Abstract
The utility model discloses a crude oil engine pneumatic speed regulation control device, relates to a control device of crude oil engine pneumatic speed regulation or halt, and mainly solves the problems that when an engine is regulated in speed on severe environment conditions such as oil fields or coal mines, precision is not easy to control due to far distance when the speed is regulated manually, a circuit is complex when the speed is regulated electronically, and elements and wires can be damaged easily to cause shortcut at remote control time. According to the crude oil engine pneumatic speed regulation control device, an air outlet end of a gas storage tank is connected with an engine pneumatic actuator through a hand wheel regulating valve, a control end of the engine pneumatic actuator is connected with an engine accelerator operation rod, a compressor arranged on the engine is utilized to provided air sources, the location of an engine accelerator is controlled through adjustment of the magnitude of airflows so that the engine is regulated in speed. The crude oil engine pneumatic speed regulation control device is safe to use, simple in operation, safe, and reliable.
Description
Technical field
The utility model relates to a kind of diesel engine speed regulation device, relates to specifically the control gear of the pneumatic speed governing of diesel engine or parking.
Background technique
In the interior of motor vehicles member, internal-combustion engine control fuel is called as throttle for the device of amount.The mode of known control throttle has the backguy throttle, to link to each other with gas pedal (perhaps directly using manual backguy) by steel wire one end, the other end links to each other with closure, throttle control is by backguy (stone dead wire) or pull bar, one end connects gas pedal, the other end joint valve interlock plate and working.When needs accelerate, the driver step on the throttle pedal or the pulling acceleration cable, the motor raising speed when needs slow down, is unclamped foot treadle or is loosened acceleration cable, engine speed lowers.Another is electronic speed regulation, and its method is by replacing drag-line or pull bar with wire, at the exterior miniature motor of closure, driving throttle opening with motor.In the oil field, the dangerous place such as inflammable gas, gas explosion, short circuit appears in colliery, well head, down-hole easily, if adopt aforesaid way control throttle, exist manual governing wayward apart from backguy precision too far away, electronic speed-regulating circuit is complicated, components and parts, the fragile short circuit of wire when telecontrol.
Summary of the invention
The purpose of this utility model is: for above-mentioned deficiency, and propose a kind of safe and reliable, easy to use, the pneumatic speed governer of diesel engine simple to operate.
Technical solution of the present utility model is: the pneumatic speed governer of diesel engine is to pass through handwheel modulating valve sending and receiving motivation pneumatic actuator in the outlet side of gas holder, and the control end of motor final controlling element is connected with the engine oil-valve operation bar.
Also stop valve by urgency on the outlet side of the gas holder described in the technical solution of the present utility model and be connected with respectively pneumoelectric throw over switch and air inlet shut-off valve.
Handwheel modulating valve described in the technical solution of the present utility model is parallel with the remote adjustment valve by switching valve sending and receiving motivation pneumatic actuator at the handwheel modulating valve.
Gas holder described in the technical solution of the present utility model carries air compressor by Filter dryer and motor and is connected.
Urgency described in the technical solution of the present utility model is stopped being parallel with on the valve long-range urgency and is stopped valve.
The compressor that the utility model adopts motor to carry provides source of the gas, the speed governing or the shutdown control that realize motor by regulating the air-flow size.After engine start, air flows to exsiccator after the air compressor compression, air after the filtration is by control valve sending and receiving motivation pneumatic actuator, regulate the purpose that throttle position reaches speed governing or parking by the length that the pneumatic final controlling element cylinder of motor stretches out, the utility model also is provided with Remote control valve, can guarantee remote-controlled operation under the condition of the rugged environment such as oil field, colliery; The utility model uses safety, and is simple to operate, safe and reliable.
Description of drawings
Fig. 1 is fundamental diagram of the present utility model.
Embodiment
As shown in Figure 1, the air compressor that motor carries connects gas holder 7 by Filter dryer 8, the outlet side of gas holder 7 is by handwheel modulating valve 6 sending and receiving motivation pneumatic actuators 10, the control end of the pneumatic final controlling element 10 of motor is connected with engine oil-valve operation bar 9, and the pneumatic final controlling element 10 of motor is cylinders; Behind engine start, air compressor is started working, make the pressurized air that slowly stores certain pressure in the gas holder 7, rotate handwheel modulating valve 6, pressurized air enters the pneumatic final controlling element 10 of motor, and the pneumatic final controlling element 10 of motor is started working, and the length of being stretched out by pneumatic final controlling element 10 cylinders of motor drives 9 work of engine oil-valve operation bar, thereby regulate the position of engine throttle, until motor reaches rated speed; When motor need to slow down, rotate handwheel modulating valve 6, the air that control is sent in the pneumatic final controlling element 10 of motor gets final product; The outlet side of gas holder 7 by anxious stop valve 3 respectively with motor on pneumoelectric throw over switch 1 are connected with the air inlet shut-off valve and are connected, when needs stop in emergency, press the anxious valve 3 that stops, one road air-flow is converted to the oil supply circuit that electrical signal cuts off motor by the pneumoelectric throw over switch 1 on the motor, and another road air-flow is directly blocked the air inlet pipeline of motor to air inlet shut-off valve 2 by tee union; Because may being operated in oil field, colliery etc., motor is difficult for the closely place of operation, pipeline between handwheel modulating valve 6 and the pneumatic final controlling element 10 of motor is connected with a switching valve 11, be parallel with remote adjustment valve 5 on the handwheel modulating valve 6, select handwheel modulating valve 6 or remote adjustment valve 5 to come control engine pneumatic actuator 10 by switching valve 11, be parallel with long-range urgency and stop valve 4 at the anxious valve 3 that stops, stop valve 3 or long-range urgency is stopped valve 4 control pneumoelectric throw over switch 1 and air inlet shut-off valves 2 by anxious.
