Leakage compensation technology for gear pumps

Looking at the development of gear pumps, we can see that from the perspective of leakage compensation technology of gear pumps, the development of external meshing gear pumps has gone through the following stages: uncompensated→ Axial compensation→ The process of compensating for both axial and radial directions simultaneously. From the perspective of measures to reduce radial force, the development of gear pumps has gone through the following stages: expanding the high-pressure zone; The process of expanding the low-pressure area and utilizing radial floating compensation force to achieve force balance has significantly improved the stress situation of the gear pump and significantly extended its service life. From the development of pressure levels, the development of gear pumps has gone through low-pressure→ Medium high voltage→ The process of high pressure.
