AI Technical Summary
Technical Problem
Traditional gear pumps have complex bearing side plate structures, are difficult to process, have complex assembly requirements, and have high production costs, which also affect volumetric efficiency.
Method used
The structure adopts an integral graphite bearing side plate structure, including upper and lower bearing side plates coaxial with the gear hole, combined with unloading groove and lubrication groove, which reduces the difficulty of processing and assembly, and improves reliability through the self-lubricating properties of graphite material.
Benefits of technology
It significantly improves the volumetric efficiency and reliability of gear pumps, reduces the difficulty of processing and assembly, extends service life, and uses lightweight and durable materials.
