Abstract
The utility model provides a diesel engine multi-start-way layout structure and relates to a diesel engine, in particular to the diesel engine multi-start-way layout structure. The diesel engine multi-start-way layout structure mainly solves the problems that an existing diesel engine is time-consuming and labor-consuming to start by adopting labor force to rotate an inertia wheel, normal start can not be guaranteed due to start through a storage battery when voltage is abnormal, and timeliness and safety of start of the diesel engine are difficult to guarantee on the condition of emergencies. According to the diesel engine multi-start-way layout structure, a double-ear flywheel case is fixedly arranged on the rear end face of the engine, and a pneumatic motor installation hole position and a hydraulic motor installation hole position are arranged on the double-ear flywheel case. A pneumatic motor and a hydraulic motor of two different start ways are adopted as start motors of the diesel engine, when the pneumatic motor is not started successfully, the hydraulic motor can be adopted for starting, and therefore the diesel engine can be started normally under whatever environment.
Description
Technical field
The utility model relates to a kind of diesel engine, is specifically related to many Starting mode of diesel engine layout structure.
Technical background
As everyone knows, the startup of diesel engine needs the mist of oil mixed gas in the spark ignitor cylinder unlike petrol engine, diesel engine needs auxiliary actuator to come the flywheel driven High Rotation Speed before startup, comes the mixed gas of " lighting " each cylinder sleeve to come work thereby drive piston compression mixed gas to burning-point.The tool historical summary shows, is all to adopt manual mode to start diesel engine by manpower rotator inertia wheel in the past, and at present a lot of agricultural use single cylinder diesels also keep this Starting mode.This Starting mode takes time and effort, and is difficult to normally with engine start work.Domestic patent application 200920289454.X proposes a kind of double startup layout structure, Yi Bian adopt modern electric starting motor to start; Adopt the topology layout of mechanical type spring type mechanical accumulator on one side.The advantage of this structure is to adopt when normally starting electric starting motor to start, and starts unsuccessfully to adopt the spring type mechanical accumulator mechanical type to start.This structure has been optimized the start-up safety energy greatly, but starting, electric starting motor need storage battery to provide the 24V voltage just can normal rotation, yet storage battery is owing to there being self-discharge characteristics, and need not or not charging for a long time is difficult to ensure 24V voltage, also just can not normally start successfully.If adopt the mechanical type spring type mechanical accumulator to start, because spring type mechanical accumulator once can only use once, secondary uses needs artificial " holding power ", needs in the meantime the 2-3 minutes, is difficult to guarantee ageing.Along with industrial expansion, this Starting mode can not satisfy the demand of modern industrialization, especially be applied to the fields such as the in time water supply of steel mill's blast furnace is emergent, oil extraction in oil field is safe and reliable, these applications require standard all very high to the startup of motor, and require to start safe and reliable.Particularly adopt diesel engine to supply water to steel-making blast furnace as power source in steel mill emergent, need to start in the water supply network decompression diesel engine in 15 seconds and drive water pump and supply water to blast furnace; As power source work, can not directly adopt electricity to start contour standard-required for avoiding producing electrical spark in the oil field, the ageing and safety reliability that all diesel engine is started has proposed challenge.
Summary of the invention
The purpose of this utility model is not enough for above-mentioned diesel engine starting performance, and provides a kind of timeliness that can guarantee, time saving and energy saving, efficient, safe and reliable many Starting mode of diesel engine layout structure.
Technical solution of the present utility model is: many Starting mode of diesel engine layout structure is: be fixed with an ears flywheel casing on the ear end face of motor, be provided with pneumatic motor mounting hole site and oil hydraulic motor mounting hole site on the ears flywheel casing.
Position, pneumatic motor hole described in technical solution of the present utility model is located at the upper right of ears flywheel casing, and the oil hydraulic motor mounting hole site is located at the front-left of ears flywheel casing.
Be bolted pneumatic motor on pneumatic motor mounting hole site described in technical solution of the present utility model, be bolted oil hydraulic motor on the oil hydraulic motor mounting hole site.
The utility model adopts a kind of ears flywheel casing to be fixed on after motor on mounting plane, is designed with the pneumatic motor mounting hole site on this ears flywheel casing, the oil hydraulic motor mounting hole site.The conventional startup of diesel engine adopts pneumatic motor to start, if pneumatic motor breaks down or to start system air pressure not enough and start unsuccessfully, transfer oil hydraulic motor to and start, thereby diesel engine has effectively been avoided can't starting because of what electric notor startup weakness caused the industrial accident that brings.The utility model can guarantee fully that owing to having adopted two kinds of different Starting mode diesel engine can normally start in any environment, the utility model reasonable in design, compact structure, be simple and easy to the dress, widely applicable.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the left view of Fig. 1.
Embodiment
As shown in Figure 1, 2, ears flywheel casing 1 adopts bolt to be fixed on the motor ear end face, on ears flywheel casing 1, layout has pneumatic motor mounting hole site 3, oil hydraulic motor mounting hole site 4, motor ear end face from Fig. 2, pneumatic motor mounting hole site 3 is positioned at the upper right of ears flywheel casing 1, and oil hydraulic motor mounting hole site 4 is positioned at the ears flywheel casing 1 positive left side.Pneumatic motor 2 adopts bolt to be fixed on pneumatic motor mounting hole site 3, and oil hydraulic motor 5 adopts bolt to be fixed on oil hydraulic motor mounting hole site 4.Adopt pneumatic motor 2 to start when motor need to start, cause diesel engine to start if pneumatic motor 2 breaks down or air-channel system air pressure not enough, just start diesel engine by primer fluid pressure motor 5 this moment.Can guarantee effectively that by the utility model diesel engine under any circumstance normally starts.
