What are the classification standard cylinder

Occupy the pneumatic cylinder for half of the market, to show the importance of the cylinder, cylinder type very much, today to give you a brief introduction of the classification of the standard cylinder. One, the single-acting cylinder single-acting cylinder that is spring pressure and the spring pressure. Cylinder has simple structure, less gas consumption. The spring installed in the cylinder body and shorten the effective stroke of the cylinder, but spring has the ability of absorbing kinetic energy, can reduce stroke terminal impact effect. Generally used for short trips, to output force and speed requirement is not high. Second, double-acting cylinder can choose according to need. If a cylinder with no buffer device, when the piston moves to the terminal, especially travel long cylinder, piston impact force of end cover is very big, easy to damage the parts. Three air cushion, air cushion cylinder cylinder is within the cylinder body set up air buffer device. Four, with magnetic cylinder cylinder with magnetic switch is installed on the magnetic switch cylinder cylinder from the outside. Cylinder can be various types of cylinder, the cylinder must be weak magnetic conductivity, magnetic materials, such as aluminum, stainless steel, brass, etc. On the piston of non-magnetic body installation of a permanent magnet magnetic ring, with the piston moving magnetic ring close to switch, two reed of the reed switch is magnetized and attract each other, get an electric shock. When the circular move switch, reed excitation-loss, off contact. Get an electric shock signals during a make or break, Or the electrical signals disappear) , control solenoid valve to finish switching action accordingly. The characteristics of the magnetic switch, magnetic switch to detect the location of the cylinder stroke cylinder, don't need to travel at both ends mechanical control penalty ( Or the switch) And its mounting bracket, do not need to set collision block at the end of the piston rod, so easy to use, compact structure. High reliability, long life, low cost, fast switching response time, get the market and widely used.
