tailboard balance cylinder are widely used in Norway，because of long service life，smooth movement，high work efficiency.So our company has designed tailboard balance cylinder for customers from Norway.

Introduction to tailboard balance cylinder:

The tailboard balance cylinder body is commonly made of No. 20, 35, 45 seamless steel pipe, and the steel pipe is honed or rolled to achieve the roughness requirement within 0.4μm. The low pressure tailboard balance cylinder can use 20 steel pipe, and the high pressure tailboard balance cylinder can use 45 steel pipe.

The difference between the integral tailboard balance cylinder and the split tailboard balance cylinder: The integral tailboard balance cylinder and the split tailboard balance cylinder in the tailboard balance cylinder are two different tailboard balance cylinders, and they are very different. The whole tailboard balance cylinder, which is cast in one body, is not prone to problems such as oil leakage; The split tailboard balance cylinder is welded twice, so if it is not handled well at the welding, it is prone to problems such as oil leakage and tailboard balance cylinder damage. Therefore, it is obvious that the answer to this question is for difference.

If the piston rod and tailboard balance cylinder are stuck or the tailboard balance cylinder is blocked, at this time, no matter how to operate, the tailboard balance cylinder does not move or has little action. 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 tailboard balance cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

If the tailboard balance cylinder is sliding or crawling (stop and go), check whether there is any astringency inside the tailboard balance cylinder. The internal parts of the tailboard balance 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 tailboard balance 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 tailboard balance 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 tailboard balance cylinder bore processing is out of whack. Because the piston and tailboard balance cylinder, guide rail and piston rod are relative If the tailboard balance 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 tailboard balance cylinder weight composition and calculation. The weight of the tailboard balance cylinder is composed of the tailboard balance cylinder diameter, the outer diameter and weight of the tailboard balance 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.

Answers to some questions about tailboard balance cylinder:

What valve is used to control the speed of the cylinder?
Hydraulic cylinder for lifting is generally the piston rod downward installation, to achieve the fast and slow speed of the cylinder, you can add a two-digit three-way electromagnetic reversing valve + a throttle valve on a branch at the bottom of the cylinder, you can achieve speed change, control mode can be controlled by time control can also be controlled by stroke switch. If you want to achieve more accurate control can use proportional valve control.

What are the requirements for hydraulic cylinder assembly? ① The installation of the cylinder should be solid and reliable. In order to prevent the influence of thermal expansion, in the case of large stroke and hot working conditions, one end of the cylinder must be kept floating.② pipe connection shall not be relaxed.③ The mounting surface of the hydraulic cylinder and the sliding surface of the piston rod should maintain sufficient parallelism and perpendicality.④ The central axis of the moving cylinder should be concentric with the center line of the load force, otherwise it will cause lateral force, which is easy to wear the seal And piston damage. The greater the distance between the supporting points of the piston rod, the smaller its wear. For the hydraulic cylinder of the moving object, the installation should keep the cylinder parallel with the moving object, and the degree of non-parallelism is generally not greater than 0.05mm/m. ⑤The sealing ring should not be installed too tightly, especially the U-shaped sealing ring.
