What type of cylinder do you have?
1) from the cylinder piston to withstand the pressure of gas is one-way or two-way classification (1) single acting cylinder: the piston of the cylinder can only be one-way pressure driven, reverse need to use external force. (2) double acting cylinder: the piston of the cylinder is driven by the air pressure in the two directions of both positive and negative directions. 2) classify the installation form of cylinder (1) fixed cylinder: cylinder block fixed. (2) axle pin type cylinder: the cylinder block can swing around the fixed axis pin at a certain angle. (3) rotary cylinder: the cylinder block is usually fixed on the main shaft of the machine tool, and can rotate with the main shaft of the machine. This kind of cylinder is usually used in the pneumatic chuck of the machine tool.
3) classify the functions and uses of cylinders (1) ordinary cylinders: single acting and double acting cylinders. This type of cylinder is generally used without special requirements. (2) buffer cylinder: the cylinder is equipped with a buffer device, which prevents the piston from striking when it moves to the end. This kind of cylinder is often used at higher pressure and higher speed. (3) air liquid damping cylinder: cylinder and hydraulic cylinder are connected in series, which can obtain more accurate movement speed. (4) swing the cylinder: the action of the cylinder revolves around the axle line. It can be used for the jig shift, valve switch and so on. (5) impact cylinder: it is a high energy cylinder with high impact force formed by piston rod. It can be used for punching, cutting and so on.
1. straight line type: the advantage lies in the simple structure, the cost is low, therefore the small displacement mostly uses the straight line, the inferiority lies in the vibration is bigger.2.V: the advantage is that the structure is compact, the stability is good, the disadvantage lies in the straight line type expensive, suitable for large displacement.3. flat (arrangement can be regarded as V type 180 degree angle): the advantage of ultra low center of gravity, high speed, good stability, the disadvantage is that there are only two car plants in this way: Porsche and Subaru.
