ChangJia Hydraulic Gear Pump Customization Case

01.  Customer's Original Product Situation

A customer was using a traditional bushing in their gear pump, which had limitations in performance matching and structural design during long - term operation. The old - style bushing, as shown in the picture, had a relatively simple internal flow - guiding structure, which affected the overall efficiency of the gear pump in complex working conditions.

02. Customer's Customization Requirement

The customer put forward a new structural requirement for the bushing. They hoped to optimize the internal flow - guiding part of the bushing to improve the fluid flow characteristics inside the gear pump, reduce energy loss, and enhance the pump's adaptability to high - pressure and high - speed working conditions. As can be seen from the comparison picture, the new - style bushing to be modified has a more sophisticated internal structure design.

03. ChangJia's Customized Solution and Confirmation

ChangJia, as a global leader in hydraulic technology, integrating R&D, manufacturing, sales, and service, leveraged its strong technical strength. Rooted in Bosch Rexroth's core technologies and integrating advanced equipment and processes from Germany, Switzerland, Japan, the UK and other countries, our technical team re - designed the bushing according to the customer's needs.

The design fully considered the fluid mechanics principles and the actual working conditions of the gear pump. After precise calculations and simulations, a new bushing structure was determined, and the design drawings were provided to the customer in a timely manner. The customer highly recognized ChangJia's professional design ability and the rationality of the solution, and confirmed the customized design.
