self-locking hydraulic cylinder are widely used in Oman，because of no need for deceleration device，long service life，smooth movement.So our company has designed self-locking hydraulic cylinder for customers from Oman.

Introduction to self-locking hydraulic cylinder:

At the rated pressure, the thrust of the self-locking hydraulic cylinder is determined by what factors: at the rated pressure of the oil pump, the work done by the self-locking hydraulic cylinder is related to the diameter of the self-locking hydraulic cylinder, but not to the stroke of the self-locking hydraulic cylinder. Moreover, the larger the self-locking hydraulic cylinder diameter, the larger the area, and the greater the pressure obtained. To this point, we should have a correct understanding and clear understanding, so as to avoid problems in the use of the self-locking hydraulic cylinder.

The "O" ring can be used as an auxiliary seal inside the self-locking hydraulic cylinder, and the elastic force of the "O" ring makes the sealing slip ring close to the sealing surface, generating sealing pressure to achieve sealing. When the internal hydraulic pressure increases, the "O" ring will further deform and squeeze the slip ring, thereby increasing the sealing pressure and improving the sealing performance. The structure has the characteristics of low friction coefficient, good wear resistance, automatic compensation for wear and absorption of hard particles in the self-locking hydraulic cylinder, and can be completely sealed.

Before the self-locking hydraulic 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.

self-locking hydraulic cylinder installation precautions: Before installing the self-locking hydraulic cylinder into the system, the parameters on the self-locking hydraulic cylinder label should be compared with the parameters when ordering. The base of the self-locking hydraulic cylinder must have sufficient stiffness, otherwise the self-locking hydraulic cylinder will bend upward into a bow when pressurized, so that the piston rod will bend.

Answers to some questions about self-locking hydraulic 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.

Can multiple identical hydraulic cylinders be supplied with the same supply line?
This can be connected, but there is a disadvantage, that is, the hydraulic cylinder with the minimum pressure is extended first, and then the pressure is higher, and then the higher, until all the hydraulic cylinders are extended, which may not meet the requirements of field use.
