(Bulgaria stacker cylinder,produced by Hengyu Group）

stacker cylinder are widely used in Bulgaria，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed stacker cylinder for customers from Bulgaria.

Introduction to stacker cylinder:

The piston rod of the stacker cylinder has two kinds of solid rod and hollow rod, and one end of the hollow piston rod needs to be set aside for welding and heat treatment. The solid piston rod material is 35, 45 steel, and the hollow piston rod material is 35, 45 seamless steel pipe. After rough machining, the piston rod is conditioned to 229~285HB in India, and if necessary, the hardness is 45~55HRC after high-frequency quenching.

The body of the stacker cylinder on the processing process requirements: the body of the stacker cylinder is an important and essential part of the stacker cylinder, because it has an irreplaceable role. The processing requirements for this part are very high, requiring that the surface roughness of the stacker cylinder after processing should reach 0.4-0.8um, and the coaxiality and wear resistance requirements are also very high.

The commonly used buffer structure of the stacker cylinder is composed of a piston boss and a stacker cylinder head groove. When the piston moves close to the stacker cylinder head, it gradually enters the groove, and the oil in the groove is extruded through the gap between the boss and the groove, which increases the oil return resistance, produces the braking effect and realizes the buffer. Generally, a buffer mechanism should be used when the pressure is above 10MP.

Factors that should be considered when selecting the oil seal in the stacker cylinder: some specific factors should be taken into account when selecting the oil seal in the stacker cylinder, so as to have correct consideration and get accurate results, and then avoid wrong selection. The factors and aspects that should be taken into account are eight: stacker cylinder diameter, piston rod diameter, piston rod and piston groove size, stacker cylinder working pressure, stacker cylinder movement speed, hydraulic system oil temperature and stacker cylinder working environment.

Answers to some questions about stacker cylinder:

What does cylinder speed ratio mean?
The speed ratio of the cylinder is the ratio of the reciprocating speed of the piston, equal to the ratio of the rodless cavity area to the roded cavity area.

How to take out the diaphragm of hydraulic cylinder? The septum ring is also known as the septum sleeve, when the cylinder is too long, and does not need too much travel, add the septum sleeve, limit the stroke of the hydraulic cylinder, set on the piston rod, only contact with the guide sleeve and piston, do not cooperate with the cylinder, limit the stroke, take out the difficulty is different, need to have such a professional tool, before taking out to consult the manufacturer.
