        Croatia stroke adjustable cylinder

        (Croatia stroke adjustable cylinder,produced by Hengyu Hydraulic Co., Ltd)

        stroke adjustable cylinder are widely used in Croatia,because of no need for deceleration device,long service life,smooth movement.So our company has designed stroke adjustable cylinder for customers from Croatia.

        Introduction to stroke adjustable cylinder:

        The stroke adjustable cylinder should be vented: when the stroke adjustable cylinder is installed or parked for a long time to work again, the air will penetrate into the stroke adjustable cylinder and the pipeline system. In order to prevent the abnormal phenomenon of crawling, noise and heating of the actuator, the air in the stroke adjustable cylinder and the system should be discharged. In order to facilitate the removal of air deposited in the stroke adjustable cylinder, the oil is best entered and discharged from the highest point of the stroke adjustable cylinder. stroke adjustable cylinders that require higher motion stability are often equipped with exhaust plugs at both ends. Before working, unscrew the exhaust plug to make the piston go back and forth several times without load in the whole stroke, and the air can be discharged through the exhaust plug. After the air is drained, tighten the exhaust plug before working.

        When the stroke adjustable cylinder is customized, if there are high requirements for the quality of the stroke adjustable 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 stroke adjustable 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 stroke adjustable cylinder and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the matching property.

        The stroke adjustable cylinder should be used correctly and maintained regularly. The stroke adjustable cylinder should be deflated before use, the buffer regulating valve should be adjusted to a reasonable position, the cleanliness of the oil should be checked regularly, the dust on the stroke adjustable cylinder should be cleaned regularly, and attention should be paid to waterproof and fireproof.

        The pressure of the sliding surface of the stroke adjustable cylinder piston is too large, resulting in sintering. The piston tilts due to the weight of the piston rod, resulting in the phenomenon of non-stiffness, or the pressure of the sliding surface of the piston rises due to the action of the transverse load, which will cause sintering. In the design of the stroke adjustable cylinder must study its working conditions, the length of the piston and bushing and the size of the clearance must be fully paid attention to.

        Answers to some questions about stroke adjustable cylinder:

        What are the differences between hydraulic cylinder and pneumatic cylinder, what are their advantages and disadvantages?
        Hydraulic Cylinder: small body and large force, constant speed and variable speed (easy to change), the adjustment of output is also convenient, and the degree of freedom of transmission is high. However, maintenance costs and installation costs are high, and there is the trouble of mild oil pollution. Pneumatic Cylinder: easy to control, low price, easy access to energy. But the force is small, and can not achieve the effect of stable speed. The gas-liquid pressurized cylinder has the advantages of both of the above: environmental protection and energy saving, easy control, and simple adjustment. However, the output of the trip has certain restrictions, so it is more suitable for short trips, large output, but also environmental protection and energy saving and low configuration of the occasion. Because the pressure used in the pneumatic system is generally in the range of 0.2-1.0Mpa, the cylinder is not suitable for high power component.

        How to determine the rated working pressure of the hydraulic cylinder?
        Under normal circumstances, the working pressure is determined according to the size of the load and the installation space (the allowable diameter of the cylinder). In some special occasions, the smaller the cylinder, the better, the pressure level must be increased. The cylinder pressure is related to the estimated cost. The higher the pressure, the thicker the wall, the higher the cost, but conversely, the lower the pressure, the larger the diameter of the cylinder (when the same thrust) is required, the same high cost. Therefore, the rated pressure of the cylinder is concentrated in about 35 mpa, taking into account the cylinder diameter and wall thickness.
