(Kuwait stainless steel cylinder,produced by Hebei Hengyu company）

stainless steel cylinder are widely used in Kuwait，because of clever hydraulic energy conversion，simple structure and reliable operation，excellent temperature resistance.So our company has designed stainless steel cylinder for customers from Kuwait.

Introduction to stainless steel cylinder:

The stainless steel cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and does linear reciprocating motion (or swinging motion). It is simple in structure and reliable in operation. When it is used to achieve reciprocating movement, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth, so it is widely used in various mechanical hydraulic systems. The output force of the stainless steel cylinder is proportional to the effective area of the piston and the pressure difference between the two sides; The stainless steel cylinder is basically composed of stainless steel cylinder and stainless steel cylinder head, piston and piston rod, sealing device, buffer device and exhaust device. Buffer device and exhaust device depending on the specific application, other devices are essential.

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

Improve the service life of the stainless steel cylinder: it is necessary to maintain the normal clearance of the combined surface of the hydraulic components. When manufacturing or repairing the main parts of the stainless steel cylinder (such as the stainless steel cylinder block, piston rod, etc.), the assembly should be carried out in accordance with the tolerance lower limit of the assembly size, which can well reduce the occurrence of cavitation. If cavitation has occurred in the hydraulic components, only metallographic sandpaper polishing technology can be used to remove cavitation pitting and surface carbon deposits, and general fine sandpaper must not be used for polishing After the stainless steel cylinder is repaired, the hydraulic system should run smoothly for a certain period of time so that the hydraulic oil in the hydraulic system can be fully circulated; If necessary, the stainless steel cylinder inlet pipe (or return pipe) can be disassembled. Make the hydraulic oil overflow to achieve the effect of single stainless steel cylinder exhaust.

In order to ensure the service life of the stainless steel cylinder, the hydraulic system must be set up effective filtration to prevent pollution, the cleanliness of the oil should meet the ISO4406 standard, and the quality of the filtration should also meet the corresponding standards in ISO. The grade requirements of the filter are performed according to the actual working conditions of the system, but the minimum requirements are not less than 19/15 in ISO4406, that is, 24μ (β10≥75) in ISO4572.

Answers to some questions about stainless steel cylinder:

Can one hydraulic pump with two cylinders work?
A hydraulic pump with two cylinders will work. Commonly used hydraulic pump types: 1, according to whether the flow can be adjusted can be divided into: variable pump and quantitative pump. The output flow can be adjusted according to the needs of the variable pump, the flow can not be adjusted called quantitative pump. 2, according to the pump structure commonly used in the hydraulic system is divided into: gear pump, vane pump and plunger pump 3 kinds. Gear pump: small volume, simple structure, the cleanliness of the oil requirements are not strict, the price is cheaper; However, the pump shaft is subjected to unbalanced force, serious wear and leakage. Vane pump: divided into double acting vane pump and single acting vane pump. The pump has uniform flow, smooth operation, low noise, higher pressure and volumetric efficiency than gear pump, and more complex structure than gear pump.

Where is the tension cylinder used in the excavator?
Get off the inside of the frame, behind the guide wheel (steering wheel, guide wheel). Disassemble the track and take the guide wheel out to see the tensioning cylinder (track spring).
