(2) The piston rod top thread, oil port and piston rod surface, cylinder liner inner wall, etc. should be prevented from being damaged during disassembly. In order to prevent bending or deformation of the elongate member such as the piston rod, a balance of wood support is applied when placing.
(3) The removal should be performed in sequence. Because the structure and size of various hydraulic cylinders are not the same, the disassembly sequence is slightly different. Generally, the two-chamber oil should be drained, then the cylinder head removed, and finally the piston and piston rod removed. When disassembling the cylinder head of a hydraulic cylinder, special tools are used for the card key or snap ring of the internal card key type connection. The use of a flat spatula is prohibited. For the flange type end cap, it must be screwed out. Hammering or hard hammering is not allowed. . When pistons and piston rods are difficult to withdraw, they must not be forcibly ejected. They should be identified and disassembled.
(4) Before and after unloading, try to create conditions to prevent the parts of the hydraulic cylinder from being contaminated by dust and impurities around it. For example, it should be done in a clean environment as far as possible; all parts should be covered with plastic cloth after disassembly, and do not cover with cotton cloth or other working cloths.
(5) After the cylinder is disassembled, it must be checked carefully to determine which parts can be used continuously, which parts can be used after repairs, and which parts must be replaced.
(6) The parts must be carefully cleaned before assembly.
(7) Correctly install the seals in various locations. 1 When installing the O-ring, do not pull it to the degree of permanent deformation, do not roll the edge of the suit, otherwise it may leak due to the formation of a twist. 2 When installing the Y-shaped and V-shaped sealing rings, pay attention to the installation direction to avoid oil leakage due to the installation. For Y-ring seals, the lip of the Y-ring seals against the pressure of the oil chamber; in addition, the Yx-ring seal must also be used to distinguish between the shaft and the hole. Do not install the wrong seal. The V-shaped seal ring is composed of a support ring, a seal ring and a pressure ring with different shapes. When the pressure ring presses the seal ring, the support ring can make the seal ring come into shape and seal. When installing, the open face of the seal ring should be faced. Pressure oil chamber; when adjusting the pressure ring, it should be limited to no leakage, and it must not be too tight to prevent excessive seal resistance. 3 If the sealing device is fitted with a sliding surface, it should be coated with an appropriate amount of hydraulic oil. 4 After the removal of the O-ring and dust ring should be completely replaced.
(8) A special wrench should be used when tightening the threaded connection. Torque should meet the standard requirements.
(9) After assembling the piston and the piston rod, it is necessary to measure whether the coaxiality and straightness over the entire length are excessive.
(10) After assembly, the piston assembly should be free from blockage and uneven resistance.
(11) When the hydraulic cylinder is installed on the mainframe, a seal must be added between the inlet and outlet port joints and tightened to prevent oil leakage.
(12) When assembled as required, several reciprocating motions should be performed at low pressure to eliminate cylinder gas.
