Italy unidirectional cylinder

(Italy unidirectional cylinder,produced by Hengyu Group)

unidirectional cylinder are widely used in Italy,because of excellent temperature resistance,no transmission clearance,simple structure and reliable operation.So our company has designed unidirectional cylinder for customers from Italy.

Introduction to unidirectional cylinder:

The assembly work of the unidirectional cylinder has a great impact on the quality of the unidirectional cylinder: each part must be carefully cleaned before assembly; To correctly install the sealing device everywhere: when installing the sealing ring, pay attention to its installation direction to avoid oil leakage due to installation, and its lip should be equipped with a pressure oil chamber. In addition, because it is a YX-shaped sealing ring, it is necessary to pay attention to distinguish between shaft and hole use, do not install wrong; Because the sealing device is matched with the sliding surface, an appropriate amount of hydraulic oil should be applied during assembly; The special wrench should be used when the threaded coupling is tightened, and the torque should meet the standard requirements; After the piston and piston rod are assembled, it is necessary to measure whether the coaxiality and straightness on the full length are out of whack. After assembly, there should be no blocking sensation and uneven resistance when the piston assembly moves.

When the unidirectional cylinder is customized, if there are high requirements for the quality of the unidirectional cylinder, it is best to use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface of the small crack, preventing the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the unidirectional cylinder can be improved. By rolling forming, a cold working hardening layer is formed on the rolling surface, which reduces the elastic and plastic deformation of the contact surface of the grinding pair, thereby improving the wear resistance of the inner wall of the unidirectional cylinder and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the matching property.

When the piston speed of the unidirectional cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the unidirectional cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.

The unidirectional cylinder can not be used as grounding electrode to avoid electric damage to the piston rod.

Answers to some questions about unidirectional cylinder:

Can a leak in the cylinder cause the hydraulic system to fail?
Leakage in the cylinder can cause the hydraulic system to fail. Cylinder leakage (internal leakage) first affects the controlled action of the hydraulic system can not meet the requirements (such as the movement speed of the cylinder, the insufficient thrust and tension of the cylinder), if the internal leakage of the cylinder is too large, it may also cause the cylinder to be unable to promote the load movement. Second, the existence of internal leakage (internal leakage) of the oil cylinder will lead to the rapid rise (or too high) of the oil temperature of the hydraulic system, and the high oil temperature will not only waste the energy conversion of the system, but also lead to the reduction of the viscosity of the oil, which will accelerate the aging and destruction of the seals such as pumps, valves, cylinders, pipelines, and at the same time, the lubrication effect of the hydraulic oil is reduced, and the production of iron filings that increase the friction of the hydraulic system.

Slide weight 35 kg exit stroke 55mm, is it suitable to use 40 cylinder diameter cylinder?
The maximum output force of the 40-bore hydraulic cylinder can reach 2 tons, and whether it can be used depends on the use scenario. In addition, the problem of mechanism stuck has nothing to do with the size of the power source, and reasonable structural design and good machining and assembly accuracy are the key.
