In the intricate ecosystem of construction machinery, the hydraulic system serves as the "muscle," and at the heart of this system lies the gear pump—a critical component responsible for converting mechanical energy into hydraulic energy. Its performance directly dictates the operational efficiency, stability, and service life of the entire machinery. As China’s infrastructure, mining, and municipal engineering sectors continue to expand, the demand for high-performance, reliable, and adaptable gear pumps has never been greater. Against this backdrop, Changjiang Hydraulics, a benchmark enterprise in China’s hydraulic industry, has emerged as a pioneer with its CBY3063-1FL Gear Pump. This product, born from decades of technical expertise and in-depth industry insights, has quickly established itself as a preferred choice for construction machinery such as excavators, loaders, road rollers, and forklifts, delivering stable and efficient hydraulic power to drive high-quality engineering operations.

Construction machinery relies heavily on continuous and efficient power supply from the hydraulic system to perform a wide range of tasks—from lifting materials with loaders and excavating with excavators to transporting goods with forklifts. The CBY3063-1FL Gear Pump by Changjiang Hydraulics has achieved a breakthrough in power transmission efficiency through its optimized gear meshing structure and high-precision tooth processing technology. This design significantly reduces energy loss during gear meshing, resulting in a volumetric efficiency of over 90%, ensuring the efficient conversion of hydraulic energy to mechanical energy.

Compared to traditional gear pumps, the CBY3063-1FL stands out by scientifically matching gear modules and the number of teeth. This allows it to deliver a larger flow of hydraulic oil at the same rotational speed, providing robust power support to the equipment. Take a 5-ton loader as an example: after being equipped with this gear pump, the response speed of the lifting mechanism is increased by more than 15%, shortening the time for a single material lifting operation. This not only reduces the operation cycle but also significantly improves the overall work efficiency of the machine. In the case of small excavators, the stable flow output of the CBY3063-1FL ensures the smooth and coherent movement of the boom, stick, and bucket. Even under heavy-duty excavation conditions, it avoids movement lag caused by insufficient power, guaranteeing the efficient progress of excavation work.

Furthermore, the gear pump boasts excellent pressure stability. Its built-in pressure regulation device can adjust the output pressure in real-time according to changes in the equipment’s operating load. This not only prevents system overload caused by sudden load increases but also reduces power waste. When a road roller is used for road compaction, this pressure adaptive function ensures that the roller always maintains a stable pressure output. It not only guarantees that the road compaction density meets engineering standards but also effectively protects the hydraulic system components, extending the overall service life of the equipment.

Construction machinery often operates in harsh environments characterized by dust, mud, vibration, and temperature fluctuations. These conditions place strict demands on the material strength, wear resistance, and sealing performance of gear pumps. When developing the CBY3063-1FL Gear Pump, Changjiang Hydraulics comprehensively enhanced the product’s durability and reliability from the selection of core component materials to the control of production processes, ensuring its long-term stable operation under complex working conditions.

In terms of core component materials, the driving gear and driven gear of the CBY3063-1FL Gear Pump are made of 20CrMnTi high-strength alloy steel. After undergoing multiple precision processing procedures such as carburizing and quenching, and fine grinding, the tooth surface hardness reaches HRC58-62. This greatly improves the wear resistance and impact resistance of the gears. Even under long-term high-load operation, it can effectively avoid problems such as tooth surface wear and pitting. The pump body and end cover are made of high-strength aluminum alloy materials, which not only ensure structural rigidity but also reduce the product weight, facilitating equipment integration and installation.

Sealing performance is crucial for ensuring the stable operation of the gear pump. The CBY3063-1FL Gear Pump adopts imported double-lip skeleton oil seals and high-precision O-rings, combined with an optimized seal groove structure design. This effectively prevents hydraulic oil leakage and resists the entry of external dust and impurities into the pump body. In mining operations with high dust concentrations, this sealing structure can maintain good sealing performance for a long time, avoiding internal wear of the pump body caused by impurity intrusion and ensuring the long-term stable operation of the gear pump. In addition, the pump body is equipped with an efficient lubrication system that can form an oil film in real-time during gear operation, reducing gear meshing friction, minimizing component wear, and further extending the product’s service life.

Construction machinery operates in a wide range of environments—from open-air construction sites exposed to high-temperature sunlight to high-altitude areas with low temperatures, from muddy and humid municipal foundation pits to dusty mining sites. These diverse and harsh conditions place extremely high demands on the environmental adaptability of gear pumps. Through comprehensive structural optimization and performance testing, the CBY3063-1FL Gear Pump by Changjiang Hydraulics has acquired strong environmental adaptability, enabling it to operate stably and reliably under various harsh conditions.

In terms of temperature adaptability, the CBY3063-1FL Gear Pump has undergone special low-temperature startup optimization design. It can start smoothly even in a low-temperature environment of -30°C, avoiding startup difficulties caused by increased oil viscosity. At the same time, the pump body uses high-temperature resistant sealing materials and lubricating grease, which can maintain good sealing performance and lubrication effect even in a high-temperature environment of 80°C. This effectively prevents problems such as high-temperature deterioration of hydraulic oil and aging of seals. Whether in road construction in cold northern regions or infrastructure projects in hot southern areas, this gear pump can perform stably.

To cope with vibration and impact working conditions, the CBY3063-1FL Gear Pump adopts a reinforced pump body structure design. By increasing the pump body wall thickness and optimizing the connection method of internal parts, the overall anti-vibration capability is enhanced. Meanwhile, the interference fit process is used for the cooperation between the gear and the shaft, ensuring that the parts are firmly connected under strong vibration and avoiding problems such as loosening and displacement. During the high-frequency vibration compaction operation of road rollers or when excavators are digging hard rocks, this structural design can effectively buffer vibration and impact, protect the internal components of the pump body, and ensure the stable operation of the gear pump. In addition, the pump body inlet is equipped with a high-precision oil suction filter, which can filter out impurity particles in the hydraulic oil, prevent pollutants from entering the pump body and causing failures, and further improve the product’s reliability in complex environments.
