(Korea retractable cylinder,produced by Hengyu Group）

retractable cylinder are widely used in Korea，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed retractable cylinder for customers from Korea.

Introduction to retractable cylinder:

retractable cylinder abnormal sound, hysteresis phenomenon cause and elimination method: the piston rod is extended with abnormal sound and hysteresis, if the retractable cylinder is placed for a period of time, the retractable cylinder may enter the air, and the movement can be normal after dozens of repeated movements. If it still cannot be eliminated, check whether the load is aligned with the axis of the piston rod; Retracted piston rod installation helps to align the load with the piston rod. If the flow is unstable, it will also lead to abnormal movement of the piston rod. Check the relevant components of the hydraulic system.

The retractable cylinder should be used correctly and maintained regularly. The retractable cylinder should be deflated before use, the buffer regulating valve should be adjusted to a reasonable position, the cleanliness of the oil should be checked regularly, the dust on the retractable cylinder should be cleaned regularly, and attention should be paid to waterproof and fireproof.

If the piston rod and retractable cylinder are stuck or the retractable cylinder is blocked, at this time, no matter how to operate, the retractable cylinder does not move or has little action. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the retractable cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

When installing the retractable cylinder pipe, the pipe should be cleaned after installation, and should not pass through the retractable cylinder block, and the by-pass pipe must be installed in front of the oil port of the retractable cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the retractable cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the retractable 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.

Answers to some questions about retractable cylinder:

The diameter of the cylinder is 180mm and the pressure is 14mpa. How many tons can the cylinder hold?
Calculate the area of the cylinder, 3.14*9*9=254.34 square centimeters, take the approximate number of engineering, 1 mpa pressure is about 10 kg per square centimeter, 14 mpa pressure is 140 kg per square centimeter, that is 254.34*140=35607.6 kilograms, it can be known that the cylinder can be about 35 tons in theory.

What is the difference between hydraulic cylinder self-adjusting buffer and adjustable buffer?
If it is the buffer device inside the cylinder, then there are 4 basic forms, cylindrical buffer device, conical buffer device, variable throttle and adjustable flow groove. The biggest difference between the first three and the latter is that the latter can be adjusted through the external thimble to change the buffer strength, the first three mainly rely on the buffer device and buffer groove form to achieve the buffer (among them, the first type of buffer strength will not change, and the buffer strength of the two and three forms of buffer devices can be gradually increased).
