Abstract
The invention relates to a speed regulating system of a diesel engine, particularly to a pneumatic speed regulating system of an electronic control diesel engine. The pneumatic speed regulating system of the electronic control diesel engine mainly aims at solving the problems that the speed regulation is performed on the diesel engine through known electronic control fuel injection, the functions of the diesel engine are achieved through an electronic module, and an electronic control module of the diesel engine cannot be directly controlled by an ordinary pneumatic speed regulating system to achieve the speed regulation of the diesel engine. The pneumatic speed regulating system of the electronic control diesel engine comprises an air storage tank, a handle pressure regulating valve and a pneumatic actuator. The pneumatic speed regulating system of the electronic control diesel engine is characterized in that a handle of an electronic handle throttle is connected with a control lever of the pneumatic actuator through a connecting rod and the electronic handle throttle is electrically connected with an electronic control module through a wiring harness. According to the pneumatic speed regulating system of the electronic control diesel engine, the electronic handle throttle is added between the existing mechanical diesel engine pneumatic speed regulating system and the electronic control module of the electronic control diesel engine and accordingly the pneumatic speed regulation of the electronic control diesel engine can be achieved, the structure is simple, and the implementation is easy.
Description
Technical field
The present invention relates to a kind of speed control system of diesel engine, thereby specifically relate to a kind of device of the electronic control module adjusting electronic controlled diesel rotating speed that uses atmospheric control to handle diesel engine.
Background technique
At petroleum chemical industry, many employing diesel engines are as the petroleum machinery of active force, owing to being all in most cases operation under inflammable and explosive operating mode, therefore also all can there be some simple requirement of explosion proof for diesel engine, as the speed control system that requires diesel engine adopts pneumatic speed governing, common mechanical type diesel engine only need be connected pneumatic actuator with the mechanical type throttle lever of diesel engine, by the size of adjustments of gas pressure, just can realize the pneumatic speed governing of diesel engine; And for automatically controlled, namely adopt control fuel injection to carry out speed governing to diesel engine, all functions of diesel engine all realize by electronic control module ECM, and ECM controls by circuit, the electronic control module that therefore common pneumatic speed control system just cannot be manipulated diesel engine directly by gas circuit is to realize the speed governing of diesel engine.
Summary of the invention
The object of the invention is for above-mentioned deficiency, and a kind of pneumatic speed control system of utilizing the electronic control module of pneumatic speed control system direct manipulation diesel engine to realize electronic controlled diesel proposing.
Technical solution of the present invention is: the pneumatic speed control system of electronic controlled diesel comprises gas holder, handle pressure regulator valve, pneumatic actuator, it is characterized in that: the handle of electric handle throttle is connected with the operating handle of pneumatic actuator by connecting rod, and electric handle throttle is electrically connected with electronic control module by wire harness.
The present invention is only need be in existing mechanical type diesel engine air speed control system, be between gas holder, handle pressure regulator valve and pneumatic actuator and electronic controlled diesel electronic control module, to increase an electric handle throttle, just can realize the pneumatic speed governing of electronic controlled diesel, therefore simple in structure, be easy to realize.
Accompanying drawing explanation
Fig. 1 is the structural representation of electronic controlled diesel low speed state of the present invention.
Fig. 2 is the structural representation of electronic controlled diesel raising speed state of the present invention.
Embodiment
As shown in Figure 1 and Figure 2, the present invention includes gas holder 1, handle pressure regulator valve 3, tracheae 4, pneumatic actuator 5, connecting rod 7, electric handle throttle 9, wire harness 10 and electronic controlled diesel electronic control module 11.Source of the gas outlet and the suction port of handle pressure regulator valve 3 of gas holder 1 link together by tracheae, the air outlet of handle pressure regulator valve 3 is connected with the suction port of pneumatic actuator 5 by tracheae 4 again, one end of connecting rod 7 is connected with the operating handle 6 of pneumatic actuator 5, the handle 8 of the other end and electric handle throttle 9 links together, and electric handle throttle 9 is final to be connected with electronic control module 11 electricity by wire harness 10.Electric handle throttle 9 adopts commercially available existing procucts.Working principle: as shown in Figure 1, in the time that the handle of handle pressure regulator valve 32 is slowly pulled to counter clockwise direction, gas flow by handle pressure regulator valve 3 reduces gradually, thereby cause the gas pressure that enters pneumatic actuator 5 also to reduce gradually, the operating handle 6 of pneumatic actuator 5 same rotating to counter clockwise direction under the effect of the Returnning spring of pneumatic actuator 5 inside like this, operating handle 6 pulls connecting rod 7 to move to the left in Fig. 1, connecting rod 7 drives again the handle 8 of electric handle throttle 9 counterclockwise to rotate, along with the rotation of handle 8, the just analog signals reducing gradually of synchronous output of controller that electric handle throttle 9 is built-in, this signal passes to electronic control module 11 by wire harness 10, electronic control module 11 just reduces the rotating speed of electronic controlled diesel gradually, as shown in Figure 2, in the time that the handle of handle pressure regulator valve 32 is slowly pulled to clockwise direction, gas flow by handle pressure regulator valve 3 increases gradually, thereby cause the gas pressure that enters pneumatic actuator 5 also to increase gradually, the operating handle 6 of pneumatic actuator 5 same rotating to clockwise direction under gas pressure like this, operating handle 6 promotes connecting rod 7 to the right-hand motion in Fig. 2, connecting rod 7 drives again handle 8 clockwise directions of electric handle throttle 9 to rotate, along with the rotation of handle 8, just analog signals increasing gradually of synchronous output of controller that electric handle throttle 9 is built-in, this signal passes to electronic control module 11 by wire harness 10, electronic control module 11 is with regard to the rotating speed of the electronic controlled diesel that raises gradually.
