Republic of Lithuania hydraulic cylinder,roller press hydraulic cylinder manufacturer,roller press hydraulic cylinder
(Republic of Lithuania roller press hydraulic cylinder,produced by Hengyu Group）
roller press hydraulic cylinder are widely used in Republic of Lithuania，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed roller press hydraulic cylinder for customers from Republic of Lithuania.
When the roller press hydraulic cylinder is in use, once the seal and guide support ring are found to be defective, the seal with the same structural form and appropriate material should be replaced according to the structural form of the roller press hydraulic cylinder seal to be repaired, so as to minimize the thickness of the oil film between the seal and the sealing surface and reduce the leakage of the seal.
The role of the roller press hydraulic cylinder in the mold industry: the roller press hydraulic cylinder has a variety of uses in the mold, one is that the core distance is very large, or because of the mechanism of the product, only the roller press hydraulic cylinder is reasonable or more cost saving. Let the side core be extracted before opening the mold. Hot runner is mainly based on the product to decide, sometimes customers require the use of hot runner, the price is more expensive, but there are many benefits, you can save raw materials, shorten the molding cycle The roller press hydraulic cylinder has an irreplaceable role in the heavy industry production process: it is mainly used in places that need to support heavy objects for a long time, and it can still support heavy objects when the oil pressure is removed, and it is safe and reliable. Can be used underwater, single action, load reversion, nut self-locking to make the load safer, especially in large projects, is easy to operate control and self-locking jack, designed with a safety pressure retaining device, built-in pressure relief valve to prevent overload, to protect the self-locking jack to facilitate safe operation. The connection of the device is connected by high pressure hose and threaded joint, which has the advantages of fast use and overcoming the shortcomings of fast traditional joint oil leakage. It is mainly used for equipment installation and toppling operation in various industries such as electric power, construction, machinery manufacturing, mining, railway bridge, shipbuilding and so on.
When installing the roller press hydraulic cylinder pipe, the pipe should be cleaned after installation, and should not pass through the roller press hydraulic cylinder block, and the by-pass pipe must be installed in front of the oil port of the roller press hydraulic cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the roller press hydraulic cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the roller press hydraulic cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.
If the roller press hydraulic cylinder is sliding or crawling (stop and go), check whether there is any astringency inside the roller press hydraulic cylinder. The internal parts of the roller press 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 roller press 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 roller press 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 roller press hydraulic cylinder bore processing is out of whack. Because the piston and roller press hydraulic cylinder, guide rail and piston rod are relative If the roller press 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 roller press hydraulic cylinder weight composition and calculation. The weight of the roller press hydraulic cylinder is composed of the roller press hydraulic cylinder diameter, the outer diameter and weight of the roller press 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.
Injection molding machine die thimble on the side of the feed nozzle, the oil cylinder pull the thimble shift, how to debug the oil cylinder?
The cylinder is connected with the neutron of the injection molding machine, the neutron is retreated after the opening mold is in place, the cylinder taps the thimble plate to the top, and then takes, and the neutron is reset.
What brand of hydraulic cylinder seal ring is best?
Depending on the specific product, the world famous seal brands are NOK, CFW, PARKER, TSS, WKF, DINGZING DZ, ASTON, HALLITE, TECNOLAN and so on.
