What is the standard cylinder pressure in general?
1. First, make a rough calculation based on the rated gas pressure and the standard cylinder bore.
For example: air pressure 0.5Mpa (5.0985811 kgf/square centimeter (kgf/cm2)), cylinder diameter 50mm (5cm), cylinder cross-sectional area=pi*(5/2)^2=19.63 (square centimeter)
Therefore, the theoretical output under 0.5Mpa=5.0985811*19.63=100.085 (kg force)
However, it is only a theoretical output, and the actual efficiency will be lower according to the working conditions.
2. Rodless cavity cross-sectional area * working air pressure = piston thrust A, rod cavity cross-sectional area * working air pressure = piston return force, the normal working pressure designed for common pneumatic components is 0.4 MPa, the most common air compressor The output pressure is 0.4-0.7 MPa, the reasoning required to push a 700kg workpiece needs to be tested, and the piston stroke should be determined according to the needs.
The five common installation methods of standard cylinders are: middle pendulum type, free type, flange type, earring type and tripod type.
Their fixing methods are as follows:
1. The middle pendulum type installation method is to install the TC middle pendulum in the middle of the cylinder to complete the installation and fixation of the cylinder. The cylinder of this installation method can swing around the middle trunnion and is suitable for long cylinders.
2. Free installation method refers to the use of the thread in the cylinder body to screw into the machine body for fixed installation without the use of installation accessories; or the use of the thread on the outside of the cylinder body and the nut to fix the cylinder on the machine; The screw holes of the cover are fixed on the machine with screws.
3. Flange type installation can be divided into front flange type and rear flange type. The front flange type uses flanges and screws to fix the cylinder at the front cover, and the rear flange type refers to the installation method at the rear cover. The flange is fixed with screws, which is also suitable for occasions where the load movement direction is consistent with the axis of the piston rod.
4. The earring type installation method is divided into single ear type and double ear type, which means that the cylinder end cover and earring type installation accessories are fixed together with screws at the rear cover of the SC series standard cylinder. The vertical direction of the piston rod axis is The cylinder of the pin hole, the load and the cylinder can swing around the pin. During rapid movement, the greater the swing angle, the greater the lateral load on the piston rod.
5. Tripod type installation method, denoted by LB, means to use an L-shaped mounting tripod to fit the screw holes at the front end cover and use screws for installation and fixation. The mounting tripod can bear a large overturning moment and can be used for loads. When the direction of movement is consistent with the axis of the piston rod.
