Uruguay hydraulic cylinder,single rack cylinder manufacturer,single rack cylinder

(Uruguay single rack cylinder,produced by Hengyu Hydraulic Co., Ltd）

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

Introduction to single rack cylinder:

The main role of the single rack cylinder: the single rack cylinder is an executive element in the hydraulic transmission system, which is an energy conversion device that converts hydraulic energy into mechanical energy. The hydraulic motor realizes continuous rotary motion, while the single rack cylinder realizes reciprocating motion. The structure of the single rack cylinder has three categories: piston single rack cylinder, plunger single rack cylinder, swing single rack cylinder, piston single rack cylinder and plunger single rack cylinder to achieve reciprocating linear motion, output speed and thrust, swing single rack cylinder to achieve reciprocating swing, output angular speed (speed) and torque. In addition to the single use of the single rack cylinder, two or more can be combined or used in combination with other mechanisms. To fulfill a special function. The single rack cylinder has simple structure and reliable operation, and has been widely used in the hydraulic system of machine tools.

Most of the failure of the single rack cylinder is because there is a foreign body in the single rack cylinder into the failure of the single rack cylinder, the most problematic is that it is difficult to determine when the foreign body is into the single rack 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.

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.

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 single rack cylinder action. Troubleshooting method: Replace the rubber hose.

Answers to some questions about single rack cylinder:

What is a mold core cylinder?
Simple plastic parts can be directly pushed out by the ejector rod after injection molding, complex plastic parts can not be directly pushed out by the ejector rod after injection molding, to make the interference part active, control its position through the cylinder (injection molding into the mold, so that the shape of the plastic parts meet the demand, exit after opening the mold, so that the plastic parts are smoothly pushed out), This kind of cylinder is the mold core cylinder.

How many boom cylinders, bucket rod cylinders and bucket cylinders are there in a small single-bucket excavator?
one for bucket, one for forearm, only one piece for a small excavator under the big arm, two pieces for medium and large excavator.
