Hydraulic pump and its role in power systems

What is a hydraulic pump?

A hydraulic pump is one of the most important and vital components of any hydraulic system, whose function is to convert mechanical energy into hydraulic energy by creating oil flow and pressure. By sucking oil from the tank and sending it to the circuit, this component provides the basis for creating force and movement in cylinders, hydraulic motors and other consumer components. The accurate and reliable operation of the hydraulic pump plays a direct role in the power, speed, efficiency and lifespan of industrial, road construction and heavy machinery.

Hydraulic pumps are produced in various models, including gear, piston, vane (cartridge), and radial, depending on the type of application. Gear pumps usually have a simpler structure and are suitable for medium pressures, while piston pumps are used in heavy machinery such as loaders, excavators and bulldozers due to their ability to withstand high pressures and greater efficiency. The type and capacity of the hydraulic pump should be selected according to the needs of the system to prevent problems such as pressure drop, oil heating and power loss.

Kavir Machine Espadana Company, by providing new and stock original parts with a guarantee of product authenticity, always strives to meet the needs of its customers in the field of supplying heavy machinery parts in the best way. This part is available to our valued customers ready for delivery and with a guarantee of product authenticity.

Types of hydraulic pumps:

1. Gear hydraulic pump

A gear pump has a simple and robust structure and directs oil into the circuit by engaging two gears. This type of pump is suitable for medium pressures, has low maintenance costs and is mostly used in lighter devices or low-pressure circuits.

2. Piston hydraulic pump

A piston pump uses multiple reciprocating pistons to create high pressure. Its features include very high efficiency, high pressure tolerance and precise operation. These pumps are most commonly used in heavy machinery such as loaders, excavators and mining equipment.

3. Cartridge hydraulic pump

In a vane pump, movable vanes are located inside the rotor and move the oil as it moves. This pump operates quietly, without vibration and with low noise and is very suitable for industrial applications and medium-pressure machinery.

4. Radial hydraulic pump

A radial pump works by placing several pistons in a radial direction around a central axis. These pumps are capable of producing very high pressures and are used for special equipment and systems that require extremely high pressure.

One of the important points in the proper operation of a hydraulic pump is the quality of the oil and the health of the filters. The presence of metal particles, contamination or a decrease in the oil level can cause severe wear of the internal parts of the pump, reduce efficiency and even lock it. For this reason, periodic service, timely filter replacement, and use of standard oil are among the most important aspects of pump maintenance. Also, proper pump installation and prevention of leakage at the inlet play an important role in preventing cavitation; a phenomenon that can cause serious damage to cams, pistons, and distribution plates in a short period of time.

Ultimately, the hydraulic pump is the beating heart of hydraulic systems, and its precise operation guarantees the speed, power, and efficiency of the system. Choosing a high-quality model, proper installation, and proper maintenance can increase the useful life of the device and significantly reduce repair costs.

Hydraulic Pump in Mining Machinery

The hydraulic pump in mining machinery is one of the most critical components of the power system, which is responsible for providing the pressure and flow necessary for the accurate operation of heavy equipment. By converting the mechanical energy of the engine into hydraulic energy, this pump provides the power required to move the boom, bucket, jacks, steering system and other active parts of machines such as loaders, excavators, bulldozers and dump trucks. In harsh mining conditions—from heavy dust to working on slopes, humidity and heavy loads—the hydraulic pump must have resistant alloys and a robust design so as not to suffer from pressure drop, leakage or premature wear. Hydraulic pump failure can reduce the machine’s power, slow performance, increase fuel consumption and even stop operations completely; for this reason, periodic maintenance, use of standard oil, timely filter replacement and system temperature control are among the most important factors in increasing the useful life of the hydraulic pump in mining machinery.
