(Switzerland forklift hydraulic cylinder,produced by Hengyu Hydraulic Cylinder Factory)

forklift hydraulic cylinder are widely used in Switzerland,because of no need for deceleration device,no transmission clearance,excellent temperature resistance.So our company has designed forklift hydraulic cylinder for customers from Switzerland.

Introduction to forklift hydraulic cylinder:

The advantages and disadvantages of the forklift hydraulic cylinder: the surface of the forklift hydraulic cylinder by painting, coating protection treatment, bright luster is not easy to rust, all raw materials of the forklift hydraulic cylinder through the top heat treatment, high manufacturing precision, belongs to the precision machinery, has a simple structure, stable quality, high mechanical efficiency, easy to achieve automation and many other advantages. However, hydraulic technology also has the shortcomings of oil leakage, oil temperature change affecting the control of running speed, noise, expensive cost and high maintenance cost.

If the piston rod and forklift hydraulic cylinder are stuck or the forklift hydraulic cylinder is blocked, at this time, no matter how to operate, the forklift hydraulic 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 forklift hydraulic cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

Analysis of commonly used seals: The wear ring and slip ring commonly used on the forklift hydraulic 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%.

Do not enter foreign bodies when installing the forklift hydraulic cylinder block. The place where the installation operation is carried out, the conditions are not good, and foreign bodies can be entered unconsciously. Therefore, the installation site must be cleaned up around, especially the place where the parts are placed must be cleaned, so that there is no dirt.

Answers to some questions about forklift hydraulic cylinder:

Why does the hydraulic cylinder rebound after the rod cavity is extended into place?
The reason is that after the rod cavity is extended into place, the rod cavity and the rodless cavity are connected, so that the cylinder moves towards the rod cavity. After connecting, it is equivalent to the hydraulic oil directly driving the cylinder with an area equal to the piston rod. After the end of this problem, it is estimated that the seal is not very good, and the two cavities are connected after the pressure is increased to a certain extent; Or there is a problem in the valve, so that the two chambers are connected after reaching a certain pressure. Other phenomena: If the load is increased to a certain extent, no matter which side of the solenoid valve is energized, the cylinder will move to the rod cavity.

How is the cylinder of hydraulic cylinder processed?
As the main parts of hydraulic cylinder, mining single pillar, hydraulic support, gun barrel and other products, its processing quality directly affects the life and reliability of the whole product. Cylinder processing requirements are high, the internal surface roughness requirements are Ra0.4 ~ 0.8&um, the coaxiality, wear resistance requirements are strict. The basic feature of cylinder is deep hole processing, which has always troubled the processing personnel. Due to the residual compressive stress on the surface of the surface layer, the rolling machining is helpful to seal the small cracks on the surface and prevent the expansion of erosion. Thus, the corrosion resistance of the surface can be improved, and the fatigue crack can be delayed or expanded, and the fatigue strength of the cylinder can be improved.
