Description
Technical field
The utility model is related to a kind of vane pump, more particularly to a kind of lower housing of vane pump.
Background technology
The operation principle of vane pump：Motor drives rotor rotation by transmission shaft, work of the blade on rotor in centrifugal force
It is slid in and out in blade groove under, so that the outer end of blade is pressed on the inner surface of stator, seal, while by oil suction
Chamber and oil-discharging cavity separate, with being rotated further for rotor, when blade is moved from the small arc-shaped area of stator inner surface to orthodrome area
When, two volumes sealed between blades increase, and just pass through the inlet port oil suction on side plate；When blade is from the big of stator inner surface
When circular arc area is moved to small arc-shaped area, the volumes between two sealing blades become smaller, by the press oil port oil extraction on side plate, when turning
Sub- each rotation, blade is reciprocal in slot to be completed to inhale twice, oil extraction process twice, therefore also known as double-acting vane pump.Hydraulic oil quilt
Push the oil outlet end of the pump housing to, hydraulic oil is generated high pressure by continued compression, and the height of the outlet end high pressure oil and blade inner end pumped
Pressure chamber communicates, and the hydraulic oil of high pressure pushes blade to be pressed on stator inner surface, keeps blade de- with stator inner surface
It is empty, it is ensured that high pressure oil continues to export outward by the oil outlet of the pump housing.Vane pump is typically to be made of upper and lower two shells, existing rank
Section vane pump lower housing there are the drawbacks of be it is complicated, processing get up to be more troublesome and inconvenient, leakproofness is installed
Energy is poor, oil yield efficiency is low etc..
