Nigeria hydraulic cylinder,servo cylinder manufacturer,servo cylinder
(Nigeria servo cylinder,produced by Hebei Hengyu company）
servo cylinder are widely used in Nigeria，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed servo cylinder for customers from Nigeria.
When producing oil servo cylinders, there are two processing processes, grinding and rolling, the latter is better than the former. Rolling machining is a kind of non-cutting machining, using the plastic deformation of the metal at room temperature, so that the micro roughness of the workpiece surface is flattened to achieve the purpose of changing the surface structure, mechanical characteristics, shape and size. Therefore, this method can achieve the two purposes of finishing and strengthening at the same time, which can not be done by grinding.
Causes and countermeasures of oil servo cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the servo cylinder will lead to premature wear of the piston seal, replace the piston seal; If the servo cylinder is visibly scarred, the servo cylinder must be replaced. It can be pressurized at one end of the servo cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most servo cylinder piston drift may not come from the servo cylinder, the above method to determine the servo cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.
The oil servo cylinder is a part of the hydraulic system, in the hydraulic system, to reasonably design the heat dissipation system, to prevent the oil temperature is too high is the key to keep the hydraulic oil temperature normal. The temperature of the system should be kept in a suitable range to reduce the energy released when the bubble bursts. While not affecting the normal circulation of the coolant, a certain amount of anti-corrosion additives can be appropriately added to inhibit rust. When operating the hydraulic system, we should strive to be stable, not too fast, too strong, and try to reduce the impact of hydraulic oil on hydraulic components.
How to repair the servo cylinder body when it is damaged: When the servo cylinder has trace deformation and shallow tensile marks, the servo cylinder is repaired by strong honing process. The heavy honing process can repair servo cylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the servo cylinder can meet the technical requirements.
How does the self-locking cylinder work?
Hydraulic cylinder self-locking is divided into oil self-locking and mechanical self-locking. The oil circuit itself is equipped with a valve to maintain pressure, so that the hydraulic oil of the cylinder does not return to the tank, and the oil chamber of the cylinder is filled with a certain pressure of oil. However, this pressure holding self-locking is not very safe and reliable, and the plunger will slowly return if there is a leak. Mechanical self-locking is to install a nut on the plunger of the cylinder, and when the cylinder rises to the required position, the nut on the cylinder plunger is rotated to the end, and the cylinder block is in contact, so that the plunger will be fixed to the required height. When it is necessary to relieve the pressure, screw the nut on again and let the plunger return to the position. This kind of cylinder has a special name, called self-locking hydraulic cylinder.
What diameter cylinder is needed for a force of 5 tons?
It depends on the pressure of your system pump. If the normal working pressure of the system is about 8MPa, then the diameter of the cylinder should be 100 mm.
