(Jordan adjustable stroke cylinder,produced by Hengyu Group）

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

Introduction to adjustable stroke cylinder:

The pressure, temperature, medium and speed of different types of seals are not the same, water-ethylene glycol medium (HFC) can not be sealed with polyurethane, it can only use rubber seal; When the adjustable stroke cylinder is running fast, it must be sealed with slip ring, such as Sterseal, Glairing, GD1000K, TDI, etc., when the running speed is slow, Yx, U, V combination seals can be used; Fluorine rubber seal is used in high temperature and high pressure environment; When the running speed is fast, the buffer sleeve and buffer valve must be considered.

When the adjustable stroke cylinder is in use, once the seal and guide support ring are found to be defective, the seal with the same structural form and appropriate material should be replaced according to the structural form of the adjustable stroke cylinder seal to be repaired, so as to minimize the thickness of the oil film between the seal and the sealing surface and reduce the leakage of the seal.

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

When the adjustable stroke 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 adjustable stroke cylinder inner diameter copying plate, and scrape it flat vigorously to ensure compaction and higher than the inner surface of the adjustable stroke cylinder. After curing, polish to leave a finishing margin. Finally, the overall size, shape tolerance and roughness of the adjustable stroke cylinder can meet the requirements by grinding. However, the life and reliability of this repair adjustable stroke cylinder are not high.

Answers to some questions about adjustable stroke cylinder:

What is the difference between hydraulic piston cylinder and plunger cylinder?
The force surface of the piston cylinder is a rod cavity and a rodless cavity, and the force surface of the plunger cylinder is the plunger, the spring return single-acting piston cylinder can also rely on the external force of the spring to achieve return, the double-acting piston cylinder can produce tension, and the plunger cylinder only produces thrust without tension.

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.
