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

stacker cylinder are widely used in Australia，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 Australia.

Introduction to stacker cylinder:

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.

The viscosity of the working oil used in the stacker cylinder is 29~74mm2/S, and ISO VG46 anti-wear hydraulic oil is recommended. Working oil temperature within the range of -20~80. C. When the ambient temperature and service temperature are low, the oil with lower viscosity can be selected.

If the stacker cylinder is sliding or crawling (stop and go), check whether there is any astringency inside the stacker cylinder. The internal parts of the stacker cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, and the action resistance is too large, so that the piston speed of the stacker cylinder changes with the different stroke position, and there is slip or crawl. Most of the reasons are due to poor assembly quality of parts, surface scars or sintered iron filings, so that the resistance increases, the speed decreases. For example, the piston is different from the piston rod or the piston rod is bent, the stacker cylinder or the piston rod is offset from the mounting position of the guide rail, and the sealing ring is too tight or too loose. The solution is to repair or adjust, replace damaged parts and remove iron filings. At the same time, check whether the lubrication is good or whether the stacker cylinder bore processing is out of whack. Because the piston and stacker cylinder, guide rail and piston rod are relative If the stacker cylinder is crawling seriously, check whether air has entered the hydraulic system. Air compression or expansion can cause the piston to slip or crawl. The exclusion measures are to check the hydraulic pump, set up a special exhaust device, and quickly operate the exhaust several times in the full stroke. Check the seals at the same time, because the quality of the seals is directly related to slippage or crawling. When the O-ring is used under low pressure, compared with the U-ring, it is easy to slip or crawl because of the higher surface pressure and the larger difference between static and static friction resistance. The surface pressure of the U-shaped sealing ring increases with the increase of pressure, although the sealing effect is correspondingly improved, but the difference between static and static friction resistance is also larger, the internal pressure increases, affecting the rubber elasticity, due to the increase in the contact resistance of the lip, the sealing ring will tip over and the lip elongation, and it is also easy to cause slip or crawling stacker cylinder weight composition and calculation. The weight of the stacker cylinder is composed of the stacker cylinder diameter, the outer diameter and weight of the stacker cylinder, the rod diameter, and the weight of the accessories, so in calculation, it is to add all these together to get the specific value. However, if there are special circumstances, it may be calculated separately. This work can be carried out by yourself, but it can also be carried out by professionals, so that mistakes can be avoided.

In the hydraulic system, sometimes the inner layer of the rubber hose is peeled off, so that the oil circuit is on and off, resulting in irregular stacker cylinder action. Troubleshooting method: Replace the rubber hose.

Answers to some questions about stacker cylinder:

How to make 4 cylinders balance lifting weight at the same time?
The cost of the synchronous valve is lower, 4 cylinders need 3 synchronous valves, to be precise you can use a synchronous motor, but it is more expensive. There is another way, that is to install a throttle valve in each cylinder, respectively adjust the speed of the cylinder.

What are the functions of hydraulic cylinders?
Hydraulic cylinder is a hydraulic actuator, the specific role depends on the installation occasion and the type of hydraulic cylinder. Hydraulic cylinder is mainly used in machinery, and it is the most important component of construction machinery. It is important core component which mainly provide power for machinery.
