Gases at high pressure in plant equipment directly to airborne release when the noise pollution that produces and energy dissipation.
Description of the drawings
With reference to the accompanying drawings and examples the invention will be further described.
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the pneumatic starting device control principle drawing of the present invention.
Specific embodiment
As shown in figure 1, be provided with ears Flywheel disc 8 on the flywheel of Diesel engine 15, ears Flywheel disc 8 and gear pair one
7th, the internal messing of gear pair 2 14 is together.The gear pair 1 of electric starter system is arranged on power transmission shaft 1, and power transmission shaft 1 leads to
Cross clutch 1 to be connected with the main shaft of electric rotating machine 5.The main shaft of linear electric motors 2 is connected with shift fork 1, shift fork 1 and clutch
One 4 connections.Therefore when the main shaft of linear electric motors 2 is flexible, horizontally slipping for clutch 1 can be realized by shift fork 1, finally
Realize clutch 1, power transmission shaft 1, the connection of the main shaft of electric rotating machine 5 and separate.
The gear pair 2 14 of pneumatic starting device be arranged on power transmission shaft 2 13 on, power transmission shaft 2 13 by clutch 2 11 with
The main shaft connection of air motor 12.The piston rod of cylinder 9 is connected with shift fork 2 10, and shift fork 2 10 is connected with clutch 2 11.Cause
This can realize horizontally slipping for clutch 2 11 when the piston rod of cylinder 9 is flexible by shift fork 2 10, finally realize clutch
2 11, power transmission shaft 2 13, the main shaft of air motor 12 connect and separate.
The accumulator 1 of the present invention is connected respectively with electric rotating machine 5, linear electric motors 2.Two sets are designed on Diesel engine 15
Launcher, a set of using traditional electric starter system, other set then adopts pneumatic starting device.Two sets of launcher peaces
It is mounted on ears Flywheel disc 8.When electrically activating unsuccessfully, pneumatic mode assistant starting Diesel engine 15 can be rapidly utilized.
When accumulator 1 is by wire and switch drive linear electric motors 2, the main shaft of linear electric motors 2 is promoted by shift fork 1
