ATOS hydraulic cylinders are linear motion actuators whose output force is directly 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, and the output is linear motion speed and force. The piston of a hydraulic cylinder can complete 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 specific to the application, while the other devices are optional.

ATOS 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.

ATOS Cylinder Machining

As a key component of hydraulic cylinders, mining single-pillar supports, 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, with an internal surface roughness requirement of Ra 0.4–0.8 µm, and stringent requirements for coaxiality and wear resistance. A fundamental characteristic of cylinder barrels is deep-hole machining, which has always been a challenge for machinists. 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 the cylinder barrel's fatigue strength. Through roller burnishing, a work-hardened layer is formed on the surface, reducing the elastic and plastic deformation of the grinding pair contact surfaces, thereby improving the wear resistance of the cylinder barrel's inner wall and preventing burns caused by grinding. The reduced surface roughness after roller burnishing improves the fit.

The working principle of ATOS hydraulic cylinders is almost entirely similar. Take a manual jack as an example; a jack is essentially a simple hydraulic cylinder. Hydraulic oil is forced into the cylinder via a manual booster (hydraulic manual pump) through a one-way valve. Because of the one-way valve, the oil cannot flow back into the cylinder, forcing the cylinder rod upwards. During operation, hydraulic oil continues to flow into the cylinder, causing it to rise continuously. To lower the cylinder, the hydraulic valve is opened, allowing the oil to return to the tank. This is the basic working principle; other systems are improvements upon this. The principle of a pneumatic cylinder is essentially the same as that of a hydraulic cylinder.
