Abstract
The utility model discloses a pneumatic starting system of an explosion-proof diesel engine, which is characterized in that an air storage barrel is connected to a pneumatic starter through an air pipe, and the middle position of the air pipe is also provided with a relay valve for controlling the air pipe to be connected and disconnected. In addition, the pneumatic starting system is also provided with two control air paths, wherein one control air path is connected with the pneumatic starter from the air storage barrel through an oil control air cut valve and a starting switch, and the other control air path is connected to the relay valve from the pneumatic starter. By operating the starting switch, the pneumatic starter works so as to further start the diesel engine.
Description
Technical field
The utility model relates to a kind of anti-explosion diesel engine gas starting system, belongs to the anti-explosion diesel engine field.
Background technique
At present, contain the material transportation in explosive gas atmosphere under coal mine, the starting arrangement of Traditional Transportation vehicle also is not suitable for.Be mainly that anti-explosion electric starts the reasons such as bad due to thermal diffusivity, that brush very easily weares and teares because it uses the anti-explosion electric starting mostly, cause the anti-explosion electric starting shorter working life.
The model utility content
Model utility purpose: the utility model proposes a kind of anti-explosion diesel engine gas starting system, can greatly extend the working life of starter motor in anti-explosion diesel engine.
Technological scheme: the technical solution adopted in the utility model is a kind of anti-explosion diesel engine gas starting system, and this system comprises a main gas circuit and two control gas circuits.Main gas circuit comprises gas receiver, gas starter motor and the relay valve between the gentle starter motor of gas receiver of storing compressed air.Gas receiver is connected to the gas starter motor by a tracheae, and the tracheae neutral position is provided with relay valve, controls the break-make of tracheae.Controlling gas circuit has two, and one is from gas receiver, and process oil control ACV Air Cut Valve and switch starter are to the control tracheae suction port of gas starter motor.Another controls the control gas port of gas circuit from the control air pipe outlet of gas starter motor to relay valve.
During starting, open switch starter, control gas and enter the control gas port of relay valve through the gas starter motor, relay valve makes the tracheae conducting that connects between gas receiver and gas starter motor under the effect of controlling gas, the work of gas starter motor, and then starting diesel engine.
As a further improvement on the present invention, described oil control ACV Air Cut Valve is provided with a control interface, and this control interface is connected to the lubricating oil path of diesel engine, makes oil control ACV Air Cut Valve controlled by lubricating oil pressure.When diesel engine starts to work, pressure from the diesel lubrication oil circuit, drive oil control ACV Air Cut Valve cutting-off controlling gas circuit, even switch starter has been opened in misoperation this moment, can not make the work of gas starter motor yet, that causes starter motor and diesel engine flywheel gear ring beats the tooth phenomenon, has avoided the damage of starter motor.
Beneficial effect: the utility model can extend the working life of starter motor in anti-explosion diesel engine in use greatly, and can prevent the misoperation to the gas starter motor.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand these embodiments only is used for explanation the utility model and is not used in restriction scope of the present utility model, after having read the utility model, those skilled in the art all fall within the application's claims limited range to the modification of the various equivalent form of values of the present invention.
As shown in Figure 1, the utility model comprises gas receiver 1, relay valve 2, gas starter motor 3, switch starter 4 and oil control ACV Air Cut Valve 5.Gas receiver 1 is connected to gas starter motor 3 by tracheae, is provided with relay valve 2 in the centre of this tracheae, controls the break-make of tracheae.Also have two to control gas circuit, one is gas receiver 1, through oil control ACV Air Cut Valve 5 and switch starter 4, is connected to the control tracheae suction port of gas starter motor 3.Another is controlled gas circuit and is connected to the control gas port of relay valve 2 from the control air pipe outlet of gas starter motor 3.Described oil control ACV Air Cut Valve 5 also is provided with a control interface 6, and this control interface 6 is connected to the lubricating oil path of diesel engine.
During starting, open switch starter 4, pressurized air enters the control gas port of relay valve 2 through gas starter motor 3, and relay valve 2 makes the tracheae conducting that connects between gas receiver 1 and gas starter motor 3 under the effect of controlling gas, 3 work of gas starter motor, and then starting diesel engine.When diesel engine starts to work, pressure from the diesel lubrication oil circuit, drive oil control ACV Air Cut Valve 5 cutting-off controlling gas circuits by control interface 6, even switch starter 4 has been opened in misoperation this moment, can not make the work of gas starter motor yet, that causes starter motor and diesel engine flywheel gear ring beats the tooth phenomenon, has avoided the damage of starter motor.
