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

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

Introduction to stroke adjustable cylinder:

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

Because of the slightly complex structure of the buffer stroke adjustable cylinder, sometimes there will be problems, such as when the stroke adjustable cylinder with the buffer device is started in reverse, the piston often stops temporarily or reverses. Elimination method: The orifice of the check valve is too small, so that the amount of oil entering the buffer chamber is too small, and even a vacuum occurs, so the above fault phenomenon will occur when the buffer plunger leaves the end cover. In this regard, the orifice of the check valve should be increased.

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

When the control pressure of the hydraulic system is too low, the stroke adjustable cylinder will appear wrong or no action, because the throttle resistance in the control pipeline may be too large, the flow valve is improperly adjusted, the control pressure is inappropriate, and the pressure source is interfered with. At this time, check the control pressure source to ensure that the pressure is adjusted to the specified value of the system.

Answers to some questions about stroke adjustable cylinder:

How to remove the cylinder correctly?
(1) Before disassembling the hydraulic cylinder, the hydraulic circuit should be depressurized. Otherwise, when the tubing joint connected with the cylinder is loosened, the high-pressure oil in the circuit will be quickly ejected. The hydraulic circuit of the hydraulic press should first loosen the hand wheel or pressure regulator screw at the relief valve, so that the pressure oil is unloaded, and then block the power supply or block the power source to stop the operation of the hydraulic equipment. (2) When disassembling, it should prevent damage to the top thread of the piston rod, the oil thread, the appearance of the piston rod, the inner wall of the cylinder liner, etc. In order to prevent the piston rod and other slender parts from twisting or deformation, the use of cushion wood support balance when placed. (3) Disassemble in order.

Why does the hydraulic cylinder not return?
For a spring return cylinder, it is possible that 1, the spring is damaged. You can check it for processing. 2, the oil in the oil path is not unloaded, causing it to be unable to reset. 3, the cylinder piston is dead, resulting in no position. For double-acting cylinders, it is possible to: 1, the spool is not reversed, or is not changed to the correct position, check whether the reversing valve is normal (and whether there is electricity). 2, the cylinder piston is dead, resulting in no position, check and treatment can be. 3, the return oil pressure is insufficient, the inlet oil is not unloaded, the operation is not smooth.
