(4) before unloading to try to create the conditions to prevent the discharge of hydraulic cylinder parts are dust and impurity contamination around. For example, should be demolished as possible in a clean environment; after the demolition of all the parts to use plastic sheeting to cover, do not use cotton or other work with a cloth cover. (5) After removing the hydraulic cylinder to be carefully examined to determine which parts can continue to use the fuel tank, which parts can be repaired before use, which parts must be replaced. (6) must be carefully cleaned before assembly of the parts. (7) around the sealing device to be installed correctly. ① When installing O-rings, do not pull their permanent deformation degree, it is not a hollow cylinder side scrolling side suits, or may form a distorted shape due to oil spills. ② when installing high-quality Y-shaped cylinder and V-ring, pay attention to the mounting direction to avoid spills installed instead. Y-shaped ring, its lips coping with pressure oil chamber; moreover, Yx-ring is also a distinction shaft or hole, do not install the wrong. V-ring shape different from supporting ring, seal rings and pressure rings, when the pressure ring compression seal ring, bearing ring seal ring can be generated as the sky-shaped seal, the seal ring should be installed for the opening pressure oil chamber; adjusting the pressure ring, should be limited so as not to leak, not too tight, sealed to prevent too much resistance. ③ sealing device such as a sliding surface fit, the assembly should be coated with an appropriate amount of hydraulic oil. O-ring seals and dust ring should be demolished after all the new ones ④. Analytical engineering machinery cylinder hydraulic cylinder output force and the effective area of ??the piston and the pressure is proportional to both sides of the linear motion-type actuator. Its function is the hydraulic energy into mechanical energy. Input hydraulic cylinder is a fluid flow and pressure, the output is linear velocity and force. Hydraulic cylinder piston to complete a linear reciprocating motion, the output of the linear displacement is limited. Consisting essentially of hydraulic cylinders and cylinder head, piston and piston rod, the sealing means, buffer means and exhaust composition. Rolling is a non-cutting cylinder manufacturer, at room temperature using a metal plastic deformation, so that microscopic surface irregularities or rolling so as to achieve the purpose of changing the surface structure, mechanical properties, shape and size. Therefore, this method can simultaneously achieve finishing and strengthen both purposes, is not able to do the grinding. Hydraulic cylinder manufacturers _ Lu (certified) _ cylinders supplied by Lu of hydraulic equipment plant in Texas. Texas Lu force hydraulic machinery plant (www.luliyeya.com) is a leader in Dezhou, hydraulic machinery and parts, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Lu Hydraulic leadership with the staff warmly welcome all inquiries negotiations to create Lu hydraulic force a better future.
