steering power cylinder are widely used in Mexico，because of powerful torque，excellent temperature resistance，no transmission clearance.So our company has designed steering power cylinder for customers from Mexico.

Introduction to steering power cylinder:

If the steering power cylinder is sliding or crawling (stop and go), check whether there is any astringency inside the steering power cylinder. The internal parts of the steering power 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 steering power 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 steering power 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 steering power cylinder bore processing is out of whack. Because the piston and steering power cylinder, guide rail and piston rod are relative If the steering power 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 steering power cylinder weight composition and calculation. The weight of the steering power cylinder is composed of the steering power cylinder diameter, the outer diameter and weight of the steering power 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 "O" ring can be used as an auxiliary seal inside the steering power cylinder, and the elastic force of the "O" ring makes the sealing slip ring close to the sealing surface, generating sealing pressure to achieve sealing. When the internal hydraulic pressure increases, the "O" ring will further deform and squeeze the slip ring, thereby increasing the sealing pressure and improving the sealing performance. The structure has the characteristics of low friction coefficient, good wear resistance, automatic compensation for wear and absorption of hard particles in the steering power cylinder, and can be completely sealed.

The difference between the integral steering power cylinder and the split steering power cylinder: The integral steering power cylinder and the split steering power cylinder in the steering power cylinder are two different steering power cylinders, and they are very different. The whole steering power cylinder, which is cast in one body, is not prone to problems such as oil leakage; The split steering power cylinder is welded twice, so if it is not handled well at the welding, it is prone to problems such as oil leakage and steering power cylinder damage. Therefore, it is obvious that the answer to this question is for difference.

The definition of the minimum stable speed refers to the minimum movement speed of the steering power cylinder without crawling phenomenon when the full load is moving, it has no uniform indicator, and the steering power cylinder that undertakes different work has different requirements for the minimum stable speed.

Answers to some questions about steering power cylinder:

What is the clearance between the cylinder and the piston?
The gap between the cylinder and the piston in the radius is generally 40 wires, that is, about 0.4mm, and the gap of the cylinder with different diameters will be slightly different. Generally, the inner diameter of the cylinder is larger than the outer diameter of the piston, so as to prevent the friction between the outer surface and the inner surface of the cylinder during the operation of the piston. In order to ensure that the cylinder has a rod cavity and a rodless cavity seal, a sealing device, that is, a sealing ring, is installed on the outer surface of the piston. The sealing ring form is not exactly the same, the O-type sealing ring is generally used under low pressure, and the lip sealing ring is used under high pressure. At the same time, the outer circle of the piston is also equipped with a dust ring and a wear ring. As long as the cylinder seal fails, all the internal seals should be replaced.

Why is the cylinder not in place when the concrete pump truck changes the piston?
When the concrete pump truck changes the piston, the cylinder is not in place mainly because the transfer oil connecting the two cylinders is not completely drained. Sany and Zhonglian have a piston return switch, which can be used to back the piston to the cleaning tank. The elephant is equipped with a stop valve at the bottom of the oil cylinder, usually in the closed state, when opened, the piston can be returned to the cleaning tank, remember to close the valve after the piston is updated.
