Before disassembling an ATOS hydraulic cylinder, proper preparation is essential. First, the hydraulic circuit must be depressurized; otherwise, when the oil pipe joints connected to the cylinder are loosened, high-pressure oil in the circuit will rapidly spray out. To depressurize the hydraulic circuit, first loosen the handwheel or pressure adjusting screw at the relief valve, etc., to unload the pressurized oil. Then, disconnect the power supply or power source to stop the hydraulic system.

First, to prevent bending or deformation of slender parts such as the piston rod, use wooden blocks for balanced support when placing them. During disassembly, avoid damaging the piston rod tip threads, oil port threads, piston rod surface, cylinder liner inner wall, etc.

Second, disassembly should be performed in sequence. Since the structure and size of various hydraulic cylinders differ, the disassembly sequence may vary slightly. Generally, the oil in both chambers of the cylinder should be drained, then the cylinder head should be removed, and finally the piston and piston rod should be disassembled. When disassembling the cylinder head of a hydraulic cylinder, special tools must be used for the retaining keys or rings of internal key-type connections; flat chisels are prohibited. For flange-type end caps, they must be pushed out with screws; hammering or prying is not allowed. If the piston and piston rod are difficult to remove, do not force them out; first determine the cause before disassembly.

Third, before and after disassembly, try to prevent the hydraulic cylinder parts from being contaminated by surrounding dust and impurities. For example, disassembly should be carried out in a clean environment; after disassembly, all parts should be covered with plastic sheeting, not cotton cloth or other work cloths.

Fourth, after disassembling the cylinder, carefully inspect it to determine which parts can continue to be used, which parts can be repaired and reused, and which parts must be replaced.

Fifth, all parts must be thoroughly cleaned before assembly.

However, it is important to install the sealing devices correctly. For example, when installing O-rings, do not stretch them to the point of deformation, and do not roll them in while installing; otherwise, they may become twisted and leak oil. All disassembled O-rings and dust rings should be replaced with new ones. Alternatively, when installing Y-shaped and V-shaped seals, pay attention to their installation direction to avoid oil leakage due to incorrect installation. For Y-shaped seals, the lip should face the pressurized oil cavity. Furthermore, for YX-shaped seals, distinguish between shaft and bore applications to avoid incorrect installation. V-shaped seals consist of support rings, sealing rings, and pressure rings of different shapes. When the pressure ring presses against the sealing ring, the support ring causes the sealing ring to form a seal. During installation, the opening of the sealing ring should face the pressurized oil cavity. When adjusting the pressure ring, only tighten it to prevent oil leakage, avoiding excessive sealing resistance.

Sixth, use a special wrench when tightening threaded connections, and ensure the torque meets standard requirements.

Seventh, after assembling the piston and piston rod, measure their coaxiality and straightness along their entire length to ensure they do not exceed tolerances.

Eighth, after assembly, the piston assembly should move smoothly without any resistance or unevenness.

Ninth, when installing the hydraulic cylinder onto the main unit, a sealing ring must be added between the inlet and outlet oil ports and tightened securely to prevent leakage.

ATOS cylinders, also known as hydraulic cylinders, are linear motion actuators whose output force is proportional to the effective area of ​​the piston and the pressure difference across it. Their function is to convert hydraulic energy into mechanical energy. The input to a hydraulic cylinder is the flow rate and pressure of the fluid; the output is linear motion speed and force. The piston of a hydraulic cylinder can perform linear reciprocating motion, but the output linear displacement is finite. A hydraulic cylinder is an energy conversion device that converts hydraulic energy into reciprocating linear motion mechanical energy. A hydraulic cylinder basically consists of a cylinder barrel and cylinder head, piston and piston rod, sealing device, buffer device, and venting device. The buffer and venting devices are determined by the specific application, while the other devices are...

ATOS Cylinder Machining: As a key component of hydraulic cylinders, mining single-pillar supports, hydraulic supports, and gun barrels, the quality of its machining directly affects the lifespan and reliability of the entire product. Cylinder barrel machining requires high precision; its inner surface roughness must be Ra 0.4–0.8µm, and strict requirements must be placed on coaxiality and wear resistance. A fundamental characteristic of cylinder barrels is deep hole machining, which has always been a challenge for machining personnel. Roller burnishing is employed, as the surface layer retains residual compressive stress, which helps to close micro-cracks and hinders the propagation of corrosion. This improves surface corrosion resistance and delays the initiation or propagation of fatigue cracks, thus increasing the fatigue strength of the cylinder barrel.
