Qatar hydraulic cylinder,synchronous hydraulic cylinder manufacturer,synchronous hydraulic cylinder(Qatar synchronous hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory)
synchronous hydraulic cylinder are widely used in Qatar,because of no need for deceleration device,long service life,no transmission clearance.So our company has designed synchronous hydraulic cylinder for customers from Qatar.
The role of the synchronous hydraulic cylinder in the mold industry: the synchronous 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 synchronous 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 synchronous 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.
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.
When the long-stroke synchronous hydraulic cylinder rotates horizontally, the piston rod bends due to its own weight, causing the guide sleeve and piston to produce biased load, resulting in synchronous hydraulic cylinder head seal damage, oil leakage, and piston sleep in the synchronous hydraulic cylinder. The following measures can be taken: increase the piston plan to adjust the piston outer circle and process it into a convex drum, so that the piston can self-position, improve the force situation, and reduce and avoid pulling the synchronous hydraulic cylinder; The piston and the piston rod are connected with a spherical joint.
When the piston speed of the synchronous hydraulic cylinder is high, the steel ball of the check valve flows with the oil flow, so that the valve hole is blocked, and the synchronous hydraulic cylinder moves irregularly. Elimination method: Replace the steel ball with a cone valve or spool with a guide shoulder.
Hydraulic cylinder cost calculation method
1, Price cost accounting. Hydraulic cylinder price is composed of cost, profit and tax rate. Among them, the cost includes material cost, processing cost, assembly test fee, factory management fee (including the cost of designing drawings, etc., and the salary of management personnel is shared equally), brand promotion fee, utility and electricity equipment depreciation fee and other expenses. Cost of materials, including cylinder composition cylinder, piston rod, front and rear cover, guide, piston, seal, other accessories, etc. 2, Roughly estimate cylinder price = cylinder weight * parameters, parameters comprehensive consideration of various material costs and processing fees. The general market parameter is 20, the smaller and lighter the cylinder, the larger and heavier the cylinder, the smaller the parameter.
Why the cylinder cannot operate normally after the explosion-proof valve is installed?
The pipeline explosion-proof valve is specially designed to prevent pipeline damage and free fall of the cylinder, so there must be back pressure to open. If there is no oil return pressure, or the oil return pressure is too small, and can not adjust the oil return pressure, such a system with explosion-proof valves is more troublesome, it is recommended to add a one-way throttle valve between the cylinder and the tank to establish back pressure. If you understand the explosion-proof valve, you can also try to adjust the opening of the valve (that is, the flow of the regulating valve), and adjust the opening to help the valve to open.
