(Costa Rica automatic reversing cylinder,produced by Hengyu Group）
automatic reversing cylinder are widely used in Costa Rica，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed automatic reversing cylinder for customers from Costa Rica.
When the automatic reversing cylinder is customized, if there are high requirements for the quality of the automatic reversing cylinder, it is best to use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface of the small crack, preventing the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the automatic reversing cylinder can be improved. By rolling forming, a cold working hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving the wear resistance of the inner wall of the automatic reversing cylinder and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the matching property.
The automatic reversing cylinder should not be mixed with foreign objects during assembly, which will cause scars. Before the total assembly of the automatic reversing cylinder, all parts must be fully removed and cleaned. When the parts are installed with burrs or dirt, foreign objects are easily embedded into the surface of the automatic reversing cylinder wall due to the stiffness and the weight of the parts, causing scars.
When the automatic reversing cylinder is installed, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the automatic reversing cylinder head, earring (or middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent rigid interference and cause unnecessary damage.
The automatic reversing cylinder should be used as far as possible to avoid the transverse force, sometimes the piston rod to bear the transverse load is too large, especially do not force or pull the automatic reversing cylinder, bite. Elimination method: When installing the automatic reversing cylinder, ensure that the axis position of the automatic reversing cylinder is consistent with the direction of movement; Make the load borne by the automatic reversing cylinder as far as possible through the automatic reversing cylinder axis, to avoid the phenomenon of eccentricity.
How to calculate hydraulic cylinder thrust?
Cylinder diameter = piston diameter =200MM Piston area =π (200/2) square =3140 square mm =31.4 square cm 25MPA=250KG/ square cm Maximum thrust = pressure * Piston area =250 *31.4 =7850KG=78500 Newtons This is the maximum thrust. The formula can be derived from the calculation formula.
Structural characteristics of the plunger cylinder? (1) The plunger hydraulic cylinder is a single-acting hydraulic cylinder, which can only move in one direction by hydraulic pressure, and the return trip of the plunger depends on other external forces or the weight of the plunger; (2) The plunger is only supported by the cylinder liner and is not in contact with the cylinder liner, so the cylinder liner is easy to process, so it is suitable for long stroke hydraulic cylinder; (3) the total pressure of the plunger during work, so it must have sufficient stiffness; (4) The weight of the plunger is often large, and it is easy to sag due to its own weight when placed horizontally, resulting in wear of the seals and guide side, so its vertical use is more favorable.
