The utility model which has the advantages of novel design, simple structure, adopting the natural gas as the energy is safe and environmental protective. Meanwhile, the utility model can effectively control the amount of the gas inlet to ensure the relative constant rotational speed of the engine and the normal and lasting generation of the generating set.
Description
Technical field
The utility model relates to a kind of generator set, especially a kind of natural gas liquid gasification generator set.
Background technique
Normally used generator set is generally diesel generating set, along with improving constantly of fuel price, adopt the cost of fuel oil generating also to improve thereupon, simultaneously, use diesel generator, to a certain degree can produce environmental pollution, and rock gas is still possessed sufficient deposit, exploitation is the direction that the natural gas liquid gasification generator set of the energy becomes the development of new generator set with the rock gas.Employing natural gas liquid gasification has also appearred at present as the energy generator group, but this class generator set or gas discharge control structure more complicated, air inflow to rock gas can not effectively be controlled, and guaranteeing to continue constant air inlet, thereby influences the normal operation of complete machine.
Summary of the invention
Can cause environmental pollution, deficiency that user cost is high in order to overcome common diesel generating set, the utility model provides a kind of natural gas liquid gasification generator set.
The technical problems to be solved in the utility model is: a kind of natural gas liquid gasification generator set, have motor, generator, engine driven generators, the utility model adopts the energy of rock gas as motor, described motor is circumscribed with main suction tude, main suction tude is connected with an end of mixer, and the other end of mixer is connected with air intake duct with the rock gas suction tude; Described mixer comprises the closure that is used to control gas discharge, is used to control the stepper motor and the control circuit of throttle opening; Starting gear ring outer rim at motor is provided with the tachogenerator that is used for the detection of engine rotating speed and feedback information is arrived control circuit.By being used in combination that tachogenerator, control circuit, stepper motor and closure reach, the flow of rock gas and the rotating speed of motor are linked together.When engine operation, the variation of load can cause the variation of engine speed, when motor has very fast rotating speed, tachogenerator feeds back to the tach signal that records the control circuit that has microprocessor chip, control stepper motor by control circuit, by stepper motor the pipeline aperture of closure is regulated again: when engine speed is on the low side, throttle forward, increase gas discharge, thereby improve rotating speed; Otherwise, when engine speed is higher, reduce closure, reduce gas discharge, thereby reduce rotating speed, the invariablenes turning speed of motor is controlled on some points, the rotating speed of controlling motor usually is 1500,1800,3000 or 3600 rev/mins.
The closure of above-mentioned composition mixer, stepper motor and control circuit can integrate structure, realize electromechanical integration, the convenient use, in addition, closure can be arranged on separately on the rock gas suction tude pipeline, and stepper motor and control circuit be installed in other position of unit, disperse the flexible Application spatial arrangement is installed.
For engine speed is accurately detected, need tachogenerator to get close to the starting gear ring of motor as far as possible, further: the gap of described tachogenerator and starting gear ring outer rim is 1～3mm.
Because rock gas enters aperture and the gas pressure intensity two aspects decision of the amount of motor by closure, in order to guarantee that the combustion gas that enters motor has constant air inlet pressure, further: described suction tude is provided with the voltage-regulation voltage-stabilization valve, by setting suitable regulated value, when there is to a certain extent variation in the gas pressure intensity that comes from pipeline or liquid gas, by behind the voltage-regulation voltage-stabilization valve, the gas of supply engine closure still can reach the air inlet pressure that motor requires at gas.
In order when generator set quits work, to cut off the supply of source of the gas, increase Security, more further: described suction tude is provided with solenoid valve.
Bring foreign material when preventing that ambient air from entering pipeline into, influence the proper functioning of the unimpeded and airflow passes facility of pipeline, further: the setting of described air intake duct suction port is free filter, has guaranteed the degree of purity when air enters air intake duct, has guaranteed the air inlet quality.
The beneficial effects of the utility model are, and are novel in design, simple in structure, adopt rock gas as the energy, and environmental protection safe in utilization simultaneously, can have been implemented effective control to air inflow, makes motor keep relative constant rotational speed, and what guarantee generator set normally continues generating.
