Paraguay hydraulic cylinder,stroke adjustable cylinder manufacturer,stroke adjustable cylinder

(Paraguay stroke adjustable cylinder,produced by Hebei Hengyu company）

stroke adjustable cylinder are widely used in Paraguay，because of excellent temperature resistance，powerful torque，no need for deceleration device.So our company has designed stroke adjustable cylinder for customers from Paraguay.

Introduction to stroke adjustable cylinder:

When the stroke adjustable cylinder needs to be stored for a period of time, please follow the recommended methods: The stroke adjustable cylinder should be stored in a dry, clean, non-corrosive gas indoor environment, pay attention to protect the stroke adjustable cylinder from internal corrosion and external damage. If the indoor requirements cannot be met, the hardened and well-drained ground should be cushioned at least 30cm, and the upper part should be covered with waterproof storage. The oil stroke adjustable cylinder should not be in direct contact with water vapor for a long time. The stroke adjustable cylinder should be placed as vertically as possible with the piston rod facing up, which minimizes corrosion due to possible condensation in the stroke adjustable cylinder and permanent deformation of the seal due to the piston and rod weight. (When the shield is stored in the shield machine, the support shoe is placed upward). Keep the oil port protective cover until the pipe is connected. For long-term storage, the protection should be added on both sides of the piston of the stroke adjustable cylinder Before working, the stroke adjustable cylinder must be run repeatedly with low pressure (greater than the starting pressure) to discharge the air in the stroke adjustable cylinder before normal work. The oil inlet and outlet and the joint must be tightly fastened with a combination pad to prevent oil leakage.

There are some honeycomb holes in the inner wall of the stroke adjustable cylinder, piston or piston rod surface. How is this formed? When we repair the stroke adjustable cylinder, we can see that there are some honeycomb holes on the inner wall of the stroke adjustable cylinder, the piston or the piston rod surface, which are caused by cavitation. Therefore, the cavitation of the stroke adjustable cylinder is targeted to prevent. Is very necessary.

When the stroke adjustable cylinder wear is serious, you can try to use an alloy scraper to shave grooves with a depth of more than 1mm on the surface of the slip injury, then clean the grooves with acetone, apply the adjusted TS311 anti-wear repair agent on the polished surface with the stroke adjustable cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the stroke adjustable cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the stroke adjustable cylinder can meet the requirements by grinding. However, the life and reliability of this repair stroke adjustable cylinder are not high.

If the stroke adjustable cylinder slips or crawls, please check whether there is astringency inside the stroke adjustable cylinder, because the internal parts of the stroke adjustable cylinder are improperly assembled, the parts are deformed, worn or the shape and position tolerance is excessive, the action resistance is too large, so that the piston speed of the stroke adjustable cylinder changes with the different stroke position, and the slip or crawl occurs. 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 stroke adjustable 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.

Answers to some questions about stroke adjustable cylinder:

Why can't the hydraulic cylinder be replaced with water?
Hydraulic oil for hydraulic transmission has a variety of requirements for viscosity, density, flow rate, and temperature, which are not available for water.

Design a hydraulic cylinder, the inner diameter of the cylinder is 100mm, what size of piston rod is best used?
This involves how much speed ratio you need, that is, the area ratio of the rod cavity and the rodless cavity, if the weight is relatively large, it is recommended that the speed ratio choose 2, that is, the piston rod diameter choose 70mm, under normal circumstances, the speed ratio choose 1.46, the piston rod diameter choose 55mm. Of course, there are many factors that affect the diameter of the piston rod, such as stroke, stroke is too long, in order to stabilize the work of the hydraulic cylinder, its diameter also needs to choose a relatively large, sometimes even non-standard products, need to choose according to the actual situation.
