France yg series hydraulic cylinder

(France yg series hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)

yg series hydraulic cylinder are widely used in France,because of no need for deceleration device,long service life,smooth movement.So our company has designed yg series hydraulic cylinder for customers from France.

Introduction to yg series hydraulic cylinder:

Classification of yg series hydraulic cylinder: according to the mode of movement it can be divided into linear reciprocating movement type and rotary swing type; According to the effect of liquid pressure, it can be divided into single acting type and double acting type. According to the structure, it can be divided into piston type, plunger type, multistage telescopic sleeve type, pinion and rack type, etc. According to the installation form can be divided into rod, earring, foot, hinge shaft and so on; According to the pressure grade can be divided into 16Mpa, 25Mpa, 31.5Mpa and so on.

The machining accuracy of the yg series hydraulic cylinder depends on the level of equipment, production technology and testing means. yg series hydraulic cylinder processing methods are commonly used in two ways, one is rough boring - fine boring - rolling, generally with 45# seamless steel pipe, this method of processing quality is good, but the cost is high. Another method is to use 20# cold-drawn seamless steel pipe, and then honing, the cost is lower. The piston rod must be adjusted and straightened before processing, and the coating thickness of the piston rod is generally not less than 0.03mm. The piston must be machined in strict accordance with the groove size and tolerance requirements given in the seal manual.

Before the yg series hydraulic 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 piston seal of the yg series hydraulic cylinder is the main element to prevent leakage in the yg series hydraulic cylinder. For the lip seal, it should focus on checking whether the lip edge is bruised and worn, and for the combination seal, it should focus on checking the wear of the sealing surface, and then determine whether the seal can be used. In addition, it is necessary to check whether the static seal between the piston and the piston rod is crushed. The piston rod seal should focus on checking the wear of the seals and supporting rings.

Answers to some questions about yg series hydraulic cylinder:

How to judge the failure of forklift hydraulic cylinder?
The common faults of the hydraulic cylinder of forklift truck are mainly crawling, insufficient thrust, working speed decline or even stop. Generally, crawling occurs at low speed. The main reason is that the air stored in the cylinder is not cleared. In addition, excessive or uneven mechanical friction can also cause crawling. Such as the piston and the piston rod different heart, the piston rod full length or local bending, the cylinder hole straightness is poor, the cylinder is drum shaped or has a large taper, the cylinder thin finish decline or produce hair, the cylinder installation accuracy is out of whack, the piston rod nuts at both ends of the screw too tight to make its concentricity is poor, the oil seal screw too tight friction is too large, will cause crawling.

How to select swing cylinder? Under what conditions are they designed and selected?
1, determine the system parameters: ① the weight and the required force; ② Nominal working pressure and range; ③ The time required to travel this distance; 4 oil medium 2, installation method: select the appropriate way for the specific application 3, cylinder diameter and working pressure: determine the cylinder diameter and provide the necessary force required by the system pressure 4, piston rod: determine the minimum piston rod diameter required to withstand the longitudinal bending force, select the appropriate piston rod end and piston rod end thread 5, piston: Whether the seal type is suitable for the application 6, buffer: choose the buffer requirements as appropriate.
