(Saudi Arabia trunnion cylinder,produced by Hebei Hengyu company）

trunnion cylinder are widely used in Saudi Arabia，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed trunnion cylinder for customers from Saudi Arabia.

Introduction to trunnion cylinder:

If the piston rod and trunnion cylinder are stuck or the trunnion cylinder is blocked, at this time, no matter how to operate, the trunnion cylinder does not move or has little action. At this time, check whether the piston and piston rod seal is too tight, whether it enters the dirt and gum deposits: whether the shaft line of the piston rod and the trunnion cylinder is in the center, whether the wearing parts and seals are invalid, and whether the load is too large.

Because of the slightly complex structure of the buffer trunnion cylinder, sometimes there will be problems, such as when the trunnion cylinder with the buffer device is started in reverse, the piston often stops temporarily or reverses. Elimination method: The orifice of the check valve is too small, so that the amount of oil entering the buffer chamber is too small, and even a vacuum occurs, so the above fault phenomenon will occur when the buffer plunger leaves the end cover. In this regard, the orifice of the check valve should be increased.

trunnion cylinder installation precautions: Before installing the trunnion cylinder into the system, the parameters on the trunnion cylinder label should be compared with the parameters when ordering. The base of the trunnion cylinder must have sufficient stiffness, otherwise the trunnion cylinder will bend upward into a bow when pressurized, so that the piston rod will bend.

In use, the trunnion 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 trunnion cylinder.

Answers to some questions about trunnion cylinder:

How to calculate the speed of cylinder weight decline?
To reduce the weight of the cylinder, the necessary condition is that the weight of the piston rod + external load is greater than the friction between the seal ring and the cylinder. There are many reasons for this, first of all, consider the reasons of the cylinder itself, the piston in the cylinder and the sealing ring on the piston rod will play a reaction force on the weight of the cylinder (because of friction), which depends on the tightness of the sealing ring and the cylinder. Secondly, what is connected under the piston rod of the cylinder and how much weight there is. And the way the cylinders are arranged, is it completely vertical. Anyway, in fact, the most important thing is to see how much the bore of the oil hole of the piston rod cavity of your cylinder is. For example, if the hole in the lower chamber of the cylinder is small, as thin as a needle, then its descent rate will be slow.

Where is the tension cylinder used in the excavator?
Get off the inside of the frame, behind the guide wheel (steering wheel, guide wheel). Disassemble the track and take the guide wheel out to see the tensioning cylinder (track spring).
