Abstract
The utility model discloses a diesel oil/natural gas double-fuel supply system, which includes a diesel oil fuel supply subsystem, a natural gas fuel supply subsystem and a PLC control system, wherein a gas mixing system connected with natural gas is additionally arranged on the existing diesel oil engine block. The diesel oil/natural gas double-fuel supply system solves the problem of diesel oil shortage and reduces the problems of environmental pollution and the like caused by diesel oil exhaust.
Description
Technical field
The utility model relates to motor supply system technical field, is specifically related to a kind of diesel/natural gas dual-fuel supply system.
Background technique
At present, be that the big-and-middle-sized working equipment such as engineering machinery (bulldozer, excavator), mining machinery (rig, ore crusher, draw large junk), motor vehicle, power vessels, generator set of power is widely used in each field of national economy with the DENG.Therefore, aggravated oil-fired nervous disappearance, its diesel oil exists all when work that exhaust smoke is big, the more problem of fraction of particle in the smog, causes bigger pollution to environment easily with this.
In order to solve above-mentioned deficiency of the prior art, the utility model provides a kind of new solution.
The model utility content
The utility model technical problem to be solved is: a kind of diesel/natural gas dual-fuel supply system is provided, the mixed gas system that it has increased on existing DENG group that one group of rock gas joins.This diesel/natural gas dual-fuel supply system when solving the nervous disappearance of diesel oil, also reduced because of diesel exhaust gas to problems such as environment pollute.
For reaching the foregoing invention purpose; The technological scheme that the utility model adopted is: a kind of diesel/natural gas dual-fuel supply system is provided; Comprise that diesel fuel is supplied with subtense angle, gas fuel is supplied with subtense angle and PLC control system; It is characterized in that: said diesel fuel is supplied with subtense angle and is comprised diesel fuel tank, is disposed with diesel fuel filter, diesel oil stop valve on the said diesel fuel tank oil supply pipeline, and diesel fuel tank pipeline output terminal links to each other with the input end of high-pressure service pump through oil supply pipeline; Said high pressure delivery side of pump links to each other with the nozzle of motor.
Said rock gas is supplied with subtense angle and is comprised the rock gas storage tube, and said rock gas storage tube inside is provided with the gas fuel filter cleaner; Be disposed with stop valve, one-way valve on the outlet port steam line of said gas fuel filter cleaner, and link to each other with the import of vaporizer; The outlet of said vaporizer links to each other with air Mixture through automatic block valve, manual modulation valve;
The input end of said PLC control system is connected with speed probe, fuel level sensor, oil temperature sensor, natural gas flowmeter, pressure transducer, natural gas temperature sensor respectively.
In sum, the diesel/natural gas dual-fuel supply system that the utility model provided has the following advantages than existing technology:
1, do not change the structure and the mode of operation of former DENG, the compression that does not change former motor is firing mode when;
2, motor both can burn pure diesel oil, also can burn the fuel combination of rock gas and diesel oil;
3, the fuel combination of diesel/natural gas and pure diesel fuel, are transformed into and burn pure diesel oil when not having rock gas up to conversion;
4, DENG transform rock gas/diesel dual-fuel motor as, because the igniting of many burning things which may cause a fire disaster, burning is complete, concentration of energy, and power remains unchanged, and power performance also improves (10%) to some extent during the heavy load situation.
