In the field of marine and offshore engineering, a stable and reliable power transmission system is crucial to ensuring the smooth progress of various operations. As a key power source of the hydraulic system, the performance of the gear pump directly affects the operating efficiency and safety of the entire equipment. Relying on decades of in - depth cultivation in the hydraulic field, Changjiang Hydraulic has developed and launched the CBK1025 - B4FL gear pump. With its excellent reliability, stability and outstanding performance, this gear pump has become a preferred product in the marine and offshore engineering sector. It is widely used in scenarios such as commercial shipping, offshore platforms and fishing vessels, providing strong and stable power support for various marine operations and boosting the efficient development of the marine economy.

From the perspective of technical characteristics, the Changjiang Hydraulic CBK1025 - B4FL gear pump integrates a number of advanced technologies in its design and manufacturing, laying a solid foundation for its excellent performance. This gear pump adopts a high - precision gear processing technology, with the tooth profile error of the gears controlled at the micron level. This effectively reduces the friction loss during the gear meshing process. Not only does it improve the volumetric efficiency of the hydraulic pump, keeping it stable above 90%, but it also greatly extends the service life of the gears.

At the same time, the pump body of the gear pump is made of high - strength cast iron material. After a special heat treatment process, its tensile strength and wear resistance are significantly improved. It can withstand harsh working conditions such as high pressure and vibration that are common in marine and offshore engineering operations, ensuring that it is not prone to deformation or damage during long - term operation.

In terms of the design of sealing performance, the CBK1025 - B4FL gear pump adopts a double - seal structure. The main seal is made of nitrile rubber material that is oil - resistant and seawater - corrosion - resistant, and the auxiliary seal uses polytetrafluoroethylene material. This double protection effectively prevents the leakage of hydraulic oil and the entry of seawater and impurities into the pump body. Even in the marine environment with high salt spray and high humidity, it can maintain a good sealing effect, avoid equipment failures caused by seal failure, and significantly improve the adaptability and reliability of the gear pump in the marine environment. In addition, this gear pump is also equipped with an efficient filtering device, which can finely filter the hydraulic oil entering the pump body. The filtration accuracy can reach 10 microns, effectively removing impurities in the hydraulic oil, preventing the impurities from causing wear to key components such as gears and bearings, and further ensuring the stable operation of the gear pump.

In terms of application advantages, the Changjiang Hydraulic CBK1025 - B4FL gear pump shows strong adaptability and practical value in response to the diverse needs of marine and offshore engineering. In the field of commercial shipping, whether it is a large container ship or a bulk carrier, its deck machinery, steering gear system and cargo handling equipment all need stable hydraulic power support. The CBK1025 - B4FL gear pump can provide continuous and stable power output for these equipments. Its rated working pressure can reach 25MPa, and the maximum flow rate is 25L/min. It can flexibly adjust the output according to the actual working conditions of the equipment, ensuring the efficient progress of lifting and loading - unloading operations of the deck machinery, and the precise control of the course by the steering gear system, thus improving the operating efficiency and navigation safety of commercial shipping.

In the field of offshore platforms, the CBK1025 - B4FL gear pump also plays an important role. The drilling equipment, well cementing equipment and marine observation instruments on offshore platforms have extremely high requirements for the reliability and stability of hydraulic pumps. This gear pump can maintain stable operation under the working conditions where the offshore platform is in a bumpy and inclined state for a long time. Its anti - vibration performance meets the relevant standards of offshore platform equipment, and it can withstand vibration loads with a frequency of 10 - 50Hz and an amplitude of 0.1 - 0.5mm. This ensures that key operations such as drilling and well cementing are not affected by equipment vibration, and guarantees the normal production and operation of the offshore platform.

For fishing vessels, the advantages of the CBK1025 - B4FL gear pump are also very obvious. The net - hauling machines and fishing machinery on fishing vessels need to start and stop frequently, which puts forward high requirements for the response speed and durability of the hydraulic pump. This gear pump has the characteristics of quick start and stable operation, and can quickly adapt to the changes in the working conditions of fishing machinery. It is not prone to failures during frequent start - stop processes. At the same time, it has a compact structure and a small size, which is convenient for installation and arrangement on fishing vessels with limited space. It provides convenient and reliable power support for fishing production, helping fishermen improve fishing efficiency and reduce equipment maintenance costs.

User feedback is an important basis for verifying product performance. Since it was put on the market, the Changjiang Hydraulic CBK1025 - B4FL gear pump has won the recognition and praise of many users with its excellent performance. A large ocean - going shipping company installed the CBK1025 - B4FL gear pumps on 20 container ships under its flag. After two years of actual operation, the company's feedback showed that the failure rate of the deck machinery and steering gear system on the cargo ships decreased by 70% compared with that of other brand gear pumps used before, and the maintenance cycle of the equipment was doubled. This not only reduced the shipping delays caused by equipment failures, but also lowered the maintenance costs, creating significant economic benefits for the company.

An offshore engineering company adopted the CBK1025 - B4FL gear pump in the offshore drilling platform it constructed. The technical director of the company said that during the one - year drilling operation of the platform, the CBK1025 - B4FL gear pump always maintained stable operation without any problems such as seal leakage or insufficient power. Its reliable performance provided a strong guarantee for the smooth progress of the drilling operation. In addition, the professional after - sales service team of Changjiang Hydraulic has also received high praise from users. When users encounter problems in equipment installation, commissioning or maintenance, the after - sales service personnel can arrive at the site to provide support within 48 hours, ensuring that the problems are solved in a timely manner and minimizing the equipment downtime.

With the continuous development of the global marine economy, the performance requirements for hydraulic equipment in the marine and offshore engineering field will be further improved, and intelligence and energy conservation have become important trends in the development of the industry. Changjiang Hydraulic will continue to increase R & D investment. On the basis of the CBK1025 - B4FL gear pump, it will further optimize the energy - saving performance of the product, explore the integration of intelligent monitoring technology, realize real - time monitoring of the operating status of the gear pump and fault early warning, and provide users with more intelligent and efficient hydraulic solutions. In the future, the Changjiang Hydraulic CBK1025 - B4FL gear pump will continue to play an important role in the marine and offshore engineering field, contribute more to promoting the high - quality development of the marine economy, and provide more reliable and high - quality hydraulic products and services for global users.
