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

trunnion cylinder are widely used in Qatar，because of long service life，high work efficiency，smooth movement.So our company has designed trunnion cylinder for customers from Qatar.

Introduction to trunnion cylinder:

The coordination of the sliding parts of the trunnion cylinder itself should not be too tight, the sealing friction force should not be too large, and H8 / f8 coordination should be selected between the piston rod and the guide sleeve; Check whether the size of the sealing ring is processed strictly according to the standard; If the V-shaped sealing ring is used, the sealing friction should be adjusted to a moderate degree.

In order to ensure the service life of the trunnion cylinder, the hydraulic system must be set up effective filtration to prevent pollution, the cleanliness of the oil should meet the ISO4406 standard, and the quality of the filtration should also meet the corresponding standards in ISO. The grade requirements of the filter are performed according to the actual working conditions of the system, but the minimum requirements are not less than 19/15 in ISO4406, that is, 24μ (β10≥75) in ISO4572.

trunnion cylinder diameter, rod diameter, stroke determination: Choose national standards or other standards trunnion cylinder, avoid the selection of non-standard size, otherwise the difficulty of processing and manufacturing costs will be increased. The length of the trunnion cylinder guide is determined by the length of the stroke. Check the strength of trunnion cylinder, piston rod, screw, etc. according to the working pressure or load. At the same time, working pressure, ambient temperature, working medium and running speed are also the key to selecting seals.

If the trunnion cylinder slips or crawls, please check whether there is astringency inside the trunnion cylinder, because the internal parts of the trunnion cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, the action resistance is too large, so that the piston speed of the trunnion cylinder changes with the different stroke position, and the slip or crawl occurs. Most of the reasons are due to poor assembly quality of parts, surface scars or sintered iron filings, so that the resistance increases, the speed decreases. For example, the piston is different from the piston rod or the piston rod is bent, the trunnion cylinder or the piston rod is offset from the mounting position of the guide rail, and the sealing ring is too tight or too loose. The solution is to repair or adjust, replace damaged parts and remove iron filings.

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.

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.
