Cylinder working principle and characteristics

Single-acting cylinder only one cavity type compressed air, to implement a direction. The piston rod can only help them back; Usually with the aid of the spring force, diaphragm tension, gravity, etc. The characteristics of the single-acting cylinder is: only one end into the ( Row) Gas, simple structure, small gas consumption. Single-acting cylinder only one cavity type compressed air, to implement a direction. The piston rod can only help them back; Usually with the aid of the spring force, diaphragm tension, gravity, etc. A, the characteristics of the single-acting cylinder is:, only one end into the ( Row) Gas, simple structure, small gas consumption. , with a spring or diaphragm forces, such as reset, part of the compressed air energy used to overcome the spring force or tension of diaphragm, and thus reduced the losing of the piston rod. , installed in cylinder spring, diaphragm and so on, generally shorter trip; Compared with the same volume of double-acting cylinder, effective stroke. , cylinder reset spring, the tension of the diaphragm are changing with the deformation size, as a result the output force in the process of travel of the piston rod is changing. As a result of above characteristic, single-acting piston cylinder used for short trips. The thrust and speed requirements is not high occasions, such as gas lifting, positioning and clamping device. Single-acting piston cylinder is not available in the occasion of long stroke, high load. Second, double-acting cylinder double-acting cylinder refers to two cavity can input the compressed air, respectively, the two-way movement of the cylinder. The structure can be divided into double piston rod, piston rod single, double piston, buffer and the buffer, and so on. The most widely used such cylinder. Double double rod double-acting cylinder piston rod cylinder has two kinds of fixed cylinder body and the piston rod is fixed. Fixed cylinder body, the load they carry ( If the workbench) Become an organic whole repeatedly with two cylinder piston rod, the compressed air into the cylinder in turn two cavities ( A chamber inlet another cavity exhaust) , the piston rod movement around the workbench, the workbench movement range is equal to its effective stroke s times. Installation of the space is large, generally used for small devices. When the piston rod is fixed, convenient for connection, made hollow piston rod, cylinder and load ( The workbench) Become an organic whole repeatedly, the compressed air from the right side or left side of the piston rod into the hollow cylinder two cavity, the cylinder drives the workbench to the left or to the left movement, the movement of the workbench range for its effective stroke s times. Suitable for medium and large equipment.
