(Ethiopia fig support cylinder,produced by Hengyu Group）

fig support cylinder are widely used in Ethiopia，because of powerful torque，clever hydraulic energy conversion，simple structure and reliable operation.So our company has designed fig support cylinder for customers from Ethiopia.

Introduction to fig support cylinder:

fig support cylinder diameter, rod diameter, stroke determination: Choose national standards or other standards fig support cylinder, avoid the selection of non-standard size, otherwise the difficulty of processing and manufacturing costs will be increased. The length of the fig support cylinder guide is determined by the length of the stroke. Check the strength of fig support cylinder, piston rod, screw, etc. according to the working pressure or load. At the same time, working pressure, ambient temperature, working medium and running speed are also the key to selecting seals.

The meaning of the fig support cylinder model marked by the fig support cylinder manufacturer: for example, 160/100-1150, its meaning: from a professional point of view, 160 refers to the fig support cylinder diameter, which is 160mm, and the 100 behind refers to the rod diameter, which is 100mm. The 1150 refers to the fig support cylinder stroke, which is 1150mm. Therefore, on this point, we should have a correct understanding and can not make mistakes.

In use, the fig support cylinder should try to avoid the friction iron powder or iron filings formed by buffering the plunger. When the matching gap of the buffer device is small and the transverse load on the piston rod is large, the sintering phenomenon may be caused. These friction iron powder or the metal fragments that have fallen off as a result of sintering will remain in the fig support cylinder.

Protection of the fig support cylinder surface: During the dismantling process, safety protection should be carried out on the fig support cylinder to prevent objects from falling and welding slag from falling to the surface, causing damage to the fig support cylinder surface. In the process of propulsion, the damaged pipe segments should be prevented from falling and smashing, and the slurry remaining on the surface of the fig support cylinder should be cleaned up in time.

Answers to some questions about fig support 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.

What is the meaning of dead volume in hydraulic cylinder?
Closed volume, also known as dead zone volume Positive displacement pump is dependent on the change of sealing working volume to achieve suction and pressure oil, in order not to make the suction and pressure oil cavity interworking, there is an oil sealing area between the suction and pressure oil cavity, when the sealing working volume passes through the oil sealing area, neither pressure oil cavity nor oil suction cavity communication, forming a closed sealing volume. The unloading groove is opened, and the grooving principle is that the sealing volume decreases and the oil pressure chamber is communicated, and the sealing volume increases and the oil suction chamber is communicated.
