(Germany stacker cylinder,produced by Hebei Hengyu company）

stacker cylinder are widely used in Germany，because of excellent temperature resistance，no transmission clearance，powerful torque.So our company has designed stacker cylinder for customers from Germany.

Introduction to stacker cylinder:

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.

When the stacker cylinder is in use, once the seal and guide support ring are found to be defective, the seal with the same structural form and appropriate material should be replaced according to the structural form of the stacker cylinder seal to be repaired, so as to minimize the thickness of the oil film between the seal and the sealing surface and reduce the leakage of the seal.

When the stacker cylinder needs to be stored for a period of time, please follow the recommended methods: The stacker cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the stacker cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil stacker cylinder should not be in direct contact with water vapor for a long time. The stacker cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the stacker cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the stacker cylinder Before working, the stacker cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the stacker cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

The difference between the plunger stacker cylinder and the piston stacker cylinder is that the piston in the stacker cylinder is replaced by a shaft plunger, which is used in hydraulic transmission requiring a long mechanical stroke, and can only input pressure oil from one direction, pressurize in a single direction, and form a thrust to push the plunger to move. The return trip of the plunger depends on the plunger itself to fall, and some rely on the spring to push back to the original position. Usually used plunger type stacker cylinder, its inner hole does not need mechanical finishing, as long as the plunger round grinding can be assembled.

Answers to some questions about stacker cylinder:

How to disassemble injection molding machine injection cylinder?
If it is not repaired for a long time, it is recommended to open both ends, comprehensively check the oil seal and piston ring inside, this is not much difficulty, pay attention to not install reverse when changing the oil seal, some piston rings are steel rings are rubber rings, and several interfaces of steel rings are not in the same position; Rubber ring pay attention not to install reverse; Be careful not to damage the oil seal when installing, otherwise it will soon leak oil.

Hydraulic cylinder load algorithm?
If it is thrust, load = working pressure x piston area. If it is pulling force, load = working pressure x(piston area - piston rod area).
