How to choose the cylinder

The selection of the cylinder 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 without oil. 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.
