(Denmark tailplate hydraulic cylinder,produced by Hebei Hengyu company）

tailplate hydraulic cylinder are widely used in Denmark，because of excellent temperature resistance，powerful torque，no transmission clearance.So our company has designed tailplate hydraulic cylinder for customers from Denmark.

Introduction to tailplate hydraulic cylinder:

tailplate hydraulic cylinder daily maintenance, should focus on checking whether the piston rod surface roughness and shape and position tolerance meet the technical requirements, if the piston rod bending should be calibrated to meet the requirements or according to the physical mapping, manufactured by a professional manufacturer. If the piston rod surface coating wear, slip damage, local spalling can be adopted to remove the coating, re-chrome surface processing process.

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

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

When the tailplate hydraulic cylinder thrust is insufficient, check the hydraulic circuit for leaks. Including leakage of valves and hydraulic lines. The inspection method is to check and eliminate the leakage of the hydraulic connection line by manipulating the reversing valve. Also consider the relief valve. If the relief valve enters the dirt and jams the spool, so that the relief valve is normally open, the hydraulic oil will flow directly back to the tank through the relief valve bypass, resulting in no oil in the tailplate hydraulic cylinder. If the load is too large, although the regulating pressure of the relief valve has reached the maximum rating, the tailplate hydraulic cylinder still cannot get the thrust required for continuous action without action. If the regulating pressure is low, the pressure is insufficient to achieve the required vertebra force, which is manifested as insufficient thrust. Check and adjust the relief valve at this time.

Answers to some questions about tailplate hydraulic cylinder:

How to deal with hydraulic cylinder inner wall rag, local wear serious or corrosion?
It can be reparied if the inner wall of the hydraulic cylinder is frayed, local wear or corrosion. We can use the inner wall cold melting copper technology, it has the following advantages: first, the temperature is low, the operating temperature is less than 180 degrees, and the heat affected zone is small. Second: high hardness is up to Brinell hardness 280, wear resistance and anti-corrosion. Third: the process is mature, some large coal mills have been repaired with this method and the effect is remarkable.

Why should the piston rod of the hydraulic cylinder be so precise? If you hope the cylinder has a long service cycle, then all parts need to be high-precision, not only the piston rod, but also the cylinder, the sealing groove, the surface roughness, the cylinder looks very simple. Any hydraulic factory can produce the cylinder, but the good cylinder is difficult to produce.
