Italy hydraulic cylinder,servo hydraulic cylinder manufacturer,servo hydraulic cylinder
(Italy servo hydraulic cylinder,produced by Hebei Hengyu company）
servo hydraulic cylinder are widely used in Italy，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed servo hydraulic cylinder for customers from Italy.
The wear of the hard chromium plating layer of the servo hydraulic cylinder is mostly caused by the grinding of the friction iron powder of the piston, and the wear is faster when there is water in the middle. Corrosion caused by the contact potential difference of the metal only occurs in the part of the piston contact, and the corrosion occurs in a point pattern. As mentioned above, when there is moisture in the middle, it will promote the development of corrosion. Compared with castings, the contact potential difference of copper alloy is higher, so the corrosion degree of copper alloy is more serious.
servo hydraulic cylinder hydraulic oil selection: The recommended working oil viscosity of the servo hydraulic cylinder is 10 ~ 110cSt (1.8 ~ 15E), ISO VG46 hydraulic oil. The normal working oil temperature is 10 ~ 70℃, and the ambient temperature is in the range of -20 ~ 80℃. When the ambient temperature and service temperature are low, the hydraulic oil with lower viscosity can be selected.
The servo hydraulic cylinder can not be used as grounding electrode to avoid electric damage to the piston rod.
The pressure of the sliding surface of the servo hydraulic cylinder piston is too large, resulting in sintering. The piston tilts due to the weight of the piston rod, resulting in the phenomenon of non-stiffness, or the pressure of the sliding surface of the piston rises due to the action of the transverse load, which will cause sintering. In the design of the servo hydraulic cylinder must study its working conditions, the length of the piston and bushing and the size of the clearance must be fully paid attention to.
How to calculate the cross-sectional area of hydraulic cylinder?
Hydraulic cylinder cross section integral rod cavity and rodless cavity: rod cavity is cylinder inner wall cross-sectional area - piston rod cross-sectional area; The rodless cavity is the cross-sectional area of the inner wall of the cylinder. If the working pressure p and the output force F are known, the effective cross-sectional area A=F/p can be calculated.
How many kinds of cylinder seal repair kit are there?
Very much, a wide variety of imported and domestic, J type, UHS, DHS, O-ring, Sterseal, etc., as well as support bars, materials are different, according to the size of the pressure selection is different, the appearance of the structure is different, the size is a variety, maintenance is generally selected according to the needs of the cylinder.
