Pneumatics machine application is wide, each figure that large trade can see it. Ferial li of empty press that we see it is to producing a workshop mostly. A lot of people do not know to pneumatics machine also can be used in shipping travel process actually. Pneumatics machine applies in shipping: With compress air to blow except ark of a powerful person that understand the of great capacity, oil residue, , use as torpedo of tool of hooter, pneumatic blasts off, submarine submergence and rise. Still have the following use next: 1, machine of pneumatics of screw of the air that start compresses air to regard as those who start large derv engine is powerful and the sources of energy that can store. Although be air,use below the inferior pressure that is less than 150psi, but can use a space reasonably so with high-pressured force memory normally, still allow enough volume to be used at starting a trial for many times at the same time. 2, control, instrument and class action energy of life have a lot of systems and flow need to compress air on the boat. Engine arranges the system that monitor, solar term door is controlled, control a powerful person. Of course this is machine of the pneumatics on the boat compresses airy a few kinds in a lot of utility and application only.
