(Canada stacker cylinder,produced by Hengyu Group）

stacker cylinder are widely used in Canada，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed stacker cylinder for customers from Canada.

Introduction to stacker cylinder:

The coordination of the sliding parts of the stacker cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.

If it is found that the stacker cylinder lubrication is poor or the stacker cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the stacker cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the stacker cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the stacker cylinder center line. In this way, when the piston works in the stacker cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the stacker cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

We can not just consider the price and ignore the quality when we purchase the stacker cylinders. Now some manufacturers produce unqualified products in order to reduce costs, the piston rod is not adjusted, the rod coating is not enough, the stacker cylinder finish can not reach, the guide sleeve should use copper, but instead of ductile iron, although the cost is reduced, the quality of the stacker cylinder is not required.

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

Answers to some questions about stacker cylinder:

Why is the cylinder not in place when the concrete pump truck changes the piston?
When the concrete pump truck changes the piston, the cylinder is not in place mainly because the transfer oil connecting the two cylinders is not completely drained. Sany and Zhonglian have a piston return switch, which can be used to back the piston to the cleaning tank. The elephant is equipped with a stop valve at the bottom of the oil cylinder, usually in the closed state, when opened, the piston can be returned to the cleaning tank, remember to close the valve after the piston is updated.

Why does the hydraulic cylinder not return?
For a spring return cylinder, it is possible that 1, the spring is damaged. You can check it for processing. 2, the oil in the oil path is not unloaded, causing it to be unable to reset. 3, the cylinder piston is dead, resulting in no position. For double-acting cylinders, it is possible to: 1, the spool is not reversed, or is not changed to the correct position, check whether the reversing valve is normal (and whether there is electricity). 2, the cylinder piston is dead, resulting in no position, check and treatment can be. 3, the return oil pressure is insufficient, the inlet oil is not unloaded, the operation is not smooth.
