tailboard balance cylinder are widely used in Ireland，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed tailboard balance cylinder for customers from Ireland.

Introduction to tailboard balance cylinder:

The daily inspection of the tailboard balance cylinder includes: checking the connection of the tailboard balance cylinder and the pipe joint for leaks. Check the tailboard balance cylinder rod for leaks. Check the tailboard balance cylinder connection for leaks. When the tailboard balance cylinder moves, the work is normal and smooth. Whether the tailboard balance cylinder has internal leakage.

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.

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

What kind of process is used in the tailboard balance cylinder to make high-quality tailboard balance cylinder products: the body is the main component of the tailboard balance 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 tailboard balance 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 tailboard balance 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 tailboard balance cylinder increases by 25%. If the service life of the tailboard balance 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. tailboard balance 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 tailboard balance 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 tailboard balance cylinder are stuck or the tailboard balance cylinder is blocked. At this time, no matter how to manipulate, the tailboard balance 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 tailboard balance cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

Answers to some questions about tailboard balance cylinder:

What are the four cylinders of the truck crane?
The four cylinders of the truck crane generally refer to the telescopic cylinder of the boom (to adjust the length of the boom), the variable amplitude cylinder of the boom (to adjust the elevation Angle of the boom), the horizontal telescopic cylinder of the support leg and the vertical cylinder of the support leg.

How to exhaust hydraulic cylinder?
Exhaust: The hydraulic system generally does not have exhaust, the use of the tank can exhaust, the oil operation will bring the gas back to the tank, and the tank can be communicated with the atmosphere. The gas will escape from the oil.
