Hydraulic Pumps: Applications and Functions

The hydraulic pump is a fundamental component of the hydraulic system, whose structure combines cylinders, pistons, and gears. Are you confused about what the functions of hydraulic pumps are and which fields they can be used in? This article will introduce hydraulic pumps to you in detail, so that you can have a deeper understanding of how hydraulic pumps apply to your hydraulic products.

What is a Hydraulic Pump?

A hydraulic pump generates power by transmitting hydraulic oil. The hydraulic pump follows Pascal’s law, transforming mechanical energy into hydraulic energy, which achieves a power transmission. Due to hydraulic pumps needing to withstand operating systems and the hydraulic fluid, you can choose durable materials such as steel, stainless steel, aluminum, etc.

A hydraulic pump aims to push pressurized fluid through a hydraulic system. The hydraulic pump itself doesn’t create power. But when the hydraulic fluid encounters resistance, the fluid will then create pressure for running your hydraulic products.

What are the Functions of Different Types of Hydraulic Pumps?

Next, we will give you a detailed introduction to the function of the three hydraulic pumps below.

Hydraulic Gear Pumps

The hydraulic gear pumps make use of rotating cogs or meshing gears to move fluids. You can use them for different environments. They can be applied to applications that need a consistent flow at moderate pressures.

They can be classified into two categories. First, external gear pumps perform effectively and are seen as straightforward machines. You can often see that they can be used with spur, helical, or herringbone gears. And their working principle is to use two meshing gears to create a pumping action for you.

Then let’s talk about the second one, internal gear pumps. The kind of pumps only use spur gears, helping achieve smooth and consistent movement. So they are best suited for pumping high viscosity fluids such as asphalt, chocolate, and adhesives.

Hydraulic Piston Pumps

The hydraulic piston pumps are, in essence, the movement of the piston in the cylinder, which causes the hydraulic oil to be discharged, making it work in the hydraulic system.

They can also be divided into two types. For axial piston pumps, the pumps in the cylinder block do up and down movements as the drive shaft rotates. When the piston moves in one direction, fluid is drawn into the pipeline. And when the piston moves in the opposite direction, it discharges through the passage, thereby enabling continuous fluid flow.

And for a radial piston pump, it is made of a cylinder block, a rotating camshaft, and pistons. As the shaft rotates, the pistons reciprocate within their respective cylinder bores, informing a pumping action.

Hydraulic Vane Pumps

A hydraulic vane pump is a positive-displacement devices that combine a housing, a rotor, and vanes. They have modular designs with flexible ports and mounting options, providing you with a super convenient operation environment. You can always see them being used in high-pressure applications such as heavy machinery and industrial equipment.

Applications of Hydraulic Pumps

Hydraulic pumps are used for various applications. They all play an important role in promoting your hydraulic products more efficiently. Next, we will show you different applications of hydraulic pumps.

Agriculture

In agricultural fields, hydraulic pumps are used to provide the necessary motor and energy for all kinds of agricultural machines, such as plows, seeders, and sprayers. You can use this kind of force and control to operate these machines. Most importantly, hydraulic pumps in agricultural applications can improve the efficiency and precision of running your agriculture and managing your livestock. So that hydraulic pumps can reduce your labor force time.

Construction & Earthmoving

Hydraulic pumps in construction and earthmoving applications are applied in excavators, loaders, bulldozers, and cranes. The hydraulic pumps provide a stable motor for safe control movements and excellent load handling. This power can also be provided for precise and high-force movements. The hydraulic cylinders and motors of your hydraulic pumps can take control of the specific parts of these machines.

Mining & Drilling

In the mining and drilling field, hydraulic pumps provide power for heavy-duty hydraulic equipment. These heavy-type machines include hydraulic rock drills, crushers, excavators, and specialized drilling rigs. You can often see these machines being used in drilling earth, transporting materials, moving large rocks, and more. Pumps can generate large energy from compact components to operate your machines more efficiently and safely.

Transport & Logistics

Hydraulic pumps are often used in the transport and logistics fields, so you can use hydraulic pumps in your truck. You can see that auxiliary equipment like power take-offs, is being used to drive the trucks for better delivery distance. And the hydraulic braking systems can help a lot to brake your trucks, so that ensure your safety. Lifting mechanisms in trucks can help lift and lower cargo, then save labor and your time.

Manufacturing & Industrial Automation

Hydraulic pumps in manufacturing and industrial automation are essential parts. They are often applied in presses, molding machines, and conveyor systems. The hydraulic pumps in these machines can achieve high-force applications, smooth motion, and variable speed control abilities. You can use hydraulic pumps together with jacks and engine hoists for lifting heavy loads and pulling engines. So that the equipment with hydraulic pumps can withstand a severe environment and still perform well to improve working efficiency.

Conclusion

This article shows you the applications and functions of hydraulic pumps. If you want to drive your hydraulic products to produce a large amount of power with minimal loss, then you could turn your eyes to hydraulic pumps.
