(Bulgaria trunnion cylinder,produced by Hengyu Hydraulic Cylinder Factory）

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

Introduction to trunnion cylinder:

There are some honeycomb holes in the inner wall of the trunnion cylinder, piston or piston rod surface. How is this formed? When we repair the trunnion cylinder, we can see that there are some honeycomb holes on the inner wall of the trunnion cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the trunnion cylinder is targeted to prevent. Is very necessary.

trunnion cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the trunnion cylinder head itself is the guide sleeve of the piston rod, the trunnion cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the trunnion cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.

Repair method of small range wear of oil trunnion cylinder: 1. Use oxygen-acetylene flame to bake the scratched part (master the temperature, avoid surface annealing), bake the oil on the metal surface all the year round until no sparks splash; 2. The scratched part is treated with an Angle grinder, the grinding depth is more than 1 mm, and the groove is polished along the guide rail, preferably a dovetail groove. Scratch both ends of the drilling deeper, change the force situation; 3. Clean the surface with absorbent cotton dipped in acetone or anhydrous ethanol.

In the hydraulic system, sometimes the inner layer of the rubber hose is peeled off, so that the oil circuit is on and off, resulting in irregular trunnion cylinder action. Troubleshooting method: Replace the rubber hose.

Answers to some questions about trunnion cylinder:

What does the maximum output force of the cylinder piston mean?
The maximum output of the cylinder is related to the pressure of the hydraulic system that you link to the cylinder. For example, the rated maximum output thrust of the MOB 50 cylinder is 1.3 tons and the rated pressure is 7Mpa. That is, when the input hydraulic oil pressure of the cylinder reaches 7Mpa, the maximum output thrust of the cylinder is only 0.98 tons. When the input hydraulic pressure is only 5Mpa, the maximum output thrust of the cylinder is 1.3 tons. Because the pressure of the cylinder limit is only 7Mpa, if the oil pressure of the input system exceeds 7Mpa, the cylinder can not withstand the pressure burst, and it is damaged.

Can multiple identical hydraulic cylinders be supplied with the same supply line?
This can be connected, but there is a disadvantage, that is, the hydraulic cylinder with the minimum pressure is extended first, and then the pressure is higher, and then the higher, until all the hydraulic cylinders are extended, which may not meet the requirements of field use.
