Cylinder model selection methods and steps

Often involved in the selection used in pneumatic cylinder, so need to pay attention to when doing cylinder type selection? The following simple introduce the methods and steps of cylinder under selection. Double-acting cylinder, for example, we introduce the double-acting cylinder selection process. 。 Selected according to the cylinder bore cylinder load condition, to determine the cylinder axial load F. According to the load state of movement, load rate of the primary cylinder eta. According to the air supply conditions, determine the use of cylinder pressure P. P should be less than % of the pressure reducing valve inlet pressure. Known F, eta and P, the single-acting cylinder, the default bar diameter and the ratio of the diameter d/d =. , according to the theory described earlier cylinder force calculation formula and the formula of load rate, can be selected bore D; Of double-acting cylinder, as well as using the above mentioned force calculation formula of cylinder theory and formula of load rate, can be selected bore D. The size of the cylinder diameter D should be standardized. 。 Selected cylinder stroke according to the operation of the cylinder distance and actuator stroke ratios of the primary cylinder stroke. For ease of installation and debugging, to calculate the trip should have appropriate allowance. Should choose as far as possible for the standard, can guarantee delivery speed, lower cost. 。 Selected varieties of cylinder will use the purpose and need to bore and stroke as a condition, choose the required from cylinder series varieties of gas cylinder. 。 Selected form different series have different installation form, and each series has a variety of installation forms to choose from, should according to the different USES of cylinder, to select the type of installation. Installation forms are: basic, foot type, rod side flange type, rodless side flange type, single type of earrings, double earrings, give ear rod shaft type, rodless incline shaft type, the central trunnion type. 。 Selected buffer forms in accordance with the purposes to need, choose the cylinder form of buffer. In the form of cylinder cushion: no buffer, rubber cushion, air cushion, hydraulic buffer. 。 Selection of magnetic switch installed on the cylinder of the magnetic switch, mainly for position detection. It is important to note: built-in circular cylinder, is the precondition that the use of magnetic switch. Magnetic switch installation forms are: steel belt installation, rail installation, pull rod installation, after installation.
