In the current critical stage of the industrial sector's accelerated transformation towards high quality and high efficiency, hydraulic equipment, as the "power core" of various production equipment, directly affects an enterprise's production efficiency, operating costs, and market competitiveness. Faced with the higher requirements imposed by industrial production on hydraulic systems, Changjiang Hydraulic, a leading hydraulic equipment manufacturer in the industry, leveraging decades of technical accumulation in the hydraulic field and precise insight into market demands, has launched the brand-new CBGF3 Series High-Pressure Gear Pumps. With "high-efficiency output" and "stable reliability" as its two core pillars, this series of products, through the in-depth integration of advanced manufacturing processes and high-quality materials, provides strong and durable power support for industrial production in multiple fields such as auto parts manufacturing, mining, and agricultural machinery. It has become an important equipment to help enterprises break through production bottlenecks and achieve cost reduction and efficiency improvement.

The high-efficiency output of Changjiang Hydraulic's CBGF3 Series High-Pressure Gear Pumps is not a simple parameter improvement, but a comprehensive optimization of hydraulic transmission technology from the source of design. This achieves a leapfrog breakthrough in power transmission efficiency and accurately meets the urgent demand for high power density in industrial equipment.

In terms of core structural design, this series of pumps innovatively adopts a "double-arc tooth profile" design. Compared with the involute tooth profile commonly used in traditional gear pumps, the gear meshing area is significantly increased by 25%. This design effectively reduces the leakage of hydraulic oil during transportation, with the leakage rate reduced by more than 30%. At the same time, the R&D team repeatedly optimized the internal flow channel of the pump body using CFD (Computational Fluid Dynamics) simulation technology, reducing the flow resistance of hydraulic oil by 18% and minimizing energy loss during transmission. Data from third-party authoritative testing institutions shows that under the working conditions of a rated working pressure of 25MPa and a rated speed of 1500r/min, the volumetric efficiency of the CBGF3 Series High-Pressure Gear Pumps is stably above 96%, and the total efficiency is as high as 93%, which is 10%-12% higher than that of traditional gear pumps of the same type. This high-efficiency performance is transformed into a significant efficiency improvement in actual production: taking a CNC lathe equipped with this series of pumps as an example, the response speed of its spindle drive is increased by 15%, and the processing cycle of a single part is shortened by 8%. Based on an 8-hour working day, it can complete 20 more batches of part processing, increasing the enterprise's production capacity by thousands of pieces annually.

To meet the diverse power needs of different industrial scenarios, the CBGF3 Series High-Pressure Gear Pumps offer a variety of displacement specifications ranging from 10mL/r to 80mL/r. Enterprises can flexibly select the suitable model according to the load characteristics and operation intensity of their own equipment. For equipment requiring high-frequency operations such as precision machine tools and high-speed punch presses, this series of pumps has specially strengthened the shafting support structure and selected imported high-speed bearings, with a maximum speed of up to 3000r/min. Even under high-speed working conditions, it can still maintain a stable flow output, avoiding the impact of power fluctuations on processing accuracy. After a certain auto parts processing factory introduced stamping equipment equipped with the CBGF3 Series Pumps, the number of stamping times per minute of the equipment increased from 120 to 140, and the daily output of parts increased by 1500 pieces. The production efficiency has achieved a qualitative leap, effectively alleviating the production pressure during the peak order period.

The continuity and stability of industrial production determine that hydraulic equipment must have strong durability and risk resistance. In the R&D and production process of the CBGF3 Series High-Pressure Gear Pumps, Changjiang Hydraulic has always taken "stable reliability" as the core goal. Through strict material selection, precise manufacturing processes, and comprehensive quality testing, it has built three solid barriers for the stable operation of the equipment.

In terms of material selection, the key components of the CBGF3 Series High-Pressure Gear Pumps have undergone strict screening to ensure high strength, high wear resistance, and high impact resistance. The pump body and end cover are made of QT550-7 high-strength ductile iron. After professional quenching and tempering treatment, the hardness reaches HB220-250, and the compressive strength exceeds 550MPa. It can easily withstand the high-frequency vibration and impact loads generated during the operation of industrial equipment, effectively avoiding downtime caused by external damage to the pump body. The gears are made of 20CrNiMo alloy steel. After carburizing and quenching treatment, the surface hardness is as high as HRC60-62, and the core toughness is good. The wear resistance is increased by 50% compared with ordinary steel, greatly extending the service life of the gears. The seals are made of imported fluororubber material, with an oil-resistant temperature range covering -20℃ to 200℃. Even under high-pressure and high-temperature working conditions, it can still maintain stable sealing performance, effectively preventing hydraulic oil leakage. The service life of the seals can reach more than 8000 hours, which is twice that of ordinary seals, reducing the maintenance cost caused by seal failure.

