Greece large long cylinder

(Greece large long cylinder,produced by Hengyu Hydraulic Co., Ltd)

large long cylinder are widely used in Greece,because of high work efficiency,excellent fatigue and impact resistance,no need for deceleration device.So our company has designed large long cylinder for customers from Greece.

Introduction to large long cylinder:

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

When using the large long cylinder product, be sure to operate safely in accordance with the specification documents provided by the manufacturer, and pay attention to protecting the large long cylinder block. If the large long cylinder block is damaged, it will cause adverse consequences: ① The material debris extruded from the scratch groove will be embedded in the seal, which may cause new scratch area marks while damaging the working parts of the seal during operation. ② Deterioration of the surface roughness of the inner wall of the large long cylinder, increase friction, easy to produce crawling phenomenon. ③ Increase the internal leakage of the large long cylinder, so that the working efficiency of the large long cylinder is reduced.

When installing the large long cylinder pipe, the pipe should be cleaned after installation, and should not pass through the large long cylinder block, and the by-pass pipe must be installed in front of the oil port of the large long cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the large long cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the large long cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.

The role of the large long cylinder in the mold industry: the large long cylinder has a variety of uses in the mold, one is that the core distance is very large, or because of the mechanism of the product, only the large long cylinder is reasonable or more cost saving. Let the side core be extracted before opening the mold. Hot runner is mainly based on the product to decide, sometimes customers require the use of hot runner, the price is more expensive, but there are many benefits, you can save raw materials, shorten the molding cycle The large long cylinder has an irreplaceable role in the heavy industry production process: it is mainly used in places that need to support heavy objects for a long time, and it can still support heavy objects when the oil pressure is removed, and it is safe and reliable. Can be used underwater, single action, load reversion, nut self-locking to make the load safer, especially in large projects, is easy to operate control and self-locking jack, designed with a safety pressure retaining device, built-in pressure relief valve to prevent overload, to protect the self-locking jack to facilitate safe operation. The connection of the device is connected by high pressure hose and threaded joint, which has the advantages of fast use and overcoming the shortcomings of fast traditional joint oil leakage. It is mainly used for equipment installation and toppling operation in various industries such as electric power, construction, machinery manufacturing, mining, railway bridge, shipbuilding and so on.

Answers to some questions about large long cylinder:

How to calculate cylinder pressure?
Hydraulic pressure area of cylinder × hydraulic pressure = output force of cylinder 200mm=20cm 100mm=10cm 15Mpa=150Kg/cm2 Cylinder thrust: 3.14×10×10 area ×150 pressure =47100Kg=47.1t cylinder pulling force: 3.14×(10×10-5×5) Area ×150 pressure =35325Kg=35.325t The above calculation did not consider the resistance of oil return, because you did not provide oil return pressure. But the impact should be small.

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.
