ATOS Hydraulic Cylinder Supply from Italy

The working principle of Italian ATOS hydraulic cylinder is to drive the piston to complete linear reciprocating motion through the input fluid flow rate and pressure, thereby converting hydraulic energy into mechanical energy.

ATOS hydraulic cylinder is a linear motion actuator whose output force is proportional to the effective area of the piston and the pressure difference on both sides. Its function is to convert hydraulic energy into mechanical energy. The input of a hydraulic cylinder is the flow rate and pressure of the fluid, and the output is the linear motion speed and force. The piston of a hydraulic cylinder can perform linear reciprocating motion, and the output linear displacement is limited. A hydraulic cylinder is an energy conversion device that converts hydraulic energy into mechanical energy for reciprocating linear motion. A hydraulic cylinder is basically composed of a cylinder barrel and cylinder head, a piston and piston rod, a sealing device, a buffering device, and an exhaust device. The buffer device and exhaust device depend on the specific application scenario.

The characteristics and functions of Italian ATOS hydraulic cylinders are as follows:

characteristic:

High precision machining: The ATOS hydraulic cylinder has excellent machining technology, which can improve surface roughness to Ra ≤ 0.08 μ m, correct roundness to ≤ 0.01mm, and increase surface hardness to HV ≥ 4 °, all of which make the hydraulic cylinder have higher precision and durability.

Long lifespan: Through rolling processing, residual compressive stress is left on the surface layer of ATOS hydraulic cylinders, which helps to close small cracks on the surface, hinder the propagation of erosion, thereby improving surface corrosion resistance and delaying the generation or expansion of fatigue cracks, thus improving the fatigue strength of the cylinder.

High reliability: The ATOS hydraulic cylinder has a simple structure and reliable operation. When used to achieve reciprocating motion, it eliminates the need for a deceleration device and has no transmission clearance, resulting in smooth motion. Therefore, it is widely used in various mechanical hydraulic systems.

Function:

Energy Conversion: ATOS hydraulic cylinders are hydraulic actuators that convert hydraulic energy into mechanical energy and perform linear reciprocating motion (or swinging motion).

Supporting function: ATOS oil cylinder is mainly used in places where heavy objects need to be supported for a long time. It can still support heavy objects even when the oil pressure is removed, and it is safe and reliable.

Widely used: ATOS hydraulic cylinders are commonly used in construction and agricultural machinery. For example, in large-scale projects, they are easy to operate, control, and self-locking jacks. They are designed with safety pressure protection devices and built-in pressure relief valves to prevent overload and protect the self-locking jacks for safe operation.

In summary, Italian ATOS hydraulic cylinders play an important role in various mechanical equipment due to their high precision, long lifespan, and high reliability.

The use and maintenance of Italian ATOS hydraulic cylinders mainly include the following aspects:

Pre installation inspection: Before installing the hydraulic cylinder into the system, the parameters on the cylinder label should be compared with the parameters at the time of ordering. The base of the hydraulic cylinder must have sufficient rigidity, otherwise when pressurized, the cylinder barrel will arch upwards, causing the piston rod to bend. The axial ends of the cylinder cannot be fixed. Due to factors such as hydraulic pressure and thermal expansion inside the cylinder, there is axial expansion and contraction. If the two ends of the cylinder are fixed, it will cause deformation of various parts of the cylinder.

Correct disassembly and assembly method: When disassembling and assembling hydraulic cylinders, it is strictly prohibited to use hammers to strike the cylinder barrel and piston surface. If there is damage to the cylinder bore and piston surface, it is not allowed to use sandpaper to polish, and it should be carefully polished with a fine oilstone. The clearance between the guide sleeve and the piston rod should meet the requirements. The hydraulic cylinder and surrounding environment should be clean. The fuel tank should be sealed to prevent contamination. The pipelines and fuel tanks should be cleaned to prevent the detachment of iron oxide scales and other debris. Cleaning should be done with a lint free cloth or specialized paper. Do not use hemp thread and adhesive as sealing materials.

Pay attention to oil temperature and oil pressure: The hydraulic oil should follow the design requirements, and pay attention to the changes in oil temperature and oil pressure. Unscrew the exhaust bolt for exhaust when unloaded.

Fault diagnosis and handling: The faults of hydraulic cylinders can be basically summarized as hydraulic cylinder misoperation, inability to push the load, and piston slip or crawling. For example, when the valve core is stuck or the valve hole is blocked, the contamination of the oil should be checked; When the piston rod and cylinder are stuck or the hydraulic cylinder is blocked, check whether the seal of the piston and piston rod is too tight, whether dirt and gum deposits have entered, etc.

Operation and maintenance specifications: In a single acting hydraulic cylinder, pressure oil is only supplied to one chamber of the cylinder, and the cylinder is moved in one direction by hydraulic pressure. The opposite direction of movement is achieved by external forces (such as spring force, self weight, or external load); In a double acting hydraulic cylinder, the movement of the piston in both directions is achieved through alternating oil injection into two chambers, relying on the action of hydraulic pressure.
