JB types and working principle of the cylinder

JB do reciprocating linear motion of the cylinder and do reciprocating swing two types. Do reciprocating linear motion can be divided into the single-acting cylinder, cylinder of double-acting cylinder, impact diaphragm cylinder and the cylinder. (1) the single-acting cylinder: only one end of the piston rod, air supply from one side of the piston can produce pressure and air pressure forces the pistons to generate thrust, by spring or self-respect to return. (2) : double-acting cylinder from the pistons alternately on both sides of the gas supply, power output in one or two direction. (3) the diaphragm cylinder: replace with diaphragm piston, output force in only one direction, with a spring return. It sealed performance is good, but short. (4) the impact cylinder: this is a new type of component. It put the compressed gas pressure can be converted to the piston velocity ( ~ m/s) The kinetic energy of moving to do work. (5) the rodless cylinder: no the floorboard of the piston rod of the cylinder. Magnetic cylinder, the cable's cylinder two kinds big. Do reciprocating swing oscillating cylinder cylinder said, the blade will be divided into two, its inner cavity to two cavity alternating gas supply, output shaft do swing motion, oscillating Angle is less than °. In addition, there is the rotary cylinder, gas-liquid damping cylinder, and the step cylinder, etc. According to the size of the work force needed to determine the thrust and tension on the piston rod. In order to select the output force should make the cylinder when the cylinder is slightly allowance. If picked the small cylinder diameter, the output power is not enough, the cylinder does not work; But the diameter is too large, the device not only heavy, high cost and the gas consumption increases at the same time, cause energy waste. In fixture design, should as far as possible the power mechanism, in order to reduce the size of the cylinder. JB output calculation formula of cylinder theory: theory of output force (F: cylinder kgf) F ': when efficiency as % of output force ( kgf） ——( F′= F×%) D: the cylinder bore ( mm) P: working pressure ( kgf / C㎡) Example: mm cylinder diameter, working pressure of KGF/cm, its theoretical output force? How much is the bud output force? Connect P, D, and find out the points on the F, F ', too: F = KGF; F '= KGF choose cylinder bore during engineering design, can according to the theory of the use of pressure and thrust or pull, the size of the table - were found from experience. Example: they use a cylinder pressure of KGF/cm, launched its thrust for the cylinder KGF, ( Cylinder efficiency as %) Q: how to choose the cylinder bore? Thrust KGF by cylinder and cylinder efficiency %, the theory of the cylinder thrust may be calculated as F = F '/ % = ( kgf) By using the pressure KGF/cm and the theory of the cylinder thrust, found to choose bore for the cylinder can satisfy the use requirement.
