Detailed description of the invention
Below in conjunction with Figure of description and embodiment, the detailed description of the invention of the present invention is described in further detail:
With reference to a kind of direct connection piston motor type gas-booster shown in Fig. 2, including power cylinder 6, power piston 8, connecting rod
10, compression cylinder 7, compression piston 9 and throttle adjustment device 11, one end of described connecting rod 10 is with described power piston 8 even
Connect；The other end of described connecting rod 10 is connected with described compression piston 9；Described pressurized cylinder is by a left side for described pressurized cylinder
End face is connected with the right side of described power cylinder 6；The central part of the left side of described power cylinder 6 is provided with igniter 601；
The right side of described power cylinder 6 is provided with connecting rod 10 and passes through hole；It is respectively equipped with fuel air on the sidewall of described power cylinder 6
Mouth 603 and exhaust vent 602；It is provided with air throttle at described fuel air mouth 603；The inside of described compression cylinder 7 is provided with
Air chamber barricade 704；The inner space of described compression cylinder 7 is divided into compression chamber and air distribution cavity by described air chamber barricade 704；Institute
The outer wall on the right side of the compression chamber stated is provided with compressed gas air inlet 702 and compressed gas air vent 701；Described compressed gas
It is equipped with check valve at body air inlet 702 and described compressed gas air vent 701；On the outer wall in the left side of described compression chamber
It is provided with the first air distribution hole 703；The outer wall of described air distribution cavity is provided with the second air distribution hole 705；The left side of described compression cylinder 7
It is equipped with connecting rod with the central part of described air chamber barricade 704 and passes through hole；The left side of described compression cylinder 7 and described air chamber
The connecting rod of the central part of barricade 704 is by being mounted on sealing ring on the inwall in hole；Described throttle adjustment device 11 is installed
On described power cylinder 6 right side；The throttle adjustment device 11 that institute's end is stated includes inputting connecting rod, output connecting rod and reset bullet
Spring；Described input connecting rod extends to the inside of described power cylinder 6；Described input connecting rod is by described back-moving spring
It is connected with the outer wall of described power cylinder 6.
The technical solution adopted for the present invention to solve the technical problems is: power piston 8 and compression piston 9 direct connection, saves
Linear motion is converted to rotary motion in the intermediate link being converted to linear motion；When equipment starts running, compression piston
Place 9 is at right dead-centre position, and pressure is that P1 natural gas enters compression cylinder 7, the instantaneous end at compression piston 9 from compressed gas air inlet
Produce the thrust of P1 × S1 size on the S1 of face, promote compression piston 9 to be moved to the left, simultaneously drive power piston 8 and be moved to the left, dynamic
The ignition system fires when mixed gas of air and natural gas is compressed to a certain degree in power cylinder 6, combustion gas explosive force makes power
Piston 8 moves to right, and in compression cylinder 7, the gas compression of P1 pressure is discharged after P2, meanwhile, carries out scavenging process in power cylinder 6, to only
I.e. starting next circulation after Dian, such unit Automatic continuous runs.
The direct connection piston several key problem in technology of motor type gas-booster:
Product P1 × the S1 of the admission pressure P1 of compressed gas and the area S1 of compression piston 9 have to be larger than fuel gas pressure
Product P0 × the S2 of the area S2 of P0 and power piston 8, such piston have after a stroke terminates enough reverberation matrix method P1 ×
S1-P0 × S2, is used for overcoming the frictional resistance of piston component and ensureing the compression ratio of power cylinder 6.
The regulation of the power of power cylinder 6, i.e. controls the air-fuel ratio of power cylinder 6, typically 15: 1～18: 1, regulates air throttle
The aperture i.e. power of scalable power cylinder 6；From contraction principle, it is compressed to temperature T2, pressure from intake air temperature T1, pressure P1
P2, piston range is k, and the time used by circulation primary is t, corresponding maximum compression merit be W=kS1 × (P2-P1) ×
(P1T2-P2T1)/P2T1, can be come power cylinder 6 type selecting by 1.2W/t.
When admission pressure is in 2.5～7.5MPa, two flows and the good units connected in series of power ratio is used to become 2 grades of compressions
, when pressure >=7.5～10MPa, use a unit.
Present configuration simple in construction, it is possible to reduce manufacturing cost, the economic benefit that raising natural gas is gathered, meanwhile, if
The reduction of standby size and weight is more suitable for the requirement that equipment is frequently moved.
The above, be only presently preferred embodiments of the present invention, and not the technical scope to the present invention makes any limit
System, therefore every any trickle amendment, equivalent variations and modification above example made according to the technical spirit of the present invention, all
Still fall within the range of technical scheme.
