Vertical dimension between the lower surface of seat is 9.8mm～10mm.
The beneficial effects of the utility model are：
Above-mentioned Rotary Compressor, enhances first compressor start, reduces compressor start voltage.Compressor is being opened
Dynamic moment rotor can be subject to the side force that stator is produced to it, and because upper bracket axle journal lengthens 4mm～11mm, undersetting axle journal is lengthened
4mm～6mm, the torque of cylinder lower end balanced side force increases, and side force is preferably balanced, and compressor start strengthens, and opens
The low about 10V～15V of galvanic electricity pressure drop.
Next to that reducing power transmission shaft circular runout, strengthen compressor start and improve compressor efficiency.Prop up on compressor
Seat is lengthened with undersetting axle journal, and is to coordinate pressing design rotor to be fixed with pumping pressing depth because upper bracket upper end lengthens
Value, rotor has newly been designed as hole countersunk, has hole countersunk rotor compared with without the mitigation of counterbore rotor weight.Therefore bent axle operation is more steady
Fixed, Axial and radial bounce reduces, and the stable friction and between stator of bent axle rotor driven reduces, compressor start torque with rub because
Number is directly proportional, and startability is significantly improved.Friction loss between rotor and stator is reduced, and compressor enters power reduction, and rotor turns
Speed increases, and the Energy Efficiency Ratio of compressor is improved therewith.
