Description
Technical field
The utility model relates to a kind of diesel engine of locomotive starting system, especially a kind of diesel engine of locomotive nitrogen starting system.
Background technique
The general wind starting of adopting total reservoir of explosion-proof diesel engine of diesel locomotive gas start mode before the diesel engine of locomotive unstart, need be filled wind to total reservoir, and blast just can start after reaching certain pressure.Correspondingly need the user side to be equipped with air pump station and additional other expense, train starting will postpone, and causes unnecessary trouble to the user, reduces income.
The model utility content
The technical problems to be solved in the utility model is: also need to be equipped with problems such as air pump station and train starting delay in order to overcome existing diesel engine of locomotive starting, the utility model provides a kind of diesel engine of locomotive nitrogen starting system, do not need the user to be equipped with the air pump station in addition, reduced unnecessary trouble.
The technological scheme that its technical problem that solves the utility model adopts is: a kind of diesel engine of locomotive nitrogen starting system, have total reservoir and pneumatic motor, total external air system of reservoir, total reservoir is communicated with successively by pipeline and is provided with reduction valve and nitrogen bottle, the outlet port of nitrogen bottle is provided with outlet valve, outlet valve is connected with reduction valve, also be provided with ball valve between total reservoir and the pneumatic motor, air feeding apparatus and main pipe, air feeding apparatus one end is connected by ball valve with pipeline, the air feeding apparatus the other end links to each other with pneumatic motor by main pipe, the air feeding apparatus upper end is provided with import, inside is provided with main valve that communicates with main pipe and the branch valve of being controlled by starting button, divides valve to communicate with the import of air feeding apparatus by start button.
The main valve place of air feeding apparatus also is communicated with and is provided with lubricating fitting, and lubricating fitting is connected with main pipe, is convenient to lubricated pneumatic motor.
The beneficial effects of the utility model are: do not need to be equipped with in addition the air pump station, diesel engine of locomotive can start at any time, and is easy and simple to handle, saves time the reduction expense.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1. total reservoir, 11. pipelines, 2. reduction valve, 3. nitrogen bottle, 31. outlet valves, 4. ball valve, 5. air feeding apparatus, 51. fens valves, 6. main pipe, 7. starting button, 8. pneumatic motor.
Embodiment
As shown in Figure 1, a kind of diesel engine of locomotive nitrogen starting system, have total reservoir 1 and pneumatic motor 8, total reservoir 1 external air system, total reservoir 1 is communicated with successively by pipeline 11 and is provided with reduction valve 2 and nitrogen bottle 3, the outlet port of nitrogen bottle 3 is provided with outlet valve 31, outlet valve 31 is connected with reduction valve 2, also be provided with ball valve 4 between total reservoir 1 and the pneumatic motor 8, air feeding apparatus 5 and main pipe 6, air feeding apparatus 5 one ends are connected by ball valve 4 with pipeline 11, air feeding apparatus 5 the other ends link to each other with pneumatic motor 8 by main pipe 6, air feeding apparatus 5 upper ends are provided with import, inside is provided with main valve that communicates with main pipe 6 and the branch valve of being controlled by starting button 7 51, divides valve 51 to communicate by the import of starting button 7 with air feeding apparatus 5.
The main valve place of air feeding apparatus 5 also is communicated with and is provided with lubricating fitting 9, and lubricating fitting 9 is connected with main pipe 6, is convenient to the pneumatic motor 8 of lubricated diesel engine.
Diesel engine of locomotive nitrogen starting system working principle is: open nitrogen bottle 3 outlet valves 31, reduction valve 2 outlet pressures are transferred to the user need pressure, when treating that total reservoir 1 blast reaches the user and needs pressure, open ball valve 4, press starting button 7, this moment, nitrogen entered air feeding apparatus 5 upper inlet by minute valve 51.It promotes the main valve in the air feeding apparatus 5 and connects main gas circuit, and nitrogen will feed pneumatic motor 8 in a large number, and pneumatic motor 8 rotates, and drives the diesel engine flywheel and rotates, and diesel engine will be got angry and be started; This moment, ingress, air feeding apparatus 5 upper end did not have the nitrogen feeding, and air feeding apparatus is closed main gas circuit immediately, and pneumatic motor promptly stops operating, and the starting process of diesel engine finishes also to close immediately nitrogen bottle 3 outlet valves 31 and ball valve 4.When the blast in the locomotive operation in total reservoir 1 reached the pressure of regulation, the wind starting diesel engine of available total reservoir 1 at this moment, only need be opened ball valve 4, presses starting button 7 and can start diesel engine.
