Problems solved by technology
Although this method can solve the sealing of the pump shaft in a short time to a certain extent, because the low-pressure injection gear pump works in high temperature (230 ℃), high pressure (6-8Mpa), high viscosity (5000-8000CPS) glue In the harsh environment without fluid and no lubrication, the seal of the pump shaft will fail quickly, resulting in glue seepage and glue leakage

The invention discloses a seal structure of a low-pressure jet molding special gear pump torque input shaft, which comprises a gear pump and a spring energy storage seal ring, wherein the gear pump comprises a first gear pump sheet, a second gear pump sheet and a third gear pump sheet; a gear is arranged in the second gear pump sheet; a gear pump torque input shaft and a gear short shaft are arranged in the gear pump; the spring energy storage seal ring is arranged on the gear pump torque input shaft; a pump shaft end cover is arranged at one end of the gear pump through the gear pump torque input shaft; the spring energy storage seal ring, the gear pump torque input shaft and the pump shaft end cover are fixed in a matching manner; a bottom sub is arranged at one end of the gear short shaft. The seal structure of the low-pressure jet molding special gear pump torque input shaft provided by the invention is made of the polytetrafluoroethylene composite material, has the excellent sealing effect through simultaneous various seal, is wear resistant and has long service life.
Description
technical field [0001] The invention relates to the field of packaging and protection of gear pumps, in particular to a sealing structure for a torque input shaft of a gear pump dedicated to low-pressure injection molding. Background technique [0002] The sealing of the torque input shaft of the existing low-pressure injection-molding special gear pump is mostly solved by the combination of a garden cone seal ring and an additional spring. Although this method can solve the sealing of the pump shaft in a short time to a certain extent, because the low-pressure injection gear pump works in high temperature (230 ℃), high pressure (6-8Mpa), high viscosity (5000-8000CPS) glue In the harsh environment without fluid and no lubrication, the seal of the pump shaft will quickly fail, resulting in glue seepage and glue leakage. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a sealing structure for the torque input shaf...