The precision of the manufacturing process directly affects the stability of the product. Changjiang Hydraulic has introduced a German Siemens five-axis linkage machining center to perform precision machining on core components such as gears and shafts. The cumulative error of gear tooth pitch is strictly controlled within 0.005mm, and the radial runout of the gear does not exceed 0.003mm. This ensures the accuracy of gear meshing, reduces noise and wear during operation, and makes the pump body run more smoothly. Before leaving the factory, each CBGF3 Series High-Pressure Gear Pump must undergo a "triple strict test": a 72-hour continuous load test to simulate the full-load operation of industrial equipment and comprehensively inspect the performance stability of the pump body; a high-low temperature cycle test (-30℃ to 120℃) to verify the adaptability of the pump in extreme temperature environments and ensure normal operation in cold areas or high-temperature workshops; and a vibration and impact test (frequency 20-2000Hz, acceleration 10g) to ensure the reliability of the pump in the vibration environment of heavy equipment. After a certain heavy machinery manufacturer applied the CBGF3 Series Pumps to the hydraulic system of loaders, the equipment operated continuously for 6 months without failure. The failure rate of the hydraulic system was reduced by 60% compared with other brand pumps used before, effectively avoiding production losses caused by equipment downtime and saving a large amount of maintenance costs and downtime costs for the enterprise.

With the dual advantages of high efficiency and stable reliability, Changjiang Hydraulic's CBGF3 Series High-Pressure Gear Pumps have successfully penetrated into multiple industrial fields, providing customized power solutions for production needs in different scenarios, and helping enterprises significantly reduce operating costs while improving efficiency.

In the field of auto parts manufacturing, this series of pumps is suitable for the hydraulic drive systems of equipment such as CNC lathes and machining centers. After a certain automobile transmission production enterprise introduced the CBGF3 Series Pumps, the energy consumption of the equipment's hydraulic system was reduced by 13%. Based on the annual power consumption, it can save more than 80,000 yuan in electricity expenses every year. At the same time, the stable performance of the pump body significantly reduces the number of equipment maintenance times. The maintenance cycle is extended from the original 3 months to 6 months, and the annual maintenance cost is reduced by 45%. In the field of mining equipment, the maximum working pressure of the CBGF3 Series Pumps can reach 31.5MPa, and it has excellent anti-pollution ability, perfectly adapting to the hydraulic systems of mining crushers, conveyor belts and other equipment. After a certain mining enterprise applied it to the crusher, the crushing efficiency of the equipment was increased by 18%, and the crushing cost per ton of ore was reduced by 0.5 yuan. Based on the annual ore processing capacity of 1 million tons, it can save 500,000 yuan in costs every year. In addition, the anti-pollution design of the pump body extends the hydraulic oil replacement cycle to 12 months, which shortens the oil change frequency by 50% compared with traditional pumps, further reducing maintenance costs and resource consumption. In the field of agricultural machinery, the low-temperature resistance and lightweight design of this series of pumps are suitable for the hydraulic systems of tractors, harvesters and other equipment. After being adopted by a certain agricultural machinery manufacturer, the starting success rate of the tractor in a low-temperature environment of -25℃ reaches 100%, and the operation reliability is significantly improved. At the same time, the weight of the pump body is reduced by 15% compared with similar products, which helps to reduce the overall energy consumption of agricultural machinery and improve the operation endurance.

At a time when the industrial sector has an increasingly urgent demand for high-quality and high-efficiency hydraulic equipment, the launch of Changjiang Hydraulic's CBGF3 Series High-Pressure Gear Pumps is not only a manifestation of the enterprise's technical strength and quality persistence, but also an accurate response to the power needs of industrial production. In the future, Changjiang Hydraulic will continue to focus on technological innovation, continuously optimize product performance, expand application scenarios, provide better hydraulic solutions for more industries, and help industrial manufacturing move towards a new stage of higher efficiency and more sustainable development.
