(Ethiopia trunnion cylinder,produced by Hengyu Group）

trunnion cylinder are widely used in Ethiopia，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed trunnion cylinder for customers from Ethiopia.

Introduction to trunnion cylinder:

In the case of serious wear on the inner surface of the trunnion cylinder, or when there is a deep longitudinal tensile mark, it should be mapped according to the physical object and re-produced by the professional manufacturer according to the trunnion cylinder manufacturing process for replacement. The trunnion cylinder can also be repaired with TS311 antiwear repair agent. TS311 anti-wear repair agent is mainly used for the repair of worn and slipped metal parts.

The cavitation of the trunnion cylinder has a great influence, and to avoid it, it is necessary to use the hydraulic oil reasonably and ensure the quality of the hydraulic oil. If the anti-foam property of the oil is poor, it is easy to produce foam, resulting in cavitation. Secondly, the change frequency of oil pressure is too fast and too high, which will also directly cause the formation of bubbles and accelerate the rupture rate of bubbles. The test shows that the speed of cavitation will be accelerated in the part with high frequency of pressure change. For example, at the inlet and outlet of the trunnion cylinder, due to the relatively high frequency of pressure changes, the degree of cavitation is also relatively higher than that of other parts. In addition, overheating of the oil will also increase the probability of cavitation.

trunnion cylinder hydraulic oil selection: The recommended working oil viscosity of the trunnion cylinder is 10 ~ 110cSt (1.8 ~ 15E), ISO VG46 hydraulic oil. The normal working oil temperature is 10 ~ 70℃, and the ambient temperature is in the range of -20 ~ 80℃. When the ambient temperature and service temperature are low, the hydraulic oil with lower viscosity can be selected.

When the long-stroke trunnion cylinder rotates horizontally, the piston rod bends due to its own weight, causing the guide sleeve and piston to produce biased load, resulting in trunnion cylinder head seal damage, oil leakage, and piston sleep in the trunnion cylinder. The following measures can be taken: increase the piston plan to adjust the piston outer circle and process it into a convex drum, so that the piston can self-position, improve the force situation, and reduce and avoid pulling the trunnion cylinder; The piston and the piston rod are connected with a spherical joint.

Answers to some questions about trunnion cylinder:

How to repair if hydraulic shears cylinder oil leakage?
The hydraulic cylinder is generally disassembled and the sealing ring is replaced. There are generally two ways to install the ends of the hydraulic cylinder. The larger hydraulic cylinder is mostly flanged disc type, which is screwed to the middle cylinder block by several bolts, the bolts are removed, and the cylinder head is slowly pulled out. The smaller hydraulic cylinder, the cylinder block and the head itself are threaded, and the rotating end cap can be removed from the cylinder block. If you do not understand the hydraulic cylinder, it is best to ask someone to deal with it. It is easy to damage the sealing ring and internal surface during disassembly.

How does the variable amplitude cylinder work?
The variable amplitude cylinder is generally an engineering hydraulic cylinder connected by the front and back earrings, and the telescopic expansion of the hydraulic cylinder changes the Angle of the arm of the lifting machinery to achieve the role of the variable amplitude, according to the role it plays is called the variable amplitude cylinder, and there is no variable amplitude hydraulic cylinder in the classification of hydraulic cylinders.
