Rotary type: The air flow rate at which the pressure is lowered acts on the blade, thereby causing the rotor to rotate at a high speed to work. For example: dry grinding pneumatic tools; engraved pneumatic tools; pneumatic drills; pneumatic wrenches; wind batches; pneumatic hoists.
Pneumatic tools are devices that use the energy of compressed air supplied by an air compressor to operate as a source of power.
According to its basic working mode, it can be divided into: 1) Rotary (eccentric movable vane type). 2) Reciprocating (volumetric piston type)
(1) Rotary type: The air flow rate when the pressure is lowered acts on the blade, thereby causing the rotor to rotate at a high speed to work. For example: dry grinding pneumatic tools; engraved pneumatic tools; pneumatic drills; pneumatic wrenches; wind batches; pneumatic hoists.
(2) Reciprocating type: The compressed air is introduced into the cylinder, and the piston is reciprocated to work by controlling the intake port and the exhaust port. For example: gas saw; gas picking; pneumatic rivet gun; pneumatic pick; pneumatic hammer.
