Find hydraulics in some of the most diverse industries, from wind-energy production to construction cranes. While the hydraulic hose and control box might be common parts in users’ minds, the bulk of the work is completed by the hydraulic pump. Explore this primer on hydraulic pumps for dummies. Everyone will know more about these parts with a short discussion.
Although every hydraulic system is unique, such as using boosters instead of pumps, basic designs require two functions from these components, reports Machine Design. These functions are based on simple physics, which makes hydraulics a strong force in many industries, such as the renewable energy sector.
These two functions include these operations, such as:
- Creating an initial vacuum
- Moving liquid from point A to point B
It helps to visualize hydraulic energy as rivers and streams. The pump generates a flow or movement of the liquid so that machinery can activate with reliable actions.
Flow, Not Pressure
When it comes to hydraulic pumps for dummies, it’s important to know that these components don’t produce pressure. That myth is a common misconception about these pumps.
Pumps move a liquid from one location to another. During this process, the fluid itself creates a pressure against the system. It must overcome the system’s resistance, such as the internal walls, to move across hoses and other parts.
Without fluid movement, there cannot be pressure. They are linked, but the pump cannot generate pressure as defined in this system.
According to Hydraulics & Pneumatics, there are many different types of pumps. Each one functions in a slightly different manner, depending on the application.
A few of the most common pumps include these types, such as:
- Positive- and non-positive-displacement
Hydraulic pumps also have subcategories when the internal parts differ from each model. Their functions remain the same, however. They ultimately move fluid through a system for kinetic energy purposes.
Hydraulics depend on pumped storage fluid in order to influence a load. Pumps are certainly reliable, but they may have difficulty adapting to different applications. Parker offers a solution with a specialized load sensing valve.
Add this valve to the system, and it helps the pump move at a more efficient pace. The results are easier control of a machine, which leads to enhanced productivity and cost savings.
Pumps interact with these valves so that the fluid can move at a steady pace without any hiccups. As a backhoe moves into countless positions throughout a job, for example, the pump and valve work together for seamless operation.
Hydraulics & Pneumatics points out that pumps aren’t just for production and construction purposes. The clean energy sector also benefits from a specialized gear pump.
Consider the wind turbine that turns windy days into useful energy for towns and counties. Hydraulics can supplement mechanical motion when windy conditions die down. In turn, the turbine can still supply energy without intermittent downtime.
Although pumps are a traditional type of mechanical solution, they can be used in modern applications that truly make a difference for the environment.
Keeping up With Maintenance
Hydraulics are largely closed systems, but that doesn’t mean that they’re free from regular maintenance. Consider water stored in a system that’s moved around with a pump. Contaminants can arise in the fluid over time.
This same concept applies to hydraulic fluid within pumps. Cleaning or changing filters along with reservoir inspections are crucial to smooth operations. Pumps will break down with contaminated fluid in the system.
