Pneumatic Starter for NTA855 KTA19 Diesel Engine
AST600 Air Starter is a device for starting diesel engine, use the
compressed air as power source. It has the merits of fire
protection, explosion protection, small volume, large power,
overload protection and safety and reliability in serious working
condition. Especially, pre-engagement starter method which the
output gear first extrude then rotate is realized to avoid to
damage the gear circle of flying wheel of diesel engine. This
product is our patented product, Used for NTA855, KTA19, 8135,
12V135, 8150, 6160, 4170, 6170, 8170, 4190, 6190, and 8190 diesel
engine.

2.Working Principle
AST600 Air Starter is comprise of power part and output part. The
power part is vane pneumatic motor. When starting the diesel
engine, the compressed air enter from pre-engagement air inlet hole
of output part and push the output part and push the output gear to
extrude forward, adjust automatically to ensure the correct
engaging position. When the output gear reaches specified stroke,
the compressed air is connected with air relay through
pre-engagement air outlet hale. At this time, open main air
circuit, the compressed air enter vane pneumatic motor part, and
the motor starts to rotate which drive the diesel engine. After
start-up o of diesel engine the said motor will overstep by
overstep clutch. If the air source is cut off the output gear will
draw back, the whole start-up process is completed.
3.Technical Characteristic
This product is used under the working air pressure no more than
0.8MPa. maximum power 17KW. The main technical parameters at
different air pressure are as below:
Work air pressure MPa | 0.4 | 0.5 | 0.63 | 0.8 |
Max. output power KW | 7 | 9 | 12 | 17 |
Max output gear rotation r/min | 1600 | 1730 | 1870 | 2030 |
Power output gear torque N.m | 42 | 50 | 64 | 80 |
Parameter air consumption L/s | 120 | 150 | 190 | 240 |
