(Thailand stacker cylinder,produced by Hengyu Hydraulic Cylinder Factory）

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

Introduction to stacker cylinder:

The repair method of stacker cylinder wear: 1. Metal repair material is applied to the scratched surface; The first layer should be thin, uniform and fully covered with the scratched surface to ensure the best adhesion between the material and the metal surface, and then apply the material to the entire repair site and press repeatedly to ensure that the material is filled and reaches the required thickness, so that it is slightly higher than the surface of the guide rail; 2, the material at 24℃ to fully achieve the performance of 24 hours, in order to save time, can be through the tungsten halogen lamp to increase the temperature, the temperature rises 11℃, the curing time will be reduced by half, the best curing temperature 70℃; 3. After the material is cured, use a fine grinding stone or a scraper to repair and smooth the material higher than the surface of the guide rail, and the construction is completed.

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.

When the stacker cylinder is installed, the piston and the stacker cylinder head and other parts have large mass, large size and large inertia, even if there is a lifting equipment auxiliary installation, because the specified clearance is small, no matter how hard it will be put into, therefore, the end of the piston or the stacker cylinder head boss is easy to cause scars when it hits the inner surface of the stacker cylinder wall. The solution to this problem: for a large number of small products, the use of autocratic assembly oriented tools during installation; For heavy, thick and large large and medium-sized stacker cylinders, only careful and careful operation can be avoided.

stacker cylinders in series, parallel and series parallel. Series: In the stacker cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Series: In the stacker cylinder, the oil inlet of the subsequent reversing valve is the supply of the previous oil return, and there is no separate oil return circuit connected with the oil return in each valve. Parallel: the pressure oil in the stacker cylinder is connected with the inlet oil of each reversing valve, and the return oil is collected by the return oil circuit. Series parallel: For this one, compared with the simple series and parallel, it is slightly more complicated, but it is not impossible to understand. The series refers to the oil in the stacker cylinder, which is in series form, but can not form a series circuit, and the parallel refers to the oil return circuit of each valve, which is in parallel.

Answers to some questions about stacker cylinder:

Why can't the hydraulic cylinder be pulled back after pushing to the limit?
May be long-term use to the limit position, resulting in serious wear caused! The solution is to add the stroke switch or disassemble and add gaskets before and after the piston.

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.
