, identifying when they might not be operating at peak performance is essential. Some telltale signs that your pump may be experiencing issues include:
- Reduced hydraulic pressure
- Noisy operation
- Visible leaks around the pump
- Irregular performance
The timely detection of these issues can prevent costly repairs and significant machine downtime.
How to adjust a hydraulic pump output pressure?
Every hydraulic system is different, so the ability to adjust the hydraulic pump output pressure is essential for optimising performance and meeting requirements. One solution to this is integrating a relief valve into the system. This would enable the operator to alter the valve’s settings to adjust the pressure. It’s important to note that you should always adhere to the recommended working pressure to ensure safe operation.
How to bleed a hydraulic pump?
Bleeding a hydraulic pump is a necessary part of maintenance that allows the system to expel any trapped air that would otherwise hinder its performance. This can be completed by first locating the bleed valve, often found at the highest point of the system. Once the system is depressurised, open the valve slowly to let out the air until a steady flow of liquid is seen, then close the valve again.
How to fix a hydraulic pump?
If your hydraulic pump is showing signs of malfunction, it is important that you get this seen to by an expert immediately. Depending on the issue, fixes can be as simple as replacing a worn seal or damaged gear, or may require a more thorough inspection. As a team of experienced engineers, we can perform a full inspection of your system to identify any faults and complete any necessary repairs to get your hydraulic system operating at peak performance.
