Ireland hydraulic cylinder,synchronous hydraulic cylinder manufacturer,synchronous hydraulic cylinder(Ireland synchronous hydraulic cylinder,produced by Hengyu Hydraulic Co., Ltd)
synchronous hydraulic cylinder are widely used in Ireland,because of excellent fatigue and impact resistance,no need for deceleration device,long service life.So our company has designed synchronous hydraulic cylinder for customers from Ireland.
If the synchronous hydraulic cylinder is sliding or crawling (stop and go), check whether there is any astringency inside the synchronous hydraulic cylinder. The internal parts of the synchronous hydraulic 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 synchronous hydraulic 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 synchronous hydraulic 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 synchronous hydraulic cylinder bore processing is out of whack. Because the piston and synchronous hydraulic cylinder, guide rail and piston rod are relative If the synchronous hydraulic 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 synchronous hydraulic cylinder weight composition and calculation. The weight of the synchronous hydraulic cylinder is composed of the synchronous hydraulic cylinder diameter, the outer diameter and weight of the synchronous hydraulic 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.
If the synchronous hydraulic cylinder slips or crawls, please check whether there is astringency inside the synchronous hydraulic cylinder, because the internal parts of the synchronous hydraulic cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, the action resistance is too large, so that the piston speed of the synchronous hydraulic cylinder changes with the different stroke position, and the slip or crawl occurs. 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 synchronous hydraulic 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.
The repair method of synchronous hydraulic cylinder wear: 1. Metal repair material is applied to the scratched surface; The first layer should be thin, uniform and fully covered with the scratched surface to ensure the best adhesion between the material and the metal surface, and then apply the material to the entire repair site and press repeatedly to ensure that the material is filled and reaches the required thickness, so that it is slightly higher than the surface of the guide rail; 2, the material at 24℃ to fully achieve the performance of 24 hours, in order to save time, can be through the tungsten halogen lamp to increase the temperature, the temperature rises 11℃, the curing time will be reduced by half, the best curing temperature 70℃; 3. After the material is cured, use a fine grinding stone or a scraper to repair and smooth the material higher than the surface of the guide rail, and the construction is completed.
When the synchronous hydraulic cylinder is repaired, its inner and outer diameter and roundness should be accurately measured. If the inner hole of the synchronous hydraulic cylinder is badly worn, it can be repaired by grinding the mandrel or honing on the boring machine. If the piston is worn, it can be repaired by electroplating, and serious wear should be replaced.
What is the difference between gas-hydraulic pressurized cylinder, pneumatic cylinder and oil cylinder?
The cylinder block is small and the force is large, constant speed and variable speed can be used (easy to change), the adjustment of the output is also convenient, and the freedom of transmission is high. However, maintenance costs and installation costs are high, and there is the trouble of mild oil pollution. Easy cylinder control, low price, easy access to energy. But the force is small, and can not achieve the effect of stable speed. The gas-liquid pressurized cylinder has the advantages of both of the above: environmental protection and energy saving, easy control, and simple adjustment. However, the output of the trip has certain restrictions, more suitable for short trips, large output, but also environmental protection and energy saving and low configuration of the occasion.
How many tons can a 10mpa cylinder with a diameter of 100 hold up?
About 8 tons. Algorithm: Cylinder cross-sectional area = π* (100/2) ^2=3.14*2500=7850 square mm = 0.00785 square meters pressure = pressure * Cross-sectional area = 10000000Pa*0.00785 square meters = 78500 n mass = pressure /g = 78500 N ÷9.8 n/kg = 8010 kg = 8.01 Tons.
