Start-up course:
Press enable switch 58, relay 59 gets electric, and one-level suction valve 15 is opened; When this moment, bent axle 4 corners were in the scope of 0-180 degree; One-level exhaust valve 16 is in closed condition, and then first stage piston 6 moves downward under the pressure of pressurized gas, drives one-level connecting rod 7 promotion bent axles 4 and is rotated in the forward.When bent axle 4 corners equal 180 when spending, one-level exhaust valve 16 is opened, and secondary exhaust valve 23 cuts out; One-level cylinder 5 is communicated with secondary cylinder 8; The cylinder internal air pressure equates, because the lifting surface area of second piston 9 big than first stage piston 6, second piston 9 can move downward; First stage piston 6 moves upward, and drive one-level connecting rod 7, secondary connecting rod 10 promote bent axles 4 to be continued to be rotated in the forward.When bent axle 4 corners equal 360 when spending, one-level exhaust valve 16 cuts out, and secondary exhaust valve 23 is opened; Secondary cylinder 8 is communicated with three-stage cylinder 11, because three grades of pistons 12 are stressed bigger than second piston 9, first stage piston 6, three grades of pistons 12 can move downward; Second piston 9 moves upward; Drive one-level connecting rod 7, secondary connecting rod 10 and three grades of connecting rods 13 promotion bent axles 4 and continue to be rotated in the forward, so move in circles, then motor is accomplished the forward startup.
When pressing enable switch 58, if bent axle 4 corners are in the scope of 180-360 degree at this moment, one-level exhaust valve 16 is in open mode; Secondary exhaust valve 23 is in closed condition, and one-level cylinder 5 is communicated with secondary cylinder 8, and the cylinder internal air pressure equates; Because the lifting surface area of second piston 9 is bigger than first stage piston 6; Second piston 9 can move downward, and first stage piston 6 moves upward, and one-level connecting rod 7 drives bent axle 4 with secondary connecting rod 10 and is rotated in the forward.When bent axle 4 corners equal 360 when spending, one-level exhaust valve 16 cuts out, and secondary exhaust valve 23 is opened; Secondary cylinder 8 is communicated with three-stage cylinder 11, because three grades of pistons 12 are stressed bigger than second piston 9, first stage piston 6, three grades of pistons 12 can move downward; Second piston 9 moves upward; One-level connecting rod 7, secondary connecting rod 10 and three grades of connecting rods 13 drive bent axle 4 to be continued to be rotated in the forward, and so moves in circles, and then motor is accomplished the forward startup.
Visible by above process, this motor does not need external force to start voluntarily, and can keep specific sense of rotation.
Run well:
Behind engine start; Unclamp enable switch 58, if in the moment of unclamping, the salient point of crank position cam 2 38 has turned over peak; And the salient point of crank position cam 3 39 does not also touch suction valve off switch 47; Then JK flip-flop 61 is exported high level, relay 59 adhesive still, and one-level suction valve 15 stays open state.When the salient point of crank position cam 3 39 touches suction valve off switch 47, JK flip-flop 61 output low levels, relay 59 dead electricity; One-level suction valve 15 cuts out; Intake process finishes, and the gas that has got in the one-level cylinder 5 expands, and continues to promote first stage piston 6 and continues to move downward.When first stage piston 6 ran to lower dead center, one-level exhaust valve 16 was opened, and the gas in the one-level cylinder 5 gets into secondary cylinder 8 to be continued to expand, and first stage piston 6 moves upward, and second piston 9 moves downward.When first stage piston 6 runs to top dead center, touch one-level inlet open switch 45, JK flip-flop 61 output high level, one-level suction valve 15 is opened, and gets into new round intake process, so reciprocation cycle.
When the moment of unclamping enable switch 58, the salient point of crank position cam 3 39 had touched suction valve off switch 47, and the salient point of crank position cam 2 38 does not also forward peak to; Then one-level suction valve 15 cuts out, and the gas that has got in the one-level cylinder 5 continues to expand, when first stage piston 6 runs to top dead center; Touch one-level inlet open switch 45, JK flip-flop 61 output high level, one-level suction valve 15 is opened; Get into new round intake process, so reciprocation cycle.
The sequential chart of one-level inlet open switch 45, suction valve off switch 47, AND circuit 60, JK flip-flop 61 outputs is as shown in Figure 6.Visible by figure, the suction pulsation width is decided by the position of one-level inlet open switch 45, suction valve off switch 47, and air inlet variable control mode in correct time can be realized in the position of by-pass cock.
After enable switch 58 unclamped, feedback loop got into working state, when three grades of pistons 12 run to lower dead center; Crank position cam 1 is connected sampling switch 44, and cylinder pressure sensor 51 is gathered cylinder three internal pressures, after holding circuit 52 keeps; The ambient pressure signal of gathering with the ambient pressure sensor 53 that is placed in the ambient air is amplified into power amplifier 55 through signal amplifier 54, carries out power amplification rear driving actuating motor 42 through power amplifier 55 and drives worm screw 41 rotations, and terminal pressure is higher than ambient pressure if cylinder three expands; Then actuating motor 42 is just changeing and drives worm gear 40 and be rotated counterclockwise, and makes on the suction valve off switch 47 and moves, and suction valve cuts out in advance; Air inflow reduces, thereby tail gas pressure is reduced, and terminal pressure is lower than ambient pressure if cylinder three expands; Then actuating motor 42 counter-rotating drive worm gears 40 turn clockwise, and suction valve off switch 47 is moved down, and suction valve is lagged behind close; Air inflow increases; Thereby tail gas pressure is risen,, make the tail gas pressure stability in the accurate scope that equates with ambient pressure through closed loop control.Flow control valve 3 can change the output power of motor through the adjusting air inflow.
Along with pressure in the gas holder 1 reduces; Suction valve off switch 47 will move down gradually, and the suction pulsation width increases gradually, when suction valve off switch 47 moves down into minimum point; Move to peak on the baffle plate 43; Touch single-pole double-throw switch (SPDT) 1, single-pole double-throw switch (SPDT) 2 49,50 actions of gas circuit diverter switch, make secondary suction valve 22, secondary inlet open switch 46 put in circuit, Solenoid ball valve 1, Solenoid ball valve 3 20 change cut-off state into by on state simultaneously; Solenoid ball valve 2 18, Solenoid ball valve 4 21 change on state into by cut-off state; Thereby realize the gas circuit switching, one-level cylinder 5 excised that pressurized air continues to expand from gas circuit in secondary cylinder 8 and three-stage cylinder 11 series loops.After gas circuit was switched, tail gas pressure can rise suddenly, and worm gear 40 is rotated counterclockwise, and through closed loop control, makes the tail gas pressure stability in the accurate scope that equates with ambient pressure, and suction valve off switch 47 can move to the correct position in below, left side.Along with pressure in the gas holder 1 further reduces, move in 47 meetings gradually of suction valve off switch, pressure is reduced to 0.4Mpa in gas holder 1, and inflation process finishes, and needs refill pressurized air to gas holder 1.
The present invention not only can be as the motor of Pneumatic automobile; Can also replace various gas motors to realize energy saving purposes; Also can be used for the Caes system, be used for being electric power system peak-clipping and valley-filling or supporting, solve the intermittent bottleneck of wind-power electricity generation with wind power system.
