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

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

Introduction to trunnion cylinder:

In order to ensure the service life of the trunnion cylinder, the medium used must not be mixed with impurities and stolen goods, so as to avoid scratching the inner arm of the trunnion cylinder, causing damage to the seal and causing leakage in the trunnion cylinder. It is required that the filtration accuracy of the system is not less than 80μm, the oil pollution is strictly controlled, the hydraulic oil is kept clean, the performance of the hydraulic oil is regularly checked, and the necessary fine filtration or replacement of the new working hydraulic oil is carried out.

If it is found that the trunnion cylinder lubrication is poor or the trunnion cylinder bore processing is abnormal, it is necessary to feedback the situation to the manufacturer, because the piston and the trunnion cylinder, the guide rail and the piston rod have relative movement, if the lubrication is poor or the trunnion cylinder bore is abnormal, it will aggravate the wear and reduce the straightness of the trunnion cylinder center line. In this way, when the piston works in the trunnion cylinder, the friction resistance will be large and small, resulting in slip or crawling. The solution is to repair and grind the trunnion cylinder first, and then prepare the piston according to the matching requirements, repair and grind the piston rod, and configure the guide sleeve.

The daily inspection of the trunnion cylinder includes: checking the connection of the trunnion cylinder and the pipe joint for leaks. Check the trunnion cylinder rod for leaks. Check the trunnion cylinder connection for leaks. When the trunnion cylinder moves, the work is normal and smooth. Whether the trunnion cylinder has internal leakage.

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.

Answers to some questions about trunnion cylinder:

Hydraulic system schematic diagram, pipeline identification S and L, respectively corresponding nominal diameters? 16S is equivalent to DN12 high-pressure cylinder, and 15L means what?
16S refers to the high pressure series, outer diameter 16x2 steel pipe, the corresponding sleeve nut is M24X1.515L is the low pressure series, the outer diameter of 15x1.5 steel pipe, the corresponding sleeve nut is M22X1.5.

Why is the hydraulic cylinder of the larger excavator arm upside down?
The weight of the excavating arm of a large excavator will be very heavy, and an oil cylinder has two cavities, one is a rod cavity, and the other is a rodless cavity. The lifting force of the excavator is the product of the ortho-projection area of the piston rod cavity by the oil pressure, so the strength of the rodless cavity is much greater than that of the rod cavity. And the parallel bars with the piston rod facing down are also conducive to assembly and future maintenance. So a large excavator has to keep the cylinder facing down.
