Morocco hydraulic cylinder,single rack cylinder manufacturer,single rack cylinder

(Morocco single rack cylinder,produced by Hebei Hengyu company）

single rack cylinder are widely used in Morocco，because of excellent fatigue and impact resistance，smooth movement，high work efficiency.So our company has designed single rack cylinder for customers from Morocco.

Introduction to single rack cylinder:

We can not just consider the price and ignore the quality when we purchase the single rack cylinders. Now some manufacturers produce unqualified products in order to reduce costs, the piston rod is not adjusted, the rod coating is not enough, the single rack cylinder finish can not reach, the guide sleeve should use copper, but instead of ductile iron, although the cost is reduced, the quality of the single rack cylinder is not required.

If the single rack cylinder is sliding or crawling (stop and go), check whether there is any astringency inside the single rack cylinder. The internal parts of the single rack 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 single rack 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 single rack 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 single rack cylinder bore processing is out of whack. Because the piston and single rack cylinder, guide rail and piston rod are relative If the single rack 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 single rack cylinder weight composition and calculation. The weight of the single rack cylinder is composed of the single rack cylinder diameter, the outer diameter and weight of the single rack 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 single rack cylinder is in use, once the seal and guide support ring are found to be defective, the seal with the same structural form and appropriate material should be replaced according to the structural form of the single rack cylinder seal to be repaired, so as to minimize the thickness of the oil film between the seal and the sealing surface and reduce the leakage of the seal.

Repair method of small range wear of oil single rack cylinder: 1. Use oxygen-acetylene flame to bake the scratched part (master the temperature, avoid surface annealing), bake the oil on the metal surface all the year round until no sparks splash; 2. The scratched part is treated with an Angle grinder, the grinding depth is more than 1 mm, and the groove is polished along the guide rail, preferably a dovetail groove. Scratch both ends of the drilling deeper, change the force situation; 3. Clean the surface with absorbent cotton dipped in acetone or anhydrous ethanol.

Answers to some questions about single rack cylinder:

How does the variable amplitude cylinder work?
The variable amplitude cylinder is generally an engineering hydraulic cylinder connected by the front and back earrings, and the telescopic expansion of the hydraulic cylinder changes the Angle of the arm of the lifting machinery to achieve the role of the variable amplitude, according to the role it plays is called the variable amplitude cylinder, and there is no variable amplitude hydraulic cylinder in the classification of hydraulic cylinders.

Where's the hydraulic cylinder bleed valve?
There is a vent hole at the top of the cylinder next to the intake pipe. Generally, it can be used, and the air in the cylinder can be naturally drained after several moves.
