ECU3 matches the rated power of the first operating mode at this time so that the maximum power of diesel engine 2 is maintained at the rated power of the first operating mode；
When power adjustment switch 8 is in the second gear, when movable contact 400 and the second stationary contact 202 contact, second resistance in convertor circuit
200 and 3rd resistor 300 to convertor circuit carry out simultaneously divide so that current value is placed in the middle in circuit, at this time ECU3 match second
The rated power of operating mode so that the maximum power of diesel engine 2 is maintained at the rated power of the second operating mode；At power adjustment switch 8
When third gear, when movable contact 400 and third stationary contact 301 contact, in convertor circuit 3rd resistor 300 to convertor circuit into
It goes while dividing so that current value highest in circuit, the rated power of the third operating mode of ECU3 matchings at this time so that diesel engine 2
Maximum power is maintained at the rated power of third operating mode.Foregoing circuit is simple in structure, and manufacturing cost is low, by electric current in circuit
Adjustment enable to the rated power of diesel engine 2 to be adjusted.
It should be pointed out that above-mentioned first resistor 100, the resistance value of second resistance 200 and 3rd resistor 300 and model can be with
It is identical, it can also be different, specific resistance value is determined according to specific 2 model of operating mode, that is, diesel engine.
Specifically, first stationary contact 101 is set at first gear, and second stationary contact 202 is set to
At second gear, the third stationary contact 301 is set at the third gear, and first gear is low or first gear, institute
It is mid ranger to state the second gear, and the third gear is top gear.Above-mentioned first gear is bottom gear, and gear correspondence uses gas less
Amount or the operating mode for using gas indirectly, the rated power after diesel engine 2 adjusts at this time is less than the rated speed that diesel engine 2 is demarcated
Half；Second gear is mid ranger, and the operating mode of tolerance during which corresponds to, the rated power after diesel engine 2 adjusts at this time is bavin
The half for the rated power that oil machine 2 is demarcated；Third gear is top gear, which corresponds to the operating mode of high tolerance, at this time diesel oil
Rated power after machine 2 adjusts is equal with the rated power that diesel engine 2 is demarcated.Can effectively it be met by specifically delimiting operating mode
The use demand of different operating modes.
It is to be appreciated that the practical gas consumption of operating mode corresponding to above-mentioned first gear is 1 specified gas consumption of air compressor machine
A quarter；The practical gas consumption of operating mode corresponding to second gear is the half of 1 specified gas consumption of air compressor machine；Third gear
The practical gas consumption of the corresponding operating mode is the specified gas consumption of air compressor machine 1.When practical gas consumption is in the first gear and second
When between gear, need the operation range selected for the second gear；When practical gas consumption be in the second gear and third gear it
Between when, need the operation range selected for third gear.
Specifically, the speed regulation device further includes having E-Gas 4, and the front end of the E-Gas 4 is sequentially connected with drive
The rear end of dynamic device, the E-Gas 4 is electrically connected the ECU3, and the driving device includes passing through pipeline with the gas tank 7
The servo cylinder 5 of connection is provided with proportioning valve 6 on the pipeline.Above-mentioned E-Gas 4 is controlled by servo cylinder 5, is watched
The air source of convinced cylinder 5 derives from gas tank 7, and is controlled by proportioning valve 6.For example, when the practical gas consumption of user is specified gas consumption
One third when, power adjustment switch 8 is threaded to mid ranger, when 1 practical gas consumption of air compressor machine by 0 increase moment (i.e. air bleeding valve 9
It is unexpected to increase), 7 pressure of gas tank declines, and 7 pressure of gas tank is less than proportioning valve 6 and sets pressure, the closing of proportioning valve 6 at this time, i.e. no gas
Stream becomes 0 by proportioning valve 6, at this time 5 pressure of servo cylinder, and cylinder stroke is minimum, and accelerator open degree is maximum.Since power adjustment is opened
It closes 8 and is threaded to mid ranger, engine speed is not up to rated speed n (corresponding rotating speed described in the rated power of calibration), but
Reach n1(n1＜ n), diesel engine 2 is in n1When gas production is more than gas consumption under rotating speed, 7 pressure of gas tank constantly rises, with gas tank 7
Pressure rises, and proportioning valve 6 is opened, and accelerator open degree reduces, and engine speed is gradually fallen after rise to stabilized (steady-state) speed.User in use can
Frequently stop the supple of gas or steam, with gas, by power adjustment switch 8, can to avoid diesel engine 2 between idling and highest empty wagons rotating speed frequent wave
It is dynamic, to reduce the oil consumption of diesel engine 2, and then improve the reliability of diesel engine 2.
Please refer to Fig.1 and Fig. 6, Fig. 1 be fuel-economizing governing system provided by the present invention structure diagram；Fig. 6 is the present invention
The flow chart of the fuel-economizing speed regulating method provided.

S2：Practical gas consumption is calculated according to actual condition parameter；The number so that practical gas consumption is calculated by calculating parameter
According to more accurate, to ensure that the adjustment of later stage rated power more has specific aim so that the rated power after adjustment can
Matching with actual condition is to higher.
S3：Adjust power adjustment switch 8 so that the rated power of diesel engine 2 matches with practical gas consumption；By adjusting
The rated power of diesel engine 2 so that diesel engine 2 can effectively reduce energy consumption while meeting actual condition, improve diesel engine 2
Service life and reliability.
S4：The threshold value for adjusting the rated power of diesel engine 2 in ECU3, matches best rated power；It is preset in ECU3 more
A rated power threshold value, multiple rated power threshold values match from different operating modes, by the way that actual condition is inputted ECU3, ECU3
Actual condition is matched with corresponding rated power threshold value, so that diesel engine 2 executes the rated power after matching, in turn
So that diesel engine 2 while meeting actual production, can effectively reduce oil consumption, the reliability of diesel engine 2 is improved.
S5：Export the rotating speed between idling and best rated power.
Further, in the step S1, institute's actual condition parameter includes actual borehole diameter d1With actual borehole depth
Spend h1；
In the step S2, the calculation formula of the practical gas consumption is：
Wherein Q is specified gas consumption, and f is coefficient value 2, and D is specified bore diameter, and h is specified drilling depth.

Power adjustment switch 8 is adjusted to corresponding operating mode gear according to practical gas consumption.
Specifically, the threshold value of the rated power of the diesel engine 2 includes low speed value, middling speed value and high speed value, the low speed
When value,When the middling speed value,When the high speed value, q=Q.
Above-mentioned fuel-economizing speed regulating method is according to the rated power of different Operating condition adjustment diesel engines 2, the rotation speed change of diesel engine 2
It is maintained at smaller range, effectively reduces the oil consumption of diesel engine 2 so that exhaust emissions meets environmental requirement, while 2 turns of diesel engine
The small service life that can ensure diesel engine 2 of variation range of speed, effectively improves the reliability of diesel engine 2.
