Argentina extra long cylinder

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

extra long cylinder are widely used in Argentina,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 Argentina.

Introduction to extra long cylinder:

The commonly used buffer structure of the extra long cylinder is composed of a piston boss and a extra long cylinder head groove. When the piston moves close to the extra long cylinder head, it gradually enters the groove, and the oil in the groove is extruded through the gap between the boss and the groove, which increases the oil return resistance, produces the braking effect and realizes the buffer. Generally, a buffer mechanism should be used when the pressure is above 10MP.

The cavitation of the extra long cylinder has a great influence, and to avoid it, it is necessary to use the hydraulic oil reasonably and ensure the quality of the hydraulic oil. If the anti-foam property of the oil is poor, it is easy to produce foam, resulting in cavitation. Secondly, the change frequency of oil pressure is too fast and too high, which will also directly cause the formation of bubbles and accelerate the rupture rate of bubbles. The test shows that the speed of cavitation will be accelerated in the part with high frequency of pressure change. For example, at the inlet and outlet of the extra long cylinder, due to the relatively high frequency of pressure changes, the degree of cavitation is also relatively higher than that of other parts. In addition, overheating of the oil will also increase the probability of cavitation.

When the extra long cylinder is disassembled due to oil leakage and other faults, the position of the piston should be moved to any end position of the extra long cylinder by applying liquid pressure. Improper tapping and sudden drop should be avoided during disassembly.

The pressure, temperature, medium and speed of different types of seals are not the same, water-ethylene glycol medium (HFC) can not be sealed with polyurethane, it can only use rubber seal; When the extra long cylinder is running fast, it must be sealed with slip ring, such as Sterseal, Glairing, GD1000K, TDI, etc., when the running speed is slow, Yx, U, V combination seals can be used; Fluorine rubber seal is used in high temperature and high pressure environment; When the running speed is fast, the buffer sleeve and buffer valve must be considered.

Answers to some questions about extra long cylinder:

How to store hydraulic cylinder?
After cleaning the hydraulic cylinder with diesel or kerosene, apply lubricating oil and wrap it in oil paper, preferably in a wooden box, and store it in a dry and non-corrosive environment. The outer surface and inner surface of the hydraulic cylinder are sprayed with diesel oil, and the inner layer is covered with cloth and the outer coating of anti-rust oil is good. Put it in a dry place, clean it with diesel oil, and then apply a layer of anti-rust inside and outside the butter.

How to use a solenoid valve to control the expansion of a cylinder? Doesn't the solenoid valve only control on/off?
Use the solenoid valve P into A-B (generally equipped with oil circuit board) to connect the oil inlet interface at both ends of the cylinder, and the solenoid valve can be realized by power off (refer to the solenoid valve 2B2L, different solenoid valve actions are different).
