Although 1. the turntable of rotor and cylinder inner wall arranged off-centre but nontangential, holding certain distance；Because be provided with 6~
12 slide plates, it may not be necessary to separate cylinder chamber with points of tangency, after and disk diameter constant in cylinder reduces, cylinder with turn
Volume between disk just greatly increases, but its expansion-pressure ratio can then reduce, and is suitable for the expanding machine compared with low-pressure ratio.Cylinder inner wall with
The more big then volume of the relative ratio of minimum range and eccentricity increases more between turntable and expansion-pressure ratio is lower, but expansion-pressure ratio
It can also be improved by increasing the end edge azimuth of gas outlet；Another factor for influencing pressure ratio is slide plate number, slide plate
Number is more, and expansion-pressure ratio is smaller.
2. the structure of flow guiding disc is arranged in casing left side plate, by processing on flow guiding disc and air-flow can be guided by axis
To be transitioned into beveling to airfoil type curved surface import notch and outlet notch, simplify the structure of casing left side plate, and can realize
Better flow effect.
3. being provided with small air drain on wide slide plate and narrow slide plate both side surface, and it is provided on rotor by axial circular hole
With the cooling duct of the radial through-hole composition in rectangle groove, slide plate material is cooled down, the friction of slide plate and groove is reduced
Resistance improves efficiency, and prolongs its service life, and can realize oil-free lubrication, avoids Working medium pollution.
4. solving friction loss and the wear problem of cylinder and slide plate, and with rotor rotating technique using cylinder to take offence
Cylinder using right end closing left end open structure, come solve the problems, such as cylinder with turn after import and export arrangement；Due to the impact of air inlet
Power and the reaction force of exhaust all make the stress of rotor be directed toward right end, it is ensured that flow guiding disc in casing left side plate and turntable,
There is suitable gap between slide plate and cylinder of taking offence, and because being to rotate synchronously relative velocity very between turntable, slide plate and cylinder of taking offence
Small, so friction loss also very little, efficiency of expander is higher, and service life is longer；The load force being subject on slide plate is then
Do not generate axial thrust.The phenomenon that structure of multiple groups slide plate can guarantee inlet and outlet all without interruption air inlet and exhaust, makes fluid
Pulsation phenomenon is mitigated.
5. cylinder is simpler than the structure of turbo-expander with the sliding vane type expander turned, cost is relatively low；Mechanical seal is only
1 is needed, and because the pressure that it is born is outlet low pressure, so to the of less demanding of mechanical seal.
