Portugal trailer hydraulic cylinder

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

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

Introduction to trailer hydraulic cylinder:

If air enters the hydraulic system, the trailer hydraulic cylinder will not operate normally, mainly because there is a leak in the system. At this time, check the liquid level of the hydraulic tank, the seals and fittings on the oil suction side of the hydraulic pump, and whether the oil suction filter is too dirty. If so, the hydraulic oil should be replenished, seals and fittings should be treated, and the coarse filter element should be cleaned or replaced.

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 trailer hydraulic cylinder action. Troubleshooting method: Replace the rubber hose.

Do not enter foreign bodies when installing the trailer hydraulic cylinder block. The place where the installation operation is carried out, the conditions are not good, and foreign bodies can be entered unconsciously. Therefore, the installation site must be cleaned up around, especially the place where the parts are placed must be cleaned, so that there is no dirt.

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.

Answers to some questions about trailer hydraulic cylinder:

What are the problems that cause hydraulic cylinder shaking?
1, the oil supply is not smooth, the hydraulic oil filter is half blocked. 2. The oil level in the oil storage tank is lower than the minimum oil level. 3, there is air in the hydraulic system. 4, the supply oil pump is damaged or not working properly. 5, the hydraulic oil is not replaced for a long time.

What is hydraulic cylinder internal leakage and external leakage?
The internal leakage of the hydraulic cylinder refers to the leakage of the piston head seal of the double-acting cylinder, and the leakage occurs inside the cylinder; The external leakage refers to the leakage phenomenon between the cylinder head (or cylinder guide sleeve) and the plunger rod (or piston rod) and the seal between the guide sleeve and the cylinder block, and the oil in the hydraulic cylinder leaks to the outside.
