(Britain yg series hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory）

yg series hydraulic cylinder are widely used in Britain，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed yg series hydraulic cylinder for customers from Britain.

Introduction to yg series hydraulic cylinder:

When the yg series hydraulic cylinder is customized, if there are high requirements for the quality of the yg series hydraulic 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 yg series hydraulic 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 yg series hydraulic cylinder and avoiding the burn caused by grinding. After rolling, the reduction of surface roughness value can improve the matching property.

Piston yg series hydraulic cylinder is widely used in hydraulic transmission. When the yg series hydraulic cylinder works, it mainly delivers hydraulic oil alternately to both sides of the piston in the yg series hydraulic cylinder, and uses the pressure difference of hydraulic oil on both sides of the piston to realize the reciprocating movement of the piston. If you want to speed up the forward speed of the piston, the return oil in the yg series hydraulic cylinder can be controlled by the valve and directly input into the inlet pipe to participate in the work of the piston to achieve rapid movement of the piston, but the thrust of the piston is reduced much.

Causes and countermeasures of oil yg series hydraulic cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the yg series hydraulic cylinder will lead to premature wear of the piston seal, replace the piston seal; If the yg series hydraulic cylinder is visibly scarred, the yg series hydraulic cylinder must be replaced. It can be pressurized at one end of the yg series hydraulic 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 yg series hydraulic cylinder piston drift may not come from the yg series hydraulic cylinder, the above method to determine the yg series hydraulic cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.

The yg series hydraulic 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 yg series hydraulic cylinder, bite. Elimination method: When installing the yg series hydraulic cylinder, ensure that the axis position of the yg series hydraulic cylinder is consistent with the direction of movement; Make the load borne by the yg series hydraulic cylinder as far as possible through the yg series hydraulic cylinder axis, to avoid the phenomenon of eccentricity.

Answers to some questions about yg series hydraulic cylinder:

How to calculate the tonnage of the hydraulic press without konowing the diameter of the cylinder?
To know the tonnage of the hydraulic cylinder, you first need to know the working pressure of the hydraulic system, the inner diameter of the hydraulic cylinder and the outer diameter of the cylinder rod (the outer diameter of the cylinder rod is needed when calculating the hydraulic cylinder tension). The thrust of the hydraulic cylinder (that is, the force that the hydraulic cylinder can produce by extending out) = the cross-sectional area of the hydraulic cylinder (or the cross-sectional area of the piston) × the working pressure of the cylinder (the cross-sectional area of the piston) =pi*D^2/4= PI (take 3.14) × the square of the cross-sectional area of the piston ÷4 working pressure to see the pressure displayed on the pressure gauge when the maximum load is working.

What is the clearance between the cylinder and the piston?
The gap between the cylinder and the piston in the radius is generally 40 wires, that is, about 0.4mm, and the gap of the cylinder with different diameters will be slightly different. Generally, the inner diameter of the cylinder is larger than the outer diameter of the piston, so as to prevent the friction between the outer surface and the inner surface of the cylinder during the operation of the piston. In order to ensure that the cylinder has a rod cavity and a rodless cavity seal, a sealing device, that is, a sealing ring, is installed on the outer surface of the piston. The sealing ring form is not exactly the same, the O-type sealing ring is generally used under low pressure, and the lip sealing ring is used under high pressure. At the same time, the outer circle of the piston is also equipped with a dust ring and a wear ring. As long as the cylinder seal fails, all the internal seals should be replaced.
