Abstract
The utility model discloses an air pressure and fan dual-control regulating system of a spreading machine heating system, and belongs to the field of spreading machine equipment. The air pressure and fan dual-control regulating system comprises a fuel gas tank, an air blower, an ironing plate, a fuel gas pressure control valve, a potentiometer and a controller, wherein the air blower is arranged on the ironing plate, and the fuel gas pressure control valve is arranged on a pipeline arranged outside the fuel gas tank; and the controller is respectively connected with the potentiometer and the air blower. The air pressure and fan dual-control regulating system adopts a mode that the adjustable fuel gas pressure control valve and an stepless speed regulating system of the air blower are matched, so that the flame is guaranteed to jet an ironing plate wear-resisting plate, the fuel gas is guaranteed to be subjected to sufficient combustion, and the air pressure and fan dual-control regulating system achieves the effects of easiness for ignition and gas conservation.
Description
Technical field
The utility model relates to a kind of paver, and specifically a kind of air pressure of paver heating system and fan dual control regulating system belong to the paver apparatus field.
Background technology
Paver is a kind of construction equipment that is mainly used in basic unit and the various material paving operations of surface layer on the speedway.
Existing paver gas heating system is the air pressure by regulating gas substantially, comes air inflow, the gas mixture ratio when regulating the ignition and combustion of heating system of regulating gas; The intake of blast fan is decided by the caliber size of the air inlet port of blast fan.
The problem that exists in reality is used has:
1. wind speed of blast blower is excessive in igniting, even the pressure of combustion gas is jumped to suitable ratio value, the gas that the flare of just having lighted still can be blown out by too fast blast fan is blown out.
2. after reducing the adjusting of blast fan air inflow, combustion gas can not get sufficient burning meeting combustion gas is caused waste.
Summary of the invention
For the problem that above-mentioned prior art exists, the utility model provides a kind of air pressure and fan dual control regulating system of paver heating system, and combustion gas both can be lighted easily during igniting, can fully burn again.
To achieve these goals, the technical solution adopted in the utility model is: a kind of air pressure of paver heating system and fan dual control regulating system, comprise fuel cartridge, blast fan and screed, blast fan is arranged on the screed, also comprise gaseous-pressure control valve, potentiometer and controller, the gaseous-pressure control valve is arranged on the outer pipeline of fuel cartridge, and controller is connected with blast fan with potentiometer respectively.
Further, controller is provided with PWM frequency modulation delivery outlet.
The beneficial effects of the utility model are: the mode that native system adopts the continuous speed regulation system of adjustable gaseous-pressure control valve and blast fan to match; in igniting, allow the blast fan low cruise; so that the mixing ratio of combustion gas and air is as long as just can light easily in flammable range; light the rear rotating speed of blast fan and the pressure of combustion gas of strengthening simultaneously; can guarantee that in this process flame can not extinguish; after reaching at a high speed, can guarantee that flame is ejected into the screed wearing plate; can guarantee that again combustion gas is fully burned, and has reached easily and has lighted; save the effect of combustion gas.
Description of drawings
Fig. 1 is the utility model principle schematic.
The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
As shown in Figure 1, the air pressure of the utility model paver heating system and fan dual control regulating system, comprise fuel cartridge, blast fan and screed, blast fan is arranged on the screed, it is characterized in that, also comprise gaseous-pressure control valve, potentiometer and controller, the gaseous-pressure control valve is arranged on the outer pipeline of fuel cartridge, and controller is connected with blast fan with potentiometer respectively; Described controller is provided with PWM frequency modulation delivery outlet.
During work, combustion gas in the fuel cartridge is controlled by the gaseous-pressure control valve, the continuous speed regulation system of blast fan carries out work, export to the controller voltage variety by potentiometer, by controller PWM frequency modulation delivery outlet output frequency modulation electric current, the variation of the dutycycle of PWM output current directly determines the rotating speed of blast fan.In igniting, allow the blast fan low cruise; so that the mixing ratio of combustion gas and air is as long as just can light easily in flammable range; light the rear rotating speed of blast fan and the pressure of combustion gas of strengthening simultaneously; can guarantee that in this process flame can not extinguish; after reaching at a high speed, can guarantee that flame is ejected into the screed wearing plate; can guarantee that again combustion gas is fully burned, and has reached the effect of easily lighting, saving combustion gas.
Claims (2)
