P55557-3 Air Cylinder Drilling Rig Spare Parts 8 Position Type Pneumatic Cylinder
8 Position Pneumatic Cylinder description of Drilling Rig Spare
Parts
The eight-bit shift cylinder is the main shift drive component for
the large workover or other heavy equipment operation and walking,
and the compressed air source of the piston and all levels of stop
rings are achieved through the operation of the eight-bit shift
valve. In a circuit system composed of the cylinder and the shift
valve, the shift valve is the control element and the shift
cylinder is the actuator element. The structural principle of the
shift cylinder is shown in the figure. The cylinder has a piston
14, six stop rings 11,12,13,16,17,18,2, and 11,12,13 on the pull
rod 2; the large springs 6 and small spring 7 press the front
spring seat 8, the spring seat 8 is the seat stop ring 11, the stop
rings 11,12,13 are close to the piston 14.When there is no air
pressure inside the shift cylinder, the outer springs 6, inner
spring 7 and the piston 14 are force balanced by the stop rings
11,12,13 spring 10 and rest in the illustrated position.In the part
of the piston rod extending out of the cylinder block, with the
position scale of each gear, the current stop ring and piston
position is the empty unit position of the shift cylinder. The stop
rings 16,17 are set on the rod 20,18 fixed to the rod 20 with no
pressure entering, when the shift cylinder is neutral, they may be
in any position within the respective range of movement. The
eight-bit shift cylinder has eight inlet holes, and the position,
name of the 1A,6A,3A,3, 2, 5, 3, 6, 1, inlet, and the input air
pressure action are shown in Fig
