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

retractable cylinder are widely used in Colombia，because of high work efficiency，excellent fatigue and impact resistance，no need for deceleration device.So our company has designed retractable cylinder for customers from Colombia.

Introduction to retractable cylinder:

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.

Most of the failure of the retractable cylinder is because there is a foreign body in the retractable cylinder into the failure of the retractable cylinder, the most problematic is that it is difficult to determine when the foreign body is into the retractable cylinder. After a foreign body enters, if the outer side of the sliding surface of the piston is equipped with a seal with a lip edge, then the lip edge of the seal can scrape the foreign body when working, which is beneficial to avoid scratching. However, the piston equipped with 0-shaped sealing ring has a sliding surface at both ends, and foreign bodies are sandwiched between this sliding surface, which is easy to form scars.

retractable cylinder installation precautions: Before installing the retractable cylinder into the system, the parameters on the retractable cylinder label should be compared with the parameters when ordering. The base of the retractable cylinder must have sufficient stiffness, otherwise the retractable cylinder will bend upward into a bow when pressurized, so that the piston rod will bend.

The body of the retractable cylinder on the processing process requirements: the body of the retractable cylinder is an important and essential part of the retractable cylinder, because it has an irreplaceable role. The processing requirements for this part are very high, requiring that the surface roughness of the retractable cylinder after processing should reach 0.4-0.8um, and the coaxiality and wear resistance requirements are also very high.

Answers to some questions about retractable cylinder:

What is the difference between gas-hydraulic pressurized cylinder, pneumatic cylinder and oil cylinder?
The cylinder block is small and the force is large, constant speed and variable speed can be used (easy to change), the adjustment of the output is also convenient, and the freedom of transmission is high. However, maintenance costs and installation costs are high, and there is the trouble of mild oil pollution. Easy cylinder control, low price, easy access to energy. But the force is small, and can not achieve the effect of stable speed. The gas-liquid pressurized cylinder has the advantages of both of the above: environmental protection and energy saving, easy control, and simple adjustment. However, the output of the trip has certain restrictions, more suitable for short trips, large output, but also environmental protection and energy saving and low configuration of the occasion.

Two cylinders have a reversing control, if the load of the two cylinders is not the same, how to ensure their synchronization?
The piston rod of the cylinder is required to extend synchronization: install A shunt collector valve or synchronous motor at port A of the direction control valve, and then connect the two outlets of the shunt collector valve to the rod-free cavity of the two cylinders respectively. It is required that the outlet of the diverter collector valve is connected to the rod cavity of the two cylinders respectively when the piston rod is withdrawn in synchronization. The synchronization performance depends on the quality of the diverter valve and the leakage of the hydraulic system.
