Australia rack cylinder

(Australia rack cylinder,produced by Hebei Hengyu company)

rack cylinder are widely used in Australia,because of smooth movement,excellent fatigue and impact resistance,high work efficiency.So our company has designed rack cylinder for customers from Australia.

Introduction to rack cylinder:

Factors that should be considered when selecting the oil seal in the rack cylinder: some specific factors should be taken into account when selecting the oil seal in the rack cylinder, so as to have correct consideration and get accurate results, and then avoid wrong selection. The factors and aspects that should be taken into account are eight: rack cylinder diameter, piston rod diameter, piston rod and piston groove size, rack cylinder working pressure, rack cylinder movement speed, hydraulic system oil temperature and rack cylinder working environment.

When the rack cylinder is installed, the piston and the rack cylinder head and other parts have large mass, large size and large inertia, even if there is a lifting equipment auxiliary installation, because the specified clearance is small, no matter how hard it will be put into, therefore, the end of the piston or the rack cylinder head boss is easy to cause scars when it hits the inner surface of the rack cylinder wall. The solution to this problem: for a large number of small products, the use of autocratic assembly oriented tools during installation; For heavy, thick and large large and medium-sized rack cylinders, only careful and careful operation can be avoided.

Analysis of commonly used seals: The wear ring and slip ring commonly used on the rack 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 assembly work of the rack cylinder has a great impact on the quality of the rack cylinder: each part must be carefully cleaned before assembly; To correctly install the sealing device everywhere: when installing the sealing ring, pay attention to its installation direction to avoid oil leakage due to installation, and its lip should be equipped with a pressure oil chamber. In addition, because it is a YX-shaped sealing ring, it is necessary to pay attention to distinguish between shaft and hole use, do not install wrong; Because the sealing device is matched with the sliding surface, an appropriate amount of hydraulic oil should be applied during assembly; The special wrench should be used when the threaded coupling is tightened, and the torque should meet the standard requirements; After the piston and piston rod are assembled, it is necessary to measure whether the coaxiality and straightness on the full length are out of whack. After assembly, there should be no blocking sensation and uneven resistance when the piston assembly moves.

Answers to some questions about rack cylinder:

What are the cylinder manufacturing processes?
Hydraulic cylinder processing process: 1, cylinder: a, material preparation (seamless steel pipe) → inspection (material certificate, etc.) → tempering (outsourcing: Some parts) → car (car round, shelf mouth, boring, flange stop, etc.) → tempered hardness test → welding (welded pipe joint base, flange and other accessories) → boring or honing (rough boring, fine boring, rolling) → car (hole slot or internal and external thread) → fitter (drilling) → inspection → rust prevention storage b, material preparation (forgings) → inspection (material certificate, inspection, etc.) → welding (blank butt welding) → welding inspection → car (rough car) → quality control (outsourcing: some parts) → car (car round, shelf mouth, boring stop, flange stop, etc.)

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.
