Uruguay extra long cylinder

(Uruguay extra long cylinder,produced by Hebei Hengyu company)

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

Introduction to extra long cylinder:

The internal leakage of the extra long cylinder is an important indicator to measure the quality of the extra long cylinder: the internal leakage of the extra long cylinder will reduce the volumetric efficiency, increase the temperature rise of the oil, affect the positioning accuracy of the extra long cylinder, so that the extra long cylinder can not accurately and stably stop in a certain position of the extra long cylinder, so it is one of the main indicators of the extra long cylinder.

When the extra long cylinder needs to be stored for a period of time, please follow the recommended methods: The extra long cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the extra long cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil extra long cylinder should not be in direct contact with water vapor for a long time. The extra long cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the extra long cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the extra long cylinder Before working, the extra long cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the extra long cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

When installing the piston rod, it is necessary to ensure that the direction of the connecting head at the top of the piston rod should be consistent with the direction of the extra long cylinder head adn the earring (or the middle hinge shaft), and ensure the straightness of the whole piston rod during the advance and return process to prevent the phenomenon of rigid interference and causing unnecessary damage.

How to repair the extra long cylinder body when it is damaged: When the extra long cylinder has trace deformation and shallow tensile marks, the extra long cylinder is repaired by strong honing process. The heavy honing process can repair extra long cylinders up to 2.5 times out of tolerance than the original tolerance. It honed the parts with excessive size or shape error through a powerful honing machine, so that the overall size, shape tolerance and roughness of the extra long cylinder can meet the technical requirements.

Answers to some questions about extra long cylinder:

Why does excavator cylinder oil leak?
Under normal circumstances, the leakage of hydraulic cylinders is divided into internal leakage and external leakage. The external leakage is generally due to damage to the oil seal at the extended end of the piston rod and needs to be replaced. Internal leakage is generally because the oil seal on the piston is damaged, you can try to replace the oil seal here, if the replacement will also leak, then check whether there is damage to the inner wall of the cylinder.

How does the one-way solenoid valve control the hydraulic cylinder circuit?
If your cylinder is single-acting, you can use a one-way solenoid valve, such as some lifting platform hydraulic cylinder, the support valve used is one-way (two-position tee), that is, the cylinder extends out by the oil pressure top, the cylinder retracted by its own weight.
