Structural principle of cylinder piston actuator
Structural Principle:
The cylinder is a hollow tubular structure that controls the flow of gas through valves, thereby achieving control of the piston's pushing and pulling torque. The piston is a cylindrical structure, usually located inside the cylinder and sealed against the cylinder wall. Valves are used to regulate gas flow in and out of the cylinder, providing torque when pushing the piston.
Working Principle:
The working process of a piston cylinder mainly includes three stages: intake, operation, and exhaust.
In the intake stage, compressed air or gas enters the cylinder from the air port, and the piston is pushed by the compressed air or gas and moves in a straight line along the cylinder wall.
During the working phase, the piston moves in a straight line along the inner wall of the cylinder to push external mechanical components for operation. At this point, the seal is tightly attached to the gap between the cylinder and piston, maintaining pressure inside the cylinder to prevent gas leakage.
During the exhaust phase, gas is discharged from the cylinder through the exhaust port, causing a decrease in internal pressure and the piston to return to its initial position. At this point, the seal is once again tightly attached to the gap between the cylinder and piston, maintaining pressure inside the cylinder.
