(Holland extra long cylinder,produced by Hengyu Group)

extra long cylinder are widely used in Holland,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 Holland.

Introduction to extra long cylinder:

The definition of the minimum stable speed refers to the minimum movement speed of the extra long cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the extra long cylinder that undertakes different work has different requirements for the minimum stable speed.

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

The material of the sliding part of the extra long cylinder piston sintered casting piston will cause sintering phenomenon when subjected to large transverse load. In this case, the sliding part of the piston should be made of copper alloy or welded to such material.

Analysis of commonly used seals: The wear ring and slip ring commonly used on the extra long cylinder are generally made of polytetrafluoroethylene + graphite, because pure polytetrafluoroethylene is easy to produce plastic creep, which is only suitable for low pressure and low wear resistance conditions. If the sealing ring used is a composite material formed after adding graphite filler, the performance can be effectively improved, the ability to resist plastic creep is increased by 2 to 3 times, the initial deformation caused by the load is reduced by 30 to 60% : the rigidity is increased by 2 to 3 times: the dimensional stability under heat is increased by 2 times, and the hardness is increased by l0 to 15%.

Answers to some questions about extra long cylinder:

How to achieve hydraulic cylinder self-locking?
Hydraulic cylinder self-locking is divided into oil self-locking and mechanical self-locking. The oil self-locking is equipped with a valve to maintain pressure, so that the hydraulic oil of the cylinder does not return to the tank, and the oil chamber of the cylinder is filled with a certain pressure of oil. However, this pressure holding self-locking is not very safe and reliable, and the plunger will slowly return if there is a leak. Mechanical self-locking is to install a nut on the plunger of the cylinder, and when the cylinder rises to the required position, the nut on the cylinder plunger is rotated to the end, and the cylinder block is in contact, so that the plunger will be fixed to the required height. When it is necessary to relieve the pressure, screw the nut on again and let the plunger return to the position. This kind of cylinder has a special name, called self-locking hydraulic cylinder.

How to calculate the cross-sectional area of hydraulic cylinder?
Hydraulic cylinder cross section integral rod cavity and rodless cavity: rod cavity is cylinder inner wall cross-sectional area - piston rod cross-sectional area; The rodless cavity is the cross-sectional area of the inner wall of the cylinder. If the working pressure p and the output force F are known, the effective cross-sectional area A=F/p can be calculated.
