(Austria stroke adjustable cylinder,produced by Hengyu Group）

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

Introduction to stroke adjustable cylinder:

The "O" ring can be used as an auxiliary seal inside the stroke adjustable cylinder, and the elastic force of the "O" ring makes the sealing slip ring close to the sealing surface, generating sealing pressure to achieve sealing. When the internal hydraulic pressure increases, the "O" ring will further deform and squeeze the slip ring, thereby increasing the sealing pressure and improving the sealing performance. The structure has the characteristics of low friction coefficient, good wear resistance, automatic compensation for wear and absorption of hard particles in the stroke adjustable cylinder, and can be completely sealed.

What kind of process is used in the stroke adjustable cylinder to make high-quality stroke adjustable cylinder products: the body is the main component of the stroke adjustable cylinder, mining single pillar, hydraulic support, gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. Body processing requirements are high, the internal surface roughness requirements are Ra0.4 ~ 0.8&um, the coaxiality, wear resistance requirements are strict. The basic feature of body is deep hole processing, which has always troubled the processing personnel. The stroke adjustable cylinder products of our company mainly use rolling processing, because the surface layer has surface residual compressive stress, which helps to close the surface micro-cracks and hinder the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the body can be improved. The correct rolling process of the stroke adjustable cylinder block: broaching block - fine boring block - grinding block. The rolling method is: broaching block - fine boring block - rolling block, the process is 3 parts, but the time is compared: grinding 1 meter of the block is about 1-2 days, rolling 1 meter of the block is about 10-30 minutes. Input comparison: grinding machine or quilting machine (tens of thousands - millions), rolling knife (ten thousand - tens of thousands). After rolling, the surface roughness of the hole decreases from RA3.2-6.3um before rolling to RA0.4-0.8&um, the surface hardness of the hole increases by about 30%, and the fatigue strength of the inner surface of the stroke adjustable cylinder increases by 25%. If the service life of the stroke adjustable cylinder is only considered, it is increased by 2 to 3 times, and the efficiency of the boring and rolling process is about 3 times higher than that of the grinding process. stroke adjustable cylinder misoperation or operation failure may be caused by the following reasons, you can start from these aspects of the investigation: (1) spool stuck or valve hole blocked. When the spool of the flow valve or direction valve is stuck or the valve hole is blocked, the stroke adjustable cylinder is prone to misoperation or operation failure. At this time, the contamination of the oil should be checked; Check whether dirt or colloidal deposits are stuck in the spool or blocking the valve hole; Check the wear of the valve body, clean and replace the system filter, clean the fuel tank, and replace the hydraulic medium. (2) The piston rod and stroke adjustable cylinder are stuck or the stroke adjustable cylinder is blocked. At this time, no matter how to manipulate, the stroke adjustable cylinder does not move or moves very little. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the stroke adjustable cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

When the stroke adjustable cylinder is disassembled due to oil leakage and other faults, the position of the piston should be moved to any end position of the stroke adjustable cylinder by applying liquid pressure. Improper tapping and sudden drop should be avoided during disassembly.

Factors that should be considered when selecting the oil seal in the stroke adjustable cylinder: some specific factors should be taken into account when selecting the oil seal in the stroke adjustable 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: stroke adjustable cylinder diameter, piston rod diameter, piston rod and piston groove size, stroke adjustable cylinder working pressure, stroke adjustable cylinder movement speed, hydraulic system oil temperature and stroke adjustable cylinder working environment.

Answers to some questions about stroke adjustable cylinder:

How to refuel pneumatic riveting cylinder?
First put the gun flat, that is, horizontally, while pushing the stroke positioning pin and loosen the back cover, rotate to the left for a maximum of five turns, and then use a wrench to loosen the oil sealing screw, slowly add the hydraulic oil and let the air out, fill up to tighten the oil sealing screw. This process of adding hydraulic oil is over.

Is there a way to make the cylinder stop pushing when it hits something hard during the process of pushing?
The simplest solution is to press the stop switch, this switch has a mechanical type, touch the object on the action or send a stop signal, through the operation of the motor control cylinder; There is also an induction switch, that is, when the hydraulic cylinder expands to the range of the induction switch can sense the signal, it sends a signal to let the motor act, resulting in the corresponding action of the cylinder.
