Using hydraulics (or fluid power) is a complex area of science. Whether it’s used in your workplace or not, hydraulics are everywhere, from the brakes inside your car to farming equipment. It can be complicated to understand, so we’ve put together a brief guide to understanding where this science came from and how hydraulic power works. Whether you work with hydraulics, wish to pursue a career in an industry that uses them or need help understanding it for a school science test coming up, our blog can hopefully help.

BRIEF HISTORY

In short, hydraulics is the power of “fluid in motion” and fluid in motion has been a powerful source of energy for thousands of years. Water was used to turn wheels and push levers but evolved from this into fluid power that would pressurise fluids to produce powerful forces. In the 1600s, a physicist named Blaise Pascal realised that pressure on a confined fluid exerted an equal force in all directions, and those forces could potentially be harnessed. From that, many put this into practice, implementing the ideas into mills and hydraulic presses. But the basic science of hydraulics and fluid power is known as Pascal’s Principle.

HOW DOES IT WORK?

In short, a hydraulic system uses compressed fluid to transfer force applied at one point to another point. Take a water pistol, for example; by pressing on the trigger, a large force is applied that moves the trigger a short distance and, because the water won’t squeeze into a smaller space, it gets forced through the pistol to the narrow nozzle before squirting the water with less force but more speed. This process is a simplified version of a hydraulic system or pump.

In a bigger form, hydraulic systems are made up of many components, carefully constructed together to create energy to lift, carry, open or push objects. And, they are powerful – in theory, if a hydraulic system is crafted with a 2-inch cylinder, it will be able to create more than 4,700 pounds of force, easily lifting an average sized vehicle.

Whether you use hydraulics in your everyday job or not, hydraulics are an important part of our modern world and it’s predicted that they’ll be around for thousands and thousands of years.

Understanding the Basics of Hydraulic Gear Pumps

Hydraulic systems play a crucial role in a wide range of industries, from construction and agriculture to manufacturing and aerospace. At the heart of many hydraulic systems is the hydraulic gear pump, a vital component that converts mechanical energy into hydraulic energy. In this blog, we will delve into the workings of hydraulic gear pumps, their types, advantages, and common applications.

What is a Hydraulic Gear Pump?

A hydraulic gear pump is a type of positive displacement pump commonly used in hydraulic systems to generate flow by displacing hydraulic fluid. This pump uses the meshing of gears to pump fluid by displacement. As the gears rotate, they create a vacuum at the pump inlet, drawing fluid from the reservoir into the pump. The fluid is then trapped between the gear teeth and the pump casing, and is carried around to the outlet side of the pump, where it is forced out into the hydraulic system.

Types of Hydraulic Gear Pumps

1. External Gear Pumps

External gear pumps are the most common type of hydraulic gear pump. They consist of two identical gears, one driven by a motor and the other idler gear. As these gears rotate, fluid is trapped in the spaces between the gear teeth and the pump casing, moving it from the inlet to the outlet.

Advantages:

Simple design and construction

High efficiency

Relatively low cost

2. Internal Gear Pumps

Internal gear pumps feature a pair of gears of different sizes. The larger outer gear (annular gear) has teeth on its inner surface, while the smaller inner gear (rotor) meshes with it. As the gears rotate, fluid is drawn into the spaces between the teeth and is carried to the outlet.

Advantages:

Smooth and quiet operation

Capability to handle a wide range of viscosities

Good suction characteristics

3. Gerotor Pumps

Gerotor pumps are a type of internal gear pump where the inner gear (rotor) has one less tooth than the outer gear (stator). This design creates a continuous flow of fluid with minimal pulsation, making gerotor pumps ideal for applications requiring smooth fluid delivery.

Advantages:

Compact size

Low noise levels

Consistent flow rate

How Does a Hydraulic Gear Pump Work?

The operation of a hydraulic gear pump is relatively straightforward. Here is a step-by-step explanation of how it works:

Inlet Phase: As the gears rotate, the space between the gear teeth on the inlet side increases, creating a vacuum. This vacuum draws hydraulic fluid from the reservoir into the pump.

Transport Phase: The fluid is trapped between the gear teeth and the pump casing. As the gears continue to rotate, the trapped fluid is carried around the casing towards the outlet.

Outlet Phase: The space between the gear teeth decreases as the gears approach the outlet side. This reduction in space forces the fluid out of the pump and into the hydraulic system.

Sealing and Pressure Generation: The meshing of the gears creates a tight seal that prevents fluid from leaking back to the inlet side, ensuring that the pressure is maintained within the hydraulic system.

Advantages of Hydraulic Gear Pumps

Hydraulic gear pumps offer several benefits that make them a popular choice in various applications:

Understanding Hydraulic Gear Pumps: The Heart of Fluid Power Systems

Hydraulic gear pumps are integral to many industrial and mobile machinery applications, providing the power needed to move fluids with precision and efficiency. These pumps are known for their reliability, durability, and ability to handle high-pressure conditions, making them a staple in hydraulic systems. In this blog, we will delve into the mechanics of hydraulic gear pumps, their applications, benefits, and maintenance practices.

What is a Hydraulic Gear Pump?

A hydraulic gear pump is a type of positive displacement pump that uses the meshing of gears to pump fluid by displacement. They are commonly used in hydraulic systems to convert mechanical power into hydraulic energy. The pump typically consists of two gears - the drive gear (connected to a motor) and the driven gear. As these gears rotate, they create a suction at the pump inlet, drawing hydraulic fluid into the pump, which is then carried around the gears and forced out through the pump outlet under pressure.

How Hydraulic Gear Pumps Work

Suction Phase: The rotation of the gears creates a void, or low-pressure area, at the pump inlet. This low pressure draws hydraulic fluid into the pump from the reservoir.

Trapping Phase: The fluid gets trapped between the gear teeth and the casing as the gears continue to rotate.

Discharge Phase: As the gears mesh together on the discharge side, the trapped fluid is forced out of the pump outlet at high pressure.

This straightforward yet effective mechanism ensures a continuous and steady flow of hydraulic fluid, which is crucial for the operation of hydraulic systems.
