Cylinder type variety, that how to correctly choose?

Cylinder should include the choice of what factors and conditions of the cylinder type variety, that how to correctly choose? It is learned, according to different requirements should choose different types of cylinder. Specific analysis is as follows: according to the work requirements and conditions, correct selection of the type of cylinder. For cylinder to travel no impact on the terminal phenomenon and impact noise should choose buffer cylinder; For light weight, choose the light cylinder; Required to install a space narrow and short journeys, optional thin cylinder; With transverse load, optional with guide rod cylinder; Brake precision demanding, choose the lock cylinder; Do not allow the piston rod rotation, optional with functions of stem not rotary cylinder; High temperature environment to choose heat cylinder; In corrosive environment, should choose the corrosion resistance of cylinder. In harsh environments such as dust, need piston rod out of the dust cover installation. Asked to choose when no pollution to oil or no oil lubrication cylinder, etc. Besides, there are some factors also affect the choice of the cylinder, mainly include the type of installation, the size of the force, the piston stroke and the rate of movement of the piston. ( ) Install form according to the installation location, purpose and other factors. In the general case, using the fixed type cylinder. When need to work with agencies continuous rotary, should choose the rotary cylinder. On the piston rod in addition to the linear motion, still need to make arc swing, choose shaft pin type cylinder. When have special requirements, you should choose the corresponding special cylinder. ( ) The choice of the size of the force that bore. According to the size of the load to determine the cylinder and output thrust and tension. General all press load theory required cylinder force equilibrium conditions, according to the different load rate of different speed selection, margin slightly make the cylinder and output force. Diameter is too small, the output power is not enough, but the diameter is too large, bulky equipment, increase cost, and increase the gas consumption, waste of energy. In fixture design, should try to use force, to decrease the size of the shape of the cylinder. ( ) Piston stroke and the use of occasions and agency's schedule, but generally not full stroke, to prevent the piston and cylinder head touching one another. Such as used for clamping mechanism, etc. , shall be computed according to the required schedule increase - Mm allowance. ( ) Mainly depends on the cylinder of the piston velocity is input into the compressed air flow, cylinder vent size and the size of the tube diameter. For high speed movement should be of great value. Cylinder speed is commonly - mm/s。 For high-speed movement of cylinder, should choose large diameter of the inlet pipe; In the case of load change, in order to get a slow but steady speed, can choose with throttling device or gas-liquid damping cylinder, easy to realize the speed control. Selects the throttle valve control cylinder speed note: horizontal cylinder driving load, recommend using exhaust throttle speed regulation; Vertical installation cylinder lifting load, recommended intake throttle speed regulation; Schedules required to avoid impact on the smooth movement at the end, should choose the cylinder with the buffer device.
