Hydraulic cylinder (referred cylinder) is commonly used in the hydraulic system components in the hydraulic system actuators from the role of other components such as pumps, valves, filters and other accessories are all supporting services for the hydraulic cylinder, cylinder hydraulic control system as The ultimate executive body, in machinery and equipment plays a very important role. So how to properly use hydraulic cylinders to become of particular concern. The following brief explanation on this issue. Mainly by the cylinder the cylinder, piston rod, piston, cylinder head, the cylinder end, seals, attachments, etc., of which the cylinder, piston, piston cylinder called Big Three. The main factors affecting the quality of the cylinder has three: experience in the design, processing quality, use and maintenance conditions. (A) design experience an engineer experienced in the design of hydraulic cylinders, you must know the following parameters: A. Bore, rod diameter, stroke B. Working pressure or tank load C. Operating temperature D. Working medium E. Operating speed F. Other parameters, such as connection type, installation size bore, rod diameter, stroke try to rely on national standards or other standards, avoid using non-standard size, or increase the difficulty of processing and manufacturing costs. Determined according to the length of the cylinder stroke length of the guide. According to the working pressure or load checking cylinder, piston, the strength of the screws. Meanwhile the working pressure, ambient temperature, the working medium, the operating speed is a key election set the seal. (Two) precision machining accuracy depends on the hydraulic cylinder level of equipment, production technology and testing methods. Cylinder, there are two commonly used processing methods, one is rough boring - fine boring - rolling, generally use 45 # seamless steel pipe, this method of processing quality is good, but the cost is high. Another method is to use cold drawn seamless steel pipe 20 #, and then honing costs than the bottom. Prior to processing must be quenched rod straightening, rod coating thickness is generally not less than 0.03mm. Processing must be strictly in accordance with the piston seal groove dimensions handbook given tolerance requirements. Now some manufacturers to reduce costs, the piston rod is not quenched, rod coating is not enough to reach the cylinder finish, guide sleeve without the use of copper, ductile iron instead, although the cost is reduced, but the quality of the hydraulic cylinder undesirable. (Three) cases using hydraulic cylinders to maintain fully meet user requirements, in addition to the above two factors, another point is to the proper use and regular maintenance. Cylinder deflated prior to use, to be transferred to a reasonable cushion valve position, to regularly check the cleanliness, the dust on the tanks cleaned regularly, in addition to pay attention to water and fire.
