Advantages of ATOS Hydraulic Cylinders

ATOS hydraulic pumps, ATOS piston pumps, ATOS gear pumps

ATOS hydraulic cylinders are mainly used in applications requiring long-term support of heavy objects. They can continue to support heavy objects even after the oil pressure is removed, and are safe and reliable. They can be used underwater, are single-acting, have load retraction, and a self-locking nut for added safety. Especially in large-scale projects, they are easy-to-operate and self-locking jacks, designed with a safety pressure-holding device and a built-in pressure relief valve to prevent overload, protecting the self-locking jack for safe operation. The connection uses high-pressure hoses and threaded connectors, offering quick use and overcoming the leakage problems of traditional quick-connect fittings. They are mainly used in equipment installation, lifting, and dismantling operations in various industries such as power, construction, machinery manufacturing, mining, railway bridges, and shipbuilding.

Precautions for ATOS Hydraulic Cylinders;

Preparations should be made before disassembling the hydraulic cylinder. First, the hydraulic circuit must be depressurized; otherwise, when the oil pipe joint connected to the cylinder is loosened, the high-pressure oil in the circuit will spray out rapidly. 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 device from operating.

Next, begin disassembling the hydraulic cylinder.

First, to prevent bending or deformation of slender parts such as the piston rod, use wooden blocks for even support when placing it. 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 will also 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 removed. When disassembling the cylinder head, special tools should be used for internal key-type connections (keys or rings); 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, strive 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.

ATOS Cylinder Machining: As a major component of hydraulic cylinders, mining single-support pillars, hydraulic supports, and blasting barrels, the quality of the cylinder barrel's machining directly affects the lifespan and reliability of the entire product. Cylinder barrel machining requires high precision; its inner surface roughness must be Ra0.4～0.8µm, and strict requirements must be placed on coaxiality and wear resistance. A fundamental characteristic of the cylinder barrel is deep hole machining, which has always been a challenge for machining personnel. Roller burnishing, by leaving residual compressive stress on the surface layer, 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 cylinder fatigue strength. Through roller burnishing, a work-hardened layer is formed on the surface, reducing elastic and plastic deformation of the grinding surfaces, thereby improving the wear resistance of the cylinder inner wall and preventing burns caused by grinding. The reduced surface roughness after roller burnishing improves fit.

Advantages and disadvantages of ATOS cylinders:

1. Since pneumatic systems generally operate at pressures within the range of 0.2-1.0 MPa, pneumatic cylinders cannot be used as high-power power components in hydraulic cylinders. Hydraulic cylinders, however, can be used as higher-power components, or hydraulic cylinder systems can be employed.

2. Air is an inexhaustible medium, with no cost or supply difficulties. Used air can be directly discharged into the atmosphere, making disposal convenient and preventing contamination of hydraulic oil.

3. Air has lower viscosity, resulting in less resistance than hydraulic oil.

4. However, because air has a much higher compressibility than hydraulic oil, its operational smoothness and responsiveness are significantly inferior.
