(Angola trailer hydraulic cylinder,produced by Hebei Hengyu company）

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

Introduction to trailer hydraulic cylinder:

When the trailer hydraulic cylinder is in use, measures should be added to prevent the intrusion of pollutants. Effective measures should be taken to control the intrusion of pollutants, such as installing high-efficiency air filters in the tank breathing holes, new oil must be filtered, etc., but also must improve the anti-pollution ability of the trailer hydraulic cylinder itself. In the seriously polluted environment, it is more important to pay attention to, such as the underground oil trailer hydraulic cylinder should use fluorine rubber (FRM) and nitrile rubber (NBR) dust ring, and the ground mechanical trailer hydraulic cylinder should use nitrile rubber dust ring; The filter device is added to the oil inlet of the trailer hydraulic cylinder of the dump truck, construction machinery, work platform and other equipment, and in order to reduce the oil inlet resistance, the flow area should be increased as much as possible, which can effectively reduce the particle pollution from the system.

At the rated pressure, the thrust of the trailer hydraulic cylinder is determined by what factors: at the rated pressure of the oil pump, the work done by the trailer hydraulic cylinder is related to the diameter of the trailer hydraulic cylinder, but not to the stroke of the trailer hydraulic cylinder. Moreover, the larger the trailer hydraulic cylinder diameter, the larger the area, and the greater the pressure obtained. To this point, we should have a correct understanding and clear understanding, so as to avoid problems in the use of the trailer hydraulic cylinder.

If the trailer hydraulic cylinder is sliding or crawling (stop and go), check whether there is any astringency inside the trailer hydraulic cylinder. The internal parts of the trailer hydraulic cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, and the action resistance is too large, so that the piston speed of the trailer hydraulic cylinder changes with the different stroke position, and there is slip or crawl. 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 trailer hydraulic 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. At the same time, check whether the lubrication is good or whether the trailer hydraulic cylinder bore processing is out of whack. Because the piston and trailer hydraulic cylinder, guide rail and piston rod are relative If the trailer hydraulic cylinder is crawling seriously, check whether air has entered the hydraulic system. Air compression or expansion can cause the piston to slip or crawl. The exclusion measures are to check the hydraulic pump, set up a special exhaust device, and quickly operate the exhaust several times in the full stroke. Check the seals at the same time, because the quality of the seals is directly related to slippage or crawling. When the O-ring is used under low pressure, compared with the U-ring, it is easy to slip or crawl because of the higher surface pressure and the larger difference between static and static friction resistance. The surface pressure of the U-shaped sealing ring increases with the increase of pressure, although the sealing effect is correspondingly improved, but the difference between static and static friction resistance is also larger, the internal pressure increases, affecting the rubber elasticity, due to the increase in the contact resistance of the lip, the sealing ring will tip over and the lip elongation, and it is also easy to cause slip or crawling trailer hydraulic cylinder weight composition and calculation. The weight of the trailer hydraulic cylinder is composed of the trailer hydraulic cylinder diameter, the outer diameter and weight of the trailer hydraulic cylinder, the rod diameter, and the weight of the accessories, so in calculation, it is to add all these together to get the specific value. However, if there are special circumstances, it may be calculated separately. This work can be carried out by yourself, but it can also be carried out by professionals, so that mistakes can be avoided.

When the trailer hydraulic cylinder wear is serious, you can try to use an alloy scraper to shave grooves with a depth of more than 1mm on the surface of the slip injury, then clean the grooves with acetone, apply the adjusted TS311 anti-wear repair agent on the polished surface with the trailer hydraulic cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the trailer hydraulic cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the trailer hydraulic cylinder can meet the requirements by grinding. However, the life and reliability of this repair trailer hydraulic cylinder are not high.

Answers to some questions about trailer hydraulic cylinder:

Slide weight 35 kg exit stroke 55mm, is it suitable to use 40 cylinder diameter cylinder?
The maximum output force of the 40-bore hydraulic cylinder can reach 2 tons, and whether it can be used depends on the use scenario. In addition, the problem of mechanism stuck has nothing to do with the size of the power source, and reasonable structural design and good machining and assembly accuracy are the key.

How to repair the bent oil cylinder correctly?
If the bending oil cylinder leaks, the most direct way is to replace the seal ring. Most of the sealing rings used by domestic bending machines are made in Taiwan and Japan, so the service life of the sealing ring is still relatively long. If the bending oil cylinder used by the customer leaks oil, then when replacing the seal ring, be sure to choose a high-quality and durable seal ring. In this way, the replaced cylinder will not leak oil for a long time.
