Abstract

The invention discloses a novel high-pressure plunger piston fixed displacement pump which uses hydrodynamic pressure in a friction pair of a cylinder body and an oil distribution shaft to support the cylinder body to rotatablely load so as to perform the dynamic pressure radial oil distribution. The oil distribution shaft, a bearing and the cylinder board are sequentially arranged on a bottom plate, the cylinder body is provided with nine sets of uniformly distributed plunger piston shoe components, the upper parts of the nine sets of piston shoe components are mounted in nine holes of a retainer plate, respectively; the bearing is arranged in front of the nine sets of piston shoe components, a swash plate is arranged in front of the bearing, a flange is arranged in front of the swash plate, the bearing and a skeleton oil seal are arranged in the flange, a cover plate is arranged in front of the skeleton oil seal, a transmission shaft is arranged in the middle of a pump shell, an oil inlet A and an oil inlet B are arranged on the bottom plate, the right side of the pump shell is provided with an oil return opening C, and the oil distribution shaft is provided with an oil distribution passage D.

Description

Novel high-pressure plunger metering pump
Technical field
The present invention relates to a kind of hydraulic element, especially a kind of dynamic pressure oil film wedge effect supporting cylinder body rotation load of utilizing in cylinder body and the oil distributing shaft friction pair is carried out the novel high-pressure plunger metering pump that dynamical pressure radial is joined oil.
Background technique
At present, high-pressure plunger metering pump both domestic and external mostly adopts rigidity rolling bearing and plane hydrostatic bearing supporting cylinder body rotation load, carries out static pressure and axially joins oil, and this oil form friction factor of joining is big, makes oily temperature rise easily, reduces the volumetric efficiency of oil pump.Up to the present, also do not see a kind of hydrodynamic pressure of utilizing the dynamic pressure oil film wedge effect in cylinder body and the oil distributing shaft friction pair on the market as yet, supporting cylinder body rotation load is carried out the novel high-pressure plunger metering pump that dynamical pressure radial is joined oil.
Summary of the invention
The objective of the invention is to overcome deficiency of the prior art, a kind of hydrodynamic pressure of utilizing the dynamic pressure oil film wedge effect in cylinder body and the oil distributing shaft friction pair is provided, supporting cylinder body rotation load is carried out the novel high-pressure plunger metering pump that dynamical pressure radial is joined oil.
Technological scheme of the present invention: a kind of novel high-pressure plunger metering pump comprises base plate, oil distributing shaft, bearing, cylinder body, plunger piston slippery boots assembly, backhaul dish, bearing, swash plate, flange, bearing, outside framework oil seal, cover plate, transmission shaft, pump case, filler opening A, oil outlet B, return opening C and joins oily passage D etc.On base plate, be provided with oil distributing shaft, bearing and cylinder body in regular turn, on cylinder body, be provided with the plunger piston slippery boots assembly that nine covers are uniformly distributed with, the top of the plunger piston slippery boots assembly that nine covers are uniformly distributed with; Be installed in respectively among nine holes of backhaul dish; The plunger piston slippery boots assembly front that is uniformly distributed with at nine covers is provided with bearing, is provided with swash plate in the bearing front, is provided with flange in the swash plate front, in flange, is provided with bearing and outside framework oil seal, is provided with cover plate in the outside framework oil seal front; Transmission shaft is positioned in the middle of the pump case; On base plate, be provided with filler opening A and oil outlet B, be provided with return opening C, on oil distributing shaft, be provided with and join oily passage D on pump case the right.
Key technology of the present invention is: utilize the hydrodynamic pressure of the dynamic pressure oil film wedge effect in cylinder body and the oil distributing shaft friction pair, supporting cylinder body rotation load is carried out dynamical pressure radial and is joined oil.
