(Slovakia stroke adjustable cylinder,produced by Hengyu Hydraulic Co., Ltd）

stroke adjustable cylinder are widely used in Slovakia，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed stroke adjustable cylinder for customers from Slovakia.

Introduction to stroke adjustable cylinder:

In the process of using the stroke adjustable cylinder, sometimes such a problem will occur, the stroke adjustable cylinder can not act immediately after the instruction of the stroke adjustable cylinder action is issued, and it must be moved after a short time, or sometimes it can move and stop moving, showing that the operation is very irregular. The cause and elimination of this failure mainly include air in the oil stroke adjustable cylinder. Elimination method: exhaust through the exhaust valve. Check the piston rod reciprocating parts of the sealing ring for air inhalation, if so, replace the sealing ring.

Causes and countermeasures of oil stroke adjustable cylinder leakage: Cast iron ring seal allows a certain degree of internal leakage. The impurities in the stroke adjustable cylinder will lead to premature wear of the piston seal, replace the piston seal; If the stroke adjustable cylinder is visibly scarred, the stroke adjustable cylinder must be replaced. It can be pressurized at one end of the stroke adjustable cylinder and opened at the other end of the oil port to observe whether there is obvious internal leakage at the end of the oil port. Most stroke adjustable cylinder piston drift may not come from the stroke adjustable cylinder, the above method to determine the stroke adjustable cylinder without internal leakage is helpful to determine the problem of the hydraulic system related components.

The role of the stroke adjustable cylinder in the mold industry: the stroke adjustable 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 stroke adjustable 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 stroke adjustable 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.

stroke adjustable cylinder and hydraulic station selection: Select the type and structure of the stroke adjustable cylinder according to the operation requirements of the main engine. According to the external load force borne by the stroke adjustable cylinder, such as gravity, friction force of the external mechanism, inertia force and working load, determine the load change law of the stroke adjustable cylinder in each stage of the stroke and the power value that must be provided. Determine the diameter of the piston and piston rod according to the working load of the stroke adjustable cylinder and the selected oil working pressure. the flow rate of the hydraulic pump is determined according to the movement speed of the stroke adjustable cylinder, the diameter of the piston and the piston rod.

Answers to some questions about stroke adjustable cylinder:

Why can't the hydraulic cylinder be pulled back after pushing to the limit?
May be long-term use to the limit position, resulting in serious wear caused! The solution is to add the stroke switch or disassemble and add gaskets before and after the piston.

How to determine the rated working pressure of the hydraulic cylinder?
Under normal circumstances, the working pressure is determined according to the size of the load and the installation space (the allowable diameter of the cylinder). In some special occasions, the smaller the cylinder, the better, the pressure level must be increased. The cylinder pressure is related to the estimated cost. The higher the pressure, the thicker the wall, the higher the cost, but conversely, the lower the pressure, the larger the diameter of the cylinder (when the same thrust) is required, the same high cost. Therefore, the rated pressure of the cylinder is concentrated in about 35 mpa, taking into account the cylinder diameter and wall thickness.
