The single-acting cylinder has only one cavity to input compressed air to realize a one-way movement. Its piston rod can only be pushed back by external force, usually by spring force, diaphragm tension, gravity, etc.
Reset with spring force or diaphragm force, etc. Part of the compressed air energy is used to overcome the spring force or diaphragm tension, thus reducing the output force of the piston rod. Only one end enters (exhaust) air, the structure is simple, and the gas consumption is small. Springs, diaphragms, etc. are installed in the cylinder manufacturers, and the stroke is generally short. Compared with double-acting cylinders of the same volume, the effective stroke is smaller.
Precautions:
1. Requirements for air quality: Use clean and dry compressed air. Synthetic oil, salt, corrosive gas, etc. of organic solvents must not be contained in the air to prevent malfunction of cylinders and valves. Before installation. The connection piping should be fully flushed. Do not bring magazines such as dust, swarf, and sealing tape fragments into the cylinder and valve.
2. Requirements for the use environment: In places with a lot of dust, water droplets, and oil droplets, a telescopic protective cover should be provided on the side of the rod. During installation, no twisting state should occur. Where telescopic protective sleeves cannot be used, cylinders with strong dust rings or waterproof cylinders should be used.
3. If the ambient temperature and medium temperature of the cylinder exceed -10-60℃ with the magnetic switch and -10-70℃ without the magnetic switch, anti-freezing or heat-resistant measures shall be adopted.
4. In the environment of strong magnetic field, the cylinder with automatic switch of strong magnetic field should be selected. Standard cylinders must not be used in corrosive mists or mists that cause the sealing ring to swell.
