(Bolivia stainless steel cylinder,produced by Hengyu Group）

stainless steel cylinder are widely used in Bolivia，because of no need for deceleration device，high work efficiency，excellent fatigue and impact resistance.So our company has designed stainless steel cylinder for customers from Bolivia.

Introduction to stainless steel cylinder:

stainless steel cylinder head explanation: low pressure castings, medium and low pressure with HT300 gray iron, medium and high pressure with 35, 45 steel. When the stainless steel cylinder head itself is the guide sleeve of the piston rod, the stainless steel cylinder head is best cast iron. At the same time, brass, bronze or other wear-resistant materials should be fused on the guide surface. If the guide sleeve is pressed into the stainless steel cylinder head, the guide sleeve shall be wear-resistant cast iron, bronze or brass.

stainless steel cylinder diameter, rod diameter, stroke determination: Choose national standards or other standards stainless steel cylinder, avoid the selection of non-standard size, otherwise the difficulty of processing and manufacturing costs will be increased. The length of the stainless steel cylinder guide is determined by the length of the stroke. Check the strength of stainless steel cylinder, piston rod, screw, etc. according to the working pressure or load. At the same time, working pressure, ambient temperature, working medium and running speed are also the key to selecting seals.

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.

Because of the slightly complex structure of the buffer stainless steel cylinder, sometimes there will be problems, such as when the stainless steel cylinder with the buffer device is started in reverse, the piston often stops temporarily or reverses. Elimination method: The orifice of the check valve is too small, so that the amount of oil entering the buffer chamber is too small, and even a vacuum occurs, so the above fault phenomenon will occur when the buffer plunger leaves the end cover. In this regard, the orifice of the check valve should be increased.

Answers to some questions about stainless steel cylinder:

What is the cause of sound and vibration when the hydraulic cylinder is under load?
The main reason 1) may be that the load machinery has stuck phenomenon, and the resistance is large. 2) The hydraulic oil is not enough, or the filter is blocked by dirty things, and the oil is flooded. 3) There is a problem with the pump.

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.
