(Tunisia supporting cylinder,produced by Hebei Hengyu company）

supporting cylinder are widely used in Tunisia，because of simple structure and reliable operation，excellent temperature resistance，no transmission clearance.So our company has designed supporting cylinder for customers from Tunisia.

Introduction to supporting cylinder:

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

supporting cylinder daily maintenance, should focus on checking whether the piston rod surface roughness and shape and position tolerance meet the technical requirements, if the piston rod bending should be calibrated to meet the requirements or according to the physical mapping, manufactured by a professional manufacturer. If the piston rod surface coating wear, slip damage, local spalling can be adopted to remove the coating, re-chrome surface processing process.

The definition of the minimum starting pressure of the supporting cylinder refers to the minimum working pressure of the supporting cylinder in the no-load state, which is a comprehensive index reflecting the manufacturing and assembly accuracy of the supporting cylinder parts and the size of the sealing friction.

When installing the supporting cylinder pipe, the pipe should be cleaned after installation, and should not pass through the supporting cylinder block, and the by-pass pipe must be installed in front of the oil port of the supporting cylinder block. This is important. Otherwise, the foreign body in the pipeline will enter the supporting cylinder, and once it enters, it is difficult to exclude it, but it becomes a foreign body transported to the supporting cylinder. Moreover, when cleaning, the removal method of foreign bodies entered in the installation pipeline operation should be considered. In addition, the corrosion in the pipe should be pickling and other procedures before the pipe installation, and the rust must be completely removed.

Answers to some questions about supporting 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.

What material should be selected to seal the cylinder?
The choice of material for sealing is related to the working environment, strength, and medium of your equipment.
