Puerto Rico hydraulic cylinder,unidirectional cylinder manufacturer,unidirectional cylinder

(Puerto Rico unidirectional cylinder,produced by Hebei Hengyu company）

unidirectional cylinder are widely used in Puerto Rico，because of clever hydraulic energy conversion，simple structure and reliable operation，powerful torque.So our company has designed unidirectional cylinder for customers from Puerto Rico.

Introduction to unidirectional cylinder:

Do not regularly check the damage of the chrome layer of the unidirectional cylinder: completely extend the unidirectional cylinder and carefully check whether there is any surface damage such as injury, strain, welding slag, such as the surface damage position, in the unidirectional cylinder block < 20cm, and the damage depth < 5mm, should be repaired in time to prevent long-term damage to the unidirectional cylinder seal. Welding slag is strictly prohibited on the surface of the unidirectional cylinder.

The "O" ring can be used as an auxiliary seal inside the unidirectional 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 unidirectional cylinder, and can be completely sealed.

unidirectional cylinder piston rod material introduction: In general, we use 45 steel to produce unidirectional cylinder piston rod. It has a large impact force when it is used, and some good performance steel are also used in the heavy load transmission. In order to have enough work intensity when using, and can ensure normal use, this is still more critical to have a detailed understanding of the material.

Before the unidirectional 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.

Answers to some questions about unidirectional cylinder:

What is the meaning of dead volume in hydraulic cylinder?
Closed volume, also known as dead zone volume Positive displacement pump is dependent on the change of sealing working volume to achieve suction and pressure oil, in order not to make the suction and pressure oil cavity interworking, there is an oil sealing area between the suction and pressure oil cavity, when the sealing working volume passes through the oil sealing area, neither pressure oil cavity nor oil suction cavity communication, forming a closed sealing volume. The unloading groove is opened, and the grooving principle is that the sealing volume decreases and the oil pressure chamber is communicated, and the sealing volume increases and the oil suction chamber is communicated.

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.
