(Vietnam trunnion cylinder,produced by Hengyu Group）

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

Introduction to trunnion cylinder:

Improve the service life of the trunnion cylinder: it is necessary to maintain the normal clearance of the combined surface of the hydraulic components. When manufacturing or repairing the main parts of the trunnion cylinder (such as the trunnion cylinder block, piston rod, etc.), the assembly should be carried out in accordance with the tolerance lower limit of the assembly size, which can well reduce the occurrence of cavitation. If cavitation has occurred in the hydraulic components, only metallographic sandpaper polishing technology can be used to remove cavitation pitting and surface carbon deposits, and general fine sandpaper must not be used for polishing After the trunnion cylinder is repaired, the hydraulic system should run smoothly for a certain period of time so that the hydraulic oil in the hydraulic system can be fully circulated; If necessary, the trunnion cylinder inlet pipe (or return pipe) can be disassembled. Make the hydraulic oil overflow to achieve the effect of single trunnion cylinder exhaust.

Protection of the trunnion cylinder surface: During the dismantling process, safety protection should be carried out on the trunnion cylinder to prevent objects from falling and welding slag from falling to the surface, causing damage to the trunnion 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 trunnion cylinder should be cleaned up in time.

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.

When the trunnion cylinder is kept, do not pay attention to keeping the oil port open, which will produce the condition of accepting foreign bodies at all times, which is absolutely not allowed. Storage must be filled with anti-rust oil or working oil, and plug.

Answers to some questions about trunnion cylinder:

What adhesive should be used when the cylinder is cracked?
There is a kind of cast iron glue, industrial products market can buy, A, B formula, that is, a tube is A, a tube is B, when used proportionally prepared, check the instructions. Polish the glue after it dries, and then grind it again.

How does the cylinder of the shearing machine work?
Plate shear is a machine that cuts a sheet with a reciprocating straight motion from one blade to another. Through the moving upper blade and the fixed lower blade, the shear force is applied to the metal sheet of various thicknesses with a reasonable blade gap, so that the sheet is broken and separated according to the required size. Shearing machine belongs to one of the forging machinery, the main role is the metal processing industry. Products are widely used in aviation, light industry, metallurgy, chemical industry, construction, shipbuilding, automobile, electric power, electrical appliances, decoration and other industries to provide the required special machinery and complete sets of equipment. Working principle: The hydraulic system is used to drive the hydraulic cylinder to output a strong shear force to complete the shearing work.
