(Indonesia stroke adjustable cylinder,produced by Hengyu Hydraulic Cylinder Factory）

stroke adjustable cylinder are widely used in Indonesia，because of excellent fatigue and impact resistance，no need for deceleration device，long service life.So our company has designed stroke adjustable cylinder for customers from Indonesia.

Introduction to stroke adjustable cylinder:

Before the stroke adjustable cylinder is removed, the relief valve should be loosened to reduce the pressure of the hydraulic circuit to zero, and then the power supply should be cut off to stop the hydraulic device. After loosening the oil port piping, the oil plug should be applied to plug the oil port.

When the long-stroke stroke adjustable cylinder rotates horizontally, the piston rod bends due to its own weight, causing the guide sleeve and piston to produce biased load, resulting in stroke adjustable cylinder head seal damage, oil leakage, and piston sleep in the stroke adjustable cylinder. The following measures can be taken: increase the piston plan to adjust the piston outer circle and process it into a convex drum, so that the piston can self-position, improve the force situation, and reduce and avoid pulling the stroke adjustable cylinder; The piston and the piston rod are connected with a spherical joint.

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.

The quality of the stroke adjustable cylinder can not be ignored in the purchase of the stroke adjustable cylinder. The stroke adjustable cylinder is the main component of the stroke adjustable cylinder, the single pillar for mining, the hydraulic support, the gun tube and other products, and its processing quality directly affects the life and reliability of the entire product. stroke adjustable cylinder processing requirements are high, its internal surface roughness requirements are Ra0.4 ~ 0.8μm, the coaxiality, wear resistance requirements are strict. The basic feature of stroke adjustable cylinder is deep hole processing, which has always troubled the processing personnel.

Answers to some questions about stroke adjustable cylinder:

Slide weight 35 kg exit stroke 55mm, is it suitable to use 40 cylinder diameter cylinder?
The maximum output force of the 40-bore hydraulic cylinder can reach 2 tons, and whether it can be used depends on the use scenario. In addition, the problem of mechanism stuck has nothing to do with the size of the power source, and reasonable structural design and good machining and assembly accuracy are the key.

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.
