Canada yg series hydraulic cylinder

(Canada yg series hydraulic cylinder,produced by Hengyu Group)

yg series hydraulic cylinder are widely used in Canada,because of no transmission clearance,powerful torque,clever hydraulic energy conversion.So our company has designed yg series hydraulic cylinder for customers from Canada.

Introduction to yg series hydraulic cylinder:

The internal leakage of the yg series hydraulic cylinder should be prevented when the yg series hydraulic cylinder is used. The internal leakage of yg series hydraulic cylinder includes the leakage caused by excessive wear of yg series hydraulic cylinder block seal, piston rod and seal cover seal and piston seal. The cause of sealing leakage between the piston rod and the seal cover is that the seal is wrinkled, squeezed, torn, worn, aging, deterioration, deformation, etc., and a new seal should be replaced at this time.

yg series hydraulic cylinder is the most important part of construction machinery, the traditional processing method is: broaching yg series hydraulic cylinder block - fine boring yg series hydraulic cylinder block - grinding yg series hydraulic cylinder block. The rolling method is: broaching yg series hydraulic cylinder block - fine boring yg series hydraulic cylinder block - rolling yg series hydraulic cylinder block, the process is 3 parts, but the time is compared: grinding 1 meter of the yg series hydraulic cylinder block is about 1-2 days, rolling 1 meter of the yg series hydraulic cylinder block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3 μm before rolling to Ra0.4 ~ 0.8μm, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the yg series hydraulic cylinder increases by 25%. If the yg series hydraulic cylinder life is only considered, it is increased by 2 to 3 times, and the boring and rolling process is 3 times more efficient than the grinding process In particular, if you want to make high-quality yg series hydraulic cylinders, you must take the rolling production process. After the yg series hydraulic cylinder is rolled, there is no sharp tiny edge on the surface, and long-term motion friction will not damage the seal ring or seal, which is particularly important in the hydraulic industry.

When the initial action of the yg series hydraulic cylinder is slow, please check the temperature of the hydraulic system, because in the case of low temperature, the viscosity of the hydraulic oil is large and the fluidity is poor, resulting in slow action of the yg series hydraulic cylinder. The improvement method is to replace the hydraulic oil with good viscosity temperature performance, and the oil temperature at low temperature can be increased by heater or heating by the machine itself, and the normal working oil temperature of the system should be maintained at about 40 ° C.

The definition of the minimum stable speed refers to the minimum movement speed of the yg series hydraulic cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the yg series hydraulic cylinder that undertakes different work has different requirements for the minimum stable speed.

Answers to some questions about yg series hydraulic cylinder:

Two cylinders have a reversing control, if the load of the two cylinders is not the same, how to ensure their synchronization?
The piston rod of the cylinder is required to extend synchronization: install A shunt collector valve or synchronous motor at port A of the direction control valve, and then connect the two outlets of the shunt collector valve to the rod-free cavity of the two cylinders respectively. It is required that the outlet of the diverter collector valve is connected to the rod cavity of the two cylinders respectively when the piston rod is withdrawn in synchronization. The synchronization performance depends on the quality of the diverter valve and the leakage of the hydraulic system.

Why does excavator cylinder oil leak?
Under normal circumstances, the leakage of hydraulic cylinders is divided into internal leakage and external leakage. The external leakage is generally due to damage to the oil seal at the extended end of the piston rod and needs to be replaced. Internal leakage is generally because the oil seal on the piston is damaged, you can try to replace the oil seal here, if the replacement will also leak, then check whether there is damage to the inner wall of the cylinder.
