Japan retractable cylinder

(Japan retractable cylinder,produced by Hengyu Hydraulic Cylinder Factory)

retractable cylinder are widely used in Japan,because of excellent temperature resistance,clever hydraulic energy conversion,simple structure and reliable operation.So our company has designed retractable cylinder for customers from Japan.

Introduction to retractable cylinder:

After the retractable cylinder is installed, lubricating grease should be added to the relative moving parts such as earring and middle hinge shaft before trial operation.

If the retractable cylinder slips or crawls, please check whether there is astringency inside the retractable cylinder, because the internal parts of the retractable 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 retractable 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 retractable 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.

Protection of the retractable cylinder surface: During the dismantling process, safety protection should be carried out on the retractable cylinder to prevent objects from falling and welding slag from falling to the surface, causing damage to the retractable cylinder surface. In the process of propulsion, the damaged pipe segments should be prevented from falling and smashing, and the slurry remaining on the surface of the retractable cylinder should be cleaned up in time.

Do not regularly check the damage of the chrome layer of the retractable cylinder: completely extend the retractable cylinder and carefully check whether there is any surface damage such as injury, strain, welding slag, such as the surface damage position, in the retractable cylinder block < 20cm, and the damage depth < 5mm, should be repaired in time to prevent long-term damage to the retractable cylinder seal. Welding slag is strictly prohibited on the surface of the retractable cylinder.

Answers to some questions about retractable cylinder:

What components can control cylinder rising and falling speed and the speed is adjustable?
A throttle or special solenoid valve is required. The reversing valve can choose the three-position reversing valve with P-type middle function. When rising, the reversing valve can be changed to the middle position to achieve differential connection and the fastest speed. Add a combination valve one-way throttle valve in the oil return circuit, connection mode: when the cylinder rises, the oil flows back to the tank through the check valve, the throttle valve is reversed off, when the cylinder falls, the reversing valve is changed to the left or right position (see the structure of the valve), the check valve is reversed off, the oil returns to the tank through the throttle valve, and the speed can be adjusted through the throttle valve.

Is a hydraulic cylinder and a jack the same thing?
Strictly speaking, no. Although the hydraulic principle is used, and even some of the longer jacks are similar to the cylinder, the internal structure of the two is different. There is a check valve inside the jack. After the top lift, the check valve locks the hydraulic oil circuit, and the hydraulic oil only enters and does not exit after the check valve locks, and can be lowered to complete a reciprocating movement. The cylinder is usually connected to the distribution tube to control the movement, and works with a wide variety of distribution valves and distribution systems according to different needs. The jack only needs a simple check valve.
