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

stacker cylinder are widely used in Romania，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 Romania.

Introduction to stacker cylinder:

In recent years, the processing process of the stacker cylinder generally adopts the rolling method, which is a pressure finishing processing, which uses the cold plastic characteristics of the metal at room temperature, and uses the rolling tool to exert a certain pressure on the surface of the workpiece, so that the surface metal of the workpiece produces plastic flow, and fills in the low concave trough of the original residue, and the roughness value of the workpiece surface is reduced. Due to the plastic deformation of the rolled surface metal, the surface tissue is cold hardened and the grain is fine, forming a dense fiber, and forming a residual stress layer, and the hardness and strength are increased, thus improving the wear resistance, corrosion resistance and compatibility of the workpiece surface. Rolling is a plastic machining method without cutting.

The internal leakage of the stacker cylinder is an important indicator to measure the quality of the stacker cylinder: the internal leakage of the stacker cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the stacker cylinder, so that the stacker cylinder can not accurately and stably stop in a certain position of the stacker cylinder, so it is one of the main indicators of the stacker cylinder.

Because of the slightly complex structure of the buffer stacker cylinder, sometimes there will be problems, such as when the stacker cylinder with the buffer device is started in reverse, the piston often stops temporarily or reverses. Elimination method: The orifice of the check valve is too small, so that the amount of oil entering the buffer chamber is too small, and even a vacuum occurs, so the above fault phenomenon will occur when the buffer plunger leaves the end cover. In this regard, the orifice of the check valve should be increased.

If the stacker cylinder piston rod is found to be worn, it can be brushed and plated first, then ground, and finally adjust the mating accuracy of the piston rod and the guide sleeve. At this time, the guide sleeve can be properly redrilled or the guide sleeve can be re-turned. When making the above repairs, remember to replace various rubber seals in time.

Answers to some questions about stacker cylinder:

Where's the hydraulic cylinder bleed valve?
There is a vent hole at the top of the cylinder next to the intake pipe. Generally, it can be used, and the air in the cylinder can be naturally drained after several moves.

What do cylinder internal leakage and external leakage mean?
Internal leakage means that the piston seal in the cylinder is not strict, there is a leak between the two chambers of the cylinder, the oil is still in the cylinder, and the external leakage is that the oil leaks to the outside of the cylinder.
