The utility model is composed of a power piston, a gas distribution piston and a straight line generator, wherein, the gas distribution piston is driven by an electromagnetic drive member, and a side surface thereof is connected with a cylinder wall through a section of a pressure gas cushion. Actions are more flexible and accurate. The utility model can conveniently regulate the movement of the gas distribution piston to control a cycle process so that the cycle process can more easily approach an ideal cycle.
Description
Technical field:
The utility model relates to a kind of external-burning engine by the Stirling periodic duty, particularly a kind of stirling generator group by the work of driven by power gas distribution piston.
Background technology:
Traditional Stirling engine, mostly move by mechanical transmission mechanism drive gas distribution piston and finish Stirling circulation (CN1217765A) by an inertia system, its maximum shortcoming is that the real work circulation departs from Ideal Cycle, need turn round under the condition of HTHP, this has brought the problem of sealing difficulty again.CN2315306Y discloses the scheme that a kind of elasticity switching mechanism drives the gas distribution piston motion, make the real work recycle ratio near Ideal Cycle, but also exist actual cycle to be subjected to the influence of spring parameter, be difficult for adjusting, there is its side force to be difficult to balance again, when particularly piston is in the spring upturned position, can increases because of side force causes the friction of gas distribution piston and casing wall more greatly, influence the motion of piston, and can increase wearing and tearing because of friction.
Summary of the invention:
The purpose of this utility model is that design a kind ofly can be controlled and adjust cyclic process easily, be easier near Ideal Cycle, and its gas distribution piston is very little with the casing wall friction, can be accurately, the external combustion generating set that moves flexibly.
It is the same with traditional Stirling engine that the purpose of this utility model is achieved in that, dynamic piston and gas distribution piston in the cylinder body, but not to link to each other between the two with mechanical transmission mechanism, but only be electrically connected, be that power piston drives a straight line generator, the voltage that generator produces is delivered to a control circuit, control circuit is according to the phase place of this voltage, the requirement of waveform and Stirling circulation produces the required voltage ripple, be added to the electromagnetic drive that connects together with gas distribution piston, drive the gas distribution piston motion, the side of gas distribution piston joins by the air cushion and the cylinder body of one deck book book.Like this, by regulating the parameter of control circuit, can adjust the motion state of gas distribution piston artificially at any time, thereby obtain even more ideal thermodynamic cycle as required, also because the gap between piston side wall and cylinder body is a stressor layer air cushion, it is little to rub, and makes the gas distribution piston flexible movements, has good servo-actuated performance, guarantee the accurate of its action, and be beneficial to the raising in life-span again.
Said electromagnetic drive, it is an electromagnetic power mechanism of being fixed in cylinder body, be moving-coil type, or ferromagnetic formula or other structural shapes that is suitable for, by support, an end face of connecting rod and gas distribution piston fixes its coil as movable part (or unshakable in one's determination), according to the direction and the size of input current, do reciprocating linear motion, drive gas distribution piston and do identical motion.Said book stressor layer air cushion is that one deck is centered around the filling of piston side and is flowing in the Working medium gas in the gap between piston and the cylinder body, gas is from being positioned between cylinder body and shell or a pressure gas dome of other appropriate locations, the latter enters the position, stage casing in piston and cylinder body gap by tubule and the aperture that is symmetrically distributed on the cylinder circumference four (or greater than four even number), and the low temperature air chamber of cylinder (or the additional little pump of calming the anger) is connected in the pressure gas dome by Non-return air valve and wireway, when the low temperature air chamber pressure is the highest gas is compressed into the pressure gas dome in each circulation.It serves as square wave, the sawtooth waveforms combined waveform generator of ginseng Test voltage with the linear electric generator output voltage that said control circuit is one, can regulate the interlock circuit parameter according to the needs of circulation and obtain required square wave and the output of sawtooth waveforms combined waveform.In view of this type of circuit has numerous known technologies, do not describe in detail at this.Said linear electric generator is that winding, magnet and iron core are made stator, makes the linear electric generator of ticker by magnet or movable core, the known linear electric generator that also can use other to be suitable for.Said Non-return air valve is movable flap membrane type Non-return air valve or elastic membrane Non-return air valve or other Non-return air valves that is suitable for.
