Selection analysis cylinder seal support material selection analysis cylinder cylinder seal support materials are the main components of construction machinery to perform many actions done by the cylinder. Bearing bushing material greatly affect the quality of the double-acting hydraulic cylinder to cylinder superior quality, commonly used for the support of non-metallic materials are nylon bushing 1010 and POM. Bearing bushing assembly parts and assembly space 1. support bushing fitted in the guide sleeve (ductile materials) inside diameter of the recess of the working principle of double-acting hydraulic cylinders, piston rod serves as a guide and a support role, its inner diameter and outer rod best design gap diameter of 0.08-0.16mm. 2. The outer diameter of the bearing bushing in contact with the fuel tank cylinder diameter, the best design gap 0.1-0.19mm. When less than 0.1mm professional production of single-acting hydraulic cylinders, piston motion resistance increases, can not maintain uniform motion, the more obvious the oil temperature is high. Bush will not achieve the support role on the baffle rod or piston easy to scratch the outer cylinder wall, leading to serious cylinder scrapped. Piston hydraulic cylinder piston works only one-way movement, the movement in the opposite direction from the force required to complete. But its stroke hydraulic cylinder piston generally more big. Hydraulic cylinder piston rod can be divided into single and double rod two structures fixed by way of fixed and fixed two cylinder piston rod, according to the role of fluid pressure in the case of a single-acting and double-acting. In a single-acting hydraulic cylinder, the pressure oil chamber is for a hydraulic cylinder, by hydraulic pressure of the cylinder to achieve a single direction of movement, the movement in the opposite direction by an external force (e.g. spring force, its own weight or external loads, etc.) to achieve; and bis acting hydraulic cylinder piston movement in both directions through the two chambers alternately into the oil, by the action of hydraulic pressure to complete. Single-pole double-acting hydraulic cylinder piston. There is only one side of the piston rod, and thus the effective role of different areas of the two chambers. Are the same, different chamber into the oil, the piston velocity at different fuel supply; load force to be overcome in the same, different chamber into the oil hydraulic cylinder, the required supply pressure of different, or after it is set in the system pressure , sanitation garbage truck hydraulic cylinder movement in both directions to overcome load power supply different single-acting hydraulic cylinders, hydraulic mass-velocity (certified), Ninghe hydraulic cylinders supplied by Dezhou City mass-velocity hydraulic machinery factory.
