Ecuador yg series hydraulic cylinder,yg series hydraulic cylinder manufacturer

(Ecuador yg series hydraulic cylinder,produced by Hebei Hengyu company）

yg series hydraulic cylinder are widely used in Ecuador，because of no transmission clearance，powerful torque，clever hydraulic energy conversion.So our company has designed yg series hydraulic cylinder for customers from Ecuador.

Introduction to yg series hydraulic cylinder:

Most of the failure of the yg series hydraulic cylinder is because there is a foreign body in the yg series hydraulic cylinder into the failure of the yg series hydraulic cylinder, the most problematic is that it is difficult to determine when the foreign body is into the yg series hydraulic cylinder. After a foreign body enters, if the outer side of the sliding surface of the piston is equipped with a seal with a lip edge, then the lip edge of the seal can scrape the foreign body when working, which is beneficial to avoid scratching. However, the piston equipped with 0-shaped sealing ring has a sliding surface at both ends, and foreign bodies are sandwiched between this sliding surface, which is easy to form scars.

yg series hydraulic cylinder piston sealing is best to use Yx ring, polyurethane and polytetrafluoroethylene sealing material combination, can significantly improve the sealing performance: (I), reduce friction resistance, no crawling phenomenon; (ii) Have good dynamic and static sealing, wear resistance, long service life; (iii) The installation groove is simple, and the disassembly is simple.

If the yg series hydraulic cylinder is sliding or crawling (stop and go), check whether there is any astringency inside the yg series hydraulic cylinder. The internal parts of the yg series 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 yg series 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 yg series 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 yg series hydraulic cylinder bore processing is out of whack. Because the piston and yg series hydraulic cylinder, guide rail and piston rod are relative If the yg series 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 yg series hydraulic cylinder weight composition and calculation. The weight of the yg series hydraulic cylinder is composed of the yg series hydraulic cylinder diameter, the outer diameter and weight of the yg series 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.

The commonly used buffer structure of the yg series hydraulic cylinder is composed of a piston boss and a yg series hydraulic cylinder head groove. When the piston moves close to the yg series hydraulic cylinder head, it gradually enters the groove, and the oil in the groove is extruded through the gap between the boss and the groove, which increases the oil return resistance, produces the braking effect and realizes the buffer. Generally, a buffer mechanism should be used when the pressure is above 10MP.

Answers to some questions about yg series hydraulic cylinder:

Cylinder la-50-70st What does that mean?
Full model should be CX-LA-50-70ST, thin block cylinder, radial mounting, bore 50, stroke 70.

How to calculate the tonnage of the hydraulic press without konowing the diameter of the cylinder?
To know the tonnage of the hydraulic cylinder, you first need to know the working pressure of the hydraulic system, the inner diameter of the hydraulic cylinder and the outer diameter of the cylinder rod (the outer diameter of the cylinder rod is needed when calculating the hydraulic cylinder tension). The thrust of the hydraulic cylinder (that is, the force that the hydraulic cylinder can produce by extending out) = the cross-sectional area of the hydraulic cylinder (or the cross-sectional area of the piston) × the working pressure of the cylinder (the cross-sectional area of the piston) =pi*D^2/4= PI (take 3.14) × the square of the cross-sectional area of the piston ÷4 working pressure to see the pressure displayed on the pressure gauge when the maximum load is working.
