Jordan hydraulic cylinder,servo cylinder manufacturer,servo cylinder
(Jordan servo cylinder,produced by Hengyu Group）
servo cylinder are widely used in Jordan，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed servo cylinder for customers from Jordan.
Before the servo cylinder is removed, the relief valve should be loosened to reduce the pressure of the hydraulic circuit to zero, and then the power supply should be cut off to stop the hydraulic device. After loosening the oil port piping, the oil plug should be applied to plug the oil port.
The servo cylinder should be used as far as possible to avoid the transverse force, sometimes the piston rod to bear the transverse load is too large, especially do not force or pull the servo cylinder, bite. Elimination method: When installing the servo cylinder, ensure that the axis position of the servo cylinder is consistent with the direction of movement; Make the load borne by the servo cylinder as far as possible through the servo cylinder axis, to avoid the phenomenon of eccentricity.
The servo cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating motion (or swinging motion). It is simple in structure and reliable in operation. When it is used to achieve reciprocating movement, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth, so it is widely used in various mechanical hydraulic systems. The output force of the servo cylinder is proportional to the effective area of the piston and the pressure difference between the two sides; The servo cylinder is basically composed of servo cylinder and servo cylinder head, piston and piston rod, sealing device, buffer device and exhaust device. Buffer device and exhaust device depending on the specific application, other devices are essential.
Under normal circumstances, the servo cylinder is composed of the rear end cover, body, piston, piston rod and front end cover and other main parts. In order to prevent the working medium from leaking out of the servo cylinder or from the high pressure chamber to the low pressure chamber, a sealing device (sealing ring) is arranged between the servo cylinder and the end cover, the piston and the piston rod, the piston and the servo cylinder, the piston rod and the front end cover. A dustproof device is also provided on the outside of the front end cover. In order to prevent the piston from impacting the end cap when it moves rapidly to the end of the stroke, the end of the servo cylinder can also be provided with a buffer device. If necessary, the exhaust device should be set in order to exhaust.
Is it normal for the cylinder to turn black?
Cylinder blackening is a soft fault: 1. It does not affect the normal operation of your equipment. 2. Cylinder blackening involves a lot of things: hydraulic oil, oil seal material, piston rod coating, etc. These three things are not determined by the manufacturer because these three things are provided by other manufacturers. If the equipment is not due to high temperature caused by the black cylinder, you do not have to worry too much because your excavator can still work normally. If you feel uncomfortable, you can choose to replace the cylinder or replace the hydraulic oil.
How is the cylinder of hydraulic cylinder processed?
As the main parts of hydraulic cylinder, mining single pillar, hydraulic support, gun barrel and other products, its processing quality directly affects the life and reliability of the whole product. Cylinder processing requirements are high, the internal surface roughness requirements are Ra0.4 ~ 0.8&um, the coaxiality, wear resistance requirements are strict. The basic feature of cylinder is deep hole processing, which has always troubled the processing personnel. Due to the residual compressive stress on the surface of the surface layer, the rolling machining is helpful to seal the small cracks on the surface and prevent 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 cylinder can be improved.
