Slovakia stacker cylinder

(Slovakia stacker cylinder,produced by Hebei Hengyu company)

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

Introduction to stacker cylinder:

When the stacker cylinder is installed, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the stacker cylinder head, earring (or middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent rigid interference and cause unnecessary damage.

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

stacker cylinder hydraulic oil selection: The recommended working oil viscosity of the stacker cylinder is 10 ~ 110cSt (1.8 ~ 15E), ISO VG46 hydraulic oil. The normal working oil temperature is 10 ~ 70℃, and the ambient temperature is in the range of -20 ~ 80℃. When the ambient temperature and service temperature are low, the hydraulic oil with lower viscosity can be selected.

If the stacker cylinder operation failure, you can start from these aspects to troubleshoot: (1) the hydraulic system control pressure is too low. The throttling resistance in the control line may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is disturbed. At this time, the control pressure source should be checked to ensure that the pressure is adjusted to the specified value of the system; (2) Air enters the hydraulic system. Mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced. (3) The initial action of the stacker cylinder is slow. In the case of low temperature, the hydraulic oil viscosity is large, poor flow, resulting in slow stacker cylinder action. The improvement method is to replace the hydraulic oil with better viscosity and temperature performance If the stacker cylinder is weak and cannot push the load, please check the internal leakage problem. The internal leakage of the stacker cylinder includes the leakage caused by excessive wear of the stacker cylinder block seal, the piston rod and the seal cover seal and the 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. The main cause of excessive piston seal wear is improper adjustment of the speed control valve, resulting in excessive back pressure and improper seal installation or hydraulic oil contamination. The second is that foreign bodies enter the assembly and the quality of sealing materials is not good. The result is that the action is slow and weak, and in serious cases, it will cause damage to the piston and stacker cylinder, and the phenomenon of "pulling the stacker cylinder" appears. The treatment method is to adjust the speed control valve, and the necessary operations should be done according to the installation instructions.

Answers to some questions about stacker cylinder:

Design a hydraulic cylinder, the inner diameter of the cylinder is 100mm, what size of piston rod is best used?
This involves how much speed ratio you need, that is, the area ratio of the rod cavity and the rodless cavity, if the weight is relatively large, it is recommended that the speed ratio choose 2, that is, the piston rod diameter choose 70mm, under normal circumstances, the speed ratio choose 1.46, the piston rod diameter choose 55mm. Of course, there are many factors that affect the diameter of the piston rod, such as stroke, stroke is too long, in order to stabilize the work of the hydraulic cylinder, its diameter also needs to choose a relatively large, sometimes even non-standard products, need to choose according to the actual situation.

What is the difference between single acting hydraulic cylinder and double acting hydraulic cylinder?
Single action hydraulic cylinder is a single direction force work, the return of the plunger depends on itself or the weight of the mechanism to return. The double acting hydraulic cylinder is mainly different from the extension and retraction of the piston (the thrust and tension of the saying), which are all operated by the action of liquid pressure.
