Introduction to the Working Principle and Types of Comosheng Cylinder in Italy

Operating Principle and Type Selection of Comosheng Cylinder in Italy
The working principle of CAMOZZI cylinder in Comosheng, Italy: The thrust and pull force on the piston rod are determined according to the force required. Therefore, when choosing the cylinder, the output force of the cylinder should have a little margin. If the cylinder diameter is small, the output force is insufficient, the cylinder can not work properly; but if the cylinder diameter is too large, not only makes the equipment heavy, high cost, but also increases the gas consumption, resulting in energy waste. In fixture design, force amplifier should be used as far as possible to reduce the size of cylinder. The following is the formula for calculating the theoretical output of the cylinder:
F: Cylinder theoretical output force (kgf) F': output force (kgf) - - (F'= F * 85%) D: Cylinder diameter (mm) P: working pressure (kgf / cm2) at 85% efficiency
Example: When the cylinder diameter is 340mm and the working pressure is 3kgf/cm2, how much is its theoretical output force? How much is the bud output force? Connect P and D, find out the points on F and F', and get:
F = 2800 kgf; F'= 2300 kgf, when choosing the cylinder diameter in engineering design, can be found from experience Table 1-1 according to the use pressure and theoretical thrust or tension.
Example: There is a cylinder whose working pressure is 5 kgf/cm2. When the cylinder is launched, its thrust is 132 KGF (cylinder efficiency is 85%). Question: What size of cylinder diameter should be chosen?
The theoretical thrust of the cylinder can be calculated as F=F'/85%=155(kgf) from the thrust of the cylinder 132 KGF and the efficiency of the cylinder 85%.
According to the theoretical thrust of the cylinder and the pressure of 5kgf/cm2, it is found that the cylinder with diameter of? 63 can meet the requirements of operation.
Categories of Cylinder I in Comosheng, Italy
In pneumatic transmission, the pressure energy of compressed gas is converted into the pneumatic actuator of mechanical energy. There are two types of cylinders, one is reciprocating linear motion and the other is reciprocating oscillation (see figure). Cylinders with reciprocating linear motion can be divided into single-acting, double-acting, diaphragm-type and impact cylinders.

(1) Impact Cylinder 2.2-9 Floating Joint Gas-liquid Damping Cylinder
The impact cylinder converts the energy of compressed air into the energy of high-speed motion of piston and piston rod, and uses this kinetic energy to do work. The impact cylinder can be divided into two types: ordinary type and fast type.
1) The structure of ordinary impact cylinder. Compared with the ordinary cylinder, the impact cylinder has a storage cylinder 1, a streamlined nozzle 4 and a middle cover 2 with an exhaust hole 3. Its working principle and process can be described as the following five stages.
The first stage: reset segment. Connect the air source, reset at the reversing valve, orifice A intake, orifice B exhaust, piston 5 under the action of pressure difference, overcome the sealing resistance and the weight of moving parts to move upward, with the help of the sealing rubber pad on the piston to seal the nozzle 4 on the middle cover. The annular space C between the middle cover and the piston passes through the exhaust orifice 3 to communicate with the atmosphere. Finally, the piston rod chamber pressure rises to the air source pressure, and the cylinder pressure drops to the atmospheric pressure.

The second stage: energy storage section. The reversing valve reverses, the B hole intake is filled into the storage cylinder chamber, and the A hole exhausts. Because the area of pressure acting on piston in cylinder chamber is only the area of nozzle 4, which is much smaller than that acting on piston with rod chamber pressure, the piston will not move until the following force balance equation is established. In style
D - diameter of middle cover nozzle (m); P30 - instantaneous pressure in cylinder chamber (absolute pressure) when piston begins to move (Pa); P20 - instantaneous pressure in rod chamber (absolute pressure) when piston begins to move (Pa);
G - Gravity (N), D - Piston Diameter (m), D1 - Piston Rod Diameter (m) of moving parts (piston, piston rod, hammer head die, etc.);
F&Twin; 0 - Instantaneous seal friction (N) when the piston begins to move.
